Chapter 5 Mitosis is the basis of asexual reproduction
Terms in this set (20)
1.Spindle fibres complete forming. 2. Chromosomes attach to the spindle fibres. 3. Nuclear membrane disappears.
X-shaped chromosomes from a single line at the middle (equator)of the cell.
1.Spindle fibres contract and shorten.2. Chromosome is pulled apart and each sister chromatid moves to opposite poles.
In telophase,a nucleolus forms around the chromosomes at the opposite ends of the dividing cell.
Clones is an identical genetic copy of the parent.
Asexual reproduction is when only one parent is required.And usually happens quick and reproduces large numbers
Special cells in plants divide repeatedly to form structures that will develop into a plant identical to be parent
Usually plant stems or plant roots divide
Spores ate very light in weight and depend on weight or water to carry the spore away from the parent.
If the conditions are right(enough nutrients,water and sun)the spore will begin to grow wherever it lands.
-Purpose is to produce a genetic duplicate of an existing or dead organism
Purpose is to help correct health problems.
Single parent cell replicates its genetic materal and divides into equal parts
Only a few different types of cells so it is reproduction
Organism breaks apart as a result of injury and each fragment them develops into a clone of its parent.
Asexual reproduction is the formation of a new individual that has same genetic information from its parent.
Asexual reproduction occurs in multicellular organisms such as bacteria and in one-celled organisms such as plants.
Sometimes humans help other organisms organisms reproduce asexually to make large numbers of a particular type of organism that has a useful trait.
The stage that makes up most of the cell's life is interphase.During this stage,cells grow and carry out their life functions. In cells that will divide,the nucleus makes a copy of its DNA.
Stem cells are cells that have the potential to become many different types of cells
