Parts of the Chloroplast

Hello everyone! 

Do you know an thing which has two membranes? What is it? 

Ans: Yes, it is the Chloroplast. The chloroplast will have 2 membranes.

Do you know where it is present?

Ans:  It will be present in the leaf of the plant. 

Before, we go deep inside the chloroplast functions, we will first have to need to learn about the parts and basics of the chloroplast. Today, we will learn about the parts of the Chloroplast.

Parts of the Chloroplast:

So, in this picture you can see the parts of the chloroplast.

Fuctions of the parts:

Inner Membrane - The inner membrane forms a border to the stroma. It regulates passage of materials in and out of the chloroplast. The Inner membrane is not permeable to small organic molecules.

Outer Membrane - The outer membrane is permeable to small organic molecules.

Inner Membrane space - The space between the Inner membrane and the outer membrane.

Thylakoid - The thylakoid is an internal system of interconnected membranes, that carry out the light reaction or photosynthesis.

Granum - Stacks of Thylakoid is known as Granum.

Lumen - What is present inside the Thylakoid is known as Lumen.

Facts:

• Half of the photosynthesis reaction will happen in the Lumen.

Stroma - Stroma is the fluid present in the Chloroplast

Lamella - Lamella is a tube like connection between two granums.
