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.
I have a biology question:
prokaryotic and eukaryotic cells BOTH have:
a. An endoplasmic reticulum
b. Membrane bound nuclei
c. A cell membrane and ribosomes
d. Circular chromosomes
match each organelle to its function
lysosome Contains hydrolytic enzymes
mitochondria Site of ATP synthesis in eukaryotic cells
round endoplasmic reticulum Manufactures new membrane and transports proteins
Golgi apparatus Modifies and packages cell secretions into vesicles for export
peroxisome. In plant and animal cells detoxifies hydrogen peroxide
Introduction
Inside cells, organelles are specialised structures that carry out a variety of tasks. Literally, the phrase refers to "tiny organs." Organelles provide specialised functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
