Question

Parenchyma is a type of__________________
(a) Connective tissue
(b) Nervous tissue
(c) Complex tissue
(d) Simple tissues

Answer 1

Hint: Permanent tissues are tissues in which the cells do not generally divide further. Parenchyma is a type of permanent tissue. It forms the major component within organs. They are thin-walled and made up of cellulose.

Complete solution:
Simple tissues are tissues that are made up of only one type of cell. The various simple tissues in plants are parenchyma, collenchyma, and sclerenchyma.
-Parenchyma forms the major component within organs. The cells of parenchyma are generally isodiametric. They are either closely packed or have little intercellular spaces. Parenchymatous cells perform various functions like photosynthesis, storage, and secretion.
-In dicotyledonous plants, collenchyma occurs in layers below the epidermis. Collenchyma provides mechanical support to growing parts of the plant, such as the leaf's young leaf and small petiole.
-Sclerenchyma consists of cells that are usually dead and without protoplasts. It provides mechanical support to organs.

Additional information:
Connective tissues are the most abundant tissues in the body of complex organisms. These tissues are widely distributed in the body. These tissues perform a special function of linking and supporting other tissues/organs of the body.
Nervous tissues exert massive control over the body's responsiveness to changing conditions. The functional unit of the nervous system, Neurons, are excitable cells. Neuroglial cells, which constitute the rest of the neural system, protect and support neurons.
Complex tissues are permanent tissues made of more than one type of cells, and all these cells work together as a single unit. The complex tissues found in plants are:- Xylem and Phloem.
-Xylem acts as a conducting tissue for water and minerals from roots to the stem and leaves. It provides mechanical support to the parts of the plant. Xylem constitutes four different kinds of elements:- Tracheids, Vessels, Xylem fibres, and Xylem parenchyma.
-Phloem is responsible for transporting food materials from leaves to other parts of the plant. Phloem comprises four elements:- Sieve tubes, Companion cells, phloem parenchyma, and phloem fibres.

So, the correct answer is 'Simple tissues'.

Note:
Parenchyma is a type of simple tissue that is made up of only one type of cell. Although they may be round, polygonal, spherical, oval, or elongated in shape, the cell type will be the same.
