Learning outcome – to understand the difference between plant and
animal cells and to learn about the different cells
and there functions.
All living organisms are made up of cells. Cells are the building blocks of life.
Because there are a vast number of cells, some cells are specialized to
ensure they provide a specific function.
Never call the nucleus the “brain of the cell”, it is not a very good description
and will not get you any marks.
Learn the difference between animal and plant cells, as it is a very common
|Red Blood cell||To carry oxygen in the blood.||Has hemoglobin which carries the oxygenHas a concave, donut like shapeDoes not have a nucleus so it can carry more oxygenHas a large surface area to allow to carry more oxygen|
|Nerve Cell||Carries nerve impulses (messages) from the body to the brain and back again.||They are long, have many connections so can reach every corner of the bodyThey carry electrical signals so the impulse is relayed quickly|
|Egg cell||To join with the sperm cell and provide nutrition for the zygote (new cell) when formed.||It is large and contains lots of cytoplasm for reaction to take place.|
|Sperm Cell||To reach the egg cell and join.||Has a tail, which allows it to move.Also has a head to carry genetic information and penetrate the egg cell.|
|Root Hair Cell||To absorb water and minerals.||Has a large surface area, which allows it to absorb as much as possible.|
|Palisade cell (Leaf cell)||To absorb sunlight to allow the plant to photosynthesize.||Has a large surface area and many chloroplasts, which allow it to absorb as much sunlight as possible.|
