Lesson Leaves

CH 23 Lesson 1 (STEMS & LEAVES)

4.7 Stems 

• 4.7.1 Explain how the structure of the stem facilitates its three functions including

  leaves, branches, and flowers production; holding leaves up to the sun; and

  transporting substances throughout the plant

• 4.7.2 Contrast the processes of primary growth and secondary growth in stems;

  including the type of plant, the result of the growth and the role of the cambium

  tissue and a

  
  

• 4.7.3 Describe the formation of wood, tree rings and bark 

Open Ended

Search and Identify one Type pf STEM, and give example for it.

Multiple Choice

• leaves, branches, and flowers production

• photosynthesis

• hold leaves up to the sun

• transporting substances throughout the plant

4.8 Leaves

• 4.8.1 Describe how the structure of a leaf enables it to carry out photosynthesis

  4.8.2 Relate between the structure and the function of the leaf parts in transpiration and photosynthesis; including: epidermis, vascular tissue, palisade mesophyll, spongy mesophyll, Stomata

  4.8.3 Explain how gas exchange in leaves relates to homeostasis Including the role of stomata

  4.8.4 Explain the process of water movement in a plant

  4.8.5 Describe how the products of photosynthesis are transported throughout a plant

• 4.8.6 Examine stomata structure
