Answer:
Explanation: Cytological markers such as the translocated segment and the chromosome knob play a crucial role in various biological research and applied sciences. These markers have proven to be invaluable tools for understanding genetic diversity, evolution, and gene mapping in organisms. The translocated segment, which is an exchange of genetic material between nonhomologous chromosomes, can provide insights into evolutionary relationships between species. By studying translocations, scientists can determine how different species are related and how genetic material has been exchanged or rearranged during evolution. On the other hand, the chromosome knob is a distinguishing structure found on certain chromosomes that serves as a reliable cytological marker for gene mapping and breeding programs. It facilitates the identification of specific genes associated with particular traits or diseases through cytogenetic techniques. Moreover, these cytological markers enable researchers to develop breeding strategies that aim at improving crops' yield, disease resistance, or other desirable qualities by precisely transferring particular chromosomal segments or genes identified by the presence of knobs and translocations. Hence, understanding the significance of cytological markers is vital for both basic scientific discoveries and practical applications in agriculture and medicine.

Explanation:
The microscopic organisms at the base of the marine food chain are known as plankton.
Plankton are mostly microscopic animals and plants found drifting or floating I he ocean or in large bodies of fresh water , consumed as food by almost all aquatic animals.
Plankton which are more plant-like are referred to as phytoplankton, while plankton which more animal - like are referred to as zooplankton. However many plankton species are neither animal nor plant, rather they are organisms belonging to the kingdom Protista.
Examples of phytoplankton include diatoms, coccolithophores and dinoflagellates. These are the most common phytoplankton.
Zooplanktons include jellyfish, Portuguese Man o' War, copepods and isopods.
