Mitosis

Science

QuestionAnswer
The process by which organisms make more of their own kind. Reproduction.
Cell division. The way new cells are produced.
What organelle controls cell division? Nucleus.
An orderly set of complex changes in the nucleus, normally involving an exact duplication of the cell. Mitosis.
If the original cell has 46 chromosomes, how many does the daughter cell have after mitotic division? 46.
Chromosomes. Rod-like structures in the nucleus that contain genes.
The production of new organisms without the fusion of the nuclei. Asexual reproduction.
True or False: In asexual reproduction, the new organism develops from a cell of a single parent and has characteristics identical to the cell. True.
Interphase. The in between stage where chromosomes are replicated during the interval between cell divisions.
What are chromosomes made up of? A centromere that connects two identical chromotatids.
Prophase. The nuclear membrane disintegrates, shortened chromosomes and spindle fibers appear at the ends of the cell.
Metaphase. The double stranded chromosomes became attached to the spindle fibers at their centromeres and move to the middle of the cell (central pane/equator).
Anaphase. The centromeres separate and the spindle fibers pull the chromosome pairs apart towards the opposite poles of the cell.
Telophase. The nuclear membrane reappears and forms around each new set of chromosomes, forming two identical nuclei.
Cytokinesis. Cytoplasm divides into two new cells.
Animal cell mitosis. Contains centrioles that make spindle fibers, the cytoplasm is divided by pinching the cell membrane inwards.
Plant cell mitosis. A cell plate is formed to become the new cell wall and split the cells.
Cell division in which the nuclear material and the cytoplasm of the parent cell divide equally and form two daughter cells of the same size. Binary fission.
The parent organism divides into two unequal parts. Budding.
Forms spores, which are small reproductive cells that can give rise to a new organism under favorable conditions. Sporulation.
The development of lost parts or growth of an entire new organism from a part of an organism. Regeneration.
Examples of an organism that goes through sporulation. Bread mold.
Examples of organisms that go through regeneration. Starfish and planarian worm.
Equal nuclear division and equal cytoplasmic division. Binary fission.
Equal nuclear division but unequal cytoplasmic division. Budding.
A type of regeneration that occurs in plants. Vegetative propagation.
Short, underground stem surrounded by thick, fleshy leaves that contain stored food. Bulbs.
Enlarged underground stem with buds and stored food. Tubers.
A horizontal stem with buds that grows along the surface of the ground. Runners.
Thick, horizontal stem containing stored food. Rhizome.
Types of artificial mitosis. Cutting and grafting.
A stem or leaf is placed in soil and a complete new, identical plant develops from it. Cuttings.
The stem of one plant to be propagated is attached to the cut end of another growing plant. Grafting.
