VR Tour For Std. 9 Ch. 6. Tissues

What's Included in Virtual tour of this chapter

There are unicellular as well as multicellular organisms. In unicellular organisms, a single cell is capable of performing several functions and in multicellular organisms, there is a division of labor. A group of cells that carries out a specific function is called a tissue. A tissue gives the highest possible efficiency of function in multicellular organisms. Plants have two types of tissues. One is the meristematic tissues and the other is the permanent tissues. The covering or protective tissues in the animal body are epithelial tissues. It also forms a barrier to keep different body systems separate. The main function of the muscular system in animals is movement. Muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. At last, we will learn about the nervous tissue in animals.

Virtual tour 1: Meristematic Tissue of plants

Plant tissues can be broadly divided into two main types. These are Meristematic tissue and Permanent tissue. Meristematic tissues are living tissues that are composed of immature cells that are capable of division throughout life. These tissues are found in growing regions of plants. Depending on the region where they are located, meristematic tissues are classified as apical, lateral, and intercalary meristem.

Virtual tour 2: Simple permanent tissue

The process by which cells of the meristematic tissues convert themselves into permanent tissue by taking a fixed shape, size, and function is called differentiation. In this virtual tour, we will learn about simple permanent tissues in the plant. Simple permanent tissues are made up of only one type of cell. All the cells that make up the tissue are similar and have the same structure. Simple permanent tissues are again classified into three main types. They are parenchyma, collenchyma, and sclerenchyma.

Virtual tour 3: Epidermal and Guard Cells

In this virtual tour, we will learn about Epidermal and Guard cells. The epidermis is a single layer of cells that covers plants’ leaves, flowers, roots, and stems. It is the outermost cell layer of the plant body and plays a protective role in the plant. Guard cells are specialized plant cells that surround each stomata. They help to regulate the rate of transpiration by opening and closing the stomata.

Virtual tour 4: Complex permanent tissue

After exploring the simple permanent tissues we will now learn about complex permanent tissues. It comprises different kinds of cells. These different types of cells coordinate with each other and perform a common function in these tissues. Two Complex Permanent Tissues are – Xylem and Phloem. Their main function is to carry food and water in the plant.

Virtual tour 5: Epithelial Tissue

After learning in detail about plant tissues we will now learn about animal tissues. The covering or protective tissues in the animal body are epithelial tissues. The main function of the epithelial tissues is to act as a barrier and separate different organs and systems from one another. They are found in the lining of the blood vessels, in the small intestine, Kidney tubules, Skin of the human body. Epithelial tissues are classified into the squamous, columnar epithelium, cuboidal, and stratified squamous epithelium.

Virtual tour 6: Connective Tissue

We will learn about connective tissue in animals. They are loosely bound cells present in the intercellular Matrix. This matrix can be of different types: Dense, Rigid, Fluid, or Jelly-like. The nature of the matrix varies depending upon the functionality of the connective tissue. The different types of connective tissues in our body include areolar tissue, adipose tissue, bone, tendon, ligament, cartilage, and blood.

Virtual tour 7: Muscular Tissue

The main function of the muscular system is movement. Muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role.

Virtual tour 8: Nervous Tissue

Nervous tissue is composed of neurons. Nervous tissue is found in peripheral nerves throughout the body, the brain, and the spinal cord. Usually, each neuron has a single long part called the axon, and many short branched parts called dendrites. The nervous system is responsible for the control of the body and communication among its parts.
