Xylem primarily functions to transport water and dissolved minerals from the roots of the plant to the rest of the plant, including the leaves and stems. It plays a crucial role in supporting the plant and maintaining its water and nutrient supply.
The other options you mentioned are associated with different parts of the plant:
- Transport food is primarily the function of phloem, which moves sugars produced during photosynthesis from the leaves to other parts of the plant.
- Prevent water loss relates more to structures like stomata and the cuticle on leaves, which help in regulating water loss.
- Perform photosynthesis is carried out by chloroplasts in the leaves, where light energy is converted into chemical energy.
So, the correct answer regarding the function of xylem is that it transport water.
