Solution
The correct option is B A and D
The correct option is B.
Explanation of the correct option:
- Mitosis is a type of cell division which occurs in somatic cells of the body. It is responsible for the growth of the tissues of multicellular organisms.
- Mitotic cell division is divided into four stages or phases: - Prophase, Metaphase, Anaphase and Telophase.
- Meiotic cell division involves two cell divisions- Meiosis I and Meiosis II.
- Collenchyma is a type of simple permanent tissue that provides mechanical support, stiffness and flexibility to plants.
