BIO.3 b - Cell Structure & Function

The student will investigate and understand relationships between cell structure and function.
Key concepts include
b) characteristics of prokaryotic and eukaryotic cells.

Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • All organisms are made up of tiny building blocks called cells.
  • The cell, the basic unit of all life, contains smaller organelles that assist in life processes that are similar in function to the larger organism.
  • The scientific theory of cells, also called cell theory, is a fundamental organizing principle of life on Earth.

  • I can grow plants in the correct location and arrangement to produce the best fruit.

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.

ESSENTIALS

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

b) compare and contrast characteristics of prokaryotic and eukaryotic cells.

     identify the following essential cell structures and their functions

     - the nucleus (contains DNA; site where RNA is made)

     - ribosome (site of protein synthesis)

     - mitochondrion (site of cell respiration)

     - chloroplast (site of photosynthesis)

     - endoplasmic reticulum (transports materials through the cell)

     - Golgi (site where cell products are packaged for export)

     - lysosome (contains digestive enzymes)

     - cell membrane (controls what enters and leaves the cell)

     - cell wall (provides support)

     - vacuole (storage of material)

     - cytoplasm (contains organelles and site of many chemical reactions)

     - centriole (organizes spindle fibers in animal cells)

     - cytoskeleton
