Which one of the following plants exhibits an example of anisophylly, where the different size of leaves are present in opposite phyllotaxy?
1 Ranunculus aquatilis
2 Gold fussia
3 Limnophila heterophyllum
4 Vallisneria spirilis
Explanation:
B Ranunculus aquatilis is aquatic plant, growing in mats on the surface of water . - Goldfussia is an example of anisophylly, where the different size of leaves are present in opposite phyllotaxy generally the opposite leaves of a plant are of the same size. - Limnophila heterophyllum is marsh weed light green leaves contrast.

Whorled, simple leaves with reticulate venation are present in :
1 Alstonia
2 Calotropis
3 Neem
4 China Rose
Explanation:
A Whorled simple leaves with reticulate venation are present in Alstonia. - In leaves of Alstonia are simple elliptical or ovate linear to lanceolate and wedge-shaped at the base these are leathery and sessile. The leaf blade is dorsiventral and arranged in a whorl with the entire margin. - The leaf venation is pinnate, with numerous veins ending in a marginal vein.

Identify the wrong statement:
1 Stipules in Lathyrus are persistent.
2 Phyllotaxy in Trillium is alternate.
3 Venation in Caulophyllum is parallel.
4 Caulline leaves are found in Cocos.
Explanation:
B Phyllotaxy-In Trillium is alternate is wrong answer because- In alternate phyllotaxy, consecutive leaves are produced in a spiral manner around the stem. This is seen in rose plant. (a) Stipules in Lathyrus are persistent- The stipules remain attached to the leaf for the entire life of the leaf. In Lathyrus, the stipules are present in the form of large leaf. (c) Venation is the arrangement of veins on the leaves. It is either parallel or reticulate. In Calophyllum, the venation is parallel. (d) Leaves arising from the main stem are called cauline leaves. Example include rose, cocos, maize.
