Random specialised cells
Name one adaptation of an egg cell.
Yolk vesicles
Protective layer of cells
Half the DNA
•They are smaller than most other cells in the body. This allows them to get through tiny capillaries, so they can deliver oxygen to every part of the body.
What specialised cell is it?
Red Blood Cell
Found on the outside of plant roots. How do we call this specialised cell?
Root hair cell
Name three different organ systems.
Circulatory system
Respiratory system
Digestive system
Nervous system
Excretory system
Reproductive system
What name is given to the different parts of cells?
Organelles
The name of the hairs on the cells in the trachea that help to move dust and mucus away from the lungs.
Spell it.
Cilia
Carries electrical signals from one part of the body to another and they help all the different parts of the body to communicate with each other.
What specialised cell is it?
Nerve cell/ Neuron
What is the function of root hair cell?
Their function is to absorb (soak up) water from the soil.
A group of similar cells is called a ...............?
Tissue
How does oxygen move from the lungs to red blood cells
Diffusion
What part of a nerve cell spreads out to make connections to other nerve cells?
Dendrites
The cytoplasm in red blood cell contains a red pigment called ?
Haemoglobin
They are found in the leaves of plants.How do we call that specialised cell?
Palisade cell
An ................ is a structure made of many different tissues.
Define diffusion
Spreading of particles.

What adaptation do Root Hair cells have to assist them?
Large surface area.
Root hair extends through soil
They have tiny threads along one edge, like microscopic hairs. They can move. They sweep mucus to the back of the throat.
Which specialised cell is it?

Long and thin at top of leaf to absorb sunlight
A very long strand of cytoplasm in neuron. Electrical signals can travel along this very quickly. How do we call it?
Axon
WHat is the function of chlorophyll?
The chlorophyll absorbs energy from sunlight, which is used to help the plant make food.
