Plant and Animal Tissues

 Plant tissues can be grouped into two basic types: meristematic and permanent tissues.

The epidermis cells is a single-layer of cells that covers the leaves, flowers, roots and stems of plants.

Cuboidal epithelium is composed of cube-shaped cells and is specialized for secretion, absorption, and excretion in structures like kidney tubules and glands.

Stomata are tiny pores found on the surface of leaves that allow for the exchange of gases such as carbon dioxide and oxygen during photosynthesis and respiration.

Phloem translocates prepared food from leaves to the storage organs and growing parts of the plants.

Glandular epithelium is a specialized type of epithelial tissue that forms glands, which are responsible for secreting substances like hormones, enzymes, or mucus.

Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem.

Squamous epithelium consists of thin, flat, scale-like cells. It is found where diffusion or protection is needed, such as in the lining of the mouth, blood vessels, and skin.

Depending on their position in the plant, meristems are divided into apical, lateral and intercalary.

Smooth muscles are involuntary, non-striated muscles found in the walls of internal organs (viscera) like the stomach, intestines, and blood vessels.

Lignin is a hard substance with great tensile and compressional strength deposited in the cell walls of sclerenchyma.

A tissue is defined as a group of cells that are similar in structure and work together to perform a specific function in an organism.

 Correct answer is Collenchyma. Collenchyma provides extra structural support, particularly in regions of new growth.

The three main types of muscular tissue are skeletal (striated), smooth (unstriated), and cardiac (found specifically in the heart).

Adipose tissue is a type of connective tissue specialized for storing fat (lipids) in cells called adipocytes.

Primary growth in plants refers to the increase in length or height, which is driven by the activity of apical meristems located at the tips of roots and shoots.

The four fundamental types of animal tissues are epithelial, connective, muscular, and nervous tissue.

Peristalsis is the involuntary, rhythmic contraction and relaxation of muscles in the digestive tract that moves food along.

Tendons are tough, fibrous connective tissues that connect skeletal muscles to bones, allowing for movement.

Fluid connective tissue in the human body consists of blood and lymph. These tissues transport nutrients, gases, and waste products throughout the body.

 The main function of the xylem is to carry water and mineral salts upward from the root to different parts of shoots.

As roots and stems grow older with time, tissues at the periphery become cork cells. Cork cells are dead, have no intercellular spaces and the cell walls are heavily thickened by the deposition of suberin. They prevents loss of water.

Haemoglobin is the iron-containing protein in red blood cells (RBCs) that binds oxygen for transport. Bilirubin is a waste product of haemoglobin breakdown, while fibrinogen is involved in clotting.

Osteoblasts are bone-forming cells, and when they become trapped in the matrix they secrete, they are called osteocytes. Erythrocytes are red blood cells, and chondrocytes are cartilage cells.

Striated muscles are attached to the skeleton and are under conscious control, which is why they are called voluntary muscles. Cardiac muscles are striated but involuntary, and smooth muscles are non-striated.

 Parenchyma serves as a food storage tissue. It stores starch, protein, fats, oils and water in roots, tubers (e.g. potatoes), seed endosperm (e.g. cereals) and cotyledons (e.g. pulses and peanuts).
