Answer:
Explanation:
The dependent variable in this case is the valuable whose value is dependent on the other variables. In this context, the dependent variable is the rate of diffusion of the molecules...how fast or how slow which is depends on the size of the molecules.
The independent variable is the usually has a direct effect on the dependent variable which in this case is the size of the molecules...how small or big...will affect their rates of diffusion.
Answer:
the male gametophyte
Explanation:
Pollen grains are structures in the seed plants (spermatophytes) which contain vegetative cells but also reproductive cells - microgametophytes. Microgametophytes produce 2 male gametes or sperm cells. Vegetative cells produce pollen tube which is involved in the transfer of sperm cells to the ovule (female structure that forms female gametes). Pollen grains are different in shape, size and color, but all of them are enveloped with hard coat that has protective role.
