Tissue in the human body is made up of millions of cell. Each cell is composed on mostly water along with various proteins, fats, and other stored material.
What are the similarities between a prokarytic cell and a eukaryotic cell?
They both: - contain genetic material (DNA/RNA) - are enclosed in a cell membrane - composed of the same basic chemicals (eg. proteins, nucleic acids) - have ribosomes
Most cell membranes are composed principally of?
proteins and lipids
What is a cell wall make of?
It is composed of cellulose fiber, polysaccharides, and proteins.
What surrounds nucleoli and chromatin?
Nucleoli are regions within the nucleus of a cell that are composed of proteins and RNA. They are surrounded by chromatin, which is the complex of DNA and proteins that make up chromosomes. Chromatin forms the structural basis for the nucleus and contains the genetic material of the cell.
What structure composed mainly of proteins and lipids aids in maintain homeostasis in a cell?
cell membrane
What material is cell wall chiefly composed of?
HEMICELLULOSE
What is the phYSICAL parts of cell membrain?
The cell membrane is composed of a phospholipid bilayer and proteins, which are embedded in the bilayer.
What is the material that composes the cell membrane?
The cell membrane is composed of phospholipids. They form a bilayer for the cell.
How does an active virus multiply?
Once inside a cell, a virus's genetic material takes over of the cell's functions. It instructs the cell to produce the virus's proteins and genetic material. These proteins and genetic material then assemble into new viruses.
Protective layer around all cell?
Cell membrane, it is composed of a lipid bilayer with various embedded proteins.
A stiff layer of nonmoving material that surrounds a plant cell?
The cell wall which is composed of cellulose
