Answer 1

Multicellular organisms are organisms consisting of more than one cell, and having differentiated cells that perform specialized functions. Most life that can be seen with the naked eye is multicellular, as are all members of the kingdoms Plantae and Animalia (except for specialized organisms such as Myxozoans in the case of the latter).

examples are: Fungi, plants, and animals

Answer 2

Many organisms including man are multicellular (multi = many, multicellular = made up of many cells) organisms.

The more complex multicellular organisms cope with the problem of being vulnerable to changes in the environment by surrounding their individual cells with fluid that is separated from the environment by a barrier such as the skin.

This fluid is now the immediate environment of the cells of such multicellular organisms and is called the extracellular fluid. The extracellular fluid acts in the same way as the pond water does for the amoeba. The extracellular fluid is sometimes known as the internal environment because it is within the organism.
