Storage, clean up, and support

Vacuoles and vessicles Lysosomes Cytoskeleton

Vacuoles Store food,

water, or waste materials

Lysosomes Contain digestive

enzymes to digest unwanted particles

Cytoskeleton

Maintain cell shape Move materials within the cell

Microfilaments – support Microtublues – shape, movement

Cytoplasm Clear fluid within

cell that contains all organelles

Building proteins

Ribosomes Endoplasmic reticulum Golgi apparatus

Ribosomes

Makes proteins in the cell

May be free in cytoplasm or attached to ER

Endoplasmic Reticulum Series of folded

membranes that form sacs or tubes

Rough ER has ribosomes attached

Golgi apparatus

Saclike membranes used for storing/ packaging of chemicals

Capturing and releasing energy

Chloroplasts Mitochondria

Mitochondria

Energy center –ATP produced in cellular respiration

Chloroplast Only found in

plants/ algae Chloroplasts

contain the pigment chlorophyll

Cell boundaries

Cell membrane Cell wall

Cell Boundaries

Cell membrane – phospholipid bilayer

Controls what enters and leaves the cell

Cell Wall Found in plant cells Adds protection

and support.
