Glycolate induces opening of stomata in

Options

A. presence of oxygen
B. low `CO_(2)` concentration
C. high `CO_(2)` concentration
D. absence of `CO_(2)`

Explanation

**Step-by-Step Solution:**

1. **Understanding Glycolate**: Glycolate is a compound that plays a role in the physiological processes of plants, particularly in the regulation of stomatal opening.

2. **Role of Stomata**: Stomata are small openings on the surfaces of leaves that allow for gas exchange. The opening and closing of stomata are crucial for photosynthesis and transpiration.

3. **Conditions for Stomatal Opening**: Stomata typically open in response to various environmental conditions, including light and the concentration of carbon dioxide (CO2) in the surrounding atmosphere.

4. **Glycolate and CO2 Concentration**: Glycolate is produced in the guard cells of stomata when the concentration of carbon dioxide is low. This low CO2 concentration is a signal for the plant to open its stomata to allow more CO2 to enter for photosynthesis.

5. **Energy Requirement**: The production of glycolate in guard cells provides the necessary energy for the opening of stomata. This energy is essential for the physiological changes that occur in the guard cells to facilitate stomatal opening.

6. **Conclusion**: Therefore, glycolate induces the opening of stomata specifically in conditions of low carbon dioxide concentration.

**Final Answer**: Glycolate induces the opening of stomata in low carbon dioxide concentration.
