Final answer:
Primary meristem produced by mitosis at the apical meristems differentiates into protoderm, ground meristem, and procambium, yielding dermal, vascular, and ground tissues respectively. This process allows plants to undergo primary growth, extending in length and differentiating into permanent, specialized tissues.
Step-by-step explanation:
The type of meristematic tissue produced by mitosis that then differentiates is known as primary meristem. This includes the apical meristems, which differentiate into three main types of tissues: protoderm, giving rise to new epidermis; ground meristem, producing ground tissue; and procambium, which forms new xylem and phloem. These meristematic tissues are found at the tips of stems and roots, enabling plants to grow in length through primary growth.As the apical meristem cells divide, they differentiate and become specialized, forming permanent tissues that lose their ability to divide further. These specialized cells are organized into dermal, vascular, and ground tissue. Dermal tissue protects the plant; vascular tissue is responsible for transport; and ground tissue plays roles in photosynthesis, support, storage, and as a matrix for the vascular tissue.
