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 [...]

The following points highlight the seven modes of nutrition in protists. The modes are: 1. Photosynthetic 2. Holozoic or Zoo-Trophic 3. Saprobic or Saprotrophic 4. Parasitic 5. Mixotrophic 6. Symbiotic 7. Pinocytosis. Modes of Nutrition # 1. Photosynthetic (Holophytic): In this mode, the organisms prepare their food from CO2 and water by utilizing sunlight with the help of photosynthetic pigments [...]
