Answer:
They are called Stomatas.
Explanation:
A waxy cuticle covers all aerial surfaces of land plants to minimize water loss. These leaf layers are clearly visible in the scanning electron micrograph. The numerous small bumps in the palisade parenchyma cells are chloroplasts.

2. Since it’s developmental anatomy
Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases ~ prophase, metaphase, anaphase, telophase and cytokinesis
Agree, the cells are the basic unit of life therefore it’s agree. The cell is the basic unit or cell of any organism.
