Which of the following plants is not capable of manufacturing own food?
Explanation
Plants and other autotrophs manufacture their own food through photosynthesis, a process using sunlight, water, and carbon dioxide to produce glucose [c1][c3]. Algae are green, autotrophic organisms containing chlorophyll that can manufacture their own food [c2]. Similarly, carrots and cabbage are green plants (or parts of them) that utilize photosynthesis to store energy as carbohydrates [c4][c5]. In contrast, mushrooms are fungi, which are classified as heterotrophs [t3][t5]. Fungi lack chlorophyll and cannot perform photosynthesis; instead, they obtain energy by breaking down or absorbing organic matter from other organisms or dead material [t2][t3]. Therefore, while algae, carrots, and cabbage are capable of producing their own food, mushrooms must rely on external organic sources for nutrition [t6][t8].
