Which tissue is derived from the apical meristem?

Answer

The tissues derived from the apical meristem are primarily involved in primary growth, which includes the elongation of roots and shoots. The apical meristem gives rise to several types of tissues:

1. Protoderm:
   • Derivatives: Epidermis
   • Function: Forms the outer protective layer of the plant, which serves as a barrier against environmental factors and helps in the absorption of water and nutrients.
2. Ground Meristem:
   • Derivatives: Ground tissues such as parenchyma, collenchyma, and sclerenchyma.
   • Function: Provides structural support, storage, and photosynthesis. Each type of ground tissue has distinct functions:
     • Parenchyma: Involved in storage, photosynthesis, and tissue repair.
     • Collenchyma: Provides flexible support to growing parts of the plant.
     • Sclerenchyma: Provides rigid support and strength.
3. Procambium:
   • Derivatives: Vascular tissues, including xylem and phloem.
   • Function: Responsible for the transport of water, nutrients, and organic compounds. Xylem transports water and minerals, while phloem distributes the products of photosynthesis.

These tissues collectively contribute to the primary growth of the plant, allowing it to increase in length and establish new shoots and roots.
