Question
Which of the following is absent in a prokaryotic cell?
- Cell membrane
- Nucleus
- Cytoplasm
- Genetic material
Hint:
Prokaryotes are creatures without a nucleus or other organelles in their cells.
The correct answer is: Nucleus
- A nucleus, which is where DNA and RNA are kept in eukaryotic cells, is absent from prokaryotic cells.
- They do, however, have a cell wall that gives them form and shields them from their surroundings.
- Proteins are created by both free and fixed ribosomes.

Which of the following organelle stores water, food, and waste?
An organelle is a subcellular structure that functions in the cell similarly to how an organ does in the body. Among the more significant cell organelles are the nuclei, which house genetic material, and the mitochondria, which generate chemical energy. And the ribosomes, which put together proteins.
¶There is a nucleus in almost all eukaryotic organisms (exceptions include mammalian red blood cells). Other frequently observed organelles include vacuoles, endoplasmic reticula, lysosomes, plastids (found in autotrophs), mitochondria, and the Golgi apparatus. Synaptic vesicles can also be found in specialized cells, such as neurons. The membrane encloses each of these structures. Despite not having a membrane surrounding them, macromolecular complexes such as ribosomes, spliceosomes, centrioles, and centrosomes are significant organelles in most cells because they carry out essential tasks like cytoskeleton organization, protein synthesis, and RNA processing.
