Final answer:
The statement about organelles functioning like organs within a cell is true. Key examples of organelles include mitochondria and chloroplasts, which are essential for energy production and photosynthesis, respectively.
Step-by-step explanation:
The statement that organelles act like organs inside a cell is indeed true. Organelles are specialized structures within cells that perform various functions necessary for the cell's life. For example, the mitochondria, often referred to as the powerhouses of the cell, generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. Another example is chloroplasts, which are found in green plants and are responsible for photosynthesis, allowing the plant to convert sunlight into glucose, a source of energy.
Within the eukaryotic cells' complexity, there are various other organelles, such as the nucleus, containing the cell's genetic material (DNA), and vacuoles, which store materials and waste products. All these organelles work together, much like organs in a body, to keep the cell functioning properly.
