A cell wall is a rigid structure, so I wonder how organisms with such a structure are able to take up nutrients from their environment?
If there is only a plasma membrane, vesicles can be formed which pinch off and thus take up nutrients from the environment and merge with other vesicles to form endosomes and later lysosomes. The other way transport is also possible, where waste products can be released by merging of a vesicle w/ the plasma membrane.
So what happens in plants or fungi?
