Leaf Venation Grade 4

What is the term used to describe leaf venation pattern where veins form a network or mesh-like structure?

• Reticulate

• Palmate

• Pinnate

• Parallel

In which type of leaf venation do the veins run parallel to each other from the base to the tip of the leaf?

• Palmate venation

• Dichotomous venation

• Pinnate venation

• Reticulate venation

What is the main function of leaf venation in plants?

• Distribution of water, nutrients, and sugars

• Enhancing photosynthesis

• Regulation of temperature

• Protection against predators

Name one advantage of reticulata leaf venation in plants.

• Strong framework for supporting the leaf structure

• Weaker leaf structure prone to damage

• Less efficient nutrient transport

• Increased water loss due to higher surface area

How does parallel leaf venation differ from reticulata leaf venation?

• Parallel leaf venation has a simple pattern of veins, while reticulate leaf venation has a network of veins.

• Parallel leaf venation has veins running parallel to each other, while reticulate leaf venation has a network of veins forming a complex pattern.

• Parallel leaf venation has veins forming a network, while reticulate leaf venation has parallel veins.

• Parallel leaf venation has a complex pattern of veins, while reticulate leaf venation has veins running parallel.

What is the significance of leaf venation in the process of photosynthesis?

• Leaf venation determines the color of the leaf during photosynthesis

• Leaf venation is significant in photosynthesis as it facilitates the transport of water, nutrients, and sugars within the leaf.

• Leaf venation helps in attracting sunlight for photosynthesis

• Leaf venation is responsible for producing oxygen in photosynthesis

Explain how leaf venation helps in maintaining the structure and shape of a leaf.

• Leaf venation helps in maintaining the structure and shape of a leaf by changing color

• Leaf venation helps in maintaining the structure and shape of a leaf by attracting insects

• Leaf venation helps in maintaining the structure and shape of a leaf by providing support, distributing essential substances, and preventing wilting.

• Leaf venation helps in maintaining the structure and shape of a leaf by producing oxygen

How does reticulate leaf venation differ from parallel leaf venation in terms of nutrient transport?

• Reticulate leaf venation is more efficient in nutrient transport compared to parallel leaf venation

• Parallel leaf venation is more efficient in nutrient transport compared to reticulate leaf venation

• Both reticulate and parallel leaf venation have similar efficiency in nutrient transport

• Neither reticulate nor parallel leaf venation is involved in nutrient transport
