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

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.
