what is cell and tissue? difference between cell and tissue .
Answers
Answer:
The basic unit that constitutes a living organism and facilities life functions is called a cell. All living organisms comprise cells, and millions of microorganisms like bacteria are nothing but a cell capable of fully functioning on its own. Further, for complex multi-cellular organisms like plants and animals, these cells are organized into tissues, organs, and organ systems. Cells are categorized as eukaryotic cells and prokaryotic (primitive) cells based on the presence or absence of the nucleus and other membrane-bound organelles.
Tissues are formed by cells of similar functions being grouped together. The tissues further develop into organs with specific functions. Tissues are hence similar to cells but more organized and specialized to perform a particular function. In plants, there are broadly two types of tissues- meristematic tissues that contain actively dividing cells, and permanent tissues that are differentiated to do specific functions.
What is the Difference Between Cells and Tissue?
Cell
Tissue
They are the basic functional and structural building blocks of a living organism.
They are a product of a well-organized group of cells that perform a particular function.
Both unicellular and multi-cellular organisms are made up of cells.
A unicellular organism doesn't have a tissue-level structure or functioning.
The organelles within a cell have several different functions that sustain the life of the cell.
The central tissue and cell difference is that the cells constitute tissues to perform a specific function.
Functions within a cell include metabolism to generate energy, respiration, reproduction, and growth.
Tissues comprise specialized cells. Therefore, they combine to form an organ to perform a specific function.
An important difference between tissue and cell is that cells can divide through mitosis and meiosis.
Tissues are formed through the regeneration of cells and fibrosis.
The two types of cells are- prokaryotic and eukaryotic cells.
The four types of tissues are- epithelial, muscle, nervous, and connective.
Cells are microscopic.
Tissues are macroscopic.
