Question

what is tissue level of organisation

Answer 1

The human body has many levels of structural organization: atoms, cells, tissues, organs, and organ system. The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function.

Answer 2

In biology, tissue is a cellular 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.
