A cell is the smallest unit of any living species and is responsible for functions, structural building and growth. Cells contain organelles inside them that have various functions and roles.
The labelling of structures are:
The roles of cell organelles are:
- The nucleus is the main hereditary and regulatory organelle of cells and stores the genetic material called DNA.
- Lysosomes have digestive enzymes that break the extra or damaged cells. They also digest some viruses and bacteria that invade the body.
- Centrioles are found in pairs near the nucleus and forms spindles during the process of mitosis and meiosis.
- The cytoplasm is a viscous fluid inside the cell membrane where all the organelle lies and functions as a medium in cellular chemical reactions.
- The cell membrane acts as a barrier between the outer and inner cell environment and allows the entry and exit of proteins transport.
- Mitochondria is the most vital cell organelle and produces the energy required for cell functioning. It is the place where chemical reactions occur to produce ATP.
Therefore, the correct labelling are A: Nucleus, B: Lysosome, C: Centriole, D: Cytoplasm, E: Cell membrane and F: Mitochondria.
