Question

On the basis of location, classify meristematic tissues.

Answer 1

The cells of meristematic tissues are called meristems. Meristems are classified by their location in the plant as apical, lateral and intercalary.

1. Apical Meristem - located at root and shoot tips

   • Apical meristems give rise to the primary plant body

   • These are responsible for the extension of the roots and shoots.

2. Lateral Meristem – present in the vascular and cork cambia

   • These are known as secondary meristems because they are responsible for

secondary growth, or increase in stem girth and thickness.

1. Intercalary Meristem – present at internodes, or stem regions between the places at which

leaves attach, and leaf bases, especially of certain monocotyledons—

e.g., grasses.

• These are responsible for increasing the length of the internodal regions.
