Explanation:
diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
Answer:
diffusion is the process of transfer of solids as well as gaseous molecules from higher concentration to lower concentration
osmosis is the process of transfer of water molecules from higher concentration to lower concentration
nucleus is the cell organelle in which chromosomes are present
nucleoid is the region which do not have a cell membrane
if cell wall is not present then cellulose will not present in the plant and the plant's cell is not lined by hard substance
genes are the smallest unit of DNA. they are located in the DNA. they maintain the hereditary function of living organism
