Your accelerated biology learners will add to their understanding of cell structure with this resource. Taking them beyond the basics of mitochondria and chromatin, it also queries them about actin microfilaments and the extracellular...

In this cells worksheet, students compare the characteristics of eukaryotic and prokaryotic cells. Students describe how different scientists contributed to the cell theory. This worksheet has 6 short answer questions and 1 graphic...

In this human cells learning exercise, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

Who were the key players in cell theory? Use a handout to help young biologists record the basics about cell theorists and cell types. It refers to chapter seven of a textbook, but does not include the name of the textbook. 

For this cells worksheet, students review how the cell theory was developed. Students review the structure and function of cell structures and active transport. This worksheet has 30 fill in the blank questions.

The first of three pages in this handout provides a brief history of our understanding of the cell. It also differentiates between prokaryotic and eukaryotic cells. The second is a collection of true and false, multiple choice, and short...

In this history of life worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 11 clues given. Then students review how paleontologists use fossils to learn more about past living things...

Essay on the history of our knowledge of cells and the development of the cell theory.
