What is the main function of a cell?

Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.

What are human tissues?

Human body tissue makes up organs and other body parts. There are four types of tissue: muscle, epithelial, connective and nervous. All tissues are made up of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart.

Can blood be called a tissue?

Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.

What are cells?

(sel) In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.

Do cells make up tissues?

Cells group themselves together to make up the tissues and organs of our bodies.

What are three functions of cells?

Three major functions of cell are Energy generation, Molecular transport and reproduction. Explanation: Cells are the basic structural and functional unit of life.

What do tissues help in answer?

What are Tissues? In simple terms, tissue can be defined as a group of cells with similar shape and function are termed as tissues. They form a cellular organizational level, intermediate between the cells and organ system. Organs are then created by combining the functional groups of tissues.

What are the five life functions of cells?

The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction.

Where are tissues found in the body?

4: There are 4 different types of tissues in our body. Nervous tissue is found in the brain, spinal cord, and nerves. Muscular tissue such as cardiac, smooth, and skeletal muscle. Epithelial tissue lines the GI tract organs and other hollow organs and is found on the skin surface (epidermis).

What are the 4 types of cells?

• Epithelial Cells. These cells are tightly attached to one another. …
• Nerve Cells. These cells are specialized for communication. …
• Muscle Cells. These cells are specialized for contraction. …

Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that’s crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it’s this molecule that transports oxygen from your lungs to other parts of the body.

What is tissue answer?

In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Why are tissues called tissues?

The noun tissue comes from the Old French word tissu, meaning “a ribbon, or belt of woven material.” In fact, as a verb, tissue means “weave fabric strands.” Today, we think of tissues as the disposable paper for blowing our noses or packing presents.

Where do cells come from?

The short answer is that all cells come from other cells.

Cells can only be formed when another cell divides to make 2 “daughter cells” that have the same DNA. Sometimes 2 cells will join to form one, such as a fertilized egg cell. Their DNA is combined in the new cell.

What is tissue class 9 short answer?

What is a tissue class 9 answer?

Answer: Group of cells that are similar in structure and perform same function is called a tissue.

How do you explain tissue to a child?

Tissues are groups of cells that work together to do a job in the body. They are a group of cells having the same origin, structure and function. The cells look the same or almost the same. The work the cells in a tissue do is the same or almost the same.

What life processes do cells perform?

Cells perform 5 processes to keep them alive: metabolism, respiration, diffusion, osmosis, and active transport. METABOLISM – the sum total of all chemical changes that take place in living organisms.

How do cells sustain life?

Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs.

What does a cell need to do to survive?

To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.

What are the abilities of a cell?

Cells ingest molecules through their plasma membranes. Cells contain a special collection of molecules that are enclosed by a membrane. These molecules give cells the ability to grow and reproduce. The overall process of cellular reproduction occurs in two steps: cell growth and cell division.
