Cell chloroplast.

10.2: The structure of the chloroplast. In plants, photosynthesis takes place primarily in leaves, which consist of many layers of cells and have differentiated top and bottom sides. The process of photosynthesis occurs not on the surface layers of the leaf, but rather in a middle layer called the mesophyll ( Figure 10.2.1 10.2. 1 ). Jan 16, 2023 · A cell organelle that creates energy through photosynthesis is the chloroplast, which is exclusively present in algal and plant cells.

Jul 11, 2023 · Martin Jonikas. Chloroplasts are a specialized structure found inside the cells of land plants and red and green algae. Through the process of photosynthesis, chloroplasts convert sunlight and atmospheric carbon dioxide into the starches we eat and the oxygen we breathe. Despite their importance, we have only a fuzzy idea of how chloroplasts work. Chloroplast Definition. Chloroplast, found in plant cells and some protists such as algae and cyanobacteria, is a cell organelle known as a plastid. Chloroplasts are the food producers of the cell by converting light energy of the sun into sugar that can be used by the cell. This entire process is known as photosynthesis and it all depends on ...

Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast.

Round, green chloroplasts fill the middle of a plant cell. Image by Kristian Peters. Chloroplasts are tiny factories inside the cells of plants.Bacteria, mitochondria, and chloroplasts are similar in size. Bacteria also have DNA and ribosomes similar to those of mitochondria and chloroplasts. 4 ‍ Based on this and other evidence, scientists think host cells and bacteria formed endosymbiotic relationships long ago, when individual host cells took in aerobic (oxygen-using) and photosynthetic bacteria but did not destroy them.In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration. In animal cells, peroxisomes protect the cell from its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria.
