Q4. The existence of two types of leaves in the same plant, is called
Solution
Heterophylly is the phenomenon in which morphologically dissimilar leaves are produced on the same plant body. Many aquatic plants, e.g., Ranunculusscleretus produce very much dissected submerged leaves with simple and entire floating leaves at the same time on the same plant body.

Q6. In which of the following types of fruits, dorsiventral dehiscence takes place?
I. Legume
II. Follicle
III. Siliqua
IV. Capsule
Solution
Legume or pod fruits and siliqua fruits can be dehisced through dorsal and ventral sutures. Legume is developed from a monocarpellary, one chambered and superior ovary, eg. pea, while siliqua develops from a bicarpellary, syncarpous and superior ovary, e.g., mustard.
