DNA synthesis, RNA synthesis and cell reproduction
The three major parts of a cell are the cell membrane, which encloses the cell and controls what enters and exits; the cytoplasm, which contains organelles and where cellular processes occur; and the nucleus, which houses the cell's genetic material.
Transcription occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. It is the process of copying a segment of DNA into RNA by RNA polymerase. This RNA molecule can then be used to produce proteins or perform other cellular functions.
Most of a cell's life processes occur in the cytoplasm, where metabolic reactions take place. The nucleus controls cellular activities by directing protein synthesis. Mitochondria are where cellular respiration occurs, generating energy for the cell.
Outside the nucleus is the cytoplasm, the jelly-like substance where organelles are located. It also contains various proteins, nutrients, and other molecules necessary for cellular function. The cytoplasm acts as a medium for different cellular processes to occur.

nuclei
This cell has a nucleus, membrane-bound organelles, and linear DNA, which are features found in eukaryotic cells but not in prokaryotic cells. This nucleus houses the cell's genetic material and separates it from the rest of the cell's activities, allowing for more complex cellular functions to occur.
If the nucleus divided but the cytoplasm did not, it would result in cells with multiple nuclei. This condition is known as multinucleation and can occur naturally in certain cell types or as a result of cellular stress. Multinucleated cells may have altered functions and can be associated with developmental abnormalities or disease.
If osmosis does not occur in a cell, the cell may not be able to regulate the exchange of water and solutes with its environment effectively. This could lead to cellular dehydration or swelling, disrupting various cellular functions and potentially causing the cell to burst or collapse.
Multi-nucleate refers to a cell or organism that contains more than one nucleus. This can occur naturally in certain cells, such as muscle cells, where multiple nuclei help facilitate cellular functions. Abnormal levels of multi-nucleation can also be seen in certain diseases or conditions.
Technically there are three parts to cellular respiration; glycolysis, the citric acid cycle, and the electron transport chain. Of the three, glycolysis occurs within the cytosol and the other two components occur within the mitochondria.
The anaerobic reactions of cellular respiration occur in the cytoplasm of the cell.
