Pollen tube formation is important for sexual reproduction to occur in seed plants. Pollen tubes act as conduits to transport the male gamete cells from the pollen grain either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

Describe the movement of oxygen molecules if there were more oxygen molecules<br> outside the cell
Molodets [167]

Explanation:

Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
