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
