EVERYDAY SCIENCE

Detailed explanation-1: -Is the statement true or false? Because they share similar structures, cells all carry the same function. False.

Detailed explanation-2: -Although all living cells have certain things in common-such as a plasma membrane and cytoplasm-different types of cells, even within the same organism, may have their own unique structures and functions. Cells with different functions generally have different shapes that suit them for their particular job.

Detailed explanation-3: -Cells of various types have different functions because cell structure and function are closely related. It is apparent that a cell that is very thin is not well suited for a protective function. Bone cells do not have an appropriate structure for nerve impulse conduction.

Detailed explanation-4: -A tissue is a group of similar cells performing similar functions. Each tissue has a specific function.

Detailed explanation-5: -Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs.
