Cell Theory - Assignment ExampleThe paper describes all the peculiarities of the cubicle theory. A cell organelle is the part of a cell that has a specific function. Organelles be unremarkably located inside the cytoplasm of a living cell, and are typically envelop in a membrane called plasma membrane. They are called organelles because their importance to a cell is analogous to the importance of organs of to a body. Both prokaryotes and eukaryotes have cell organelles however, there are some important differences between the two. The organelles in procaryotic cells are not organized or enclosed in plasma membranes. Major cell organelles acknowledge chloroplasts, endoplasmic reticulum, golgi apparatus, mitochondria, nucleus and vacuoles. Chloroplasts have double membranes as wholesome as their own DNA, and perform photosynthesis. They are fork up in plants and some algae. Endoplasmic reticulum (ER) has a hit membrane and is responsible for transport as strong as synthesis of proteins. It is of two types rough ER, whose clear appears to be rough because of the presence of ribosomes, and smooth ER, whose get up appears to be smooth. Golgi apparatus is also singe-membraned and is responsible for protein sorting and modification.... Both prokaryotes and eukaryotes have cell organelles however, there are some important differences between the two. The organelles in prokaryotic cells are not organized or enclosed in plasma membranes. Major cell organelles include chloroplasts, endoplasmic reticulum, golgi apparatus, mitochondria, nucleus and vacuoles. Chloroplasts have double membranes as well as their own DNA, and perform photosynthesis. They are present in plants and some algae. Endoplasmic reticulum (ER) has a single membrane and is responsible for transport as well as synthesis of proteins. It is of two types rough ER, whose surface appears to be rough because of the presence of ribosomes, and smooth ER, whose surface appears to be smooth. Golgi appa ratus is also singe-membraned and is responsible for protein sorting and modification. The mitochondrion is also called as the powerhouse of the cell because it is responsible for energy production, and like chloroplasts, it also has a double membrane and its own DNA. The nucleus has both Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) and is responsible for maintenance and strait-laced distribution of DNA during cell division. Vacuoles function as storage reservoirs of the cell. Minor organelles of the cell include autophagosomes that stash away material from the cytoplasm for degradation, centrioles that enable cell division, ribosomes that help in the production of proteins, lysosomes that are responsible for process or breakdown of large molecules into simpler ones, nucleolus that produces ribosomes, and vesicles that function as material transporters in the cell. Many other organelles exist based on the type of organism.
