Tissues are spread evenly throughout the body and have comparable functions. Organs in plants and animals are made up of organised tissues which perform specific functions. These are composed of cells of the same type. These are also composed of the same tissues.
Tissues
Tissue is a terminology used to define a collection of cells with similar shape and function. In the cell and organ system hierarchy, they represent a cellular organisational level. Tissues are composed of specialised cells which perform certain functions. Organs are then formed by combining functional groups of tissues.
Tissue is a group of cells with similar characteristics which work together to form unity. The intercellular matrix is a nonliving substance that fills the spaces between cells, that can be abundant or few. The intercellular matrix, that is unique to each tissue and provides its individual characteristics, may contain special substances like salts and fibres. Each is developed with a specific function in mind.
Organs
A collection of tissues in a living organism which have been developed to accomplish a certain function is referred to as an organ in biology. Organs in higher animals are organised into organ systems; for instance, the digestive system includes the oesophagus, stomach, and liver.
The integumentary, skeletal, muscular, nervous, endocrine (hormonal), digestive, respiratory, circulatory, excretory, and reproductive organ systems are commonly found in more sophisticated species. These systems emerge gradually in lesser species, progressively increasing in complexity and functional specialisation as they progress to larger creatures. The basic organs of plants include the stem, root, and leaf, that all contribute to sustain the plant, as well as the reproductive organs (e.g., flowers, seed, and spores). These organs, like those in animals, are in charge of the organism’s basic life-sustaining processes.

4 tissue types
Connective Tissue
Connective tissues, like organs, let the creature’s body maintain up with the type of creature it is. These tissues also provide inner support to the body. They aid in the fusion of the organs.
They also work to prevent germs from entering the body. These tissues also aid in the transfer of vitamins, chemicals, gases, and waste from one part of the body to the next.
There are various types of connective tissues, such as bone tendons, ligaments, and ligaments. Stringy, liquid, and skeletal connective tissue are the three types of connective tissue.
Muscle Tissue
Muscle tissues, as the names suggest, aid in body movement. They produce motion and force for bodily movement and also internal organ movement.
Skeletal, cardiac, and visceral or smooth muscle tissue are the three types of muscle tissue. Muscle tissues play an important function in a variety of physical motions, including running, lifting, jumping, picking, and so on.
They aid in the preservation of the body’s position and postures. Both voluntary and involuntary motions are linked to them.
Nervous Tissue
They are the key tissue components of the central nervous system’s brain and spinal cord. The peripheral nervous system consists of the cranial nerves and spinal nerves, which are generated by neural tissue.
The internal communication network of the body is controlled by this tissue. In the information processing process, it is critical.
It’s also responsible for responding to stimuli and relaying data within the body. It helps an organism’s emotions, mental capacities, and memory to be controlled.
Epithelial Tissue
They are composed of cells which line the organ surfaces and cover the external parts of human organs like the skin, the reproductive tract, the airways, and the digestive tract’s inner lining.
Epithelial tissues play an important part in an organism’s body. Sensory reception, filtration, and a range of other metabolic functions are all performed by them. It also helps with the dispersion and secretion of a wide range of chemicals.
Epithelial tissues protect internal organs as well. These tissues secrete a variety of enzymes, mucus, hormones, and other things.
Organ systems
An organ system is a biological system made up of a collection of organs which perform one or more activities together. Each organ in a plant or animal’s body serves a specific purpose and is made up of different tissues.
Human beings have 11 separate organ systems that make up the foundation of human anatomy and physiology. The 11 organ systems include the respiratory, digestive, and excretory systems, circulatory and urinary systems, integumentary, skeletal, and muscular systems, endocrine, lymphatic, neurological, and reproductive systems.
On the other hand, there are two primary organ systems in plants. A shoot system and a root system are two separate organ systems in vascular plants.
Conclusion
The distinction between a tissue and an organ is undeniably fundamental and deserving of further consideration. Cells make up all living things, and tissues are a collection of cells that join to form organs, which then form an organ system. The tissues conduct simpler functions than the organs, which accomplish the body’s more sophisticated activities. Second, the size of an organ is larger than the size of the tissues, requiring more energy to carry out the functions.
