Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

After studying the structure and functions of living cells using textbooks, internet or encyclopedias, students prepare a PowerPoint presentation on cell structure and present it to the class.

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

Using stunning computer imagery, this resource introduces life science learners to cells. It zeros in on the animal cell and the function of its more prominent organelles. Additional support is offered in the form of a self-assessment...

Liken a cell and its organelles to a tiny person and its organs. After gathering information on cell structures and their functions, small groups collaborate to come up with an analogy of their own. They produce a collage describing the...

As your class views each slide, they will be introduced to the organelles and structure of the cell.  Details about structure and function are given and also some trivia about their frequency and population. There is also some...

Each of these slides deals with an individual organelle and displays a diagram along with labels of the structures. The most useful components of this slideshow are the summaries of functions and descriptions of how the organelles are...

Students clarify common misconceptions about cells. They assess initial knowledge of cells and cell behavior, read and discuss an article and consider the role of cell communication in the diseases of diabetes, multiple sclerosis and...

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

Incorporate multiple facets of the cell into your next high school lab! Through an introduction to cell organelles, class members observe each cell type and draw visuals to further demonstrate understanding of cellular processes in both...

Wow! Separate organelles from the cells of dried peas. Observe vacuoles in beet cells. Watch protists in action. Examine SEM photographs. Beginning biologists get a complete exposure to the structure and function of cell organelles. Two...

Students define the function of the different parts of a cell. In this biology lesson, students  discuss cell structures and how its organelles perform basic functions. They differentiate between human and animal cells.

Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and  reinforces the higher-order...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

This PowerPoint deals with some of the basic cell tasks and how structures are specialized to help with those. The makeup of the cytoskeleton and centrioles is explained and some nice pictures of a cell cross-section will help recap for...

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

If the only support you are in search of is lists of vocabulary terms, this presentation may fit the bill. Slides simply list terminology. These categories are included: hierarchy of structural organization, cell functions, cell...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

Students examine the concept of osmosis in relation to dehydration. They identify the function and structure of semi-permable membranes. They predict how certain processes can affect the characteristics of an organism.
