Unit 3 Flashcards
chap[ter 31 fungi, WIP CHAPTERS 29&30
Discuss the structure of
fungus
Mutilcelluar fungi consist of long filaments called hyphae, a continuous protoplasm all the cells within our connected and allows for rapid growth and under conditions. The fuel saw walls include also found skeletons.
- How is fungal mitosis
different from other
eukaryotes?
It happens solely within the nuclei.
- How do fungi reproduce?
through spores, either sexual or asexual
- How do fungi “eat”?
secrete digestive enzymes into surroundings and
Absorbs organic molecules produced by external digestion
What is fungi’s main
contribution to the
biosphere?
Make materials available to other organisms
* Break down cellulose and lignin from wood
* Release carbon, nitrogen, and phosphorus
- Discuss the difference in
endophytes and
mycorrhizae
Mycorrhizae are mutualitic relationships between fungi and plants,
- What is a lichen?
Symbiotic associations between fungus and photosynthetic
partner
* Cyanobacteria, green algae, or sometimes both
Which clade (group) of fungi
includes the most familiar
ones?
basidomyctes (mushrooms)
Discuss the difference in the
reproduction of
basidiomycetes and
ascomycetes.
The difference is where spores are located and where mitosis is (GET MORE SPECIFIC)
What is a Zoospore?
spores that move on their own
Discuss issues plants had to
overcome to move onto land
dying out
water loss
uv radiation
- Which generation is dominant
in nonvascular plants?
gameteophtyes
- What is the evolutionary
advantage of vascular tissue
for plants?
enhanded height and size
- How are ferns different from
moss?
Ferns are vascular plants with complex structures and a dominant sporophyte stage, while mosses are non-vascular plants with a dominant gametophyte stage and simpler structures
What are the 2 groups of
seed plants?
Gymnosperms and angiograms
- Discuss how seeds give
plants and evolutionary
advantage
The seed offers the embryo protection, nourishment, and a mechanism to maintain dormancy for tens or even thousands of years, ensuring germination can occur when growth conditions are optimal.
- What are the whorls of a
flower?
Flower parts are organized in circles called whorls
- How are fruits and seeds
dispersed?
Blowing in the wind
* Floating and drifting on water
ingestion and transportation
by birds or other vertebrates
* Hitching a ride with hooked
spines on birds and mammals
What are the 3 tissue types
in plants?
ground tissue, vascular tissue, and dermal tissue
Discuss apical and lateral
meristems
Apical Meristems:
Responsible for primary growth, which is the increase in length of the plant
Lateral Meristems: Responsible for secondary growth, which is the increase in girth or thickness of the plant.
- Which tissue moves water
in plants?
Xylem
- Which tissue moves sugars?
Phloem
What 2 factors affect the
flow of water in a plant?
transpiration (water evaporation from leaves) and water potential (the tendency of water to move)
- What is the evaporation of
water out of leaves called?
Transpiration
- Discuss the pressure-flow
hypothesis
explanation of sugars moving thouth out the plant
Which root zone contains the
apical meristem of the root?
The zone of cell division
- What is the point of
attachment of a leaf on a
stem?
a node
- Which type of modified stem
is flattened and does
photosynthesis?
phylloclade
- Which class of plants has
leaves divided into palisade
and spongy mesophyll?
Eudicot
What are the 6 major monophyletic phyla
Blastocladiomycota
* Neocallismastigomycota
* Chytridiomycota
* Glomeromycota
* Basidiomycota
* Ascomycota
Define mycologist
Someone who works with fungi, which are living organisms such as molds, yeast, and mushrooms
What is mycelium?
Is a mass of connected hyphae
