Define the term cell & tissue?

Answer 1

cell= the basic biological functional unit
it is either prokaryotic cell or eukaryotic cell.
prokaryotic have no nucleus but only have a dense region containing the cell genetic material called the nucleiod while eukaryotic cell have a membrane bound nucleus. examples of eukaryotic cell: fungi,animals, plants and prototist cell.

tissue= is a group of specialised cell which have the same funtion and struture and also the same embyonic orgin.

Answer 2

Define Tissue

Answer 3

Tissue Definition

Answer 4

A cell is the smallest unit of construction and working in living bodies.
A tissue is a group of cells performing a similar task.

RE:

Answer 6

Cell is the basic and stuctural unit of life. Tissue is group of cells which has same origine and same functin.

Answer 7

Cell is the structural and functional unit of all living organisms.

Tissue: It is group of cells, which are identical in structure and function present in an multicellular organism. that means tissue is a group of cells sharing common function. Eg:parenchyma,sclerenchyma.

Answer 8

cell is the basic unit of life
tissue can be defined as the combination of cells

Answer 9

Cell : It is nthe basic structural and functional unit of life .
Tissue : A group of similar cells which work in a coordinated manner to perform a specific function or process .

Answer 10

in biology, the basic unit of which all living things are composed. As thesmallest units retaining the fundamental properties of life, cells are the “atoms” of the living world. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells, by differentiating in order to acquire specialized functions and cooperating with other specialized cells, become the building blocks oflarge multicellular organisms as complex as the human being. Although they are much larger than atoms, these building blocks are still very small. The smallest known cells are a group of tiny bacteria called mycoplasmas; some of these single-celled organisms are spheres about 0.3 micrometre in diameter, with a total mass of 10-14 gram—equal to that of 8,000,000,000 hydrogen atoms. Human cells typically have a mass 400,000 times larger, but even they are only about 20 micrometres across. It would require a sheet of about 10,000 human cells to cover the head of a pin, and each human being is composed of more than 75,000,000,000,000 cells.


in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.

TISSUE:
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism's response to its environment.
