Answer:
interphase. period of the cell cycle between cell divisions.
Mitosis. cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
cytokinesis. division of the cytoplasm during cell division.
Explanation:
The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.[1] In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.
Answer:
when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake.
Explanation:
Answer:
Vegetative propagation is the process of multiplication in which a portion of fragment of plant body functions as propagate and develops into a new individual.
Explanation:
- Asexual or vegetative propagation of plant is that form of plant propagation in which the new individual arises from any vegetative part of the parent and possesses exactly the same characteristic of the parent plant.
- Vegetative propagation can be carried out through roots as in <em>Dalbergia sissoo</em> (Shisham) ; <em>Psidium guajava</em> (Guava) etc; through stems as in <em>Solanum tuberosum</em> (potato) ; through leaves as in<em> Bryophyllum</em>.
- Plants can be propagated artificially by following natural principle.
- Some artificial methods of vegetative propagation include, Cutting, grafting, budding etc.
