Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,
and exocytosis).
Passive Transport
The cell membrane is the outer boundary of animal cells and plant cells, but plant cells also have a cell wall to protect their cells. The cell membrane and cell walls are the outer boundaries of cells.
No, cell division technically decreases cell volume. Cells aren't happy if the cytosol to cell membrane ratio is out of whack--as would occur if a cell were to grow too big. Many important cell processes are tethered to the membrane, and many reactions that occur in the cytosol require input signals from membrane-anchored proteins.
The cell membrane holds a cell together.
we use acetocarmine to stain chtomosomes. stained chromosomes distinguish from the other organels and materials, it gives the chromosomes a red color. it enables that, during the cell cyle we can observe the nucleus, duplication of DNA, and movement.

Plasma membrane a.k.a. --- cell membrane
M for membrane I would suppose.
The cell membrane of a plant cell controls the movement of materials into and out of the cell, and therefore maintains homeostasis.
The plasma membrane selectively controls movement of materials into and out of the cell, and has receptors for hormones and enzymes. The generic term for these two processes is endocytosis (material moved into the cell) and exocytosis (movement of material out of the cell).
