Specialised Cells

Question 1

How structure relates to function - Sperm Cell

Answer 1

• acrosome (head) contains enzyme to break into egg
  -tail to swim
• mitochondria for respiration to release energy
  -animal cell and eukaryotic

Question 2

How structure relates to function - Nerve Cell

Answer 2

• long to transmit electrical impulses over distance
  -animal cell and eukaryotic
• has a myelin sheath to insukate nerve cell so the electrical signal stays in nerve

Question 3

How structure relates to function - Muscle Cell

Answer 3

-contains protein fibres that can contract when energy is available, making the cell smaller
- animal cell and eukaryotic

Question 4

How structure relates to function - Root Hair Cell

Answer 4

• Long extension to increase surface area for water and mineral uptake
  -thin cell wall
  -plant cell and eukaryotic

Question 5

How structure relates to function - Xylem Cell

Answer 5

• waterproofed cell wall
  -cells are hollow to allow water to move through
• plant cell and eukaryotic

Question 6

How structure relates to function - Phloem Cell

Answer 6

• some cells have lots of mitochondria for active transport
  -some cells have little cytoplasm for sugars to move through easily
• plant cell and eukaryotic
• has sieve like tubes to aid in transport of food
