What are the two types of spores in heterosporous plants?
The two types of spores in heterosporous plants are megaspores and microspores.
What are megaspores?
Megaspores are a type of spore that is present in heterosporous plants.
What does the megaspore germinate into?
The megaspore germinates into a female gametophyte.
What are the egg cells fertilized by?
The egg cells are fertilized by sperm produced by the male gametophyte.
Name some examples of heterosporous plants.
Some examples of heterosporous plants are seed plants (gymnosperms and flowering plants), water ferns (Salviniales), spikemosses (Selaginellaceae), and quillworts (Isoetaceae).
Study Notes
Heterosporous Plants
- Heterosporous plants produce two types of spores: microspores and megaspores.
Spore Development
- Megaspores are a type of spore that develops into a female gametophyte.
- The megaspore germinates into a female gametophyte, which produces egg cells.
Fertilization
- The egg cells are fertilized by sperm cells from the male gametophyte, which develops from microspores.
Examples of Heterosporous Plants
- Ferns
- Horsetails
- Some species of conifers and flowering plants
