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

➡️ 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.

Answer 2

Answer:

The leaf modifications are-

1. Tendrils

2. Phyllode

3.  Spines

4.  Pitcher

Explanation:

Leaves are an important part of the plant as they provide the site for the process of photosynthesis in plants.

Leaves in response to the environment modify themselves and become adapted which gets passed on to the generations and become permanent in a population like  

1. Tendrils: observed in Pea plants help the plant to climb and attach to the substrate.

2. Phyllode: observed in Acacia become adapted to synthesize food through photosynthesis.

3. Spines: observed in Opuntia act as a defensive mechanism to herbivores.

4. Pitcher: observed in Pitcher plant store digestive enzymes to digest the insects.
