Whole leaf mount

Use the following videos and information to help you with the whole mount slide

Chloroplasts moving around in the cytoplasm in cells of an Elodea leaf

Elodea also known as pond weed is a freshwater, aquatic plant commonly used in aquariums and fish ponds. The leaves are very thin (1-2 cells thick), this means that when prepared as a whole mount microscope slide the light can move through the leaf allowing you to see individual cells and some of the organelles inside them. If left in a dark place prior to creating a slide it is possible to see the chloroplasts moving with the flow of the cytoplasm around the large central vacuole carrying out photosynthesis - this is known as cytoplasmic streaming, and it allows more efficient photosynthesis, by increasing the amount of light that is absorbed.

Key Structures to Identify and Write about in this Slide

Step 1 - Draw

After creating the whole mount slide, draw and label the structures seen in your slide

(follow all biological drawing rules, include a detailed title, magnification and stain information)

How could the drawing about be improved?

*** Show Mrs J your completed drawing and notes ***

Step 2 - written requirements

Select two of the key organelles that are visible in your slide and labelled in your drawing, make notes about the following for each organelle

Shape and structure of the organelle
Location of the organelle
The function of the organelle
How this organelle (function, shape, structure or location) enables the cell to carry out their specific function
