What is the cell membrane?
Defines the cell by acting as a barrier
What does the cell membrane do?
Helps keep the cytoplasm inside and foreign substances outside.
What are the two types of endoplasmic reticulum?
Smooth and Rough
What does rough endoplasmic reticulum have?
Ribosomes on the outside
What is the endoplasmic reticulum?

Do mitochondria contain their own DNA?
Yes! it is separate from the nucleus.
List the 4 functions of the mitochondria
1. Cell energy, 2. Cell signaling, 3. Cellular differentiation, 4. Cell cycle/growth regulation
In what kind of cells are mitochondria numerous?
Eukaryotic Cells
How many membranes does the mitochondria have?
Inner and Outer
What does the inner membrane of mitochondria do?
encloses the matrix (that has mitochondrial DNA and ribosomes)
What are between the inner and outer membrane of mitochondria?
Cristae (folds)
What kind of respiration occurs in the mitochondria?
Aerobic
What is a centrosome?
Involved in mitosis/cell cycle, has a pair of centrioles surrounded by protein
What are centrioles?
Cylinder shaped structures near the nucleus used for division.
What does each cylinder centriole have?
Nine groups of three microtubules.
What is a lysosome?
Structure that digests proteins, lipids, and carbs.
What can the lysosome do?
Help transport undigested substances to membrane so it can be removed
What are Cilia?
Appendages extending from surface of cell (causes movement)
Difference between flagella and cilia
Flagella are longer, and cells usually only have one
What does the nucleus contain?
DNA, and chromosomes.
Do all eukaryotic cells have a nucleus?
Yes
What is the nucleus responsible for?
Passing genetic material between generations.
Name the 6 parts of nucleus
1. Nuclear Envelope, 2. Nucleoplasm, 3. Nucleolus, 4. Nuclear Pores, 5. Chromatin, 6. Ribosomes
What do chromosomes store?
Genetic information about the plant or animal
