Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
I am located in the leaves of plants, but NOT the roots. Who am I?
A
Lysosomes
B
Chloroplasts
C
Vacuole
D
Mitochondria
Explanation: 

Detailed explanation-1: -Chloroplasts are found only in plants and photosynthetic algae. (Humans and other animals do not have chloroplasts.) The chloroplast’s job is to carry out a process called photosynthesis.

Detailed explanation-2: -In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Detailed explanation-3: -Palisade mesophyll layer: Tightly packed layer of elongated cells located directly below the upper epidermis. These cells contain most of the chloroplasts in a leaf.

Detailed explanation-4: -Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.

Detailed explanation-5: -The plant cells which contain chloroplasts are mostly parenchyma cells but also collenchyma tissue have some chloroplasts. A plant cell which contains chloroplasts is typically called a chlorenchyma cell.
