• Leaf spot disease

• Curly top disease

Which insect is responsible for spreading the curly top disease according to Dr. Esau's findings?

• Thrips

• Aphids

• Whiteflies

• Leaf hoppers

What is the primary function of dermal tissue in plants?

• Covering the external surface of the plant

• Supporting the plant structure

• Storing food

• Transporting nutrients

Which cells in the vascular tissue of plants are responsible for transporting water?

• Xylem cells

• Meristem cells

• Phloem cells

• Parenchyma cells

What is the role of phloem cells in plants?

• Protecting against pathogens

• Transporting water from roots to leaves

• Providing structural support

• Transporting sugars from leaves to other parts of the plant
