BOTANY
Continuing our study of; ‘it’s all about those
plants, those plants, those plants’ , we have
moved inward from the edge (or margin) of a
leaf (refer to our previous ‘WUp’) to: kinds of
leaves, kinds of roots and shapes of corolla.
Petals (corolla) are modified leaves that surround the reproductive parts of
flowers. They are often brightly coloured and attractively shaped to draw in
pollinators, such as butterflies and bees. Together, the petals of a flower are
collectively referred to as a corolla. This week we learnt about the different
shapes of corolla. The pictures depict - ‘see it, draw it, then find it’!
Tubular, one shape of corolla, is (no surprise!) tube-shaped as found in the in
‘Coral Honeysuckles’, labiate is lip-like as seen in ‘Orchids’, cruciform is cross-
shaped as in ‘Periwinkles’ and personate is shaped like a bell as seen in
‘Allamandas’.
We also spoke about the fibrous roots and the tap roots.
