In single celled organisms, the cell grows larger and then divides, CREATING A NEW ORGANISM. In organisms composed of many cells, the organism GROWS BIGGER when it creates more cells.
The words I capitalized are the direct answers.
I'm sorry I got to your question so late. I hope that this helps!
The amoeba is eukaryotic cell while bacteria is prokaryotic
protists have a membrane-bounded nucleus, which bacterial cells lack.
this is because the protists actually have a nucleus, which is an area in the center of the cell with a membrane, and it is full of DNA. In the domains of eubacterian and archaebacteria, these do not have nuclei.
Cell division may be..... ya thatis reproduction asexual
The right answer is: controls the movement of substances into and out of cells.
This picture represents a plasma membrane.
The plasma membrane is the membrane that delimits a cell. It separates the cytoplasm from the outside environment.
Special proteins ensure the selective permeability of the membrane (pores), the recognition of chemical signals or carry markers (MHC antigens ...).
The pores are the doors of the membrane. They are macromolecular buildings of protein or glycoprotein nature, sometimes very complex. They are inserted in the bilayer and control exchanges between intracellular and extracellular (with receptors, carriers).
