Types of Venation in Plants: Parts and functions – Class 6 Science Experiment

Chapter Name: Plants: Parts and functions

Activity Name: Types of Venation in Plants: Parts and functions

Activity Description:

Required Items:

1. Leaves collected in Activity 1
2. Figure showing different types of venation

Step by Step Procedure:

1. Collect the leaves that were previously collected in Activity 1.
2. Observe the venation patterns on the leaves carefully.
3. Compare the observed venation patterns with the venation patterns shown in the figure.
4. Record your observations in the table provided.

Experiment Observations:

Record your observations in the table below. Fill in the information for each plant in the respective columns.

Table:

S.No	Plant	Venation (Reticulate/Parallel)
1	Rose	Reticulate
2	Mango	Reticulate
3	Bamboo	Parallel
4	Oak	Reticulate
5	Grass	Parallel

Precautions:

• Handle the leaves with care to avoid damaging their venation patterns.
• Ensure proper lighting and magnification (if required) to observe the venation clearly.

Lesson Learnt from Experiment:

By comparing the results obtained, we can draw the following conclusions:

1. Plants with parallel venation in their leaves usually have fibrous root systems.
2. Plants with web-like or reticulate venation in their leaves generally have tap root systems.
3. There is a correlation between the type of venation and the root system of a plant.
