Presentation transcript:

Made to fertilise an egg. Very small. Can swim to find the egg. The head has enzymes which can break through an egg cell in order to fertilise it. Has a large number of cells to make energy. It contains genes in the nucleus which carry genetic information from the father to help give the offspring its features. Sperm Cell

Egg Cell Large and bulky as it doesn’t need to move far. Contains a yolk that has a food store in it which helps a young organism develop when fertilisation has happened. It contains genes in the nucleus which carry genetic information from the mother to help give the offspring its features. Has a round shape allowing it to move easily through the fallopian tubes to the womb.

Palisade Cell Tall. Large surface area. Needed for photosynthesis (process where plants make food). Found on the top side of the leaf. Packed with chloroplasts which contain chlorophyll to absorb sunlight for photosynthesis.

Cilia Cell These cells line all air passages in your lungs and leading to your lungs. Help prevent lung disease. They have tiny hairs which help filter the air as it moves through. The airs sweep mucus, which traps the dust and dirt you breathe in, back up to the throat where it is swallowed.

Root Hair Cell Long. On the surface of a plant’s roots. Large surface area. Absorbs minerals and water from the soil for the plant. Really thin cells wall which make it easier for the water and minerals to pass into the roots so that they can be transported around the plant.

Red Blood Cells Round in shape. Thin outer membrane. Carry oxygen around the body in blood. Large surface area. No nucleus so there is more space to hold oxygen. Contains haemoglobin which combines with the oxygen to carry.
