Study Notes
Male Reproductive Whorl
- The male reproductive whorl of a flower is called the androecium.
Androecium
- An individual member of the androecium is called a stamen.
Anther Structure
- A dithecous anther typically has two anther lobes.
Sporogenous Cell Formation
- Some hypodermal cells get transformed into archesporial cells, which is a differentiation called sporogenesis.
- The sporogenous cell forms microspores in the anther.
Megasporogenesis
- The upper three megaspores degenerate during megasporogenesis.
- The functional megaspore develops into the female gametophyte.
- The functional megaspore remains in the ovule during megasporogenesis.
Female Gametophyte
- The composition of the egg apparatus in the female gametophyte includes one egg cell and two synergids.
- A total of eight nuclei are formed during the development of the female gametophyte.
