Question

how do the various modifications help plants??

Answer 1

the normal functions of leaf are photosynthesis respiration and transpiration decide these functions the leaves have to perform some other functions ;
hence they modify themselves into the

different ways as following

1) tendrils:* in some plants the entire leaf or part of it get modified into called thread like structure called tendril
*tendril helps the plant climb up
eg: pea , glossaries,clematis

2)spines: *in many plants the leaves are there apices and modified into thin sharp and pointed structures known as spines
* they help in defence
eg: opuntia,aloe ,ziziphus

3)scale leaves :* in onion and garlic mostly all the news are present in the form of fleshy scales
* they stores the food
eg: allium cepa

4)leaf picture:* it is the modification of leaf in insectivorous plant in Lid to trap the insects there are number of digestive glands in the inner walls of the picture these glands secrete of fluid with digest insects
eg: nepenthes ( picture plant)

5) phyllode: *the petiole becomes green flatenned and leaf like and it is called as phyllode
eg: Australian acacia

Answer 2

Hello!!

_________________________________

$\Huge{\mathfrak{\purple{\underline{ANSWER}}}}$

➡️ The main function of the leaves is to carry out the process of photosynthesis. However, in a few plants, leaves are modified to perform different functions.

⭕Tendrils:

The leaves of a pea plant are modified into tendrils that help the plant in climbing.

⭕ Spines:

The leaves in cactus are modified into sharp spines that act as an organ of defense.

⭕ Phyllode:

The leaves of some Australian acacia are short-lived and soon replaced by flattened, green structures called phyllodes that arise from the petiole of the leaves. The petioles in these plants synthesize food.

⭕ Pitcher:

The leaves of the pitcher plant are modified into pitcher-like structures, which contain digestive juices and help in trapping and digesting insects.
