BIOL227 Algae Exam Questions and
Answers 100% Pass
What is Phycology? - ✔✔The study of Algae
What are the Five Kingdoms? - ✔✔Animals; Plants; Fungi; Protisa; Monera
What is meant by Kingdom? - ✔✔Animals are grouped based on if they share a
common ancestor and share characteristics (maybe from an ancestor).
Groups should be monophyletic-A group with a common ancestor and all its
descendants.
What is a Protista? - ✔✔Protists are a very large, diverse group of organisms, including
the plant-like protists (algae), fungi-like protists, and the animal-like protists
(protozoans). They are all eukaryotic, and most are unicellular. Traditional taxonomy of
protists (Kingdom Protista) did not accurately represent evolutionary relationships, so
the classification of this group is unsettled. Modern taxonomy has rearranged the group
formerly known as Kingdom Protista, separating the different types of organisms into
their own candidate Kingdoms.

,Protists vary in how they obtain energy (autotrophic or heterotrophic) and in their
locomotion.
What are Protista divided by? - ✔✔They are divided by locomotion mode. And none
are phototsynthetic
What are locomotion methods used by Protista? - ✔✔Flagellated; Ciliated; Amoeboid
movements (Pseudopodia)
What are the 3 domains of life? Which are prokayotic and eukaryotic? - ✔✔Bacteria-
prokaryotic; Archaea-prokayotic; Eukaryota (fungi. (plants animals etc..)
What are Archaea? - ✔✔Single celled organisms like bacteria which exist in extreme
environments (extremophiles)
What does EuBacteria "true bacteria" do? - ✔✔*Live everywhere
*Eat everything
*Get energy in many different ways
*Also do oxygenic photosynthesis (cyanobacteria -"Blue-green algae: Cyanophyta)
What are the important structural features of Oxygenic photosynthesis? -
✔✔*Membrane proteins- polarity
*Transmembrane gradient of protons

,What is photosynthesis? - ✔✔Process of turning Electromagnetic radiation to chemical
energy
Uses:
*Photosystem I & II, Reaction center chlorophyll
*ALL oxygen-producing organisms have chlorophyll a
What are characters are Algae grouped by? - ✔✔1. Pigments
2. Storage products (what and where)- 3. 3. Carbohydrate
4. Flagellation
5. Cell wall Composition
6. Cell Structure
7. Habitat
8. Life Cycles
What are Cyanobacteria? - ✔✔Cyanobacteria is a group of bacteria, which make their
own food by the process of photosynthesis. They are called as such because they are
generally pigmented. Some cyanobacteria examples include blue-green bacteria and
cyanophyta.

, What is the environmental importance of cyanobacteria? - ✔✔Cyanobacteria,
previously called blue-green algae, are one of the oldest known life forms. It is thought
that these organisms were among the first land colonizers of the Earth's early land
masses, and played an integral role in the formation and stabilization of early soils. The
earliest cyanobacteria fossils found are called stromatolites, which date back more than
3.5 billion years. Extremely thick mats of these organisms converted the earth's original
carbon dioxide rich atmosphere into one rich in oxygen and capable of sustaining life.
Can be found in all environments
What are Stromatolites? - ✔✔*Rock formations that could not be formed by non-biotic
process.
*Present day stomatolites contain cyanobacteria
What is the problem with cyanobacteria? - ✔✔*Some cyanobacteria produce toxins
-But not always or in all conditions
-Detrimental effect occur when cyanos in large numbers -blooms
Is Cyanobacteria prokaryotic or eukarytoic? - ✔✔*Cyanobacteria is prokaryotic
*Membrane system (photosynthetic membranes)
What pigments does Cyanobactera use for photosynthesis? - ✔✔*Chlorophyll a - all
*Chlorophyll b - specific group
