A plant cell differs from an animal cell in the absence of?
Plasma Membrane
What makes up half the mass of a membrane?
The cell membrane plays host to a large amount of protein that is responsible for its various activities. The amount of protein differs between species and according to function, however the typical amount in a cell membrane is 50%.
What does membrane - bound sacks means?
When substances are too large to pass through the cell membrane directly (they'd leave a gaping hole), they are enclosed in a lipid sac that is similar in composition to the cell membrane. Instead of punching through the membrane, the sac merges with it allowing the large substance to exit the cell without damaging the membrane.
Does a prokaryotic cell have a cell membrace?
Yes.Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.But, prokaryotic cells do not have membranes around their organelles (inside the cell), whereas eukaryotic cells do.
What structure controls the passage of substances into and out of the cell?
cell membrane
A plant cell differs from an animal cell in the absence of?
Plasma Membrane
What regulates cytoplasm composition?
Central vacuole
How does the composition of a living cell affects its existence?
the composition of a cell by its nature affects its existence because cell is composed from different things like membrane,plasm, mitochondria etc...
What is membrane sidedness?
The cell membrane regulates the flow of materials in and out of the cell. Membrane sidedness is an important concept in cell biology because to gives a better understanding on how the cell membrane functions.
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
Does a human cell have a cell membrane?
A cell might lack a cell wall, but all cells do have cell membranes as it is a quite important composition of the cell, ensuring some basic functions.

Explain how osmosis differs from diffusion?
Osmosis differs from Diffusion because in osmosis only water moves, and during diffusion, small molecules move across the cell membrane.

What organelle separates cell interior from environment?
What seperates the internal composition and the Cytoplasme (the liquid inside the cell holding all parts or organisms of the cell in place) of the cell from the external is the plasmic membrane. This membrane has many functions as it's strcuture helps it to move or squeeze into places the cell needs to go.

Yes.Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.But, prokaryotic cells do not have membranes around their organelles (inside the cell), whereas eukaryotic cells do.
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
