Definition of chloroplast in biology
What is a chloroplast easy definition?
A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.
What is chloroplast for class 10th?
“Chloroplast is an organelle that contains the photosynthetic pigment chlorophyll that captures sunlight and converts it into useful energy, thereby, releasing oxygen from water.
What’s in a chloroplast?
They are protected by a smooth outer membrane which holds all of its material. These plastids also contain the pigment chlorophyll. This pigment is what gives plants their green color. It’s this green color that distinguishes chloroplasts from other plastids or organelles in the plant cell.
What is chloroplast in Class 11?
CBSE Class 11 Biology: Chloroplast
“A chloroplast is an organelle in green plants and algae containing the photosynthetic pigment, known as chlorophyll, which absorbs sunlight and transforms it into usable energy, releasing oxygen from water.”
Who discovered chloroplast?
Hugo von Mohl
The first definitive description of a chloroplast was given by Hugo von Mohl in 1837 as discrete bodies within the green plant cell.
What is chloroplast with diagram?
Chloroplasts are a type of membrane-bound plastids that contain a network of membranes embedded into a liquid matrix and harbor the photosynthetic pigment called chlorophyll. It is this pigment that imparts a green color to plant parts and serves to capture light energy.
What are the 5 function of chloroplast?
Functions of Chloroplast
Absorption of light energy and conversion of it into biological energy. Production of NAPDH2 and evolution of oxygen through the process of photosys of water. Production of ATP by photophosphorylation. NADPH2 and ATP are the assimilatory powers of photosynthesis.
What is chloroplast and chlorophyll?
Chlorophyll: the pigment that gives plants their green color and allows them to absorb sunlight… Chloroplast: a part of a cell found in plants that converts light energy into energy plants can use (sugar). Other living organisms such as algae also have cells that contain chloroplasts.
What is difference between chlorophyll and chloroplast?
Mainly, chlorophyll absorbs red and blue light from the sun converting it into chemical energy but chloroplast is a part where photosynthesis takes place.

What is photosynthesis class 10th?
Photosynthesis is the conversion of sunlight, carbon dioxide (CO2), and water into food (sugars) and oxygen by plants, algae, and some microorganisms. Light energy is collected and used by green plants during the process to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
What is the function of a chloroplast?
Chloroplasts are the place for the major conversion of the sun’s radiation energy to chemical energy that is usable by organisms. Accordingly, they account for about 50% of the leaf protein [1], and the enzyme ribulose-1,5-bisphosphate carboxylase of chloroplast is by far the most abundant protein on the Earth [2].
What is chloroplast and chlorophyll?
Chlorophyll: the pigment that gives plants their green color and allows them to absorb sunlight… Chloroplast: a part of a cell found in plants that converts light energy into energy plants can use (sugar). Other living organisms such as algae also have cells that contain chloroplasts.
What is called photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is photosynthesis formula?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent. …
- Step 5-Light independent. …
- Step 6-Light independent. …
- calvin cycle.
Who discovered photosynthesis?
scientist Jan Ingenhousz
Dutch-born British physician and scientist Jan Ingenhousz is best known for the discovery of the process of photosynthesis, by which green plants in sunlight absorb carbon dioxide and release oxygen.
What is class 3 photosynthesis?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
