Simple permanent tissues are further classified into the following two types: (a) Parenchyma: Parenchyma forms the bulk of the plant body. It forms a barrier to keep different body systems separate. Practice more on Tissues. Classify permanent tissues and describe them. They are also found in the iris of the eye, in ureters and in bronchi of the lungs. Epithelium covers most organs and cavities within the body. (iii) Cells are usually loosely packed with large intercellular space. They have to move in search of food, mate and shelter; so they need more energy as compared to plants. The root tips of a plant were cut and the plant was replanted. But since these cells do not store food material or wastes materials they lack vacuole. The tissue consist of localised thickening in their cell walls. The cells are variable in shape and size. It provides mechanical support and elasticity to the plant body. Offered for classes 6-12, LearnNext is a popular self-learning solution for students who strive for excellence, Parenchyma is the most common living plant tissue.

The epidermis has thick cuticles and waxy substance to prevent the invasion of parasites. Lignin is a chemical substance present in the cell wall of plants which acts as a chemical and hardens i. Cutin is a chemical substance with waterproof quality covering the aerial parts of plants. Since they are arranged in a pattern of layers, the epithelium is called stratified squamous epithelium. (v) The cells are long and narrow make the plant hard and stiff. Each neuron has the following three parts: (i) The cyton or cell body: It contains a central nucleus and cytoplasm with characteristic deeply stained particles, called Nissl granules. It translocates prepared food from leaves to storage organs and growing parts of the body. The skin, the lining of the mouth, the lining of blood vessels, lungs alveoli and kidney tubules are all made of epithelial tissue. 8)In hydrophytes large air cavities are present in parenchyma to give buoyancy to the plants.Such type are called as aerenchyma.

Permanent tissue are classified into the following two types: (i) Simple permanent tissue (ii) Complex permanent tissue Simple permanent tissues: These tissues are composed of cells which are structurally and functionally similar. (iv) Stores nutrient and water in stem and root. Neurons are highly specialized for being stimulated and then transmitting the stimulus very rapidly from one place to another within the body. Write a short note on the epithelial tissue. This is because each cell type specialises in one particular function. they do not contain living protoplasm. It is a conducting tissue. It is also known as cork cambium. (b) Phloem: Like xylem, phloem is also vascular but has no mechanical function. Define the term “tissue”.

Xylem is composed of four different types of cells: (i) Tracheids (ii) Vessels (iii) Xylem parenchyma (iv) Xylem sclerenchyma Except xylem parenchyma all other xylem elements are dead and bounded by thick lignified walls. Why? In aquatic plants, large air cavities are present in parenchyma. Answer: Xylem and phloem are called as complex tissues as they are made up of more than one type of cells. The adipose tissue is abundant below the skin, between the internal organs and in the yellow bone marrow. Following are the differences between xylem and phloem: Xylem: 1. Example are cardiac muscles and smooth muscles. How are messages conveyed from one place to another within the body? (e) There are several thick layers. (ii) Dense regular connective tissue: It is fibrous connective tissue, characterised by ordered and densely packed collection of fibres and cells. 4. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. For example muscles of limbs or skeletal muscles. Such type of parenchyma tissue is called aerenchyma. 3. Answer: The simple permanent tissues of plants are: Parenchyma… Since they do not consume or need much energy, so most of the tissues of plants are supportive.
