Specialised Cells. Plants and animals are multicellular (consist of many cells). They contain many different types of cells. Each type of cell is designed to carry out a particular job or function. This is known as CELL SPECIALISM Not all cells look the same.

specialised cells
Specialised Cells
  • Plants and animals are multicellular(consist of many cells).
  • They contain many different types of cells.
  • Each type of cell is designed to carry out a particular job or function.
  • This is known as CELL SPECIALISM
  • Not all cells look the same.
  • Some cells have a special shape and features to help them do a certain job.
sperm cell
Sperm cell

Head contains enzymes & nucleus

  • The head contains enzymes which allow it to digest into an egg cell and join with it.
  • Designed to Fertilise eggs.
  • Found in the Testes

Tail

  • A sperm is small and has a long tail that provides movement so it can swim and find an egg cell.
egg ovum cell
Egg (Ovum) Cell
  • Designed to be Fertilised.
  • Found in the Ovaries.
  • An egg cell is large and bulky.
  • Contains yolk which provides a large food store for the new cell being formed.

Cytoplasm containing yolk

Layer of jelly

Nucleus

palisade cell
Palisade Cell
  • Designed for Photosynthesis
  • Found in the top of a leaf
  • Tall and has a large surface area to absorb water and minerals.
  • Packed with chloroplasts to help make plant food.

Nucleus

Chloroplasts

ciliated cell
Ciliated Cell
  • Designed to stop Lung Damage
  • They line all the air passages in the lungs.
  • They have tiny hairs called cilia.
  • Hairs sweep mucuswith trapped dust and bacteria back up the throat.

Nucleus

cilia

root hair cell
Root Hair Cell
  • Thin cell wall makes it easy for minerals to pass through.

Vacuole

  • Designed for absorbing.

thin cell wall

  • Has a large surface which helps it to absorb water and minerals.

Cell membrane

  • Found in a plant root.
nerve cell neurone
Nerve Cell (neurone)

Nucleus

  • They are long
  • They have connections at each end
  • Can carry electrical signals
  • Their job is to carry nerve impulses to different parts of the body.
red blood cell
Red Blood Cell
  • Designed to carry oxygen
  • Found in blood.
  • Large surface area, for oxygen to pass through.
  • Contains haemoglobin, which joins with oxygen.
  • Has no nucleus
questions
Questions
  • Why are nerve cells so long?
  • Where are egg cells found?
  • What is palisade cell specialised to do?
  • Why does a root hair cell have a thin wall?
  • The hairs in a ciliated cell are known as?
  • What is a sperm cell designed to do?
  • How are red blood cells different from other cells?
