Activity Name: Types of Venation in Plants: Parts and functions
In this experiment, we will observe the venation patterns of leaves collected in a previous activity and compare them with the venation patterns shown in a figure. We will record our observations in a table.
- Leaves collected in Activity 1
- Figure showing different types of venation
Step by Step Procedure:
- Collect the leaves that were previously collected in Activity 1.
- Observe the venation patterns on the leaves carefully.
- Compare the observed venation patterns with the venation patterns shown in the figure.
- Record your observations in the table provided.
Record your observations in the table below. Fill in the information for each plant in the respective columns.
- 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:
- Plants with parallel venation in their leaves usually have fibrous root systems.
- Plants with web-like or reticulate venation in their leaves generally have tap root systems.
- There is a correlation between the type of venation and the root system of a plant.
