Eukaryotic Cell:Internal Structure
Zairra Williams
The Nucleus : The Control Center
The nucleus is a compact sphere that is the most prominent organelle of eukaryotic cells. Separated from the cell cytoplasm by an external boundary called nuclear envelope. The envelope has a unique architecture. Its composed of two parallel membranes separated by a narrow space.
Mitochondria: Enegry Generators of The Cell
The cell's control center none of the cellular activities it commands could proceed without a constant supply of energy , the bulk of which is generated in most eukaryotes by mitochondria.
Ribosomes
In a electron micrograph of a eukaryotic cell, ribosomes are numerous tiny particles that give dotted appearance to the cytoplasm. Ribosomes are distributed throughout the cell.
Nucleus
The nucleus is a compact sphere that is the most prominent organelle of eukaryotic cells. It is separated from the cell ctyoplasm by an external boundary called a nuclear envelope.
Golgi Apparatus
Is also called , the Golgi complex,or Golgi body.In the site in the cell which proteins are modified and then sent to their final destinations.
Nucleus, Endoplasmic Reticulum, and Golgi Apparatus: Nature's Assembly Line
Network ribosomes which originate in the nucleus , and the rough endoplasmic reticulum , which is continuously connected with the nuclear envelope, as well as the smooth endoplasmic reticulum and the Golgi apparatus .
Mitochondria: Energy generators of the cell
Supplies the nucleus with a constant amount of energy. The bulk of which is generated in most eukaryotes by mitochondria.
Choroplast: Photosynthesis Machines
Chloroplast are found in the alge of plants, and the y are capable or converting the energy from the sun into food. This process makes it the primary producer of organic nutrients on eatrh
Ribosomes: Proteins synthesizers
They are numerous tiny particles found in the cytoplasm. They are distributed in the cell: some are scattered freely in the cytoplasm and cytoskeleton. Others are attached to the rough endoplasmic reticulum as previously described.
Cytoskeleton:A Support Network
cytoplasm is crisscrossed by a flexible framework of molecules called the cytoskeleton. It apers to have several functions , such as an anchoring organelles, moving RNA and vesicles, and permitting shape changes and movnement in some cells.
Survey of Eukaryotic Microorganism
This contain a general survey of the principle eukaryotic microorganisms--fungi, alge, protozoa, and parasitic worms while also introducing elements of their structure, life, history, classification, identification, and importance.
