Which cells in your body are haploid? What process produces those cells? In which stage does the diploid nucleus divides into four haploid nuclei? Which cells do not divide by mitosis? Which cells undergo meiosis? What part of meiosis is also known as equational division?
The stages of meiosis and how they differ from the stages of mitosis. Explain briefly. Which phase of meiosis is very similar to mitosis? (a) What types of cells does meiosis make? (b) How about mitosis? Which phases are exactly the same for both the cell cycle and meiosis?
Most cells of the body aresomatic cells, meaning that they do not play a role in reproduction. Almost all of these cells undergo mitosis, supplying new cells for growth, tissue repair and other day-to-day needs. On the other hand, gametes, also called germ cells, arise from a process o...
Meiosis introduces genetic diversity through crossing over and independent assortment, leading to gametes that are genetically distinct from each other and from the parent cells. 12 Can mitosis occur in all types of cells? Mitosis occurs in somatic cells, which are all cells of the body except fo...
This cell life cycle occurs throughout your body and its trillions of cells. Including in your brain. But what if there was some way to slow down this programmed cell death? Turns out there is. And it’s called L-Carnosine. Researchers at Sydney Laboratory in Australia found that l-carnos...
Somatic cells—that is, the cells in your body that aren’t sex cells—do this via a process called mitosis. New sex cells, or gametes, are produced via a different process, called meiosis. Today, we’re going to talk about both of these. How are they different? How are they similar...
Organelles are small subcellular structures located in the cytoplasm of eukaryotic and prokaryotic cells, and in more complex eukaryotic cells, organelles are often enclosed by their own membrane. Each organelle performs a specialised function for that cell, much like an organ does for the body. ...

What are rare mesothelial cells? Mesothelioma is arare form of cancerthat affects the cells that make up the mesothelium. The mesothelium is the lining or membrane that covers and protects various internal organs of the body. The mesothelium is composed of two layers of specialized cells know...
Morphallaxis, on the other hand, involves direct migration of pre-existing adult stem cells or progenitor cells to the wound, which then differentiate to functional cells and tissues. A typical example of morphallaxis is the body regeneration of the Cnidarian hydra that is able to develop into...
