Why do bacteria form endospores? O Endospores are formed to increase the surface are of the cell to absorb more essential materials.

O Endospores are formed in response to unfavorable growth conditions in the bacterial environmen O Endospores are formed to produce enzymes to speed up metabolism. Question 56 Which of the following statements correctly describes the normal tonicity conditions for O The animal cell is in a hypotonic solution, and the plant cell is in an isotonic solution. O The animal cell is in an isotonic solution, and the plant cell is in a hypertonic solution.

Structure and Composition of Cell Membrane

Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.

Cell Membrane

The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment. 

Prokaryotes vs Eukaryotes

The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
