Biology 11 Kingdom Plantae Review #1
Evolution of Plants
____1. Name one main chemical that all cells need a constant supply of.
____2. Describe why plants need rigid support in their stems if they are to be successful
at living on land.
____3. List at least two important materials that are transported throughout a terrestrial
plant through a vascular (transport) system.
____4. What is a cuticle, and why is it a necessity for living on land?
____5. Describe the design that land plants have for ensuring that their reproduced
zygotes do not dry out before establishing their own network of roots.
____6. List 4 key evolutionary developments that plants have acquired to make
them more successful at living in drier terrestrial environments.
Characteristics of Algae
___ 1. According to our classification system that we use; what Kingdom do
multicellular algae belong to?
___ 2. Other than living in or near water, list the other key structural differences
between algae and most true (higher) land (terrestrial) plants?
___ 3. Describe why it is that algae must live in or near water?
____4. Explain why it is that taxonomists place some algae in Kingdom Protista and
other algae in Kingdom Plantae.
___ 5. Explain why algae do not require rigid stem-like structures, like the terrestrial
plants possess.
____6 What is the proper term for the parts of a multicellular alga that holds it to
rocks.
___ 7. Algal leaves and other algal structures lack a protective waterproof covering
called a cuticle, explain why this structure (cuticle) is not only unnecessary for
survival, but also explain why the possession of such a protective layer would
hinder their survival.
____8. As much light is reflected off of the water's surface, the amount of light being
absorbed by water is reduced. Which two wavelengths (colours) of light are most
readily absorbed by seawater and as a result do NOT penetrate to the lowest
depths?
____9. Which type of pigment do all types of algae possess?
____10. Not all pigments are of the green type (chlorophyll), what are these types of
pigments called and what do they allow certain algae to do?
Classification of Algae
___ 1. What are the two main characteristics used for classifying algae?
____2. Give the phyla names for both the brown algae and the red algae.
___ 3. Give the phylum name for the green algae.
____4. Describe two characteristics common to all members of this phylum.
____5. A characteristic common to members of chlorophyta as well as to all plants is the
possession of a cell wall, what is this cell wall made out of?
____6. For each description name one member with that morphological characteristic:
a) A unicellular green alga
b) A colonial green alga
c) A filamentous green alga
d) A multicellular green alga
___ 7. Make a sketch of Volvox.
___ 8. Make a sketch of Spirogyra
____9. Chlamydomonas is very similar to a plant-like protist we studied last unit. Name
the plant-like protist it resembles and list at least two structural similarities.
____10. What is the more proper name for sea lettuce?
____11. Most common seaweeds belong to which phylum?
____12. For the brown algae Fucus, describe the role of each structure:
a) Stipes/blades
b) Bladder
c) Holdfast
____13. Members from which phylum can grow at the most extreme depths?
____14. Write out the proper definition for "Alternation of Generations" – use the
glossary
Ecological Role of Algae
___1. Give the approximate percentage of oxygen on Earth is due to algae.
___ 2. Name five food items that contain products from algae.
___3. Describe the problems associated with an algal bloom.
