Answer:
It's a form of asexual reproduction!
Development of the offspring happens without fertilization in this type of reproduction.
The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.
Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei
Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are genetically distinct from their parent cell.
Example:
An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!

M. J. Schleiden:
In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)
<h3>
What is cell?</h3>
All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.
His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.
Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.
Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.
His experiment:
Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

Answer:
something that isnt from a living thing. Such as a table falling.
Answer:
A saprophyte is a plant that does not have chlorophyll and gets its food from dead matter, similar to bacteria and fungi (note that fungi are often called saprophytes, which is incorrect, because fungi are not plants).
