What is Chloroplast?
The chloroplast word originated from the Greek word “chloros”, meaning “green” and “plast”, meaning “form” or “entity”. All green plants and algae have chloroplasts inside their cells. They are the food producers of plants. They consist of a high concentration of chlorophyll that traps sunlight.
In higher plants, almost all chloroplasts are uniformly round, oval, flattened, or elliptical. Their length can be 2-5 µ or up to 100 µ while the width remains 3-4 µ. According to the personnel, their number should be up to 20-40 cans. Usually, their presence is close to the nucleus or cell wall. Chloroplast has its own extra-nuclear DNA and therefore is semiautonomous, like mitochondria. They also produce the lipids and proteins needed to make the chloroplast membrane.
Location of Chloroplast – Where are Chloroplast Found?
Chloroplasts are found in mesophyll cells, which are the green tissue of leaves. They are also present in other green parts of the plant, for example stems and unripe fruits. The chloroplasts in these cells are responsible for conducting photosynthesis. It is not found in animal cells; they are a unique feature of plant cells and some types of algae.

Chloroplasts: Diagram, Structure and Functions
The structure and function of chloroplast are adapted for photosynthesis. Chloroplast is an eukaryotic organelle found in plant cells and some algal cells which forms the site for photosynthesis. Chloroplasts contain the pigment chlorophyll, which captures light energy and uses it to synthesize organic compounds, including sugars, from carbon dioxide and water.
Chloroplasts give plants their green colour and are essential for their growth and survival. In this article, we will cover the structure and function of chloroplast, along with their diagram.
