Question 1. 
Paheli wonders what kind of stem - the money plant, beanstalk, gourd plants and grape vines have. Do observe some of these plants. How are these different from a herb, a shrub or a tree? Why do you think some of them need support to climb upwards? 
Answer:
The stems of the money plant, beanstalk, gourd plants and grape vines are different from herb, shrub or a tree because their stems are very weak and unable to support the weight of the plant.

As a result they grow horizontally over the ground surface Or climb up with the support of wall or other plant or object. Plants with weak stems that cannot stand upright and spread on the ground are called creepers, while those take support on neighbouring structures and climb up are called climbers.

Boojho has a brilliant idea! If he wants to know what kind of roots a plant has, he need not pull it out. He just has to look at its leaves!
Answer:
Yes. This is because the leaf venation and the type of roots in a plant are related in a very interesting way. Plants having parallel venation have fibrous roots, and those with reticulate venation have taproots.
