Answer 1

The correct answer is Mitochondria.

Explanation:

Mitochondria is a double membrane organelle.
It is semi-autonomous and can control some of its functioning.
Its number varies in plant and animal cells.
Plants have chloroplast, nucleus, mitochondria, and ribosomes.
Mitochondria in the energy production unit in the plant cell.
Here, the ATP synthesis takes place.
The glucose produced by photosynthesis is broken down to produce energy in the form of ATP in the mitochondria.
The proton gradient that is generated during the electron transport results in the formation of ATP.
This process is equivalent to the respiratory system and is called as cellular respiration.

Hence, mitochondria produce energy in plant cells using the respiratory system.

Confusion Points

Chloroplast helps in Photosynthesis and the formation of Glucose, with the help of Light Energy.
Mitochondria on the other hand help in cellular respiration which breaks down sugar into ATP inside plant cells.

Additional Information

Nucleus	It is a double membrane structure. It contains genetic material. It acts as the control unit and controls the cell's functioning.
Chloroplast	It is a double membrane organelle. It is semi-autonomous and can control some of its own functioning. It has chlorophyll pigments that use light energy and converts it to chemical energy. It is the organelle in plant cells where photosynthesis takes place.
Ribosomes	It is a single membrane structure. It consists of large and small subunits. The chloroplast and mitochondria have their own ribosome. It is the site of protein synthesis.
