سؤال 16

In a class debate about where plants get their food, one student argues that a plant takes food in from the soil through its roots. Which correction states what actually happens?

The plant makes its own food by photosynthesis in its green partsپاسخ درست
The plant takes in ready-made food through its leaves instead
The plant absorbs food from the soil, but only through its stem
The plant takes in food from the soil only while it is dark

توضیح

A plant builds its own sugar from simple raw materials using light energy, and that is exactly what photosynthesis does and what makes a plant a producer, so nothing edible is absorbed ready-made. Roots do take substances from the soil, but those substances are moisture and dissolved minerals, and swapping a root for a leaf leaves the same wrong idea in place.
