Presentation Transcript
slide2

A Narcissus Bulb. Red Arrow = Mother Bulb, Blue Arrow = Succulent foliage leaves originating from the basal plate, Green Arrow = Basal plate (Stem), Yellow Arrow = Daughter Bulb.

slide3

A corm e.g. Gladiolus A corm is a modified stem. The stem is condensed and there are no succulent foliage leaves which are present on bulbs. The yellow arrow is pointing to new shoots developing from buds on the corm.

slide6
Offsets in Sempervivum.These are small stolons and succulent leaves for water storage with fine hairs to reduce transpiration.
slide7

A rhizome in a grass.The rhizome (as shown by the red arrow) is a creeping stem below ground. Buds are present on the rhizome which gives rise to new plants and allows the plant to spread asexually.

slide9

Insect-trapping leaves in insectivorous Pinguicula spp. The insects, which stick to the leaves, supply nitrogen as the plant grows in waterlogged, nitrogen poor soils.

slide10
A modified insect-trapping leaf in Droseraspp., an insectivorous plant. Insects are trapped by the sticky leaf hairs.
a modified leaf of nepenthes spp which forms a pitcher into which the insects fall and are trapped
