What are the types of Simple Tissue?

Answer:

Tissue can be defined as a group of cells with similar shapes and functions are termed as tissues. They form a cellular organizational level, intermediate between the cells and organ system. Organs are then created by combining the functional groups of tissues.

Permanent tissues

Permanent tissues are tissues wherein the growth process has been ceased. These issues originate from both the primary and the secondary meristematic tissues and possess a definite shape and organization. However, they lack the potential to divide.

Based on their constituent cell, Permanent tissues can be classified into two major types:

  • Simple tissue – parenchyma, collenchyma and sclerenchyma
  • Complex tissue – xylem and phloem

Parenchyma

They are living cells and walled, soft in nature due to the presence of thin-walled cells.

Collenchyma

These are characterized by uneven thick-walled living cells. This unevenness in the thickening of the cell walls imparts partially hard giving mechanical support derived essentially from the elongated cells of the ground meristems, procambium sometimes.

Sclerenchyma

They have cells with thickened lignified walls, providing them strength and making them waterproof.
