Cells: Cell Organelles

 

Cell organelles (Greek: “organon” = tool) have specific functions that are crucial for the cell’s survival. To understand the complex interactions of organelles within a cell and to develop an idea of how different metabolic processes are connected with each other, it is necessary to identify these functions for each organelle in a cell.

 

Overview over Functions of Different Cell Organelles

The worksheet "Functions of Cell Organelles" focusses on attributing the correct tasks to each cell organelle. To download the document, just click the button on the right.

For those experiencing difficulties with the task, additional hints are available in the document "Functions of Cell Organelles - Help".


As always, the solutions for this worksheet are available in our Online Shop.

Chloroplasts

The first step in learning how chloroplasts work is to get to know how they are built. The worksheet "Structure of Chloroplasts" focusses on this aspect. To download, just click the button on the left.


Solutions for this worksheet are available in our Online Shop.

Mitochondria

When working on developing an understanding of the functionality of mitochondria, it is helpful to study their structure first.

The worksheet "Structure of Mitochondria" poses the task to name the constituents of mitochondria. To download the worksheet, simply click the button on the right.


Solutions for this worksheet are available in our Online Shop.

 and Function in Mitochondria - incl Solution)

 

Endosymbiotic Theory

 

The animated PowerPoint Show “Endosymbiotic Theory” investigates the origin of complex cell organelles like chloroplasts and mitochondria. It explains and illustrates how feeding relationships between early eukaryotes and free-living prokaryotes may have evolved into endosymbiosis and how this may have given rise to our modern, complex eukaryotic cells.


It is available for purchase in our Online Shop.

Comparison of Chloroplasts and Mitochondria

In order to consolidate our knowledge about chloroplasts and mitochondria, comparing them is quite a useful task. Click the button on the right to download the worksheet "Comparison of Chloroplasts and Mitochondria". 

The solution is available in the Online Shop.

The animated PowerPoint-Show "Transport of Substances through Membranes" explains how substances can cross biological membranes. Furthermore, it supports understanding these different mechanisms of transportation with animated sketches. So, you can read about it AND you can watch it happen.

The PowerPoint-Show "Transport of Substances through Membranes" is available in our Online Shop.

(Cells - Transport of Substances through Membranes)

Matching this PowerPoint-Show, we also offer the accompanying worksheet "Transport of Substances through Membranes - Worksheet" (solutions included) which is also available in the shop. It not only aims at summarizing the information provided in the PowerPoint-Show but also applies it to exercises and experimental data for evaluation.

 and Osmosis - Solution)

 
 

Diffusion and osmosis are not just theoretical concepts that can be shown in sketches or simulated in models only. It is also possible to observe them in living tissue. 

The objective of the virtual lab "Plasmolysis and Deplasmolysis" is to observe the effect of changing outside conditions on the living cells of Elodea canadensis, an aquatic plant.

The interactive PowerPoint-Show “Virtual Lab: Plasmolysis and Deplasmolysis” offers microscopic photographs of cells of Elodea canadensis during plasmolysis and deplasmolysis.


This lab is available for purchase in our Online Shop.
