GCSE AQA Biology Plant Tissues, Organs & Systems: Plants and animals have many def

Question

Plants and animals have many defence responses.

Table 5 shows some plant defences.

Identify whether each defence is a chemical response or a physical response.
Tick (✓) one box in each row.

Table 5

| Plant defence                          | Type of response  |
|----------------------------------------|--------------------|
| Thick, waxy layer on leaf surface      | Chemical / Physical |
| Berries that are poisonous             | Chemical / Physical |
| Bark on trees that falls off           | Chemical / Physical |

Mimicry is a mechanical adaptation seen in both plants and animals.

Figure 5 shows two insects.

Hornet             Hornet Moth

Hornets are insects that sting other animals and cause pain.
Hornet moths do not sting other animals.

Suggest how mimicry helps the hornet moth survive.

The larvae of the hornet moth:

- live inside the roots of trees
- use the tree roots as a source of food
- cause damage to the tree roots.

Explain why a tree might die if the roots of the tree are damaged.
