Animal and Fungi Biology: Key Concepts and Characteristics
Key Concepts in Animal Biology
Body Temperature Regulation
What kind of animal does not use its energy to regulate its body temperature?
Ectotherm
How does the minimum body size compare in ectotherms and endotherms?
Ectotherms have a smaller minimum body size.
What kind of animal uses its energy to regulate its body temperature?
Endotherm
Which will lose body heat to its environment at a faster rate if all other conditions are the same?
A small animal will lose body heat at a faster rate.
Body Size and Environment
How do animals in a water setting compare in size to animals in a land setting?
Animals in a water setting are larger because the buoyancy of water supports them.
Embryonic Development
What is the function of Hox genes in an animal?
They set up the directions of the body axis.
A pseudocoelomate animal has:
A body cavity with endoderm inside and mesoderm outside.
An acoelomate animal has:
No body cavity.
A coelomate animal has:
A body cavity with mesoderm to the inside and outside.
A protostome has:
Spiral cleavage.
A deuterostome has:
Radial cleavage.
An animal embryo has the archenteron make a complete tube, and the first opening becomes the anus. This animal is a:
Deuterostome
An animal embryo has the archenteron make a complete tube through the embryo, and the first opening becomes the mouth. This animal is a:
Protostome
An animal embryo is at the 8-cell stage. One cell separates from an embryo, leaving one group with 7 attached cells plus one separate cell. This produces twins. This animal is a:
Deuterostome
An embryo at the 8-cell stage has four cells at the top directly above four cells below. This animal is a:
Deuterostome
An embryo at the 8-cell stage has four cells at the top rotated and offset from the four cells below. This is called:
Spiral cleavage
An embryo at the 8-cell stage has four cells at the top rotated and offset from the four cells below. This animal is a:
Protostome
An animal embryo is at the 8-cell stage. One cell separates, which produces two partial embryos that are missing body parts. This animal is a:
Protostome
An animal embryo at the 8-cell stage has four cells at the top directly above four cells below. This pattern of development is called:
Radial cleavage
Key Concepts in Fungi and Plant Biology
Fungi Characteristics
Which group of fungi is a current serious cause of death in frogs?
Chytrids
What is the difference between a coenocytic hypha and a septate hypha?
A coenocytic hypha has multiple nuclei in a single cell membrane.
In fungi reproduction, what does the term karyogamy mean?
Fusion of nuclei
In fungi reproduction, is karyogamy part of sexual reproduction or asexual reproduction?
Sexual reproduction
Which best describes lichens?
A mutualism interaction between a fungus and an algae.
Plant Characteristics
A monocot has:
All of these characteristics describe a monocot.
A eudicot has:
All of these characteristics.
Which of the following scientific names is written correctly?
Triceratops prorsus (both italicized)
Which of the following cells transport sugars over long distances?
Sieve-tube elements
Which of the following cells or tissues arise from lateral meristem activity?
Secondary xylem
Which of the following characteristics could determine whether a developing organism is a protostome or deuterostome?
The embryo exhibits spiral cleavage or radial cleavage.
