Leaves - Results Tables

The two experiments outlined here explore different aspects of plant physiology. The first experiment seeks to determine which surface of a leaf is responsible for water loss. A results table is set up to record the water level in millilitres across five days. The experiment compares water loss when no leaf surface is exposed, when both surfaces are exposed, and when either the upper or lower surface is exposed individually. This systematic approach allows for a clear observation of water loss patterns, which could provide insights into the transpiration process of leaves and how they interact with their environment.

The second experiment investigates whether there is a correlation between the length of a holly leaf and the number of spikes it has. A results table is prepared to note down the length of each leaf in millimetres and the corresponding number of spikes. This experiment is conducted over five different leaves, allowing for a range of data to be collected. The aim is to analyse any potential relationship between the physical size of the leaf and its spike count, which could reveal adaptive traits or growth patterns specific to holly plants.
