What is are organs and tissue?

Answer 1

Amino acids are the building blocks of cells. Cells are the building blocks for tissues; cells specialize into specific types of tissues. Tissues built of specialized cells form organs. Single or multiple organs make organ systems. All of the organ systems make up the organism, the human body in this case.

Cells are the smallest but most powerful unit in the body. Nutrients and oxygen pass through the cell membrane, producing energy and body heat. Cells have machinery to fight infection. Cells also reproduce to repair injuries or diseases, if they can.

Cells specialize into groups of tissues. Specialized tissues have usually one function.

Tissues are grouped by function into body organs. Organs are entirely specialized for a certain function.

Organs are grouped into organ systems. Each organ system has a separate function.

Organ Systems make up the body, or the organism.

Answer 2

Tissues- group of cells that perform a specific function(ex. muscle tissue)

Organs- a group of tissues(ex. stomach)

Organ system- a group of organs(ex. digestive system)

Answer 3

cells are the smallest structural unit of living matter capable of functioning independently.

tissues are an integrated group of cells with a common structure and function.

organs are a collection of tissues which performs a particular function or set of functions in an animal's body.

Short: Cells make up tissue in all living things, tissues make up organs, and organs help organisms perform specific tasks.

Answer 4

Organs are a number of tissues working together, and systems are a number of organs working together such as the curculatory system that moves blood around the body to transport nutreints to the cells and oxygen.
