Question

How do specialised cells form tissues?

Answer 1

Answer:

Explanation:

Most living organisms are composed of several cells, but are these cells irregular or disordered? Does each of them work separately from the other?

Cells are specialised in their functions. Each group of specialised cells forms what is known as a tissue. For example, the heart’s muscular cells are arranged to form the muscular tissue of the heart wall.

If the cells forming the tissue are symmetrical with each other in terms of shape, structure, and function, then the tissue is called a simple tissue. If the tissue is composed of more than one type of cell, then it is called a compound tissue.

Types of tissues vary in regards to the differences and diversity of living organisms, as do the activities and vital functions of the tissues.

In most living organisms, the tissues are organized into groups called organs. Each organ is a group of tissues working in harmony to perform certain functions. Such tissues and organs are present in both plants and animals.

For example, the heart is an organ in multicellular organisms such as humans. It is mainly composed of heart muscular tissue, nerves, and connective tissue. The heart muscles, nerves, and connective tissue collaborate together to pump the blood from the heart to all parts of the body.

Groups of organs working together form what is known as a system. The heart, blood and blood vessels form the circulatory system of humans. Systems organise and integrate together to form the whole body of the organism. The human body is composed of several systems besides the circulatory system, such as the skeletal system, muscular system, nervous system, digestive system, respiratory system, excretory system , reproductive system and so on.

Answer 2

Answer:

specialized cells perform specialized function in multicellular organisms. Groups of specialized cells cooperate to form a tissue like muscles . Different tissue are turn in grouped together to form larger function units called organs .
