Cellulose and amylose are both important organic molecules produced by plants, but cellulose is mainly used to serve a structural role. Amylose is used to store sugar that is produced via photosynthesis.Know More
Cellulose is the principle component of a distinctive feature of plant cells, the cell wall. Cell walls keep plant cells stiff and allow a plant to grow tall and have access to sunlight even in crowded conditions like a forest floor. Cellulose bound in another organic molecule called ligin is what makes wood from trees so strong.
Amylose is a principle component of starch. It makes up about 30 percent of starch by weight. It has an extended molecular structure that tends to bind water, making it excellent for forming gels. The other component of starch, amylopectin, is also absorbent, but when it absorbs water it tends to swell rather than thicken the solution. Both molecules are used to store sugar inside plant vacuoles for when sunlight is not as readily available.
Both cellulose and amylose are complex carbohydrates. In cellulose, the carbohydrate chains are arranged in a criss-cross mesh of long molecules like beams inside a steel building. Amylose forms long unbranched chains that tend to twist into stiff helixes. Both molecules can be used as food sources, but humans lack the proper enzymes to break down cellulose. Other animals, including termites, are able to consume the cellulose carbohydrate.Learn more about Cells
One main difference between protists and bacteria is that protists are eukaryotic organisms, while bacteria are prokaryotes. Another difference is that protists belong to the kingdom Protista, while bacteria are members of the Monera kingdom. Bacteria are uni-cellular organisms that do not contain organelles like a nucleus or chloroplasts.Full Answer >
Necrosis and apoptosis are differentiated by their causes, with necrosis being the accidental result of interactions with pathogens and apoptosis being the product of a programmed cell mechanism. These are the two major types of cell death in living, multicellular organisms. Despite this customary dichotomy, research indicates that the distinction between these two types of cell death are not as clear as was once thought.Full Answer >
Differences between plant and animal cell mitosis include the presence of mid bodies, the role microfilaments play in cytokinesis and whether centrosome occurs. Initially, animal cell mitosis occurs in the epithelia and bone marrow, while plant cell mitosis is found in meristems.Full Answer >
The steps of meiosis are the same for both males and females, but the end result is different because the female produces an egg, while the male produces sperm. The process is also named differently in the sexes. The stage of meiosis in a female is called oogenesis, and in a male it is called spermatogenesis.Full Answer >
