The cells of all plants have:
chloroplasts but not mitochondria, and use carbohydrates to power their functions. chloroplasts but not mitochondria, and use proteins to power their functions. mitochondria but not chloroplasts, and use proteins to power their functions. chloroplasts and mitochondria, and use carbohydrates to power their functions.
The correct statement is: chloroplasts and mitochondria, and use carbohydrates to power their functions.
In plants, chloroplasts are responsible for photosynthesis, where they convert light energy into chemical energy stored in carbohydrates. Mitochondria are involved in cellular respiration, where carbohydrates are broken down to produce ATP, the energy currency of the cell. Therefore, plant cells contain both chloroplasts and mitochondria.
