Unit
1:
Cells, Tissues, Organs, and Systems
The Cells, Tissues, Organs, and Systems
unit covers concepts related to three topics:
Cells
Students learn about the basic structure and function of plant
and animal cells. They use a microscope to observe cell structures,
and they use models to discover how cells interact with their
environment.
Animal Systems
Students investigate ways in which unicellular organisms meet
their basic needs. They also learn about the hierarchical organization
of animal cells into tissues, organs, and organ systems. They
learn about the structure, function, and interdependence of some
of the major human organ systems.
Plant Systems
Students learn about the hierarchical organization of plant cells.
They investigate certain specialized cells and tissues in different
parts of plants.
