Unit 4: Cell Organelles

Mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Smooth Endoplasmic Reticulum

An endomembrane system where lipids & carbs are synthesized, and toxic substances are broken down.

Rough Endoplasmic Reticulum

System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm

nucleus

contain DNA that is used to control the making of proteins. controls the cell's activities

Nucleolus

Found inside the nucleus and produces ribosomes

Lysosomes

cell organelle filled with enzymes needed to break down certain materials (such as waste & worn out cell parts) in the cell; only in animal cells

large central vacuole

found in plants, this organelle stores water for the cell

animal cell vacuole

store waste, ions, lipids; much smaller

centrioles

Cell organelle that aids in cell division in animal cells only

Ribosomes

site of protein synthesis

Cytoskeleton

A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement

Chloroplast

An organelle found in plant and algae cells where photosynthesis occurs

Cilia

The hairlike projections on the outside of cells that move in a wavelike manner and used in locomotion

Flagella

whiplike tails found in one-celled organisms to aid in movement
