Question

Cavity formed by the separation of cells in a tissue is
(a) Schizogenous cavity
(b) Lysigenous cavity
(c) Schizolysigenous cavity
(d) Stomatal complex

Answer 1

Hint: This is the most common type of intercellular space or cavity that occurs in the cells and is formed when the young and dividing meristematic cells get matured.

Complete answer:
In plants, there are some cells in different parts that are young and in a continuous division mode. Initially, these cells do not have any intercellular spaces between them but as they get older, their walls split apart and small intercellular spaces develop between the cells. These spaces are known as Schizogenous cavities. These types of cavities are the most common types of cavities between the cells and result from the separation of cells in a tissue, especially, separation of the cell walls. The cell walls separate from each other along with more or less extended areas of the contact between the cells. Now, a question may arise that if a cavity is formed then what happens to the substances that were present there. Actually, those intercellular substances get dissolved partly, and thus an intercellular space is developed which we call a cavity. With time, this intercellular space gets bigger, and then it is known as the Schizogenous cavity. So, in simple terms, the Schizogenous cavities are comparatively bigger than the ordinary intercellular spaces.
So, the correct answer is the ‘Schizogenous cavity’.

Note: Lysigenous cavities are not formed by the separation of cells or cell walls. These are the intercellular spaces that arise due to the dissolution of entire cells and this is the reason that these intercellular spaces are named as Lysigenous. These spaces are used in the storage of water, oils, and gases and commonly found in plants that grow in water or watery areas.
