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 organelles are found in chloroplasts?
A chloroplast is a type of organelle known as a plastid, characterized by its two membranes and a high concentration of chlorophyll. Other plastid types, such as the leucoplast and the chromoplast, contain little chlorophyll and do not carry out photosynthesis.
Who discovered the chloroplast?
Chloroplasts are the organelles that help with the photosynthesis in which the photosynthetic pigment is the chlorophyll that captures the energy from the sunlight. Complete answer: Julius Von Sachs discovered chloroplast involvement in photosynthesis.
What are the major functions of the chloroplast?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids.
What is the best definition of chloroplast?
Definition of chloroplast : a plastid that contains chlorophyll and is the site of photosynthesis — see cell illustration.
What is chlorophyll chloroplast?
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).
Why chloroplast is the most important organelle?
Chloroplasts play an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms.
What is special about chloroplast?
Chloroplasts are unique structures found in plant cells that specialize in converting sunlight into energy that plants can use. This process is called photosynthesis. Chloroplasts are considered organelles in plant cells.
What is chloroplast made of?
Chloroplasts consist of the outer and inner boundary membrane, a plasmatic matrix (stroma), and an internal membrane system (thylakoid). They contain cyclic DNA and ribosomes similar to those of prokaryotes.
How does a chloroplast work?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
What is the function and structure of chloroplast?
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 (O2) by photolysis of water. Produces ATP – Adenosine triphosphate by the process of photosynthesis.
