Explanation:
Actually, two organelles transport protein in a eukaryotic cell (multicellular organisms): (rough) Endoplasmic Recticulum and Golgi Apparatus.
The (rough) endoplasmic recticulum transport the newly synthesized proteins to the golgi apparatus from where they are transported to the various regions of the cell or outside the cell. Smooth endoplasmic recticulum is not associated with protein transport.
Proteins, carrying a signaling sequence, are transported from the endoplasmic recticulum, packaged into vesicles, to the golgi apparatus (or golgi complex or golgi bodies). These proteins are modified by enzymatic reactions as they move through the golgi apparatus. After processing, these proteins are either excreted from the cell or are sent to various locations within the cell.
It is difficult to pinpoint the location of these organelles within the cell as locations are different for mammals, plants, yeasts, etc. Generally, the golgi apparatus is found adjacent to the endoplasmic recticulum, which in turn is found throughout the cell but has a higher density near the nucleus.
Answer:
Why is it important to learn about stem cells and stem cell research?
Researchers hope stem cell studies can help to: Increase understanding of how diseases occur. By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers may better understand how diseases and conditions develop.
How does stem cell research affect society?
Research with embryonic stem cells may lead to new, more effective treatments for serious human ailments and alleviate the suffering of thousands of people. Diseases such as juvenile diabetes, Parkinson's disease, heart failure and spinal cord injuries are examples.
The surface area to volume ratio of the cell decreases.
This decrease is due to the fact that the volume of the cell increases at a greater rate than the surface surrounding the cell, the cell membrane, increases. This change is also visible when we are blowing up a balloon.
When considering the cell division, the ratio remains roughly the same. It is advantageous for the cell to preserve its surface area to volume ratio, since a higher ratio means that substances are able to diffuse into and out of the cell at a fairly higher rate.
Answer:
Flagella is a locomotary organ of bacteria whereas cell wall is the outermost covering of plant cell
