C) Root growth causes auxin concentrations to decrease
B. LEAF ADAPTATION
The main function of the leaf is in the processes of photosynthesis and
transpiration. Apart from these functions, leaf is sometimes adapted to
perform other functions.
Examples of leaf adaptations are for:
a)
Support, which could be seen by the presence of tendrils
b)
Catching insects, by having cup-liked shape of hairs sensitive to
touch
c)
Reproduction, by having meristematic cells able to produce new
shoots that will go on to become new individual plants
d)
Food and water storage, especially found in plants living in dry areas
where water is scarce (for example succulent plants, having leaf storing
food and water)
e)
Floatation, for plants living on the water surface, their leaves in
general will have air openings on tissues (used for floating) usually
found on leaf petiole
f)
Protection, by having leaves completely or partially modified as thorns
Instruction:
a)
1. Search for ONE plant species with the following leaf adaptations
2. Give their scientific names…
(i)
"One bad apple spoils the bunch". Explain this idiom in a scientific way and
phytohormone behind this reaction.
The same phytohormone is a necessary devil. Explain the positive contributions in
terms of plant defense and fruit industries.
(ii)
