An Introduction Of Cell Biology
Introduction to Cell Biology
A Cell is the smallest structural and functional unit of an organism and consists of cytoplasm and a nucleus enclosed in a membrane
A Prokaryotic Cell are cells without a membrane–bound nucleus. An example of a prokaryotic cell is bacteria.
A Eukaryotic Cell does have a membrane–bound nucleus, making it different from a Prokaryotic Cell. The Nucleus contains genetic material and
is surrounded by a nuclear envelope. An example is an animal cell.
Both types of cells contain organelles, each with a specific function. Plant and animals cells both contain a nucleus, cell membrane, cytoplasm and
mitochondria. What defines the two cells is the plant cell also contains a rigid cell wall, a permanent vacuole and chloroplasts. The Nucleus
contains genetic material and controls how the cell operates. The Cell surface membrane, or plasma, surrounds the cell and controls what enters
and leaves. Membranes are said to divide up the cytoplasm of eukaryotic cells. The Cytoskeleton, which is made up of microtubules and
microfilaments, moves the cytoplasm during cell migrations. Mitochondria is where aerobic respiration is performed. Protein synthesis happens in
the Ribosomes. In terms of the plant cell, the Rigid Cell Wall strengthens the cell and helps maintain the structure. The Chloroplasts contain
chlorophyll, which absorbs light for a plant to perform photosynthesis. The Permanent Vacuole is filled with sap and keeps the cell turgid.
