Loading... Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and is used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O 2 ) by photolysis of water.
- In all green plants, photosynthesis takes place within the thylakoid membrane of the Chloroplast.
- Chloroplasts are cell organelles present only in a plant cell and it includes: Stroma Inner membrane Outer membrane Thylakoid membrane Intermembran...
- The most important function of chloroplast is the production of food by the process of photosynthesis.
- Chloroplast contains a green pigment called chlorophyll which gives it a green colour.
- There are three types of plastids-chloroplast, chromoplast and leucoplast.
- The stack of lamellae or thylakoids inside a plastid is called grana.

The chloroplast, found only in algal and plant cells, is a cell organelle that produces energy through photosynthesis. The word chloroplast comes from the Greek words khloros, meaning “green”, and plastes, meaning “formed”. It has a high concentration of chlorophyll, the molecule that captures light energy, and this gives many plants and algae a gr...
Chloroplasts are the part of plant and algal cells that carry out photosynthesis, the process of converting light energy to energy stored in the form of sugar and other organic molecules that the plant or alga uses as food. Photosynthesis has two stages. In the first stage, the light-dependent reactions occur. These reactions capture sunlight throu...
Chloroplasts, like mitochondria, are oval-shaped and have two membranes: an outer membrane, which forms the external surface of the chloroplast, and an inner membrane that lies just beneath. Between the outer and inner membrane is a thin intermembrane space about 10-20 nanometers wide. The space within the inner membrane is called the stroma. While...
Chloroplasts are thought to have become a part of certain eukaryotic cells in much the same way as mitochondria were incorporated into all eukaryotic cells: by existing as free-living cyanobacteria that had a symbiotic relationship with a cell, making energy for the cell in return for a safe place to live, and eventually evolving into a form that c...
Thylakoid– Flattened disks within the stroma of the chloroplast that contain chlorophyll and carotenoids, and perform photosynthesis.Photosynthesis– The conversion of light energy into chemical energy in the form of organic molecules.Symbiotic relationship– A close biological interaction between two different species.Algae– A large group of photosynthetic organisms including seaweeds, giant kelp, and diatoms.1. What is a difference between mitochondria and chloroplasts? A. Chloroplasts have an outer and inner membrane, while mitochondria do not. B. Chloroplasts are thought to have evolved from bacteria, while mitochondria are not. C. Photosynthesis occurs in chloroplasts, but not in mitochondria. D.Mitochondria have their own DNA; chloroplasts do not c...

Nov 1, 2023 · Functions of Chloroplasts. Chloroplasts are the sites for photosynthesis, which comprises a set of light-dependent and light-independent reactions to harness solar energy and convert it into chemical energy. The components of chloroplast participate in several regulatory functions of the cell as well as in photorespiration.
In eukaryotes, photosynthesis takes place inside an organelle called a chloroplast. Some prokaryotes can perform photosynthesis, but they do not contain chloroplasts (or other membrane-bound organelles). In plants, chloroplast-containing cells exist in the mesophyll.
One of the main functions of the chloroplast is its role in photosynthesis, the process by which light is transformed into chemical energy, to subsequently produce food in the form of sugars. Water(H2O) and carbon dioxide(CO2) are used in photosynthesis, and sugar and oxygen(O2) is made, using light energy.
