The lamina is green due to the chlorophyll inside. It is flat to maximise the surface area so that it can absorb as much sunlight as possible, while its thin nature is to facilitate gaseous exchange(and make it easier to absorb sunlight).
A fern has three main parts of the body that are the fronds, rhizome, and the sporangia. On the fronds, the flat, green leaf blades are lamina and between the lamina and rhizome is the part of the stalk called the stipe.
The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.
scale insects are flat and green to blend in with flowers and weeds
I want the definition of this word lamina
The lamina is the expanded portion or blade of a leaf and it is an above-ground organ specialized for photosynthesis. For this purpose, a leaf is typically, to a greater or lesser degree, flat and thin, to expose the chloroplast containing cells (chlorenchyma) to light over a broad area, and to allow light to penetrate fully into the tissues.
If the lamina is in two dimensions (i.e. not curled round into a third dimension) then the centre of gravity will be somewhere within the flat shape. The position of the centre of gravity will depend on the distribution of mass across the lamina. If the lamina is curled round into a third dimension then the centre of gravity will be somewhere within the volume enclosed, fully or partially, by the lamina; this may or may not be on the lamina.

Leaves are broad and flat so that they can absorb large amounts of light energy from the sun, which is needed in order for photosynthesis (the conversion of carbon dioxide and water into glucose) to occur. The green colour signifies the fact that the plant contains chlorophyll, which is a pigment needed to trap light energy.
