Specialised cells

Question 1

What is the function of a xylem cell, and where is is found?

Answer 1

It transfers water minerals from the roots up to the leaves. It’s found in a plants.

Question 2

What is the function of a sperm cell and where is it found?

Answer 2

A sperm cell is found in a animal it fertilises and swims towards the egg.

Question 3

What are photosynthetic cells?

Answer 3

They contain chlorophyll that captures solar energy.With the help of Co2 it converts this into glucose.

Question 4

What are the function of photosynthetic cells?

Answer 4

Makes glucose for the plants.

Question 5

What Is the function of root hair cells?

Answer 5

Transfers water and minerals from the soil.

Question 6

What is the function of phloem cells?

Answer 6

Transports dissolved food in the plant.

Question 7

What is the function of muscle cells?

Answer 7

They contract to bring about movement.

Question 8

What is the function of a nerve cell (neuron)?

Answer 8

They carry out electrical impulses around the body .

Question 9

Name 4 specialised cells that can be found in a plant

Answer 9

specialised cells that are found in plants are xylem cells, phloem cells, root hair cells, and photosynthetic cells.

Question 10

Name 3 specialised cells that are found in animals?

Answer 10

specialised cells that are found in animals are sperm cells, muscle cells and nerve cells (neuron).

Question 11

Name 2 adaptations that are found in xylem cells?

Answer 11

1. Cells die inside and make long hollow tubes

2. lignin spirals and rings build up in the cell wall to make the cells strong.

Question 12

Name 3 adaptions that are found in sperm cells?

Answer 12

1. Long tail to move to the egg
2. large nucleus contains genetic information
3. Tip contains enzymes to break into the egg

Question 13

Name 1 adaption of a photosynthetic cell ?

Answer 13

1. usually found near the top of the leaf and the edge of the stem to receive solar radiation.

Question 14

Name 2 adaptation of a root hair cell?

Answer 14

1. large permanent vacuole that speeds up water movement

2. long finger like extension the gives a large surface area of absorption to happen.

Question 15

Name 2 adaptions of a phloem cell?

Answer 15

1. Wall between cells have sieve plates that let dissolved food through to the next cell
2. has companion cells with mitochondria to give sieve tubes energy to keep them alive.

Question 16

Name 3 adaptations for a muscles cell?

Answer 16

1. have many mitochondria to release energy for contraction
2. Store glycogen which can be broken down and used for respiration (energy)
3. Contain special proteins to contract

Question 17

Names 3 adaptations for a neuron?

Answer 17

1. Dendrites to make connection to other nerve cells
2. Long axon fiber to carry impulses
3. Nerve ending make neurotransmitters chemical to pass the impulses to other cells
