Cell structure involved his photosynthesis and respiration.
I assume you are talking about plants.
Since this is not my area of expertise, I searched Google under the key words "photosynthesis and respiration" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.
The cell structures involved in photosynthesis and respiration are the chloroplasts and mitochondria, respectively.
1. Chloroplasts: Chloroplasts are membrane-bound organelles found in plant cells. They are responsible for carrying out photosynthesis, the process by which plants convert sunlight into chemical energy (glucose) to fuel their activities. Within the chloroplasts, there are several key structures involved in photosynthesis:
- Thylakoid Membranes: These are flattened, sac-like structures arranged in stacks called grana. Thylakoid membranes contain the pigments that capture sunlight, such as chlorophyll, and various enzymes involved in light-dependent reactions.
- Stroma: The stroma is the fluid-filled space surrounding the thylakoid membranes. It contains enzymes that drive the light-independent reactions of photosynthesis, also known as the Calvin cycle. These reactions use the energy stored in ATP and NADPH (produced during the light-dependent reactions) to convert carbon dioxide into glucose.
2. Mitochondria: Mitochondria are another membrane-bound organelle found in most eukaryotic cells, including plant and animal cells. They are responsible for carrying out cellular respiration, the process by which cells convert glucose and oxygen into ATP (adenosine triphosphate), the main energy currency of cells. Several structures within the mitochondria are involved in respiration:
- Outer and Inner Membrane: The mitochondria have a double membrane structure. The outer membrane acts as a protective barrier, while the inner membrane contains numerous folds called cristae, which increase the surface area available for chemical reactions.
- Matrix: The matrix is the innermost compartment of the mitochondria, enclosed by the inner membrane. It contains enzymes involved in the Krebs cycle (also known as the citric acid cycle or TCA cycle) and the electron transport chain. These processes generate ATP by breaking down glucose and utilizing the high-energy electrons harvested during oxidation.
In summary, chloroplasts are involved in photosynthesis and contain thylakoid membranes and stroma, while mitochondria are involved in respiration and contain outer and inner membranes with cristae, as well as a matrix.
