explain why chloroplasts are found only in plants cells ?
Answers
Answer:
Chloroplast is specific to plant cell because plants are the autotrophs which can prepare their food by conversion of light energy to chemical energy. It is the vital photosynthetic pigment in leaves as it involves the conversion of light energy into chemical energy.
Answer:
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
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.
Chloroplasts are one of the many unique organelles in the body, and are generally considered to have originated as endosymbiotic cyanobacteria.
In this respect they are similar to mitochondria, but are found only in plants and protista.
Both organelles are surrounded by a double celled composite membrane with an intermembrane space; both have their own DNA and are involved in energy metabolism; and both have reticulations, or many infoldings, filling their inner spaces.
Explanation:
Chloroplasts are found only in plant cells
Chloroplast is specific to plant cell because plants are the autotrophs which can prepare their food by conversion of light energy to chemical energy. It is the vital photosynthetic pigment in leaves as it involves the conversion of light energy into chemical energy. It absorbs all the radiations of variant colours like violet, blue, orange and red. But, it reflects the green light and hence the leaves appear green in colour. It absorbs the solar energy varying from the wavelength around 430nm (blue) to 662nm (red). Other than plants these are also present in some other organisms like bacteria and green algae.
