Question

Complete the following table:

	Mitochondria	Chloroplast
An energy organelle of cells:
Contains its own DNA:		yes
Converts CO2 & H2O into carbohydrates:
Converts carbohydrates into ATP energy for the cell:
Surrounded by a double phospholipid membrane:

Answer 1

Ans 1) An energy organelle of cells -> Only mitochondria

(Mitochondrion is referred to as powerhouse of the cell.Oxidative phosphorylation occurs in the mitochondrion and through ATP synthase, ATP synthesis occurs)

Ans 2) Contain its own DNA --> Both mitochondria and Chloroplast

Ans 3) Converts CO2 and H2O into carbohydrates --> Only chloroplast

(Photosynthesis occurs inside the chloroplast.In photosynthesis, carbohydrate (glucose) is produced from simple inorganic molecules like CO2 and H2O in the presence of light and chlorophyll).

Ans 4) Convert carbohydrates into ATP energy for the cell --> Only mitochrondria

(As discussed above, inside the mitochondrion oxidative phosphorylation occurs during which the ATP synthesis occurs).

Ans 5) Surrounded by a double phospholipid membrane --> Both mitochondria and chloroplast

(Both the mitochondrion and chloroplasts are surrounded by double layered membrane).
