Specialised cells

Question 1

what are specialised cells?

Answer 1

• cells that have special features that help them carry out a specific function

Question 2

what examples of specialised cells in animal cells

Answer 2

• muscle cells
• nerve cells
• red blood cells

Question 3

What are examples of specialised cells in plant cells?

Answer 3

• palisade cells
• root hair cell

Question 4

what are Muscle cells?

Answer 4

• specialised cells that contract and relax
• able to change their length - able to move through a full range of motion
• Long and stretching - helps contractions

Question 5

what are nerve cells?

Answer 5

• specialised cells that carry electrical impulses
• long with branches

Question 6

what are red blood cells?

Answer 6

• specialised cells that carry oxygen through the blood and bind to the haemoglobin
  -biconcave shape = increases surface area
• no nucleus

Question 7

what are palisade cells? (plant)

Answer 7

• specialised cells for photosynthesis
• vertical orientation = increases surface area
• the upper side of the leaf contains chloroplasts that help absorb light for photosynthesis

Question 8

what are root hair cells? (plant)

Answer 8

• specialised cells for absorption of water and minerals
• have large surface area = increase the rate of absorption
• hair-like structure = increases root surface area

Question 9

how do sperm cells get their energy?

Answer 9

the sperm cells get their energy from the mitochondria in the middle section of the sperm cells which transfer energy for the movement of the flagellum f (the tail)
