This organelle is found in plant cells. the function of this organelle is to collect solar energy and use this to produce food, or glucose, for the plant. this organelle is the
a. leucoplast.
b. chloroplast.
c. mitochondrion.
d. golgi apparatus.

b. chloroplast. Chloroplast are organelles found only in plant cells that performs photosynthetic reactions. These photosynthetic reactions uses light energy, carbon dioxide and water to make glucose as the source of food for plants Thank you for your question. Please don't hesitate to ask in your queries. 

The correct answer is option b.

Explanation:

The leucoplast is an organelle found in plant cell with no pigment responsible for storage and synthesis of amino acids, lipids and other organic compounds with the pant cell.The the function of the of chloroplast is to convert absorbed solar energy  along with carbon dioxide and water in order to produce food for the plant. This  food formation process is known Photosynthesis.Mitochondria it is also an membrane bound organelle which produces energy in the cell. It is also known as power house of the cell.Golgi apparatus is membrane bound organelle responsible for modification and transportation of proteins and lipids around the cell.

Ibelieve it is b. proton.hope my answer has you : )
