Give three ways in which animal cells are different from plant cells.
Plnt cells have a rigid cell wall, they have a permanent vacuole and they contain chloroplast.
1 of 12
Define diffusion.
Diffusion is the spreading out of particles from an area of high concentration to an area of low concentration.
2 of 12
What is the function of a red bood cell?
To carry oxygen.
3 of 12
Describe two ways in which the red blood cell is adapted to its function.
Concave shape gives the red blood cells a large surface area for absorbing oxygen/ concave shape helps the red blood cells pass through capillaries to body cells/ no nucleus maximises the space for haemoglobin.
4 of 12
Name the process by which cells become specialised for a particular job.
Differentiation.
5 of 12
What is an organ system?
An organ system is a group of organs working together to perform a particular function.
6 of 12
Name five organs that are part of the human digestive system.
Salivary glands/pancreas/liver/stomach/large intestine/small intestine.
7 of 12
The diagram shows a palisade cell from a leaf. Which label points to a chloroplast?
C
8 of 12
Name the green substance present in chloroplasts.
Chlorophyll.
9 of 12
Apart from having chloroplasts, suggest one other way in which a palisade cell is adapted for photosynthesis.
It has a tall shape/a large surface area for absorbing carbon dioxide.
10 of 12
The three diagrams are showing cells surrounded by glucose. Into which cell, A,B or C, will there be a net movement of glucose? Explain your answer.
B-it has a higher concentration of glucose outside the cell than inside, so glucose will diffuse into the cell.
11 of 12
Other than glucose, name one molecule that can diffuse through cell membranes into cells.
Oxygen.
