The cells called chloroplasts (chlorenchyma tissue, a type of parenchyma) ) which contain the green pigment called chlorophyll are responsible for the green colour of leaves.

The leaf is considered to be a plant organ, typically consisting of the following tissues:

1. An epidermis that covers the upper and lower surfaces
2. An interior chlorenchyma called the mesophyll
3. An arrangement of veins (the vascular tissue).

Thus, the green chlorophyll is in the interior chlorenchyma. However, because the leaf is very flat and the epidermis is usually transparent, we can see the green tissue.

Detailed explanation of the above
---------------------------------------------------------------------------------

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.

Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. It is derived from the Greek words chloros which means green and plast which means form (in biological terms it can be more roughly translated as organelle or cell).

In green plants, chloroplasts are surrounded by two lipid-bilayer membranes.

Chloroplasts are observable morphologically as flat discs usually 2 to 10 micrometer in diameter and 1 micrometer thick. The chloroplast has a two-membrane envelope termed the Inner & Outer membrane respectively. Between these two layers is the intermembrane space.

The material within the chloroplast is called the stroma. Within the stroma are stacks of thylakoids, the sub-organelles where photosynthesis actually takes place. Embedded in the thylakoid membrane is a dish of chlorophyll molecules known as the antenna complex.

Parts Of A Leaf Cell

Mostly the mesophyll of the cell.It is made of palisade and spongy parenchyma.These two parechyma have double row of chloroplasts than normal plant cell
Besides the extra chloroplasts, the flat nature of leaf is more green than other plant parts

Because variegated leaves are not as efficient at photosynthesis as a full green leaf, there is more chlorophyll in the green parts so there is more photosynthesis occuring, the variegated part lacks stomata because they dont photosynthesize so they are unnecessarily
