Specialised cells (B2.1)

Question 1

Root hair cell (1 functions and 2 adaptations)

Answer 1

Function: Absorbs water and dissolved mineral ions from the soil
- No organel (like chloroplasts) because its under soil
- Finger like extension to provide a large surface area to vol rationfor absorbtion to happen

Question 2

Sperm cell (1 function and 2 adaptations)

Answer 2

Function: sexual reproduction (male gamete)
- Long flagellum to travel to egg
- Lots of mitochondria

Question 3

Red blood cell (1 function and 3 adaptations)

Answer 3

Function: Transport exygen throughout the body in bloodstream
- Contains haemoglobin, red protein which transports O2
- No nucleus, increases space for O2 molecules
- Bioconcave shape –> large surface area to vol ratio for absorption to happen

Question 4

Palisade cell (1 function and 2 adaptations)

Answer 4

Function: Photosynthesis in leaves
- Contains many chloroplasts
- Tall box shape to absorb a lot of light passing through

Question 5

Muscle cell (1 function and 2 adaptations)

Answer 5

Function: contracts to allow movement of the body and organs
- contains lots of mitachondria for energy
- long and elastic to allow contraction and relaxation

Question 6

Nerve cell (1 function and 1 adaptation)

Answer 6

Function: conducting electrical impulses to different parts of the body
- the axon is long so it can conduct impulses for distant parts of the body

Question 7

Cilated cell (2 functions and 1 adaptation)

Answer 7

Function: moving mucus in the trachea and the bronchi of lungs + moves opum and zygote down the fallopian tube
- cilia –> hair like extensions of cell; they are constantly moving and sweep mucus

Question 8

Egg cell (1 function anf 1 adaptation)

Answer 8

Function: sexual reproduction (female gamete)
- ctyoplasm contains yolk; food store for the new individual to use in first stages of development

Question 9

White blood cell (1 function and 1 adaptation)

Answer 9

Function: engulfs and destroys pathogens; produces antibiodies
- flexible shape to squezze through blood vessels and engulfs microbes
