Question

Different types of cells have different shapes because
A. They perform different function
B. They contain different types of organelles
C. They are stretched by neighboring cells into distinctive shape
D. They are subjected to different rates of osmosis across their membranes

Answer 1

Hint: Cells are the basic structural and functional unit of life. Each cell is destined to perform different functions. Its different shape and size of cells make it possible for them to perform different functions.

Complete step by step answer:
A branch of biology which deals with the study of the structure and function of the cell is called cell biology. The cell is the basic and fundamental unit of life that collectively forms a tissue. Groups of cells with the same shape and size are clustered together to form a tissue performing a particular function. Different shapes of cells are round, elongated, or spherical. Spindle-shaped cells are long and elongated at the ends. Some cells like neurons are branched. Each cell of eukaryotic and prokaryotic organisms consists of the same cell organelles and each cell performs different functions. The cell size is variable and its length is dependent on the function it performs. The cell membrane encloses the components of the cell and provides shape to the cell of plants and animals. Due to the different functioning of each cell, they have different shapes and sizes. For the proper working of the body, each cell has its own role to play. The different role of cells is carried effectively because of it having different shapes.
So, option A is the correct answer.

Note: Cells are not visible through naked eyes as they are microscopic in size. The smallest size of the cell is found in bacteria and the largest cell is the egg of an ostrich. Cell wall found in plant cells is an extra covering to the cell and is absent in animal cells.
