Answer:
Explanation: There are a number of structures which are found mostly in leaves than in roots, some of which are:
The large central vacuole is surrounded by its own membrane and contains water and dissolved substances. Its primary role is to maintain pressure against the inside of the cell wall, giving the cell shape and helping to support the plant.
The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin , which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell.
Plastids are membrane-bound organelles with their own DNA. Examples are chloroplasts and chromoplasts. Chloroplasts contain the green pigment chlorophyll and carry out photosynthesis. Chromoplasts make and store other pigments. They give flower petals their bright colors.
The glycocalyx is present in the human vascular and digestive system. Endothelial cells lining blood vessels have a glycocalyx to protect them from the sheer stress of blood flow, as well as to aid in cell attachment that helps the immune system and blood clotting
