Question
Highlight two survival values of tropic response.
Answer
Tropic responses, also known as tropisms, are directional growth responses of plants in response to external stimuli such as light, gravity, or touch. These responses are adaptive behaviors that help plants optimize their growth and survival in their environment. Here are some examples of tropic responses and their survival values:
1. Phototropisms expose the leaves in position to maximize light absorption thereby enhancing photosynthesis.
2. Hydrotropism enables the roots of the plant to seek water important in biochemical processes in plants.
3. Haptotropism enables the plants obtain mechanical support, especially in those plants lacking woody stems.
4. Geotropism enables plants roots to grow deep into the soil thus offering firm anchorage.
5. Chemotropism enables the pollen tubes to grow towards the embryo sac thereby facilitating fertilization
