(a) — (viii) Parenchyma is a type of simple permanent tissue. It contains living cells. The primary purpose of the parenchyma is to store and absorb food. (b) — (xii) Collenchyma is a mechanical tissue in young dicotyledonous stems and provides mechanical support and elasticity. The tissue is made up of cells that have thickened cell walls at their corners. (c) — (ii) Sclerenchyma is a type of simple permanent tissue that is composed of dead cells. The cell walls of sclerenchyma are greatly thickened with chemicals, lignin . Their main function is to provide mechanical support. (d) — (x) Xylem is a complex/ conducting/ vascular tissue. The xylem's primary role is to transport water and mineral salts from the roots to various sections of the shoots. (e) — (ix) Translocation is the movement of materials from leaves to other tissues throughout the plant. Translocation is carried out by the phloem tissue. (f) — (v) Squamous epithelium is a compact tissue made up of thin, flat, irregular-shaped cells that fit together like floor tiles. It can be found in the lining of alveoli, a nephron's bowman's capsule, and blood vessels. (g) — (iii) Striated muscle is a type of muscle fibre. These are also known as striped, skeletal, or voluntary muscles. Since they are attached to the bones and are responsible for body movements, they are called skeletal muscles. (h) — (i) Cardiac muscles are involuntary muscles. The fibres of this muscle are branched and multinucleated. These fibres are distinguished by the presence of intercalating discs. They serve as stimulants. (i) — (vi) Neuron is the structural and functional unit of the nervous system. It has three parts: cell body, axon, and nerve endings. A single long part (process) projecting out of soma (cell body of a neuron) is called the axon. (j) — (iv) Haversian canals are a series of microscopic tubes in the outermost region of bone called cortical bone that allows blood vessels and nerves to travel through them.

Match the following columns (I) and (II): Column I Column II (a) Fluid connective tissue (i) Subcutaneous layer (b) Filling of space inside the organs (ii) Cartilage (c) Striated muscle (iii) Skeletal muscle (d) Adipose tissue (iv) Areolar tissue (e) Surface of joints (v) Blood (f) Stratified squamous epithelium (vi) Skin

(a) - (v) Fluid connective tissue links the different parts of the body and maintains continuity in the body. It includes blood and lymph. (b) - (iv) Areolar tissue is a loose and cellular connective tissue. It is a type of connective tissue that joins skin to muscles, fills spaces inside organs and is found in blood vessels and nerves. (c) - (iii) Striated muscle is a type of muscle fibre which is also known as striped, skeletal or voluntary muscle. Since it is attached to the bones and is responsible for body movements, it is called skeletal muscle. (d) - (i) Adipose tissue is the modified areolar tissue. It is an aggregation of fat cells or adipocytes. These fat cells provide energy and help in insulation of the body. (e) - (ii) The cartilage is a specialised connective tissue which is compact and less vascular. The main function of this tissue is to provide support and flexibility to the body parts. It is found in nose, ears, etc. (f) - (vi) Stratified Squamous Epithelium is composed of many layers of cells. It is present in the epidermis of skin, oesophagus, mouth and cornea.

Match the following columns (I) and (II): Column I Column II (a) Parenchyma (i) Thin-walled, packing cells (b) Photosynthesis (ii) Carbon fixation (c) Aerenchyma (iii) Localised thickenings (d) Collenchyma (iv) Buoyancy (e) Permanent tissue (v) Sclerenchyma

(a) - (i) Parenchyma is a tissue that consists of thin-walled living cells. It serves as a packing tissue. It fills the spaces between other tissues and maintains the shape and firmness of the plant due to its turgid cells. (b) - (ii) Carbon fixation is the conversion process of inorganic carbon to organic compounds by living organisms. This process occurs during photosynthesis. (c) - (iv) In hydrophytes (aquatic plants) such as water hyacinth, Hydrilla , large air cavities are present in parenchyma to give buoyancy to the plants. Such a type of parenchyma is called aerenchyma. (d) - (iii) Collenchyma is a mechanical tissue in young dicotyledonous stems and provides mechanical support and elasticity. The tissue consists of cells having localised thickening in their cell walls. (e) - (v) Sclerenchyma is a simple permanent tissue. This tissue is made of dead cells which provide mechanical support and rigidity. Column I Column II (a) Parenchyma (i) Thin-walled, packing cells (b) Photosynthesis (ii) Carbon fixation (c) Aerenchyma (iii) Localised thickenings (d) Collenchyma (iv) Buoyancy (e) Permanent tissue (v) Sclerenchyma
