Graham's Bio Final Project! - Organelles

Present in all cell types
Regulates what enters and leaves the cell
Separates internal from external enviorment
Composed of a lipid bilayer

ONLY in plant cells
Surrounds the cell membrane
Helps protect and support the cell

Fluid filled area between the nucleus and cell membrane
Filled with organelles
"Cyto" = cell, "plasm" = fluid
Cytosol = cell fluid only

In eukaryotic cells
The control center of a cell, and contains DNA
Double layer membrane called the nuclear envelope
Covered with many small pores
Nucleolus synthesizes (makes) ribosomes, which are important in making proteins

Extension of the nuclear membrane
Regions with ribosomes = Rough ER (transport ribosomes)
Regions w/o ribosomes = Smooth ER (lipid synthesis)

Sites of protein synthesis

Sorts, chemically alters, and packages important molecule

The powerhouse of the cell
Generates fuel for cell's activities
Sites of cellular respiration

Responsible for intracellular digestion
Lysosomes are membranous sacs of acidic enzymes
Rare in plant cells

Powerhouse of the plant cell
Chlorophyl pigment gives plants their color
Site for photosynthesis

Detoxify harmful substances that enter the body

Stores extra material for the cell
- Nutrients, water, etc
Plants have a large central vacuole
Animals have smaller vacuoles

Helps support cell structure and drive cell movement
- Cilia - short hair-like extensions on the cell that aid in cell movement
- Flagella - long hair-like extensions on the cell that helps the cell propel
