Cell Organelles

Plasma or Cell Membrane:

a barrier which holds all of cell pieces

holds in fluids and organelles in a cell

present in both animal and plant cells

Cytoplasm:

made of polysacchrides

a shield or wall to protect a cell

cytoplasm is present in plant cells

Nuclear Membrane:

a double layered membrane surrounding the nucleus of eukaryotic cells

DNA in a cell being protected by a nuclear membrane

nuclear membrane is present in animal cells

Centrioles:

a ring or group of Microtubules

provides spinal tubes for the mitosis

centrioles is present in animal cells

Ribosomes:

grain-like bodies floating in the cytoplasm attached to the endoplasmic

produces protein

ribosomes are in both animal and plant cells

Endoplasmic Reticulum:

smooth throughout a cell but rough and look like pebbles

transport cellular material throughout a cell

endoplasmic reticulum is present in both plant and animal cells

Chloroplast:

green surrounded by inner and outer membranes in a cell

captures sunlight and uses it to produce food for a plant cell

Chloroplast is present in plant cells

Peroxisomes:

a single membrane that contains digestive enzymes for breaking down toxic materials in the cell

digesting fatty acids

peroxisomes is present in both animal and plant cells

Cytoskeleton:

a network of fibers composed of proteins contained within a cell's cytoplasm

provides an important structural framework for cells shapes

a cytoskeleton is in both animals and plant cells
