• Cell: the smallest unit of living things that can carry out the basic process of life.

Cells

• Unicellular: one-celled organism is made of a single cell that carries out its life process.

Cells

• Multicellular: Organisms made of more than one cell.

• What is inside of an Animal Cell?

• In your book there are 5 items you need to know!

Cells

• Cell membrane: layer around the outside of the cell that controls what materials move into and out of the cell.

Cells

• Cytoplasm: the gel-like liquid that fills the cell. The green fluid shown in the cell is the Cytoplasm.

Cells

• Nucleus: the control center of the cell. Usually found in the center of the cell, and is large and round.

Cells

• Mitochondria: Oval in shape and is the energy producer within a cell.

Cells

• Vacuoles: used to store food and water within a cell.

Plant Cells

• Plants have many of the same structures and organelles as animal cells. However, plant cells often have a box-like shape and are a bit larger than animal cells.

Plant Cells

• Cell Wall: Plants have an additional outer covering around the outside of the cell. The wall is a stiff structure and provides support for the plant.

Plant Cells

• Vacuole: Different from animal cells, plant cells usually have one large, central vacuole. In plant cells this vacuole stores water and provides extra support.

Plant Cells

• Chloroplast: Plants make their own food in structures inside these cells. Chloroplast is a green structure (which is one reason most plants are green) where sunlight is used to produce food for the plant.
