//True or False

The plants prepare food using sunlight. {T}

Carbohydrates act as food for plants only. {F}

The presence of chlorophyll is a characteristic feature of green plants. {T}

The green color of plants is attributed to the presence of chlorophyll. {T}

Plants do not need oxygen to carry out respiration. {F}

Photosynthesis occurs only in the leaves of the plants. {F}

Photosynthesis can occur in plants even without sunlight. {F}
