What biochemical process takes place in the chloroplast?
What biochemical process takes place in the chloroplast?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
What chemical process is commonly associated with chloroplasts?
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
What is chloroplast with diagram?
Chloroplasts are found in all higher plants. There are two distinct regions present inside a chloroplast known as the grana and stroma. Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.
What are the steps of chloroplast?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
What is the main function of chloroplast in a plant cell?
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 are two main functions of chloroplasts?
The main role of chloroplasts is to conduct photosynthesis. They also carry out functions like fatty acid and amino acid synthesis.
Why do chloroplasts have a double membrane?
The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The prokaryotes are believed to have relinquished certain genes to the nuclei of their host cells, a process known as endosymbiotic gene transfer.
What is the structure and function of chloroplasts?
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 the function of chloroplasts?
What are two functions of chloroplasts?
Function of Chloroplasts They are responsible to carry out photosynthesis, the process of conversion of light energy into sugar and other organic molecules that are used by plants or algae as food. They also produce amino acids and lipid components that are necessary for chloroplast membrane production.
