|
Cytoplasm
|
Open space between the nucleus and the cell membrane.
|
Provides excess space for free moving organelles.
|
|
|
Nuclear Envelope
|
Compose of two membranes, dotted with thousands of nuclear pores.
|
allows material to move into and out of the nucleus.
|
|
|
Nucleolus
|
Small, dense region in the center of the nucleus
|
Where the assembly of ribosomes begins.
|
|
|
Ribosomes
|
Small particles of RNA and protein.
|
Proteins are assembled on :
|
|
|
Endoplasmic Reticulum
|
An internal membrane system.
|
Is the site where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell.
|
|
|
Golgi apparatus
|
A stack of closely apposed membranes.
|
The function of the Golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell.
|
|
|
Lysomsomes
|
Small organelles filled with enzymes.
|
Digest, or breakdown, lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. Also involved in breaking down organelles that have outlived their usefulness.
|
|
|
Vacuoles
|
Saclike structure in cytoplasm. Can be big or small depending on cell type.
|
Stores materials such as water, salts, proteins, and carbohydrates
|
|
|
Mitochondria
|
Tube-like structures containing two membranes.
|
Organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use.
|
|
|
Chloroplasts
|
Round/tube-like structures with two membranes.
|
Organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis.
|
|
|
Cytoskeleton
|
A network of protein filaments.
|
Helps the cell to maintain its shape and also helps with movement.
|
|
|
Centrioles
|
Free floating structures.
|
Help with cell division.
