Study Notes
Non-Flowering Plant Reproduction
- Non-flowering plants mainly reproduce through spores.
Gymnosperms
- Microsporophylls, contained in cones, produce pollen.
- The trunk is the major source of starch in gymnosperms.
- The female gametophyte in gymnosperms is contained in the ovule.
Bryophytes
- Bryophytes primarily reproduce through fragmentation.
- The male and female gametophytes in gymnosperms fuse to form a zygote.
- Bryophytes can reproduce vegetatively through fragmentation, where parts of the plant break off and grow into new individuals.
Other Interesting Facts
- Starch from gymnosperms serves as a major staple food for lowland or indigenous peoples.
