Which of the following organelles is found only in plants?
A
ribosomes
B
nucleus
C
mitochondria
D
central vacuole
Explanation: 

Detailed explanation-1: -Chloroplasts are double-membraned organelles present only in plant cells. Lysosomes, ribosomes and mitochondria are present in both plant and animal cells.

Detailed explanation-2: -Many plant cells have a large, single central vacuole that typically takes up most of the room in the cell (80 percent or more). Vacuoles in animal cells, however, tend to be much smaller, and are more commonly used to temporarily store materials or to transport substances.

Detailed explanation-3: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall.

Detailed explanation-4: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
