how do bulbs differ from other kinds of plants?

Answer 1

Well, one thing that is different about a bulb plant is that they store next years energy in the bulb and that is why you don't cut the foliage off until it has died completely to the ground.
Rooted plants get their energy directly from the sun and they don't have to store it in order to reemerge the following summer. Another thing is that the majority of bulbs flower in the spring where as plants with roots and rhizomes flower throughout the growing season. Also, Bulbs produce offspring that can be separated from the mother bulb and transplanted elsewhere which isn't that uncommon since you can see that with rhizomes and some rooted plants too. Those are the main differences I can think of.

Answer 2

They are basically storage units and also have the flower preformed inside of them before they are planted. This is not true of any other plant, although we are talking about true bulbs here, not corms or rhizomes. They have a basal plate from which roots develop, and which hold the preformed leaves together.

Answer 3

spiderlily, golden lily, blood lily, onions, tulips are some example of bulbs,. these underground parts has a funtion of storing foods and for propagating themselves,

for example the blood lily bloms only once a year, they remain dormant for sometimes and when the rain comes they shoot out of the ground showing its globious multi-umbels flower,

while other plants usually gets it nutrients directly from soil, and process it with the help of sun
