- diploid phase of the life cycle
- Alternation of generations
- The two distinct reproductive phases of green plants in which stages alternate between haploid cells and diploid cells (gametophyte cells and sporophyte cells).
- Protenema
- Small green threadlike structure...develops from the spore
- rhizoid
- The "root-like" part of moss that goes down into the earth
- Archegonia
- female sex organ of moss
- Antheridia
- male sex organ of moss
- Calyptra
- A capsule covered by a cap-like remnant of the old archegonia
- embryo
- 2n (diploid tissue)...sporophyte plant

- (a.k.a. reduction division)...chromosome number (2n) in each cell is reduced in half (n)
- Sori
- form spores on underside of ferns
- Prothallium
- heart shaped gametophyte plant
- seed
- fertilized ripened ovule of a gymnosperm
- homospory
- one type of same sized spores are produced
- heterospory
- two different spores of unequal size
- microspore
- (a.k.a. pollen grain)...produced by the male
- megaspore
- produced by female (larger than the microspore)
- pollination
- the transfer of pollen from the male to the female part of a flower
- staminate cone
- male reproductive structure
- ovulate cone
- female reproductive structure
- ovule
- produced by megasporangia...developes into seed

- stored food for embryo...(refer to p. f11)
- pollen grain
- modified microspore of seed plants
- fruit
- ripened ovary containing seeds
- cotyledons
- embryonic leaves
- sepals
- small leaf-like structures, which help protect the closed flower bud
- petals
- colorful structure leading pollinators toward the reproductive parts of the flower
- stamen
- male reproductive structure (anther, filament)
- pistil
- female reproductive structure (stigma, style, ovary)
- double fertilization
- 1 sperm-->1 egg = zygote(2n)
other sperm--> 2 polar nuclei = endosperm(3n)
- double fertilization
- 1 sperm-->1 egg = zygote(2n)
other sperm--> 2 polar nuclei = endosperm(3n)
