Question

How does the movement of substances take place into the cell? How do substances move out of the cell?

Answer 1

I think it occurs by diffusion across the membrane

Answer 2

Movement of substance in and out of the cells takes place through a process called diffusion.

Explanation:

Like human body utilizes the required content and excretes the unwanted content, plant also does the same process through method called diffusion. Mostly the content which enters in and out of the plant cell includes water, carbon-di-oxide and oxygen.  

The plasma membrane of the cell acts as selective permeable membrane through which the diffusion of the substances takes place.
