1: Algae and Fungi
1. Differentiate between members of green, red, and brown algae.
2. Learn the characterisitics of the Phyllum Fungi observed in lab.
3. Review the organisms which comprise lichens.
4. Use paper chromatography to separate photosynthetic pigments
of green plants and algae.
Student Learning Objectives (SLO)
1. Differentiate between the red, brown, and green
compare them using Table 1.
2. Be able to identify the Phylla of Fungi presented in this lab.
3. Observe the microscopic structure of the different fungi
4. Understand the composition of lichens and their ecological role.
5. Learn the basics of paper chromatography.
6. Use chromatography to understand the origin of land plants
1. Review this laboratory and procedures.
2. For background read Chapters 28 and 31 in Campbell (7
3. Bring 2-3 fresh leaves from a plant whose pigments you wish to
examine by paper chromatography.
4. Bring your copy of
A Photographic Atlas for the Biology
, 5th Edition to the lab.
5. Bring your personal protective gear (lab coat, safety goggles,
The term “algae” (singular, alga) refers to relatively simple,
eukaryotic, aquatic photo-autotrophs. Your text divides the algae into
seven groups: the
(red algae). Following the classification
scheme of your text (Campbell, 7
edition), all of these groups
except Rhodophyta hold the taxonomic status of phylum. Some
taxonomists advocate including the Chlorophyta (green algae) in the
Plant kingdom. (See Campbell, Figure 28.8, p. 554).
Because of time and availability you will only examine specimens
from the green, brown, and red algae in this laboratory.
base these groups on several characteristics (refer to Table 1-1)
including photosynthetic pigments, carbohydrate food reserves,
