Gymnosperms and Angiosperms

Question 1

Gymnosperms and Angiosperms

Answer 1

Vascular plants that are seed producers
gymnosperms-the seeds are produced on the surface of the reproductive structure,
angiosperms- seed enclosed within it as in fruit.

Question 2

Gymnosperms

Answer 2

“naked seed”not enclosed or protected.
Major group (divisions)
Cycadophyta (Cycads)
Ginkgophyta (Ginkgo)
Gnetophyta (ephedra is an example)
Coniferophyta (conifers/cone bearers)

Question 3

female and male heterosporous

Answer 3

microgametophyte- male, or sperm-producing gametophyte (pollen grain, contains “sperm”)
megagametophyte = female, or egg producing gametophyte (ovule)

Question 4

pollination and seeds

Answer 4

-Pollination instead of swimming sperm secondary growth (pollination faster, Pollin can’t move on its own so it travels through air not water)
-Seeds instead of spores (seeds= flowering plants, inside fruit) (spores-fungi, bacteria, nonflowering plants)

Question 5

cones

Answer 5

microspores occur in male cones and form male gametophytes
Megaspores occur in females and form female gametophytes

Question 6

cones pollination and seed.

Answer 6

pollen-bearing male cones and seed-bearing female cones

Question 7

gymnosperms and angiosperms

Answer 7

gymnosperms- The (cone), a distinguishing feature of pines and other conifers, found on all gymnosperms, (pollination)
angiosperms- are plants that produce flowers and bear their seeds in fruits.(seeds)

Question 8

shape and details of leaf (angiosperms and gymnosperms)

Answer 8

angiosperms- flat, hardwood type, (reproduction relies on animals) (seed) (plants are seasonal)
gymnosperms- needle like or scale like, softwood type (reproduction rely on the wind) (pollination) (plants are evergreen)remains green+ functional more than 1 season
