17 Questions
What are some key characteristics of animals?
How they acquire and assimilate food
True or false: Animal diversity is not important to understand animal form and function.
False
What are some exclusive innovations of the animal kingdom?
Collagen, muscle tissue, and nervous tissue
True or false: Animals do not differ from other eukaryotic kingdoms in terms of acquiring and assimilating food, molecular and tissue innovations, reproduction, and Hox genes.
False
True or false: Animal body plans are not built on shared characteristics and basic symmetries.
False
How do animals reproduce?
Through haploid sperm joining haploid egg to form a diploid zygote that undergoes cleavage and gastrulation
True or false: Cephalization and radial symmetry enabled animals to pursue a different kind of life.
False
What are Hox genes and what do they control?
They are genes found in all animal phyla except sponges that control gastrulation and organogenesis
True or false: All animal tissues originate from embryonic tissues developed by the blastopore.
False
What are the three types of symmetry that animals can have?
Radial, bilateral, and asymmetrical
What is cephalization and how did it enable animals to pursue a different kind of life?
It is the clustering of neurons and sense organs, which enabled animals to pursue a different kind of life
True or false: Flatworms are examples of coelomates.
False
What are the two types of animals based on their body cavities?
Coelomates and acoelomates
True or false: Deuterostomes differ from protostomes in that their blastopore becomes the mouth.
False
True or false: The Cretaceous mass extinction played no role in the rise of angiosperms and mammals.
False
What is an acoelomate and give an example?
An animal without a body cavity, such as a flatworm
What is the difference between protostomes and deuterostomes?
Protostomes have spiral cleavage and deuterostomes have radial cleavage
Study Notes
- Animal diversity is important to understand animal form and function.
- Key characteristics of animals include how they acquire and assimilate food, presence of exclusive molecules and tissues, mode of sexual reproduction, and Hox genes.
- Collagen, muscle tissue, and nervous tissue are exclusive innovations of the animal kingdom.
- Animals reproduce through haploid sperm joining haploid egg to form a diploid zygote that undergoes cleavage and gastrulation.
- Hox genes control gastrulation and organogenesis and are part of a gene family found in all animal phyla except sponges.
- Animals can have radial, bilateral, or no symmetry.
- Cephalization, or clustering of neurons and sense organs, enabled animals to pursue a different kind of life.
- Animals can develop from 2 or 3 embryonic germ layers and have or lack body cavities.1. Different animal phyla have different body plans and characteristics.
- The three types of worms - earthworms, nematodes, and flatworms - have different body structures.
- All animals have specialized cells and tissues that form organs and organ systems.
- Vertebrates have more complex organ systems than invertebrates.
- Animals can be either coelomates or acoelomates.
- Acoelomates, like flatworms, do not have a body cavity.
- Animals can be protostomes or deuterostomes.
- Protostomes have spiral cleavage and deuterostomes have radial cleavage.
- Mesoderm development and the fate of the blastopore during gastrulation differ between protostomes and deuterostomes.
- All animals converge to the gastrula during embryonic development.
