Cholodny-Went theory is connected with

Options

A. phototropism
B. Photomorphogenesis
C. Photorespiration
D. Photosynthesis

Answer

**Step-by-Step Solution:**

1. **Understanding Cholodny-Went Theory**: The Cholodny-Went theory is a scientific explanation that describes how plants grow towards light, a phenomenon known as phototropism.

2. **Identifying the Key Component**: The theory focuses on the role of a plant hormone called auxin, which is crucial for plant growth and response to light.

3. **Mechanism of Action**: According to the Cholodny-Went theory, auxin is synthesized in the tip of the plant (the coleoptile tip in grasses). When light shines on one side of the plant, auxin is redistributed to the shaded side.

4. **Resulting Growth Response**: The higher concentration of auxin on the shaded side causes the cells there to elongate more than those on the light-exposed side. This differential growth results in the bending of the plant towards the light source.

5. **Conclusion**: Therefore, the Cholodny-Went theory is primarily connected with phototropism, as it explains how plants orient themselves in response to light.

**Final Answer**: The Cholodny-Went theory is connected with phototropism.
