Answers
Answer:
Membrane Envelope
It comprises inner and outer lipid bilayer membranes. The inner membrane separates the stroma from the intermembrane space.
Intermembrane Space
The space between inner and outer membranes.
Thylakoid System
The system is suspended in the stroma. It is a collection of membranous sacs called thylakoids. The green coloured pigments called chlorophyll are found in the thylakoid membranes. It is the sight for the process of light-dependent reactions of the photosynthesis process. The thylakoids are arranged in stacks known as grana and each granum contains around 10-20 thylakoids.
Stroma
It is a colour less, alkaline, aqueous, protein-rich fluid present within the inner membrane of the chloroplast present surrounding the grana.
Grana
These are the sites of conversion of light energy into chemical energy.
It is a green photosynthetic pigment that helps in the process of photosynthesis.
Functions of Chloroplast
Following are the important chloroplast function:
The most important function of the chloroplast is to synthesize food by the process of photosynthesis.
Absorbs light energy and converts it into chemical energy.
Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and 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.
The carbon dioxide (CO2) obtained from the air is used to generate carbon and sugar during the Calvin Cycle or dark reaction of photosynthesis.
