ANSWERS:
1. Ans. B
Explanation: Osmosis is the process in which the passage of water goes from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
2. Ans. B
Explanation: Prokaryotes contain a single chromosome and cell division occurs through fission or budding. The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane.3. Ans. B
Explanation: Exocytosis is the process in which the membrane of a vesicle can fuse with the plasma membrane and extrude its contents to the surrounding medium.4. Ans. A
Explanation: Cytoplasm is the jelly-like substance present inside the cell and contains other organelles. It is a thick solution that fills each cell and is enclosed by the cell membrane. Ans. A
Explanation: Blue-green Algae or Cyanobacteria are Prokaryotes. They lack membrane-bound organelles and nuclei.
