Biology

Not quite remember

I easily remember

The part of a flower that produces pollen grains:

Anther

Chromosome properties of microspore mother cells:

Diploid (2n)

Meiosis of microspore mother cell produces

Four haploids (n) microspore cells also known as a tetrad

Mitosis of pollen grain nucleus will produce:

Two nuclei namely generative nucleus & tube nucleus

Microspore mother cell divides by

Meiosis

Megaspore mother cell (2n) produces four haploids (n) megaspore cells by:

Meiosis

One megaspore cells.

The number of mitosis processes to produce a cell with eight nuclei

Three mitosis process

Location of the polar nuclei:
