Animal and plant cells

• All living things are made of cells.

• Some living things (like bacteria) are made of just one cell, while others (like plants and animals) are made of many cells. 

• Plant cells have a more regular structure than animal cells, allowing them to fit together tightly like bricks. 

Animal cells

• Most animal cells have the following parts:

• Nucleus: Controls the cell's activities and contains genetic material.

• Cell membrane: Controls what enters and exits the cell.

• Cytoplasm: A jelly-like substance where chemical reactions take place.

• Mitochondria: The site of respiration, which releases energy for the organism.

Plant cells

• Plant cells contain all the same parts as an animal cell but also contain:

• Cell wall: A rigid structure made of cellulose that provides support and strength.

• Vacuole: Contains cell sap, a watery fluid that keeps the cell firm.

• Chloroplasts: The site of photosynthesis, which uses sunlight to produce energy.
