Specialised Cells

Question 1

Differentiation

Answer 1

The process by which a cell divides by mitosis into different specialised cells

Question 2

Specialised Cell

Answer 2

A cell with a particular structureor feature that allows it carry out a particular job more efficiently

Question 3

Stem Cell

Answer 3

Unspecialised cells that work by dividing mitosis into different differentiated cells which are specialised

Question 4

Specilaised cells e.g.

Answer 4

Epithelial cells
Red Blood Cells
Sperm Cells

Question 5

Epithelial Cells

Answer 5

Cell of the small intestine have more folds called microvilli. Increase the surface area of the cell membrane so that molecules can be absorbed more efficiently. they also have lots of mitochondria that release the energy for the active transport of substances across the membrane

Question 6

Red Blood Cells

Answer 6

These cells have no nucleus so there is more room for the oxygen carrying compound hemoglobin. this means more oxygen can be carried around the body

Question 7

Sperm Cells

Answer 7

These cells contain a lot of mitochondria to release large amounts of energy need to propel them towards an egg
