Reproduction in Flowering Plants: Terminology and Definitions
no Term Terminology / Definition
1 Reproduction Is the ability to produce a new generation of themselves.
2 Gametophyte generation this generation is haploid and produces gametes by mitosis.
3 Sporophyte generation this generation is diploid and produces haploid spores by meiosis.
4 Monoecious Male & female gametes produced on the same plant.
5 Dioecious Male & female gametes produced on separate plants.
a process of abrupt transition from one developmental stage to another.
6 Metamorphosis: Metamorphosis can be complete (egg, larva, pupa and adult) or incomplete (egg,
nymph and adult).
A main difference between homosporous and heterosporous pteridophytes is
Homosporous that:
homosporous pteridophytes produce only one type of spores
7 & o are small in size.
Heterosporous heterosporous pteridophytes produce two types of spores:
o the small microspores.
o the large megaspores.
Angiosperm
8 Plants with flowers which produce their ovules enclosed in an ovary.
(flowing plants)
Flower Organ of sexual reproduction that contains the reproductive organs and often
attracts pollinators
