sativum) is a dicotyledonous plant which belongs to family Fabaceae
2

Maize is a cross pollinating plant while pea is a self pollinating plant.
Fruits may be classified as
➢ dry OR succulent/fleshy
➢ dehiscent (pericarp bursts to liberate seeds) OR indehiscent (no bursting, seeds liberated by decay of pericarp),
➢ true (develop from ovary wall) OR false (develop from floral structures other than, or as well as, the ovary wall),
➢ simple (form from a single flower), aggregate (from several ovaries in a single flower) OR multiple (from the flowers of
an inflorescence).
Classify the following fruits according to the features listed above.
Malus domestica
