1. Bindweed grows around other plants like rose bushes to get support and access to light and water. When the stem of bindweed was cut, the part above the cut died because it was cut off from water and minerals transported through the stem. 2. The document contains questions about a plant cell diagram, an investigation on the effect of sugar on pollen grain growth, the process of photosynthesis, an investigation on growing lettuce plants under different conditions, and issues with a potted plant not getting enough minerals. 3. An investigation from almost 200 years ago studied the growth of grass plants in small plots that either contained a single grass species or multiple grass species. It found that plots with multiple species produced

9. 6 Joe bought a potted plant. He kept it well watered but some of the leaves turned yellow.
Joe thought that the plant did not have enough light for photosynthesis.
He moved the plant closer to the window but more leaves turned yellow.
a He then thought the plant did not have enough minerals.
The table below gives information about minerals.
(i) Joe ’s plant did not have enough of one of the minerals in the table.
Use the information in the table to suggest which mineral this was.
_______________________________
[1]
(ii) A plant growing in a pot is more likely to be affected by a shortage (lack) of minerals
than a plant growing in a garden.
Give the reason for this.
