Document Summary
Mosses are bryophytes, non-vascular plants with no true roots or leaves. The leaflets are small enough that we may observe them readily by making a wet mount of the whole leaflet and observing with a light microscope. In this investigation, you will observe two different species of moss: 1: make a prediction about which species would have more chloroplasts. Prepare wet mounts of one leaflet from each moss. Count the number of chloroplasts per cell for at least ten cells of each moss species. 4: draw a labelled diagram of a grouping of 2-3 cells of each moss species. Perform a t-test on your data to determine whether the average number of chloroplasts per cell is significantly different between the species of moss you observed: discuss in your conclusion/evaluation. Records appropriate quantitative and associated qualitative raw data, including units and uncertainties where relevant. Records appropriate quantitative and associated qualitative raw data, but with some mistakes or omissions.
