Question
1. In the hierarchy of structural organization in living systems, a tissue
(a) is a collection of distinctively different types of cells that work cooperatively to accomplish a specific task.
(b) is a collection of very similar (or identical cells) cells that have differentiated for a specific purpose.
(c) is a collection of membrane-bound structures that collectively form the structure of a cell.
(d) is a collection of monomer units that are linked to form a single covalently-bound molecule.
(e) can refer to any level of structural organization that has a defined function or purpose.

Explanation / Answer
1. B
A tissue is a collection of very similar or identical cells grouped together to perform a particular function.
Eg- nerve tissue, xylem tissue etc.
2. A
An organ is a collection of two or more different types of tissues. Eg- heart , it contains different tissues specific to perform different different tasks.
