Different cells perform different functions within the body.
|
|
|
All cells in the human body are shaped like discs and contain one nucleus.
|
|
|
Environmental factors cannot influence the development of a cell.
|
|
|
The genetic information contained in cells differs between cell types.
|
Detailed explanation-1: -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-2: -They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.
Detailed explanation-3: -Final answer: The statement which is true for cells is a single cell can perform all the functions in a unicellular organism.
Detailed explanation-4: -Synthesis of proteins: These proteins are synthesized in the ribosomes borne on the rough endoplasmic reticulum and are crucial for all cellular activities. This is the primary function of all cells.
