2) The diagram refers to some structures found in cells. Which area in the diagram represents plant cells?
A plant cell has a large central vacuole, which stores the cell sap, many mitochondria to release energy for processes such as active transport and ribosomes for making protein.

8) The table applies to four cells.
which one is a xylem vessel?
Xylem tissues are plant cells modified to conduct water and mineral salts from the root to other parts of the plant. They are hollow tubes with no protoplasm so that water can flow continuously through them.

11) The table shows three functions of cells. Which row is correct ?
A root hair cell absorbs water and mineral salts . A xylem vessel has thick lignified cellulose walls to provide support. Red blood cell contains haemoglobin which absorbs oxygen and transports it as oxyhaemoglobin.
