Question:

Which of the following statements is false about a leaf? 1. A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the margin 2. A leaf is said to be compound when the incisions of lamina reach up to the midrib breaking into several leaflets 3. Leaf is the most important vegetative organ for photosynthesis 4. Leaf is not a transpiratory organ

Options:

1. A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the margin
2. A leaf is said to be compound when the incisions of lamina reach up to the midrib breaking into several leaflets
3. Leaf is the most important vegetative organ for photosynthesis
4. Leaf is not a transpiratory organ

Solution:

Stomata present in leaves help in transpiration i.e. loss of water through leaves. Page 69-70, XI NCERT
