Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells. With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA.

The main advantage of seed plants
(Gymnosperms and Angiosperms) is the evolution of the seed which, unlike
spore-producing plants, was not limited to wet environments. Pollen grains are
male gametophytes (sperm) which are protected from desiccation and can reach
the female organs without dependence on water. The sperm is transferred from
the pollen through the pollen tube: an extension of a cell within the pollen
grain. The process is called pollination.
