How are erythrocytes specialised to carry oxygen

  • Biconcave shape provides large SA for gas exchange

  • Enucleated more room for haemoglobin

  • Small about 7µm and flexible allows them to go along narrow capillaries

New cards

How are neutrophils specialised to defend against disease

  • Many lysosomes to ingest invading microbes

  • Well developed cytoskeleton to move lysosomes to vesicles

  • Many mitochondria provide energy for phagocytosis

  • Well developed Golgi

  • Lots of receptors on cell membrane to recognise foreign cells

  • Flexible shape to help engulf pathogens

How are epithelial cells specialised for absorption of food into blood

  • Microvilli increase SA for absorption of food

  • Many mitochondria provide energy for active transport

  • Many RER for protein synthesis (enzymes)

  • Folded basal membrane increases SA

  • Tight junctions join neighbouring cells together

New cards

How are epithelial cells specialised in moving dust from lungs

  • Cilia beat rhythmically to move dirt and dust

  • Many mitochondria provide energy for beating cilia

  • Goblet cells secrete mucus which traps dust


5
New cards

How are sperm cells specialised for fertilisation of egg

  • Flagellum to swim

  • Many mitochondria to provide energy through respiration

  • Haploid (23)

  • Acrosome contains digestive enzymes to penetrate egg


6
New cards

How are palisade cells specialised for photosynthesis

  • Many chloroplasts to absorb sunlight

  • Thin walls to allow short diffusion path for CO2

  • Positioned in upper part of leaf


7
New cards

How are root cells specialised for the uptake of mineral ions and water

  • Large SA to maximise diffusion of water and ions

  • Thin cell walls so ions and water can enter cell easily

  • Numerous mitochondria provide energy for active transport


8
New cards

How are guard cells specialised for lining the stomata of leaves

  • Open and close stomata

  • Vacuole to uptake water and become turgid

  • Chloroplasts to synthesise sugar to become turgid

  • Cellulose hoops only allow for cell to extend lengthways

  • Inner wall is thicker and less flexible than outer wall forcing cells to bend bean shaped and become turgid so open stomata
