The following points highlight the three methods of Sexual Reproduction (Para Sexuality) in Bacteria. The methods are: 1. Conjugation 2. Transformation 3. Transduction. Method # 1. Conjugation: It was first discovered in Escherichia coli by Lederberg and Tatum (1946). They found that two different types of auxotroph (nutritional mutants) grown together on minimal medium produced an occasional prototroph (wild type). [...]
The following points highlight the five modes of locomotion in Protists. The modes are: 1. Pseudopodial Locomotion 2. Flagellar Locomotion 3. Ciliary Locomotion 4. Wriggling Locomotion 5. Locomotion by Mucilage Propulsion. Mode # 1. Pseudopodial Locomotion: It is slow creeping type of locomotion which is performed with the help of protoplasmic outgrowths called pseudopodia. Pseudopodial locomotion occurs in sarcodines and [...]
The upcoming discussion will update you about the difference between life cycle with Zygotic and Gametic Meiosis. Difference # Life Cycle of Zygotic Meiosis: 1. Zygote is the only diploid structure in the life cycle. 2. The dominant individual in the life cycle is haploid hence the life cycle is haplontic. 3. Meiosis takes place at the time of zygote [...]
