Question 9
FThe figure shows a young plant. Three regions of the plant are labelled P, Q and R.
Figure: A young plant, with three regions labelled
a.[1]
Cells in region P are unspecialised. Cells in region Q are specialised.
Give one way in which an unspecialised cell is different from a specialised cell.
b.[1]
Cells in region R divide and then differentiate. Name one specialised cell that these cells could become.
c.[2]
A gardener cuts a piece from the stem of this plant and plants it in soil. The piece of stem grows roots and becomes a new plant.
Explain how the piece of stem is able to grow roots.
d.[2]
An animal eats all of the leaves from this plant. The plant is able to grow new leaves.
Explain how the ability of many plant cells to differentiate throughout life helps the plant to survive being eaten.
