In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

This learning object will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

In this video, learners view the parts of an animal cell and its organelles.

Learners play a game of Tic-Tac-Toe to test their knowledge of normal red blood cells, platelets, and abnormal red blood cell morphology.

In this animated object, learners are introduced to the structure and function of animal cell organelles.

Learners examine the different stages of maturation for red blood cells, white blood cells, and platelets. A quiz completes the activity.

In this interactive object, learners identify the parts of an animal cell and its organelles.

In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.

In this animated activity, learners examine nanotechnology applications that are based on cell membrane structure and function.

Students read how to lock a cell that is being referenced in a formula so that it does not automatically show an increment when the formula is copied.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.

In this animated object, learners examine the different phases of a cell's life.

Learners read how fruits are classified according to their texture and according to how they developed from their floral anatomy.

Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.

In this well-illustrated object, learners examine basic floral anatomy. The flower is the reproductive organ of the angiosperm.

This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.

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.
