Cell partsThe nucleus acts as the control center for the cell. It coordinates, controls and manages cell functions.

Chromosomes are thread-like structures that carry genetic information. Chromosomes are found in the nucleus of every cell.
Genes are units of genetic information that determine the specific characteristics of an individual.

The cytoplasm is a jelly-like material that supports the nucleus and the other organelles. Also, nutrients are absorbed, transported and processed in the cytoplasm.

The nucleolus is the darker area found inside the nucleus.
Ribosomes build proteins that are necessary for cell growth and reproduction.

The endoplasmic reticulum is a series of canals that transports materials to different parts of the cell.
Mitochondria provides the cell with energy.

Centriole is a small protein structure critical for cell division. Vacuoles are fluid-filled storehouses that contain water, food, wastes and other materials.

Golgi bodies store proteins until they are needed by the cell.
Lysosomes are saclike structures that contain proteins that break down food and digest wastes and worn-out cell parts.

What makes a plant cell different from an
animal cell?
Jul 106:30 PM
Plant cells contain all the organelles found in animal cells plus a few other structures.
Cell Wall- surrounds the cell membrane. - composed of rigid material called cellulose. - protect and support plant cells.
Chloroplasts - organelle containing chlorophyll used in
photosynthesis.
Vacuoles - both animal and plant cells contain vacuoles, but in plant cells the vacuole is much LARGER.

Comparison of Plant and Animal Cells
Apr 1810:55 AM
The cell theory states:· All living organisms are made up of one or more cells.· Cells are the basic units in all living organisms.· All cells come from other cells.· The activity of an entire organism depends on the cells.
