In the last chapter, you studied cell – as the fundamental unit of life. In this
chapter, you’ll study tissues and their types. Tissues are a group of cells that are
similar in structure or act together to perform a particular function. Our body
follows a certain level of organisation. In single cellular organisms like an amoeba,
there is only one cell that performs all the functions. However, multi-cellular
organisms like humans have a very complex structure, where cells are grouped
together to perform efficiently such as blood, bones, muscles, etc.
These tissues group together to form organs, and organs group together to form
the organ system. It is interesting to know that plants and animals have different
types of tissues that perform specific functions. In NCERT Solutions for Class 9
