Which structure is common to plant and animal cells? a. chloroplast b. central vacuole c. mitochondrion d. centriole

Verified step by step guidance

1. Identify the structures listed and understand their functions: Chloroplasts are involved in photosynthesis and are typically found in plant cells. Central vacuoles, which store nutrients and waste products, are also primarily found in plant cells.
2. Recognize that mitochondria are the powerhouses of the cell, providing energy through cellular respiration and are found in both plant and animal cells.
3. Understand that centrioles are involved in cell division and are found in animal cells but not in typical plant cells.
4. Compare the options given with the knowledge of cell structure presence in both plant and animal cells.
5. Conclude that the correct answer is 'c. mitochondrion' because it is the only structure listed that is common to both plant and animal cells.

Key Concepts

Cell Structure

Both plant and animal cells are eukaryotic, meaning they have a defined nucleus and membrane-bound organelles. Key structures include the cell membrane, cytoplasm, and various organelles that perform specific functions, such as energy production and waste management.

Mitochondrion

Mitochondria are known as the powerhouses of the cell, as they generate adenosine triphosphate (ATP) through cellular respiration. This organelle is present in both plant and animal cells, playing a crucial role in energy metabolism.

Chloroplasts and Vacuoles

Chloroplasts are specific to plant cells and are responsible for photosynthesis, while central vacuoles are large storage organelles found primarily in plant cells. In contrast, animal cells may have smaller vacuoles but lack chloroplasts, highlighting the differences in cell function and structure.
