Because plants go through a cycle(the cycle is seed, seedling, plant, flower and tree.) and it takes time for the plant food, water, and nutrients to go though the plant.
If someone pours salt water on a plant that is supposed to receive fresh water, the effects on the plant are swift and severe, beginning with the draining of existing water out of the plant cell.<span> Then, the cell membrane separates from the cell wall in a process known as plasmolysis. Ultimately, the plant shrivels up and no longer thrives</span>
C is most likely your answer (my bad if I am wrong)
I believe in both groups , the sperm swim from antheridia to aronia. Both are tied to water by swimming sperm that require water to reach eggs. Neither of them has pollen, seeds, flowers, or fruits. Seedless vascular plants, however, have xylem and phloem, which bryophytes lack. For seedless vascular plants Cells in diploid sporophyte such as fern from undergo meiosis, releasing haploid spores that germinate and develop into gametophytes. Bryophytes reproduce sexually by forming sperm and egg cells within separate haploid male and female gametophytes.
