In plants mitosis takes place throughout life ingrowing regions called the meristems. Where does mitosis occur in humans? Mitosis occurs only ineukaryotic cells. Prokaryotic cells, which lack a nucleus, divide by a different process called binary fission. Mitosis varies between organisms. Where does...
During MITOSIS, the parent,diploid(2n), cell is divided to create two identical, diploid (2n), daughter cells. This occurs by undergoing DNA replication (in S phase during interphase) where the monovalent chromosome is duplicated so that it will have two DNA strands that are replicas of each...
Where do mitosis and meiosis occur in animal and plants? View Solution [A]: Meiosis II is not mitosis. [R]: Meiosis II occurs in cell with haploid chromosomes View Solution Assertion: Endomitosis does not cause karyokinesis or cytokinesis. Reason : In endomitosis, mitosis occurs within ...
Plants are multicellular organisms that require cell division in the form of mitosis in order to grow and to replace old cells. The goal of mitosis is to produce two daughter cells that are genetically identical to their single parent cell....
The meiotic process, considered an alternative of the mitotic process when it occurs in somatic cultured plant cells, is discussed in detail, taking into account the importance, for evolutionary purposes, of this source of genetic variation. A new concept of cell totipotency is formulated, as ...
Mitosis occurs in somatic cells, which are all cells of the body except for germ cells that undergo meiosis. 12 What mechanisms in meiosis increase genetic variation? Crossing over (the exchange of genetic material between homologous chromosomes) and independent assortment (random distribution of chrom...
The most rapid rate of mitosis occurs during periods of growth, such as during the zygote, embryo and infant stages in humans and after periods of inactivity in plants. Mitosis Versus Meiosis Two types of cell division are mitosis and meiosis. In meiosis, a cell splits to form new cells ...
Using Figures 1–4, diagram the phases of mitosis and in the space provided to the right, describe the events of each phase using a chromosome number of 6 (2n = 6). Figure 1. Prophase Figure 2. Metaphase Figure 3. Anaphase Figure 4. Telophase Introduction In plants, cell division cell...
Plants use a similar process with a few differences. For example, although a plant cell creates a mitotic spindle and has a centrosome, it lacks centrioles. The other major difference in plants is the way in which cytokinesis occurs. In animal cells, the plasma membrane pinches in along the...
