Question

through a brief report describe the organisation of cells, tissues, organ and system

Answer 1

A group of cells having the same function and shape are organized into tissues.Each tissue performs a certain job.Bones and muscles are examples of tissues.
Different types of tissues working together to perform a special function make an organ.

(The heart is an organ made of muscle tissues,nerve tissues,and connective tissues that work together to pump blood throughout the body.The stomach is another organ that plays an important role in the digestion of food.The organs flowering plants include the leaves,stems,and roots.)

Organs that work closely together form an organ system.

(For example, the esophagus,stomach,and intestines work together during digestion and make up the digestive system.The leaves,stems,and buds of flowering plants make up the shoot system.)

All the organ systems in the body make up the organism,the highest level of organization.

Answer 2

A cell is the smallest structural and functional unit of an organism. A group of similar cells make up a tissue. There are mainly four types of tissues found in the human body. They are:
1. Epithelial tissue
2. Muscular tissue
3. Connective tissue
4. Nervous tissue.

Many similar or different types of tissues for organs.
eg: Heart, lungs, stomach

Many different types of organs together form an organ system
eg: digestive system, circulatory system
