Animal Cells and Plant Cells

Animal Cells and Plant Cells

• Differences and comparisons

2
Animal Cells

• Have smaller vacuoles
• No cell walls or chloroplasts
• Since no cell wall, it can be a variety of shapes

What is a cell wall?

• Cell walls are made of specialized sugars called

• Cellulose provides a protected framework for a
  plant cell to survive.
• Cell walls also help a plant keep its shape.

What are chloroplasts?

• Chloroplasts are the food producers of the plant
  cell.
• Chloroplasts use a process called photosynthesis.
  Photosynthesis is the process of a plant taking
  energy from the Sun and creating sugars.

Review

• There are two types of cells animal cells and
  plant cells.
• Only plant cells have cell walls and
  chloroplasts.
• Chloroplasts create the sugars in photosynthesis.
