Introduction to Permanent Tissue
There are four types of tissue in the body: epithelial, connective, muscle, and nervous. Permanent tissue refers to the types of tissue that are not replaced by new cells as the old ones die. Therefore their are four types of permanent tissue are adipose, bone, cartilage, and muscle.
Types of Permanent Tissue
There are four types of permanent tissue in the human body:
- Epithelial tissue: This type of tissue lines the organs and body cavities, and functions in protection, secretion, and absorption.
- Connective tissue: This type of tissue supports and connects the other tissues in the body.
- Muscular tissue: This type of tissue is responsible for movement.
- Nervous tissue: This type of tissue is responsible for transmitting signals throughout the body.
Simple Permanent Tissue
A simple permanent tissue is a type of organ that is made up of one type of cell. These tissues are found in the body’s organs, such as the liver and heart. Simple permanent tissues are responsible for performing specific functions in the body.
Parenchyma
cells are the most common type of cell in the plant body. They found in all parts of the plant, but are most abundant in the leaves and fruits. Parenchyma cells are simple, spindle-shaped cells that lack specialization. They thin-walled and have large vacuoles that allow them to store food and water. Parenchyma cells are responsible for photosynthesis, gas exchange, and water uptake.
Collenchyma
tissue is a type of plant cell wall. It composed of thick, elastic cellulose and pectin fibers. This type of tissue found in the stems and leaves of plants and helps to support them. The cells arranged in a series of parallel lines, and also are interconnected by the fibers. This type of tissue is also able to stretch and recoil, which allows plants to move in response to changes in their environment.
Types of Collenchyma Cells
- Collenchyma cells elongated and have a thin cell wall.
- They are living cells and also found in the cortex of plants.
- The cell wall composed of cellulose and pectin.
- The cell wall flexible and allows the cell to expand and contract.
- Collenchyma cells found in the stem and leaves of plants.
- They are responsible for providing mechanical support to the plant.
Complex Permanent Tissue
There are four main types of complex permanent tissue: epithelial, connective, muscular, and nervous tissue.
- Epithelial tissue is composed of cells that line the surfaces of organs and body cavities. It serves as a protective barrier and also helps to regulate the exchange of substances between the inside and outside of the body.
- Connective tissue is a versatile type of tissue that supports and connects other tissues and organs. However it contains a variety of cells that produce substances like collagen and elastic fibers that give the tissue its strength and flexibility.
- Muscular tissue has composed of cells that can contract, or shorten, to produce movement. There are three types of muscle tissue: skeletal, cardiac, and smooth.
- Nervous tissue composed of cells that transmit electrical signals from the brain and spinal cord to the rest of the body. However it enables the body to respond to stimuli and control its movements.
Secretory Tissues
The pancreas, salivary glands, and sweat glands are all examples of exocrine glands. Therefore these glands secrete their products (digestive enzymes, saliva, sweat) into ducts that empty into the lumen of a cavity or onto the surface of the body.
Where Permanent Tissues Found?
Permanent tissues found in the body’s organs and muscles.
What is Bone Tissue?
Bone tissue is the tissue that makes up bones. Bone tissue made up of cells called osteoblasts and osteocytes, and a mineral matrix. The mineral matrix made up of calcium and also phosphorus.
FAQs
1. What is permanent tissue?
Permanent tissue is a complex tissue found in plants that is involved in the structural support of the body and in the transport of materials throughout the body. Permanent tissue is made up of specialized cells that have stopped dividing and are in a mature, non-growing state. This type of tissue is found in the vascular bundles, the xylem, and the phloem of plants.
2. What are the types of permanent tissue?
There are three main types of permanent tissue: xylem tissue, phloem tissue, and sclerenchyma tissue. Xylem tissue is responsible for transporting water and minerals up from the roots of the plant, while phloem tissue is responsible for transporting organic molecules such as sugars between different parts of the plant. Sclerenchyma tissue provides structural support to the plant and is composed of thick-walled cells that are very rigid and strong.
3. How is permanent tissue formed?
Permanent tissue is formed through a process called differentiation. During this process, cells divide and take on specialized roles and functions. As the cell matures, it stops dividing and becomes a permanent tissue cell.
4. What are the functions of permanent tissue?
The main functions of permanent tissue are to provide structural support, transport water and nutrients, and store food. The xylem and phloem tissues are responsible for transporting materials throughout the plant, while sclerenchyma tissue provides structural support. Additionally, some permanent tissues, such as the parenchyma, also store food.
5. What are the differences between permanent tissues and other types of tissues?
Permanent tissues are characterized by cells that have stopped dividing and are in a mature, non-growing state. In contrast, other types of tissues such as meristematic tissues are composed of cells that are actively dividing and growing. Additionally, permanent tissues are more specialized than other types of tissues, meaning that they have specific roles and functions within the body.
