What is the name of the cellular process that divides the number of chromosomes in a cell by half? Where does this process take place?
Meisosis divides the number of chromosomes in a cell in half. This takes place in the anther and produces a pollen grain.
5
Plant growth is possible thanks to a cellular process called ______________.
Mitosis or cell division.
5
Which part of the flower will pollen stick to in order to complete pollenation?
