Q

What is the haploid generation of the alternation-of-generations life cycle of a plant? (produces gametes that unite to form a diploid zygote)

A

gametophyte

17
Q

What are plants that have no vascular tissue that either occur in moist environments or have special adaptations for living in dry locations?

A

nonvascular plants

18
Q

What are hairlike structure found on the roots of some plants that assists in anchoring the plant and also provides for some absorption of water?

A

rhizoids

19
Q

What are 5 types of plants?

A
  1. Bryophytes
  2. Lycophytes
  3. Pteridophytes
  4. Gymnosperms
  5. Angiosperms
20
Q

What plant
-Nonvascular plants
-Rhizoids
-Gametophyte dominate stage
-Gametophyte larger & photosynthetic
-Sporophyte that is dependent on the gametophyte
-Flagellated sperm (Require moisture for reproduction)
-Liverworts, hornworts, mosses

A

Bryophytes

21
Q

What are the two parts of vascular tissue?

A

xylem and phloem

22
Q

What part of vascular tissue is pecialized to transport water through stem to leaf?

A

xylem

23
Q

What part of vascular tissue is

A

specialized to move organic nutrients

24
Q

What feature qualified Cooksonia as a type of vascular plant?

A

presence of branches

25
Q

What plant
-Seedless vascular plants
-Microphylls leaves
-Sporophyte is dominate stage
-Produce spores in cone structures called strobili
-Some lycophytes have spores that grow into one type of gamete (homosporous), others produce two types of spores (heterosporous)
-Microspores (become male gametophyte) and megaspores (become female gametophyte)
-Ground pines, spike mosses, quillwort

A

Lycophytes

26
Q

What plant
-Seedless vascular plants
-True leaves and roots
-Megaphylls leaves
-Produce spores (Wind blown dispersal)
-Sporophyte dominate stage
-Sporophyte develops on gametophyte
-Horsetails, whisk ferns, and ferns

A

Pteridophytes

27
Q

What is a sporophyte embryo with stored food enclosed in a protective coat?

A

seed

28
Q

What is a structure derived from a microspore? (develops into male gametophyte)

A

pollen grains

29
Q

The process
-occurs when a pollen grain is brought into contact with a female gametophyte by wind or pollinator
-Sperm move toward female gametophyte through pollen tube
-Megaspore develops within an ovule; becomes a seed following fertilization
- No external water needed

A

pollination

30
Q

What plant
-Cones: Reproductive structure made up of scales bearing sporangia; pollen cones bear microsporangia & seed cones bear megasporangia
-Monoecious: single plant carries both male and female reproductive structures
-Dioecious: single plant produces either male or female parts
-Conifers, cycads, ginkgoes, and gnetophytes

A

Gymnosperms

31
Q

What plant
-Adaptive radiation
-Flowers: reproductive organ of a flowering plant, consisting of serval kinds of modified leaves arranged in concentric rings attached to a modified stem
-Fruit: Flowering structure consisting of one or more ripened ovaries that usually contain seeds
-Covered seeds -> result of double fertilization

A

Angiosperms
