Decay

Complete the past question on decay

True or False?

1. Xylem carries minerals around the plant.2. The spongy layer of the leaf contains the

most chloroplasts.3. Magnesium is needed to make chlorophyll.4. Biological control uses chemicals.5. Phloem is where translocation of sugars

happens.
