Cell Specialisation

Question 1

Name 2 examples of specialised cells (animal cells)

Answer 1

-Sperm cell
-Nerve cell
-Muscle cell

Question 2

Name 2 examples of specialised cells (plant cells)

Answer 2

-Root hair cell
-Xylem cell
-Phloem cell

Question 3

Name 2 adaptations of a sperm cell.

Answer 3

The midpiece is packed with mitochondria to provide energy for respiration.
The tail enables the sperm to swim.
The head of the sperm contains the genetic material for fertilisation

Question 4

Name the function of a xylem cell

Answer 4

To transport water and soluble minerals up from the roots of the plant.

Question 5

Name the function of the phloem cell

Answer 5

Moves sugar produced by photosynthesis to where it is needed for processes such as respiration and developing seeds.

Question 6

Name 2 adaptions of the root hair cells.

Answer 6

The root hair cell has a large surface area to provide contact with soil water.
It has thin walls so as not to restrict the movement of water.

Question 7

Name 1 adaptation of a xylem cell

Answer 7

There are no top and bottom walls between xylem vessels, so there is a continuous column of water running through them.

Question 8

Name 1 adaptation of a phloem cell

Answer 8

Companion cells provide energy required to transport substances in the phloem.

Question 9

Name 2 adaptations of a nerve cell

Answer 9

The nerve cell is extended, so that nerves can run to and from different parts of the body to the central nervous system.
he cell has extensions and branches, so that it can communicate with other nerve cells

Question 10

Name 1 adaptations of a muscle cell

Answer 10

They contain lots of mitochondria to provide the energy for muscle contraction.
