How are the specialised cells adapted Flashcards
How is the red blood vessel adapted
It has a biconcave shape which allows the blood vessel to travel through capillaries/ blood vessels without getting stuck. In the blood cells the blood contains haemoglobin which allows the organ to stick, the blood cells have a large surface area to carry more oxygen.
Egg cell adaptation
Has lots of mitochondria which carry out respiration to release energy
The nucleus contains half a set of genetics from the mother (contains nutrients for developing the embryo)
Sperm cell adaptation
Has a flagellum for swimming (long tail)
Has lots of mitochondria which carry out respiration to release energy
Nucleus contains half of the father’s genetics
Ciliated epithelial cell adaptation
Small thin hairs (cilia) which waft dust and bacteria up to your mouth faster
Small intestine cell adaptation
Has tiny folds called microvilli which increase the surface area for absorption of nutrients
Small finger like projection
These have a very good blood supply
Nerve cell adaptation
Has a long thin shape which makes it faster to send electrical impulses
Xylem cell adaptation
Consist of dead cells. They have a thick strengthened cell wall with hollow lumen. The have lignin which strengthens the walls the they can cope with the pressure and also makes them impermeable to water (cannot escape) Has no nucleus.
Palisade cell adaptation
Has chloroplasts. Photosynthesis happens within the chloroplasts of the palisade cell.
Has a tall thin shape.
Root hair cell adaptation
Has long thin hair extending from the cell. This allows it to have a larger surface area for absorbing water and nutrients from the soil. Has a very thin cell wall to make it easier for water to pass through the cell. Has a large vacuole for temporarily storing water that I have absorbed from the soil before it is transported up through the plant.
What does haemoglobin stick to
Oxygen
Practise drawing the cells
Yaaaa
