Somatic cells are all the cells that make up an organism, including the organ, muscle, fat, bone, and skin cells. The only exceptions are the egg and sperm cells, also called germ cells, which are involved in sexual reproduction. Although somatic cells differ greatly in their form and func...
Can meiosis occur in somatic cells? How does trisomy 21 occur during meiosis? Which part of meiosis is the same as mitosis? What is the starting cell of meiosis called? What are the reproductive cells produced by meiosis called? During which of these stages of meiosis do homologous chromosomes...
Which human cells never have 23 pairs of chromosomes? What chromosomes exist in somatic cells? What do chromosomes do in meiosis but not in mitosis? What are homologous chromosomes? What does each chromosome determine? How many chromosomes does each daughter cell have? How many sex chromosomes do...
The short answer is that stem cells are undifferentiated cells with power to make other kinds of cells. Most cells cannot do that as they can only make more of themselves. What this means is that stem cells can be used to make specialized cells. These include neurons, heart cells, and mo...
Stem cells: The body's master cells Stem cells are a special type of cells that have two important properties. They are able to make more cells like themselves. That is, they self-renew. And they can become other cells that do different things in a process known as differentiation. Stem...
When a diploid cell undergoes meiosis, it forms four new haploid cells. A haploid cell is a cell that contains only half of the genetic information of... Learn more about this topic: Meiosis | Overview, Function & Steps from Chapter 5/ Lesson 5 ...
In humans and many other animals, some cells contribute to what is called thenervous system, which is responsible for communication of the organism both internally and with the outside environment. The cells that make up the majority of this system are calledneurons, or simply nerve cells. ...
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...
In plant cells, are the cell wall and cell membrane the same? Are gametophytes made up of somatic cells? If so, can they pass on a mutation? What mechanism and immune cell in specific does the body use to eventually bring the HIV virus back down to low levels?
Mitosis is considered an “equational” form of cell division — it occurs in cells that do not produce gametes (e.g., somatic cells). During mitosis, a cell divides once to produce two daughter cells with genetic material identical to that of the original parent cell and to each other. ...
