Exploring Leaf Venation and Roots

What is leaf venation?

• Leaf venation is the arrangement of veins in a leaf.

• The color of a leaf's surface.

• The size of a leaf's petiole.

• The type of plant species a leaf belongs to.

Name the two main types of leaf venation.

• Circular and Spiral

• Random and Clustered

• Parallel and Reticulate

• Horizontal and Vertical

What is parallel venation?

• Parallel venation is a leaf venation pattern where veins run parallel to each other.

• Veins form a net-like pattern in leaves.

• Veins are absent in leaves with parallel venation.

• Veins are randomly arranged in a leaf.

Give an example of a plant with parallel venation.

• Maple tree (Acer spp.)

• Rose bush (Rosa spp.)

• Oak tree (Quercus spp.)

• Banana plant (Musa spp.)

What is reticulate venation?

• A random arrangement of veins without any specific pattern.

• A pattern of straight parallel veins in leaves.

• Reticulate venation is a net-like pattern of leaf veins.

• A circular arrangement of veins around the leaf stem.

Name a plant that exhibits reticulate venation.

• Hibiscus

• Maple

• Pine

• Cactus

What is a tap root?

• A tap root is a type of leaf structure.

• A tap root is the main root that grows vertically downward and is thicker than lateral roots.

• A tap root is a root that only grows in waterlogged soil.

• A tap root is a shallow root system that spreads horizontally.

What is a fibrous root?

• A fibrous root is a root system that consists of a few large roots.

• A fibrous root is a root system made up of many thin, branching roots.

• A fibrous root is a single, thick root that grows deep into the soil.

• A fibrous root is a type of root that stores nutrients and water.

What type of root system does grass have?

• Taproot system

• Adventitious root system

• Storage root system

• Fibrous root system

What is the primary function of roots?

• To facilitate photosynthesis in leaves

• To store energy for the plant

• To produce flowers and fruits

• The primary function of roots is to anchor the plant and absorb water and nutrients.
