- B2.1 Cells, Tissues and Organs
- Animal and Plant Cells
- Animal Cell
- Mitochondria - site of respiration which releases energy
- Ribosomes - where protein synthesis takes place
- Nucleus - controls the activities of the cell and contains genetic information
- Cytoplasm - site of most of the cell's chemical reactions
- Cell Membrane - controls the passage of substances into and out of the cell
- Plant Cell
- Cell Membrane
- Ribosomes
- Permanent Vacuole - important in keeping the cell rigid
- Mitochondria
- Cytoplasm
- Chloroplasts - site of Photosynthesis (contains chlorophyll)
- Cell Wall - gives strength and support
- Nucleus
- Animal Cell
- Diffusion
- Substances that need to enter the cells
- Glucose
- Oxygen
- Substances that need to leave the cells
- Carbon Dioxide
- Secretes (Chemicals)
- Diffusion is the net movement of particles from an area oh high concentration to an area of low concentration
- Substances that need to enter the cells
- Tissues and Organs
- Human Tissues
- Muscular Tissue - contracts to bring about movement
- Glandular Tissue - contains secretory cells that can produce enzymes or hormones
- Epithelial Tissue - covers the body
- Plant Tissues
- Epidermal Tissue - covers the surface of plants
- Mesophyll Tissue - contains lots of chloroplasts for photosynthesis
- Xylem and Phloem - transport materials in plants
- Human Tissues
- Animal and Plant Cells
