Vesicles transport materials within a cell. Vesicles are constantly forming, membrane-wrapped containers that transport things like protein through a cell.Know More
Vesicles that are artificially prepared are called liposomes. Naturally prepared vesicles are those made during exocytosis, endocytosis and phagocytosis. The membrane that encloses a vesicle is similar to the plasma membrane, and plasma membranes and vesicles can fuse together, making it possible to release the contents of the vesicle outside the cell.
Vesicles have various job functions. They aid in metabolism and enzyme storage and help control the balance inside and outside a cell. When vesicles malfunction, sometimes serious or fatal conditions may occur like diabetes and epilepsy.Learn more in Cells
In an embryo, one cell becomes a brain cell and another a skin cell through the process called cell differentiation, which involves changes in gene expression. The genome stays the same in each specialized cell, while each cell has a different structure and functions.Full Answer >
A cell spends most of its life in the interphase stage where it is able to grow, create DNA and obtain nutrients in preparation for cell division. Interphase is not a part of meiosis or mitosis, but rather a stage that lets the cell perform required functions for reproduction.Full Answer >
A cell without a nucleus is classified as a prokaryotic cell. The genetic material of prokaryotic cells is free inside the cytoplasm. Prokaryotic cells do not have a need for compartmentalization, unlike more complex cells.Full Answer >
Cellular division is important because without these changes, most organisms would die. All life begins and thrives through cellular processes, and cell division is the process of development and transformation. According to HowStuffWorks.com, “In multicellular organisms, cell division is responsible for the growth of the organism and the replacement of old or worn-out cells.”Full Answer >
