a. nucleus- controls cell function (has dna)
DESCRIPTION
Eukaryotic cells have a membrane bound nucleus that contains genetic information and directs activities of the cell. They also have membrane bound organelles. Ex.: Plants, Animals, Fungus , Algae. - PowerPoint PPT PresentationTRANSCRIPT
B. Eukaryotic cells have a membrane bound nucleus that contains genetic information and directs activities of the cell. They also have membrane bound organelles.
Ex.: Plants, Animals, Fungus, Algae
1. Eukaryotic cells have organelles- cell structures that perform specific functions. Animal cells have:
a. Nucleus- controls cell function (has DNA).
b. Nucleolus- inside nucleus- makes ribosomes.
b. Nucleolus- inside nucleus- makes ribosomes.
c. Endoplasmic Reticulum- Cellular chemical reactions and protein packaging.d. Ribosomes- synthesizes (makes) proteins.
d. Ribosomes- synthesizes (makes) proteins.
e. Golgi Apparatus- modifies proteins and other substances. It sorts, packages and transports them where they need to go (using vesicles).

f. Mitochondria- makes energy for the cell transforms glucose and other substances into ATP.

h. Vacuoles- storage compartments for waste or needed nutrients. In plants vacuoles are larger and store water.

2. All cells have a cell membrane- the phospholipid bilayer that regulates what moves into and out of the cell.

3. All cells have cytoplasm- the gelatinous fluid that suspends the organelles and a cytoskeleton, a framework of protein fibers that supports the cell.

Plant Cell vs. • Chloroplasts
For photosynthesis• Large vacoules• Cell Wall
For structural support
Animal Cells
• No chloroplasts
• Small vacuoles• No cell wall
