Anti Ageing - Qp1

The statement is true because a tissue is indeed a group of similar cells that perform a specific function and have a common origin. These cells work together to carry out a particular task in the body, such as providing support, movement, or protection. Each type of tissue, like muscle tissue or bone tissue, follows the same laws of growth and development, making the statement accurate.

The given statement describes the characteristics of a cell, stating that it is the simplest organized unit of living matter that can maintain itself at a higher energy level than its surroundings, grow, and reproduce. Based on this information, cells can be recognized as the basic units of life.

The statement that the human cell contains 26 chromosomes is false. The correct answer is false because the number of chromosomes in a human cell is actually 46. Chromosomes are thread-like structures made of DNA and contain genes that carry genetic information. In humans, there are 23 pairs of chromosomes, with one set inherited from each parent, resulting in a total of 46 chromosomes in each cell.

Cells are capable of absorbing nourishment, which is essential for their survival and functioning. They also have the ability to grow and repair themselves, allowing them to adapt to changes in their environment. Reproduction by division is another characteristic of cells, enabling them to multiply and create new cells. Cells also excrete waste products, removing harmful substances from their internal environment. Additionally, some cells possess the power of movement, allowing them to migrate and perform various functions within the organism.

Connective tissues are a diverse group of tissues that provide support, structure, and protection to other tissues in the body. Fibrous connective tissue is made up of strong fibers and is found in tendons and ligaments, providing strength and flexibility. Adipose tissue is responsible for storing fat and providing insulation and cushioning. Lymphoid tissue is involved in the immune response and includes lymph nodes and tonsils. Cartilage is a firm, flexible tissue found in the nose, ears, and joints, providing support and cushioning. Areolar tissue is a loose connective tissue that surrounds and supports organs and blood vessels. Bone tissue is hard and rigid, providing support and protection to the body.
