BIO.4 a-c - Archaea, Bacteria, & Eukarya

The student will investigate and understand life functions of Archaea, Bacteria, and Eukarya. Key concepts include
a) comparison of their metabolic activities;
b) maintenance of homeostatis; and
c) how the structures and functions vary among and within the Eukarya kingdoms of protists, fungi, plants, and animals, including humans.

Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • The structure and function of organisms are complementary.
  • Although living things vary greatly, they have many basic similarities.
  • Living organisms acquire the energy they need for life processes through various metabolic pathways (photosynthesis and cellular respiration).Homeostasis is an organism's ability to remain stable and stay alive by making changes to maintain equilibrium.
  • Homeostasis is an organism's ability to remain stable and stay alive by making changes to maintain equilibrium.

  • I can compare and contrast all living things.
  • I can explain why and how cells maintain homeostasis.
  • I can compare and contrast how various organisms, including humans, stay alive.

UNDERSTANDING THE STANDARD

  • The organisms that live on Earth today share many structural and metabolic features, including cellular organization, common molecular mechanisms for energy transformation, utilization and maintenance of homeostasis, common genetic code, and mechanisms for the transmission of traits from one generation to the next.
  • The diversity that is evident in the natural world can be studied in the local environment in the context of variations on a common theme.
  • Understanding normal body functioning assists in understanding situations when functioning is impaired.
  • Like other organisms, human beings are composed of groups of cells (tissues, organs, and organ systems) that are specialized to provide the human organism with the basic requirements for life: obtaining food and deriving energy from it, maintaining homeostasis, coordinating body functions, and reproducing.

ESSENTIALS

In order to meet this standard, it is expected that students will

a) compare and contrast the metabolic activities of all domains of life.

b) identify the proper response an organism would exhibit in response to changes in the environment to maintain homeostasis.

c) categorize and compare the Eukarya kingdoms based on cell structure, locomotion, reproduction, response to the environment and metabolism.
