Animal, Plant & Bacteria Cells

Animal Cells

• Nucleus: Houses GENETIC MATERIAL (DNA) and controls cell activities.
• Cytoplasm: A gel-like substance where CHEMICAL REACTIONS occur.
• Cell Membrane: Controls what enters and exits the cell.
• Mitochondria: The site of AEROBIC RESPIRATION, which releases energy.
• Ribosomes: Where PROTEINS are synthesised.

Plant Cells

• Rigid Cell Wall: Composed of CELLULOSE and provides support and structure.
• Permanent Vacuole: Contains CELL SAP which is a storage for sugar and salts.
• Chloroplasts: The location of PHOTOSYNTHESIS. Contains CHLOROPHYLL to absorb light.

Comparing Plant and Animal Cells

• Animal Cells DO NOT have CELL WALLS or CHLOROPLASTS.
• They usually have SMALLER VACUOLES compared to plant cells.

Bacterial Cells: 

• Bacterial cells are PROKARYOTIC.
• They don’t have a true nucleus. Instead, they have a SINGLE CIRCULAR STRAND of DNA.
• Some have additional small rings of DNA called PLASMIDS.
