OrganellesParts of a

Cell

Plant Cell vs. Animal Cell• Plant cells have a cell wall,

but animal cells do not.

• Plant cells have chloroplasts, but animal cells do not.

• Plant cells generally have a more rectangular shape because the cell wall is more rigid. Animal cells have a round or irregular shape because they do not have a cell wall.

• Plants cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.

Organelles

• Parts of a cell

• Enables cells to live

Cell Membrane

• Thin layer that surrounds the cell.

• Controls what comes in and what goes out

• “Gateway” of the cell

Nucleus• Dark center of cell• contains DNA

• Controls the cell's growth and reproduction

• “Brain” of the cell.

Endoplasmic Reticulum (ER)• Zig- Zag Shape • ER is either

smooth or rough.• The ER carries

materials through the cell.

• “Post Office” of the cell

Ribosome• They are the

smallest organelle.• Float in cytoplasm

or stick to ER• Produce protein

(food)• “Kitchen” of the

cell

Mitochondria

• Bean-shape

• Burn sugar for fuel.

• “Powerhouse” of the cell.

Golgi Complex

• Looks like ER.• aka Golgi

Body/Apparatus• Ships protein

out of the cell.• “Fed X” of the

cell

Lysosomes• Destroy damaged

organelles.• Transport waste to

cell membrane for removal.

• Protects cell from invaders.

• “Trash man”

DNADouble Helix (spiral) inside the nucleus

Holds genetic material; passed from parent to child

Plants and Animal Cells

“Blueprints” for cell

Cytoplasm

• Clear, thick fluid

• Like jelly

• Supports and protects

organelles

Vacuole

• Fluid Filled bags

• Plant Cells only

• Stores water, food, and waste

Vesicle

• Membrane-covered compartments

• Storage• Form from ER

and Golgi bodies

Cytoskeleton

• Hollow tubes and long strings of fibers

• Inside cytoplasm

• Helps a cell keep its shape

• “Skeleton” of the cell

Chloroplast

• Green, oval shaped• Contains

chlorophyll• PLANTS ONLY• Takes energy from

sun and makes food for plants

Cell Wall

• Outer layer of plant cell only!

• Strong and stiff• Supports and

protects• “Support

system”
