Year 7 Specialised Cells Quiz

What is the name of this specialised cell?

• Neuron

• Sperm Cell

• Root Hair Cell

• Red Blood Cell

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

• Transport oxygen around the body

• Carry the genetic material

• Absorb water and minerals from soil

• Transmit electrical impulses throughout the body

How is the structure of the neuron related to its function?

• It does not have a nucleus so it can carry more oxygen

• It has a projection that extends into the soil to give it a larger surface area

• It is long and thin to transmit electrical impulses over long distances

• It has a tail so it can swim to the egg

What is the function of the red blood cell?

• Carries the genetic material

• Carries oxygen around the body

• Transmits electrical impulses

• Absorb water and nutrients from the soil

Why is the red blood cell shaped like a donut without a hole in the middle?

• To give it a bigger surface area for carrying oxygen

• The haemoglobin makes it this shape

• So it is more efficient at carrying nerve impulses

• So it can photosynthesize more efficiently

Sperm cells need energy in order to swim to the egg cells. Which organelles are responsible for releasing the energy the sperm cells need?

• Ribosomes

• Nucleus

• Cell Membrane

• Mitochondria

How is a sperm cell adapted to burrow into an egg cell?

• It is long and thin

• It does not have a nucleus

• It has special chemicals called enzymes in the head.

• It contains chloroplasts with the green pigment chlorophyll

Leaf cells have a large surface area. Why is this important?

• To absorb lots of light energy for photosynthesis

• To hold more genetic information

• To allow them to transmit electrical impulses quickly

• So that they can carry more haemoglobin

Root hair cells do not contain chloroplasts. Why?

• Root hair cells do not contain chloroplasts because they do not release energy

• Root hair cells do not contain chloroplasts because they do not carry haemoglobin

• Root hair cells do not need chloroplasts because they do not photosynthesize.

• Red blood cells do not contain chloroplasts because they have their own genetic material

What is a specialized cell?

• A smaller structure within a cell, such as a nucleus or a ribosome

• A structure that contains all of the genetic information

• A type of cell that does not have a special role in the body

• A cell that has a changed shape and structure so that it can carry out a special role in the body
