Cells 1
Houses DNA and is the control center of the cell
What is the Nucleus?
Cell eating
What is Phagocytosis?
Condensed chromatin
What is Chromosomes?
Release of substances out of a cell.
What is Exocytosis?
Cell drinking
What is Pinocytosis?
Extend into the membrane/ Glycoproteins
What is Integral Proteins?
Span the width of the membrane
What is Transmembrane Protein?
Modifies and packages proteins. " Post office" of the cell
What is the Golgi Apparatus?
Separates the cell's internal environment from its external environment
What is Plasma membrane?
On the surface of the membrane
What is Peripheral protein?
Whip like tails found in one-celled organisms to aid in movement
What is Flagella?
Largest filaments that play a role in cell structure and movement. Cell division
What is Microtubule?
Long, thin fibers that function in the movement and support of the cell. Shape
What is Microfilaments?
Holes in the nuclear membrane allow passage of RNA, but no DNA
What is Nuclear Pores?
Inside nucleus/ site off ribosome synthesis
What is Nucleolus?
projections that increase the cell's surface area
What is Microvilli?
"Powerhouse" of the cell. Site of ATP synthesis.
What is the Mitochondria?
Hair like projections that extend from the plasma membrane and are used for moving substances
What is Cilia?
A solution in which the concentration of solutes is greater than that of the cell that resides in the solution. Movement of water out of cell.
What is Hypertonic Solution?
Threadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments. Reinforcement.
What is Intermediate Filaments?
A network of fibers that holds the cell together, helps the cell to keep it's shape, and aids in movement
What is Cytoskeleton?
A solution in which the concentration of solutes is essentially equal to that of the cell which resides in solution. No net movement of water.
What is Isotonic Solution?
Process by which a cell takes material into the cell by in folding of the cell membrane.
What is Endocytosis?
Makes Proteins
What is Ribosomes?
A solution in which the concentration of solutes is less than that of the cell that resides in the solution. Movement of water into the cell.
What is Hypotonic Solution?
