1 - Cell Structure & cell transport
Animal cell - Mitochondria, chromosomes, cytoplasm, nucleus (eukaryotic, as they have a nucleus), cell membrane
Plant cell - cell wall, chloroplasts, cell wall, vacuole
Specialised cells - adapted for funciton
Root hair cell
Nerve cell
muscle cell
sperm cell
Palisade / photosynthetic cell
Xylem cell
Phloem cell
Animal cells
Plant cells
Bacterial cell
Slime capsule, flagellum, DNA (bacterial cells are prokaryotic, meaning they have no nucleus), plasmids
Microscopes
Light microscopes
Electron microscopes
Cell transport
Diffusion - high to low concentration e.g O2 moving into cell
Osmosis - Movement of water from a dilute (hypotonic) sol. to concentrated (hypertonic) sol. across a partially permeable membrane
Active transport - Low to high concentration; requires energy which is released in respiration.
