Question

Define meristems?

Answer 1

Hint: A tissue is a collection of cells with similar configurations that collaborate to perform a certain purpose. Because plants are immobile, dead cells have been used to create tissues that give structural support. They must deal with adverse weather conditions such as severe winds, storms, and flooding, among other things. Permanent and meristematic tissues are two types of plant tissues.

Complete explanation:
The meristem is a type of tissue in plants. It is made up of cells that are not differentiated (meristematic cells) and can divide. The meristem's cells can develop into any of the plant's other tissues and organs. These cells divide until they become differentiated, at which time they stop dividing.
Plant cells that have been differentiated are unable to divide or create cells of a different type. Meristematic cells are developed cells that are either undifferentiated or incompletely differentiated. They are totipotent, meaning they can divide their cells indefinitely. The essential structure of the plant body is provided by the division of meristematic cells, which produces new cells for tissue development and differentiation, as well as the beginnings of new organs.
The cells are tiny with no or few vacuoles, and protoplasm entirely fills the cell.
Meristematic tissues are divided into three types: apical (points), intercalary (middle), and lateral (at the sides).

Note:
In plants, the meristem is a cell division and expansion capable area. These tissues have the ability to divide quickly in order to grow. They contribute to the vegetation's major growth. These cells are responsible for the plant's growth in length and diameter. Meristematic cells are live cubical cells with a large nucleus. There are no intercellular gaps in these cells since they are meticulously packed. By their position in the plant, apical (at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem portions between the locations at which leaves connect, and leaf bases, particularly of certain monocotyledons e.g., grasses) meristems are distinguished.
