Endoplasm and ectoplasm are names for the inner and outer portions of an amoeba’s cytoplasm. Ectoplasm is the clear outer cytoplasmic layer of an amoeba. Endoplasm, on the other hand, is the inner granule-rich cytoplasm of the amoeba.Know More
An amoeba is a single cell microorganism made up of a nucleus and cytoplasm. Its ectoplasm is a clear gel, while the endoplasm is more fluid or watery and houses the majority of the cell’s granules and minute structures. The endoplasm makes up the bulk of the cell.
Endoplasm helps the amoeba with locomotion or movement. Since amoeba move by flowing its cytoplasm over surfaces, flowing the endoplasm in different directions moves the cell along. The ectoplasm steers the direction of the cell by extending itself into a pseudopodium, a gel-like ectoplasmic tube. The endoplasm then moves the cell by flowing into the pseudopodium. When all of the endoplasm flows into the pseudopodium, the extended ectoplasm, the amoeba advances itself into a new position.
The ectoplasm also is responsible for changing the direction of the pseudopodium. When the alkalinity and acidity of the water changes, the location of the pseudopodium changes. Slight changes in the alkalinity or acidity impedes movement or causes the cytoplasm to start flowing. The endoplasm is responsible for regulating the concentration of water in the cell. Since amoeba have a partial membrane, the endoplasm easily absorbs and releases excess water.Learn more in Biology
The main difference between zooplankton and phytoplankton is that phytoplankton has the ability to manufacture its own food through photosynthesis or chemosynthesis. Zooplanktons are incapable of making their own food. Zooplanktons are animal planktons,while phytoplanktons are planktons that are capable of carrying out photosynthesis.Full Answer >
Bacteria and protozoa are very distantly related, with bacteria classified as prokaryotes and protists as eukaryotes. This means that protozoa are more closely related to humans than either is to bacteria. The two organisms are structurally distinct. Bacterial cells lack a nucleus, and protozoa contain organelles, such as mitochondria.Full Answer >
Although they are both billfish, marlins belong to the family Istiophoridae, while swordfish are the only members of the family Xiphiidae. Visually, the biggest difference is that marlins have a ridge on their back while swordfish have a single dorsal fin.Full Answer >
Anabolism is a process in which the liver creates new proteins from digested nutrients, while catabolism involves the breaking down of proteins into essential amino acids. Both are vital to the body's metabolism and maintaining healthy cell function.Full Answer >
