Q

Explain the effect of the virus on tulip color and name the animal vector for the virus.

A

The “breaks” in the tulip color that created interest, were caused by a virus
“Broken” tulips have more complex patterns and colors
Tulip breaking virus
Virus vector- Aphid (tiny herbivore bug). The Aphid carries the virus
Carrying bugs around and infecting the plant
Anthocyanins were redistributed in the infected plants. they are the plant’s “umbrella” or “sunscreen”. Help protect it from UV radiation.
Colors start forming interesting patterns and the virus changes its color

19
Q

Explain why “broken” tulips were more expensive during Tulipmania but are not desired by contemporary breeders.

A

The “breaks” in the tulip color that created interest. Because of this “broken flowers” were rated higher than regular ones. They formed intricate patterns when they changed color. Because this was created by the virus, it is not desired by contemporary breeders. This virus weakens the tulip.

20
Q

Describe the structure of a bulb.

A

Tulip Seeds are sexual reproduction, Tulip bulbs are tiny stems and have asexual reproduction, Asexual is preferred for Tulips because it’s faster
Offsets- what bulbs create when they reproduce (kinda like other bulbs)
onces the bulb was broken, the offset produced by the bulb carried the same characteristics causing less offsets.
Virus decreased the number of offsets
A bulb is an underground stem like a tuber
Leaf and stem modifications (leafy material)
Buds surrounded by numerous fleshy leaves, with a small stem at the lower end
Ex: garlic, onion
all Stems have nodes, internodes, axillary buds

21
Q

Distinguish between annual and perennial and know which type wild tulips are.

A

Annual angiosperm
- Annual- one year
- Last growing season
- Typically less expensive to purchase but replacements needed each year
- Grow more quickly and can bloom longer in a season
- If they produce seed, they can be re=planted or come back on their own
Perennial angiosperm
- Per= extra
- perennial= extra years
- May not flower their first year but last for years without replacement
- Usually only flower part of a season (so need different plants in a garden if you want something blooming spring through fall)

22
Q

Distinguish hybridized tulips from wild species.

A

Hybridization is a type of artificial selection using two different genetic types
- Can be the same or different species
- Hybrid bulbs are from two different parent species/ varieties
- E.g. Darwin Hybrid
Technically Tulips are perennial but many centuries of hybridizing by humans has made them more like annuals
They are not native to the US and may not be as successful long-term in our soil and climate
Tulips are planted before winter or pre-chilled for 12 weeks in a refrigerator
WIld Species:
Species tulips are wild varieties
better adapt to difficult conditions, but still vulnerable to preditation

23
Q

Name threats to tulip plantings in a garden or yard.

A

Animals - chipmunks, deer, squirrels

24
Q

Describe how plant fibers are used and classified. Given an example, know the classification we discuss in class.

A

Textile fibers- used to weave cloth
Cordage fibers- used in making rope
Filling fibers- used as stuffing and upholstry in mattresses

25
Q

Cotton

A

Surface fibers
1 fruit can produce 500,000 fibers from 4 seeds
Each fiber is a single cell, from 2.5-6 cm long
Uses: textiles from 100-300 AD

26
Q

Flax

A

Bast or soft fibers
Source of linen and linseed oils
Oldest textiles discovered- 30,000 year old flax fibers from a cave in Republic of Georgia (stone- age hunter-gatherers)
Fiber- cords for binding stone tools, weaving baskets, spinning thread
Seed Oil- Paints, stains, varnishes, linoleum, oilclothes
Bodies also mummified by wrapping them with linen from Flax plant

27
Q

Discuss advantages of hemp over cotton production.

A

The fiber crop is extremely low in THC
It requires neither the irrigation nor the pesticide application that cotton does
hemp now used in clothing, bed linin, shoes, etc

28
Q

Describe how plants respond to or protect themselves from herbivory, listing examples and distinguishing between mechanical and chemical defenses.

A
  • Chemical mimicry- to trick insects into moving through the life cycle more quickly
  • Gypsy Moth larvae eat leaves of oak and other trees (chemical mimicry used on them)
  • Milkweed- Secondary chemicals make it poisonous (chemical)
  • Stinging Nettle - Modified leaves to create barbs
  • Acacia (sensitive plant)- Leaves fold in when you touch it
  • Another type of acacia has thorns (physical) and ants that live in the thorns to keep away elephants (biological)
  • Passionflower- mimicry to mimic what eggs look like
  • Holly-wax makes it hard to get on the plant (mechanical)
29
Q

Explain how herbivores sometimes overcome plant defense mechanisms. Know examples discussed in the readings and in class.

A

Giraffes will go to the top of trees where there are few thorns
Monarch caterpillar evolves milkweed- they store toxic cardiac glycosides in cell vacuoles.
Zebra Swallowtail butterfly caterpillar evolves with the paw paw
Certain bugs can become poisonous to predators

30
Q

Describe how plant chemical defense compounds (secondary metabolites) are used by human cultures and how they sometimes benefit other herbivores.

A

Secondary metabolites are most important for human cultures in medicines, foods, sustainable agriculture, and supplements
Can be used in farming to deter herbivores from crops. (ex: parasitic wasps on tobacco hornworms)
Ex:
Caffeine, nicotine, cocaine
solanaceae plant family- drugs, food, medicine (woody nightshade, eggplant, nicotine, belladonna, potato)
Salicylic acid- a hormone produced by plants under attack to stimulate immune responses/ defense can also stimulate other plant defenses
Nicotine- stimulates release of both acetylcholine and epinephrine (neurotransmitters) in humans
Stimulates release of adrenaline
Neurotoxin in animals- kills cells
Prevents incoming impulses
Eventually blocks sensory receptors
Acute cases: tremors, convulsions, death

31
Q

Name 4 ways that fruits and seeds are dispersed and give a specific example for each.

A
  • Dispersed by wind- dutchman’s pipe, seeds are carried by wind or water. Falls out after the fruit dries.
  • Dispersed by Animals- Hornbills and other birds disburse Nutmeg frugivores like Kinkajoe also disperse the seeds
  • Dispersed by water- firecracker explodes when it rains, Dutchman’s pipe.
  • Other methods- gravity, humans
32
Q

Know how attracting animals for dispersal differs from pollinator attraction [consider the reproductive parts that are involved for each].

A

Pollinators:
* bright colors, scents, mimicry, nectar guides
* Attract pollinators through female reproductive parts
Dispersers:
* fruits
* Most flowery plants use animal dispersers
* Most woody species in tropical forests produce fruits that are dispersed by animals
* Plants protect their fruits and seeds so animals won’t eat the seeds and they can still grow (seeds taste bad or the inner part of the fruit)
* Animals can eat around the seed
* Osage orange latex secretions deter some herbivory but small animals can get to the seeds after they drop

33
Q

Explain how human dispersal of plant material can have negative consequences.

A

Certain fruits and seeds might have diseases that are harmful to agriculture
Humans delivering seeds to a non-native habitat
Human-mediated dispersal is the biggest contributor to the spread of invasive species
Can be unintentional (on clothing, backpacks, footwear, hiking boots, and socks)
People plant seeds of invasive species, like Purple Loosestrife

34
Q

Explain the benefits to plants of seed dispersal by animals and predict how that might impact humans.

A
  • Medicinal resources
  • Less competition, better change of growth
  • More likely to get planted in the ground
  • Fruits!
  • Products from plants growing- wood
35
Q

Name the land animal thought to be the longest distance disperser of seeds and state how many seeds can be carried.

A

Elephants- can transport seeds up to 65 Kilometers when seeking a mate although mast seeds land within 2.5 km. Each elephant can deposit up to 3200 seeds a day.
Largest living land animal
Eat over 600 pounds of food a day
Disperse seeds- maintain genetic diversity

36
Q

Compare and contrast seed dispersal by land animals and migratory birds.

A

Birds are long-distance dispersers
These 3 different migrating bird species stored valuable seeds inside their guts over 200 km: European pied flycatcher, common redstart, common quail
Migratory birds disperse millions of seeds over the ocean between Europe and Africa and into the Canary Islands

37
Q

diploendozoochory

A

Diploendozoochory- the process of a seed being transported in the gut of multiple animals. Animal eats the seed, one animal eating the other animal. Seeds go through two digestive systems and still get dispersed
Diplo= doubled or two-fold
endo= inside
zoochory= animal seed dispersal
zoo= animal
chory= seed dispersal

38
Q

Surface Fibers

A

Found on the covering of seeds, leaves, or fruits
ex: cotton cloth is made from seed hairs covering the surface of cotton seeds

39
Q

Bast or soft fibers

A

clusters of phloem fibers found in the inner bark of dicotyledonous stems
Ex: Hemp, CBD levels are higher than THC- a genetic mutation in marijuana gives THC molecules an advantage over CBD
Ex: flax

40
Q

Hard Fibers or Leaf fibers

A

obtained from the vascular bundles or veins in leaves
consist of both xylem and phloem as well as ensheathing fibers
Monocotyledonous leaves are the usual source of hard fibers
have higher lignin content than soft fibers
ex: sisal and Manila hemp

41
Q

Hemp

A

Bast or soft fibers. (manila hemp comes from hard fibers.
Bast fiber- stem
Hemp, CBD levels are higher than THC- a genetic mutation in marijuana gives THC molecules an advantage over CBD

42
Q

Mechanical Defenses

A

Several types of plant defenses take the form of physical structures or movements. They can be enough of a deterrent to many herbivores, in some cases, harming or even killing them to significantly reduce herbivory.
ex: waxes, saps, defensive movements

43
Q

Chemical defenses

A

Chemical compounds that make the plant toxic, reduce palatability or reduce its digestibility so as to lessen its value to an herbivore

44
Q

Sisal

A

Hard or leaf fibers
used to make rope and coarse garments
today used for rope, string, and floor mats
