You will be expected to identify the following structures in the leaf of a dicotyledonous plant:

  • Chloroplasts
  • Cuticle
  • Guard cells
  • Stomata
  • Upper and lower epidermis
  • Palisade mesophyll
  • Spongy mesophyll
  • Air spaces
  • Vascular bundles (xylem and phloem)

FAQs on Identifying Leaf Structures in a Dicotyledonous Plant - Biology for GCSE/IGCSE - Year 11

1. What is the main function of the leaf structures in a dicotyledonous plant?
Ans. The main function of the leaf structures in a dicotyledonous plant is to carry out photosynthesis, where they absorb sunlight, carbon dioxide, and water to produce glucose and oxygen.
2. How are the leaf structures of a dicotyledonous plant adapted for photosynthesis?
Ans. The leaf structures of a dicotyledonous plant are adapted for photosynthesis with features such as a large surface area, thin and flat shape, and the presence of chloroplasts containing chlorophyll for capturing sunlight.
3. What are the key components of a leaf structure in a dicotyledonous plant?
Ans. The key components of a leaf structure in a dicotyledonous plant include the epidermis, mesophyll tissue (palisade and spongy layers), stomata, and veins (xylem and phloem) for transport of water, nutrients, and gases.
4. How does the cross-section of a leaf of a dicotyledonous plant help in its functioning?
Ans. The cross-section of a leaf of a dicotyledonous plant provides a visual representation of its internal structures, showing the arrangement of cells, tissues, and vascular bundles that are essential for photosynthesis, gas exchange, and nutrient transport.
5. How do the leaf structures of a dicotyledonous plant contribute to overall plant nutrition?
Ans. The leaf structures of a dicotyledonous plant play a crucial role in plant nutrition by synthesizing glucose through photosynthesis, which serves as a source of energy for the plant and supports growth, development, and reproduction.
