Question

A) What is the name of the process represented by the equation:

Carbon(IV) oxide + water -----> carbohydrate + oxygen gas
1. Photosynthesis
2. Respiration
3. Fermentation
4. Combustion

b) Give two conditions necessary for the process to take place:
1. Presence of sunlight
2. Availability of chlorophyll
3. High atmospheric pressure
4. Absence of oxygen

Answer 1

The equation represents the process of photosynthesis, where carbon dioxide and water are transformed into glucose and oxygen with the aid of sunlight. Necessary conditions for photosynthesis are the presence of sunlight and availability of chlorophyll.

Step-by-step explanation:

The process represented by the equation where carbon dioxide and water transform into carbohydrate and oxygen gas is known as photosynthesis. This is a critical chemical reaction that allows plants to utilize energy from sunlight to convert carbon dioxide and water into glucose (a simple sugar) and oxygen, which is a by-product. The general chemical equation for photosynthesis is 6CO₂ + 6H₂O + Energy → C₆H₁₂O₆ + 6O₂, indicating that six molecules of carbon dioxide and six molecules of water, using energy from sunlight, produce one molecule of glucose and six molecules of oxygen.

For photosynthesis to take place, two main conditions are necessary:

1. The presence of sunlight, as it provides the energy required for the photosynthesis reaction.
2. The availability of chlorophyll, which is the pigment within plant cells that absorbs sunlight and initiates the process of photosynthesis.
