Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

For this cells worksheet, students review the 14 organelles found in plant cells. Students identify their shape by coloring them in on a plant cell diagram.

Give this summary of 16 pages of a text to your class to deepen understanding of cell permeability, diffusion, ions, and more. The handout portion includes vocabulary clarifications, detailed color diagrams, and important information;...

Students investigate the concept of diffusion and how materials enter and leave a cell. In this movement across a membrane lesson plan, students use perfume, food coloring in water and a sugar cube in water to observe diffusion. They...

In this diffusion through a membrane worksheet, high schoolers fill in the blanks to complete 27 statements about cell membranes, the movement of molecules across the cell membrane, concentration gradients and diffusion.

In this cell organelles activity, students read the structure and function of different plant and animal cell organelles to determine what organelle is being described. Students write in the 15 organelles into a chart.

In this life cycle worksheet, 9th graders complete 3 different procedures that distinguish viruses and bacteria and inherited characteristics. First, they read the background excerpt given about bacteria and viruses. Then, students cut...

Students create three-dimensional cell models. They may choose to make either a plant or animal cell but must use a Ziploc bag as the cell membrane, slime for the cytoplasm, and strawberry baskets for the cell wall if making a plant...

Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Learners observe the cells of an onion by wet mounting it and viewing it in a microscope.  For this hands on lesson students make their own wet mount slide of an onion and are able to identify the cells in it such as, the nucleus,...

In this biology instructional activity, students locate and identify each of the vocabulary terms relating to cells on the bottom of the sheet. There are 27 biology terms to locate in the word search.

This module focuses on cell structure and how the organelles function together to form the smallest unit of life. The cell theory is also discussed along with the basics features of the cell. Site also includes an interactive practice...

This site lets students practice vocabulary words related to cell organelles. The same vocabulary words are presented in one of four different games for students.

Describes the three types of plant cells and their differences, and the structures within a plant cell and their functions.

Brief text summary of what students learn in the Diffusion across a Selectively Permeable Membrane lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Main teaching points include...

Explains the process of facilitated diffusion which allows selective movement of materials across the cellular membrane.

Endocytosis enables cells to absorb extracellular nutrients that are needed for their survival. In receptor-mediated endocytosis, a protein receptor on the cell membrane binds to a nutrient molecule and facilitates its absorption through...
