Neurons - the nerve cells that make up the brain and nervous system, look different from all other cells in the body and from one another. All nerve cells have recognisable shapes, but no two look exactly alike. Nerve cells, once damaged, cannot be regenerated as they have lost the power of regeneration.

The central vacuole is a cellular organelle found in plant cells. It functions to hold materials and wastes. It also functions to maintain the proper pressure within the plant cells to provide structure and support for the growing plant.

The cells of meristematic tissue are very active. They have dense cytoplasm, thin cellulose walls and prominent nuclei. They lack vacuoles.

Cartilage is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs and many other body components.

Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases).

Glands, derived from the invagination and ingrowths of lining epithelia into underlying connective tissue, are composed mainly of epithelial cells in adults and are considered a type of epithelial tissue.

A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone or muscle to muscle and is designed to withstand tension. Tendons and muscles work together and can only exert a pulling force.

A is true, but R is false. Sclerenchymatous tissues have thick cell walls, but the cell wall has no deposition of suberin. It has deposition of lignin.

Nerve and muscle fibres are characterised by excitability and irritability. They work in association with each other and respond to stimuli equally.

Areolar connective tissue is found between the skin and muscles, around blood vessels and nerves and in the bone marrow. It fills the space inside the organs.
