The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
- Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells.
- The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

Steps involved in Mendel’s experiment of garden pea plants include
A. Derivation of pure breeds as parent plants.
B. Emasculation of plants
C. Bagging of plants.
D. Artificial pollination of the plants.
E. Detailed study of the plant characteristics to statistically study the results.
<h3><u>Explanation:</u></h3>
Gregor Johann Mendel was a very famous monk who experimented with the pea plants to find out the reason behind the inheritance of the characters of the plants. As he experimented with plants having pure character, he led the plants to self pollinate themselves for about 3 to 4 generations to take out only the pure breeding traits.
As he got them, he planted them and emasculated the flowers to prevent the self pollination. He then bagged the flowers to prevent unwanted pollination. He then artificially pollinated the flowers with desired pollens only.
At the end, he studied the phenotypic characteristics of the plants in a very detailed manner to get the best possible results. He also took around 1000 pea plants to get the most error free results.
