Draw the picture of sporophyll and write about it ?
Answers
A sporophyll is a leaf that bears sporangia. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls, or microsporangia and are called microsporophylls.
The sporangium-bearing leaves (sporophylls) occur in zones among the vegetative portions of the stems. In most, however, the sporophylls occur in specialized compressed stems called cones or strobili. Each sporophyll is associated with one yellow to orange kidney-shaped sporangium.
Plants that produce sporophylls include: Alaria esculenta a brown alga shows sporophylls attached near the base of the alga. Lycophytes, where sporophylls may be aggregated into strobili (Selaginella and some Lycopodium and related genera) or distributed singly among sterile leaves (Huperzia).
