(a) Cork cells possesses———on their walls that makes it impervious to gases and water. Water hyacinth float on the water surface because of the presence of the air cavities present in the parenchyma tissue. Epithelial cells with cilia are found in respiratory tract of our body Lining of blood vessels is made up of squamous epithelium
They are somewhat less flexible than loose connective tissue. They wander through connective tissues, clean up debris and remove bacteria and other antigens by phagocytosis. They join connective tissues to neighbouring tissues. Connective tissues, as the name implies, support and connect different tissues and organs of the body. There are mainly four different types of tissues present in vegas casino app our body. The combination of these components gives a delicate consistency to the loose connective tissue making it flexible and not very resistant to stress.
The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissue. Conducting tissues xylem and phloem are responsible for the survival of plants in the terrestrial environment. Cartilage is a connective tissue which provides support and flexibility to various parts of our body. Conduction of water is a function of xylem tissue whereas protection, gaseous exchange and transpiration are the function of epidermis. Meristematic tissues in plants are the dividing cells, which are responsible for plant growth in certain specific region. In areolar connective tissue, the fiber bundles are loosely arranged with wide spaces in between them.
Skin epithelial cells are arranged in many layers to prevent wear and tear. Simple squamous epithelial cells are extremely thin and flat and form a delicate lining. The epithelium is usually separated from the underlying tissue by an extracellular fibrous basement membrane. It is obvious that anything entering or leaving the body must cross at least one layer of epithelium. Cells in the epithelial tissue are tightly packed and form a continuous sheet.
Collagen fibres are the most widespread and made up of fibrous protein, collagen. They are widely distributed in every part of the body. Collagen fibers predominate, but elastic and reticular fibers are also present.
What is Areolar Connective Tissue?
It acts as a shock absorber and helps in maintaining body temperature in colder environments. They are found between many organs as a filling and act as a shock absorber and reservoir for salt and fluid. They are spindle-shaped and present between collagen fibres. Reticulate fibres consist of collagen and glycoproteins. Elastic fibres form a network and can be stretched like a rubber band. Collagen fibres are flexible and have high tensile strength (comparable to steel).
- There are two types of adipose tissue found in mammals, brown and white.
- The areolar connective tissue is a type of connective tissue that is present throughout the human body.
- (c) Writing with hand- is a function of voluntary muscles
- Areolar connective tissue is a loosely arranged connective tissue that is widely distributed in the body and contains collagen fibers, reticular fibers, and a few elastic fibers embedded in a thin, almost fluid-like ground substance.

Short Answer Questions
The cells also secrete a thin gel of polysaccharides, which together with fibres make matrix or ground substance. The loose connective is well vascularized and has no specific constant form. Differentiation is a process by which the cells divide meristematically to take a permanent shape, size and function (b) Cells derived from the division of meristematic tissues take up specific roles and gradually lose their ability to divide. Xylem is made up of four different types of cells (elements), namely
Frequently Asked Questions on Areolar Connective Tissue
As the name suggests, the connective tissue functions to connect the cells of muscles and nerves. The areolar connective tissue appears different in various organs and may even appear compact when the areolar tissue of the skin is viewed with a microscope making it difficult to be distinguished from dense irregular connective tissue. Areolar connective tissue is the type of tissue which connects and surrounds different organs in the human body. The areolar connective tissue is a type of connective tissue that is present throughout the human body.
Where is the reticular connective tissue found?
This type of tissue is present in the dermis of the skin. White adipose tissues protect kidneys and are also found at the back of the eye, in the hump of camels, blubber of whales, etc. A group of cells along with intercellular substances that perform a specific function is called tissue. (c) Parenchyma and collenchyma are two simple permanent tissues, whereas xylem and phloem are two complex permanent tissues. The basic differences between meristematic and permanent tissues of plants are tabulated below
It consists of relatively unspecialised cells with thin cell walls. Parenchyma is the most common simple permanent tissue. This minimizes the effect of heat and reduces the loss of water. (d) Sieve tube cells They have two functions, storage and lateral food conduction.
Where is loose connective tissue found?
(d) Epithelial cells with cilia are found in———of our body (d) Movement of chocolate in your intestine- is a function of involuntary muscles (c) Writing with hand- is a function of voluntary muscles (b) Pumping of the heart- is a function of involuntary muscles
It fills the space inside the organs, supports internal organs and helps in the repair of tissues. Connective tissue which connects muscles to bones is tendons. Adipose tissue present below the skin and between internal organs stores fat. (d) Cartilage is a form of connective tissue Meristematic tissues in plants are What type of epithelial cells are responsible for that?
Reticular tissue is a specific form of connective tissue predominating in several regions with high cellular content. Fibroblasts, known as reticular cells, are the cells that produce reticular fibres. Scleroderma- It is characterised by thickening and hardening of the connective tissue. The immune system of the body starts attacking its own tissues.

Fats are stored in human body as Answer is Tendons are non-fibrous tissue and fragile. (c) Tendons are non-fibrous tissue and fragile (b) Two bones are connected with ligament
Epithelial tissues are covering or protective tissues in the animal body. Which of the following tissues has dead cells? In this chapter, students will learn about different types of tissues and their properties. There are two types of adipose tissue found in mammals, brown and white.
- Epithelial cells form a barrier that keeps different body systems separate.
- Meristematic tissues in plants are
- Since they are arranged in a pattern of layers, the epithelium is called stratified squamous epithelium.
- In humans, cartilage is present between the bones of the vertebral column, in the external ear, nose and hands.
Loose connective tissue function and examples
The fibres and cells are loosely arranged in the semi-fluid matrix. Fibroblasts are found in developing tissues and play an important part in wound-healing. Fibroblasts or adipose cells are stationary and macrophages, mast cells, monocytes, lymphocytes are migrating cells. They secrete different types of fibres and matrices.
The fibres provide stroma (a soft skeleton) to sustain the lymphoid organs (red bone marrow, lymph node stromal cells and spleen). Although reticular tissue is only found at specific locations, reticular fibres are widely dispersed throughout the body. Reticular connective tissue is located in the bone marrow, Peyer’s patches, lymph nodes, kidney, liver, and spleen. The other type of connective tissue disorder is autoimmune.
Except for phloem fibres, other phloem cells are living cells. Phloem fibres possess narrow lumen and they are thick-walled elongated spindle-shaped dead cells. The muscular tissue which functions throughout the life continuously without fatigue is Areolar tissue fills the space inside the organs and supports internal organs and helps in the repair of tissue. Cells in these tissues are filled with fat globules. Renal tubules and corpuscles in the kidney are formed by Cuboidal epithelium tissue.
Reticular fibres support the early extracellular matrix during the formation of scar tissue, the healing of wounds, and general development. They form the initial structure of every tissue they are a part of, demonstrating their essential support function. Due to the distribution of reticular fibres, it exhibits a branching, and mesh-like appearance frequently referred to as reticulum (reticulin). It may be localised, only affecting a part of the skin or systemic, impacting vital organs. The systemic lupus erythematosus (SLE) – It is an inflammatory disorder of the skin and internal organs.
