What structures do plant and animal cells have in common? Ribosome -Lysosomes -mitochondria -cell membrane -nucleus
The correct answer and explanation is:
The correct answer is ribosomes, mitochondria, cell membrane, and nucleus.
Both plant and animal cells share several common structures that are essential for the basic functions of the cell. Here’s an explanation of each:
- Ribosomes: These are small organelles responsible for protein synthesis. Ribosomes can either be free in the cytoplasm or attached to the endoplasmic reticulum (ER). In both plant and animal cells, ribosomes play a crucial role in translating messenger RNA (mRNA) into proteins, which are essential for cellular functions.
- Mitochondria: Known as the powerhouse of the cell, mitochondria are the sites of cellular respiration. They generate ATP (adenosine triphosphate), which cells use as an energy source. Both plant and animal cells contain mitochondria because they both require energy for metabolism, growth, and other functions.
- Cell Membrane: The cell membrane surrounds the cell and regulates the passage of substances in and out of the cell. This semi-permeable membrane is made of a lipid bilayer with embedded proteins. It is crucial for maintaining the cell’s integrity, signaling, and communication with other cells. Both plant and animal cells have cell membranes.
- Nucleus: The nucleus is the control center of the cell, housing the cell’s DNA, which contains the instructions for protein synthesis and cellular functions. It is surrounded by a nuclear membrane and contains structures like nucleoli, which are involved in ribosome production. Both plant and animal cells have a nucleus, and it plays a central role in regulating cell activity and division.
While both plant and animal cells share these structures, they also have differences, such as the presence of chloroplasts in plant cells and the different types of vacuoles in plant and animal cells. However, the structures mentioned above are essential for the functioning of both types of cells.
