Cells of the ________ contain chloroplasts.

a. epidermis

b. vascular tissue

c. stomata

d. mesophyll

A cell is defined as the basic functional and structural unit of a living organism. Robert Hooke in 1665, first coined the term cell and he was the first to discover cell. The literal meaning of a cell is called small compartments. Anton van Leeuwenhoek first discovered a living cell. It is believed that about 3.6 billion years ago the first cell originated.

Mesophyll cells are the layer of cells below the epidermis of dicot leaves, otherwise called the “middle leaf.” Two arrangements of parenchyma cells are typically found in mesophyll cells of most leaves such as the spongy parenchyma and the palisade parenchyma. The palisade parenchyma is otherwise known as the palisade mesophyll. In scanning electron micrographs, the chloroplasts can be visible as small pores in the palisade parenchyma cells. These are also present in the spongy parenchyma but lesser in number than palisade parenchyma.

The epidermis is the upper layer to the mesophyll layer. Chloroplast present in the mesophyll.

The vascular tissues are for transportation purposes in plants.

The guard cell of stomata only contains chloroplast.

Therefore, ‘d’ is the correct option.

Palisade mesophyll cells contain chloroplast.
