In this animated object, learners examine the different phases of a cell's life.
In this animated activity, learners examine nanotechnology applications that are based on cell membrane structure and function.
In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
Explore what passive transport diffusion is and how it moves water through a membrane.
In this animated object, learners examine water molecules moving through a semipermeable membrane.
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.
Learners read about the mutations that occurred in plants for the successful transition from an aquatic to a terrestrial existence. The classification of plants is based on these adaptive structures.
In this learning object, students will learn about the attachment
process of specific sugars to red cell membranes and how the sugars
determine ABO antigenic activity.
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.
