Cellulose is found in the cell walls of plant cells. It is permable so any substance disolveabls in water can pass through so it dose not act as a barrier. It gives the cell its strength and support. As water moves in to the cell by osmosis it stops the cell from bursting.
Answer:
Basically, Its like a Different version of a gene which are called alleles. Alleles are described as either dominant or recessive depending on their associated traits
Explanation:
The answer is the apoplast, the symplast, and the transmembrane pathway.
1. The apoplast pathway occurs through cell walls and space between cells. So, water does not cross any cell membrane as it travels this pathway.
2. The symplast pathway occurs through the continuum of cytoplasm. So, water travels through plasmodesmata which connect cells.
3. The transmembrane pathway occurs across cell membranes. So, water enters the cell on one side of the membrane and exits on the other.
