A nucleus is primarily responsible for directing all processes and reactions in a plant cell. The function of the nucleus in the plant cell is to store the plant's DNA and control the activity of the cell through protein synthesis. The nucleus is enclosed by the nuclear membrane, which has pores for the passage of RNA and proteins.

Compare and contrast endocytosis and exocytosis. please help!!!

Dmitry [639]

Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. The main similarity is that both exocytosis and endocytosis are involved in transporting big molecules across the membrane using a vesicle and needs energy. The basic differences are that : 1) Endocytosis brings materials to the inside of the cell while exocytosis takes them out. Exocytosis, on the other hand, is described as the process of fusing vesicles with the plasma membrane to release their contents to the external environment of the cell.
