There are chloroplasts present in every green plant and algal cell. They are the plants’ primary source of nutrition. These are situated in the guard cells of the plant’s leaves, which may be found in the plant. They have a high chlorophyll content, which enables them to absorb more of the sun’s rays. In animal cells, this particular organelle of the cell is absent.
Within the cells of the parenchyma that make up the leaf mesophyll, chloroplasts can be found in unusually high concentrations (the internal cell layers of a leaf).
What is chloroplast in plants?
A Bachelor of Science degree from Patna University (2020) Chloroplasts are a specific kind of cellular organelle that may be discovered in the cells of a plant’s leaves. The chloroplasts contain a green pigment called chlorophyll, which is responsible for absorbing sunlight and initiating the process of photosynthesis.
Where does photosynthesis take place in chloroplasts?
Chlorophyll, the pigment that gives plants their green color, is found in high concentration in the thylakoid membrane of chloroplasts, which is also where photosynthesis takes place. Depending on the kind of plant, the chloroplast can be found anywhere in the cytoplasm of the cells that make up the plant’s leaves as well as other plant components.
What type of chloroplasts are found in algae?
The majority of the chloroplasts that are portrayed in this article are of the green color. Plants and green algae both store their starch within chloroplasts, and in plants and some algae, the chloroplast thylakoids are stacked in grana-like arrangements.
What is the evolution of chloroplast?
Chloroplast ancestry and the process of evolution. Within a plant cell, chloroplasts are just one of many different kinds of organelles. It is believed that they arose from cyanobacteria through a process known as endosymbiosis, which occurred when a eukaryotic cell ingested a photosynthesizing cyanobacterium that went on to become a permanent resident of the cell.
