Apr 27, 2017 · 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”.
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.

Jan 29, 2024 · A chloroplast’s structure is complex, comprising several distinct components: Outer Membrane: The outer membrane is a semi-permeable barrier that encases the organelle. Inner Membrane: The inner membrane is located just inside the outer membrane.
Jul 15, 2020 · What is chloroplast and what does it do in plant cell – learn its location, parts, structure & functions of the organelle in biology described with labeled picture.
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).
Sep 19, 2024 · In plants, chloroplast-containing cells exist in the mesophyll. Chloroplasts are surrounded by a double membrane similar to the double membrane found within a mitochondrion. Within the chloroplast is a third membrane that forms stacked, disc-shaped structures called thylakoids.
