Penn Foster - Biology Lesson 5, Plant
and Animal Systems, and Behavior,
EXAM (700042RR) 100% Pass
1. How would a biologist classify the plant stem shown? - ✔✔Dicot stem
2. In ferns, the plant structure that produces sperm and egg cells is known
as which of the following? - ✔✔Gametophyte
3. Fish respiratory systems exchange gas and receive oxygen at the gills.
This oxygen then enters the bloodstream and is pumped through the heart
and back through the gills without first returning to the heart.
This order of events best describes which type of circulation system? -
✔✔Single loop
4. Animals must digest food once it's consumed.
The diagram shows the steps involved in which type of digestion? -
✔✔Intracellular digestion
5. Root vegetables, such as carrots, are classified as what type of root
system? - ✔✔Taproot system
, 6. A new organism has been discovered. This organism has a bilaterally
symmetric unsegmented body. It's capable of moving on its own with a
muscular appendage and is encased in a large shell that seems to be
attached to its body.
Based on this evidence, which phylum would this new animal likely be
classified into? - ✔✔Mollusca
7. The evolution of lungs and gill, which developed to serve a similar gas-
exchange purpose in distantly related organisms, is an example of what
type of evolution? - ✔✔Convergent evolution
8. Which of the following accurately describes the correct order of events in
the process of transpiration within a plant? - ✔✔Water enters the roots,
gets transported through the stem, and evaporates through the leaves.
9. Which of the following describes a phenomenon that occurs when we
observe plants that wilt? - ✔✔The stomata close, cutting off transpiration
and gas exchange.
10. Plants that we recognize today spend the majority of their life in the... -
✔✔diploid phase.
11. Which process does the plant need energy to perform? - ✔✔Pulling
nutrients into the root hairs
