Answer 1

Answer:

A stem performs following below functions:

(i) In order to get maximum sunlight, stem and its branches hold the leaves.

(ii) Stem transfers water from roots to various parts of the plant.

(iii) It transports food from leaves to various parts.

(iv) It bears leaves, flowers and fruits.

Answer 2

Answer:

Hibiscus - reticulate venation, tap root system

Tulsi - reticulate venation, tap root system

Banana - parallel venation, fibrous root system

Grass - parallel venation, fibrous root system

Explanation:

Reticulate venation:

• Vein networks with reticulate venation have asymmetric vein configurations.
• Veins are typically seen in dicots and are arranged in the shape of a network.

It can be divided into the two categories below:

One midvein is present, and the other veins create a mesh-like structure in a condition known as pinnate reticulate venation or unicostate reticulate venation.

Example: Hibiscus, Coriander, Tulsi

Parallel venation:

• Veins that are parallel to one another are said to have parallel venation.
• Veins are typically seen in monocots and are aligned parallel to one another.
• The presence of midveins categorizes parallel venation into pinnate parallel venation and unicostate parallel venation, where veins develop perpendicular to the midvein towards the margin and are parallel to each other.
• These veins emerge from the evident midvein found in the center of the leaf lamina from the base to the apex. Banana leaves serve as an illustration.
• Numerous noticeable veins that run parallel to one another are referred to as palmate parallel venation or multicostate parallel venation.
• Both convergent parallel venation and divergent parallel venation are possible variations of it.

Example: banana, grass, maize

Tap root:

• Small, lateral roots known as root hairs are linked to the main central root of a taproot.
• Examples of taproot systems include mustard, carrot, beetroot, parsley, china rose, and all dicotyledons.

Fibrous root:

• Contrarily, fibrous roots are bushy roots that develop thin, somewhat branched roots from the stem.
• The fibrous root system is present in many plants, including all monocotyledons, rice, wheat, maize, marigolds, and bananas.
