What is the cell structure involved in photosynthesis and respiration?

The cell structure involved in photosynthesis and respiration is the mitochondrion, which is responsible for carrying out both processes.

In photosynthesis, the starting materials are carbon dioxide (CO2) and water (H2O). The raw materials are sunlight and chlorophyll (a pigment found in plant cells). Chlorophyll captures sunlight energy and uses it to convert carbon dioxide and water into glucose (C6H12O6) and oxygen (O2).

In respiration, the starting material is glucose (C6H12O6) produced during photosynthesis. The raw materials are oxygen (O2) and glucose. Glucose and oxygen are used to release energy through a series of chemical reactions, producing carbon dioxide (CO2) and water (H2O) as byproducts.

The end product of photosynthesis is glucose (C6H12O6) and oxygen (O2), which are stored in the plant for energy use or released into the environment.

The end products of respiration are carbon dioxide (CO2) and water (H2O), which are released as waste products.

Regarding the energy requirement, photosynthesis requires energy from sunlight, which is absorbed by chlorophyll in the cells. This energy is used to drive the synthesis of glucose and the splitting of water molecules. Respiration, on the other hand, does not require external energy input like photosynthesis does. Instead, it releases energy by breaking down glucose molecules in a controlled series of reactions within the mitochondria. This released energy is then used by the cell for various functions.
