Plant and Animal Cells — O/L Science

What must I remember about Plant and Animal Cells?

• All living things made of cells (cell theory)
• Animal cell: nucleus, cytoplasm, mitochondria, cell membrane
• Plant cell: all animal parts + cell wall, chloroplasts, large vacuole
• Prokaryotes (bacteria): no membrane-bound nucleus; smaller
• Diffusion: particles move high → low concentration (passive)

Test yourself (1 minute)

1. Cell membrane

   selectively permeable; controls entry/exit

2. Plant extras

   cell wall (rigidity), chloroplasts (photosynthesis), central vacuole

3. Osmosis

   water movement from high → low water potential across semi-permeable membrane

Must know

• Mitosis: 2 identical diploid daughter cells (growth/repair)
• Meiosis: 4 haploid gametes (reproduction/variation)
