What is reproductive cells that develop into new individuals by repeated mitosis?
In animals, fertilization of the ovum by a sperm results in the formation of a diploid zygote that develops by repeated mitotic divisions into a diploid adult. Plants have two multicellular life-cycle phases, resulting in an alternation of generations.
What is it called when part of a plant is separated from the parent and grows into a new identical plant?
Asexual propagation involves taking a part of one parent plant and causing it to regenerate itself into a new plant. The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or leaves.
Do reproductive cells undergo mitosis?
Mitosis is responsible for reproducing somatic cells and meiosis is responsible for reproducing germ cells.
How vegetative propagation occurs in leaf explain?
Explanation: This is a form of asexual reproduction in which new plants grow from the buds growing on the margin of the leaves. These buds are reproductive in nature and when they fall on the ground they germinate and form a new plant. Begonia and Bryophyllum are examples of vegetative propagation by leaves.
When an organism breaks into a number of parts and each part develop into an individual it is called?
Fragmentation is the process in which the body of an organism breaks up into two or more pieces, which on maturing grows to form a completely new organism.
What structures do plants use for vegetative reproduction what grows from leaves stems and roots?
Natural vegetative propagation occurs when an axillary bud grows into a lateral shoot and develops its own roots (also known as adventitious roots). Plant structures allowing natural vegetative propagation include bulbs, rhizomes, stolons and tubers.
What type of reproduction is exhibited by the plants in the story?
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen.
How many cells are formed when a single cell divides?
A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process “cell division” and “cell reproduction,” because new cells are formed when old cells divide.
Which type of cell division is good for basic growth?
This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into four cells that have half the number of chromosomes. Reducing the number of chromosomes by half is important for sexual reproduction and provides for genetic diversity. Mitosis is how somatic — or non-reproductive cells — divide.
Why are daughter cells from mitosis called diploid?
The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes. Since the daughter cells have exact copies of their parent cell’s DNA, no genetic diversity is created through mitosis in normal healthy cells. Mitosis cell division creates two genetically identical daughter diploid cells.
What determines what the cell will become?
The cell has unique DNA that determines what the cell will become. Q. The diagram shows the process of cell specialization from a single stem cell. Which of the following statements is true about the process of specialization. Q. Which is NOT an example of cell differentiation?
