Answer:

Mitochondria and chloro plasts

Explanation:

Answer 2

Answer:

Two organelles that are double membrane-bound are i) Mitochondria ii) Chloroplasts

Characteristics of mitochondria

The mitochondrion is a double membrane-bound structure with the outer membrane and the inner membrane dividing its lumen distinctly into two aqueous compartments, i.e., the outer compartment and the inner compartment.

• Mitochondria is semi-autonomous as they possess their own DNA.

• Mitochondria is the place of aerobic respiration.

Characteristics of Chloroplasts

• They are found in plants and euglenoids, variously shaped in lower plants and disc-shaped in higher plants

• They have specific pigments which imparts colour to the leaves of the plants

• Chloroplasts possess their own DNA.

• Pigments help to trap sunlight thereby helps in photosynthesis.

• Consists of membrane-flattened sacs known as thylakoids located in their matrix. At some locations, thylakoids are stacked and are known as gana.
