Ask your teacher for help. We little compartments. Cork is a substance have prepared a temporary mount of which comes from the bark of a tree. This onion peel. We can observe this slide was in the year 1665 when Hooke made this under low power followed by high chance observation through a self-designed powers of a compound microscope. microscope. Robert Hooke called these boxes cells. Cell is a Latin word for 'a little room'. This may seem to be a very small and insignificant incident but it is very important in the history of science. This was the very first time that someone had observed that living things appear to consist of separate units. The use of the word 'cell' to describe these units is being used till this day in biology. Let us find out about cells. 5.1 What are Living Organisms Made Up of? Activity 5.1 Fig. 5.1: Compound microscope Let us take a small plece from an onion bulb. With the help of a pair of forceps. What do we observe as we look through we can peel off the skin (called the lens? Can we draw the structures that epidermis) from the concave side (inner we are able to see through the microscope, layer) of the onion. This layer can be on an observation sheet? Does it look like put immediately in a watch-glass . Fig. 5.2? containing water. This will prevent the peel from getting folded or getting dry. What do we do with this peel? Let us take a glass slide, put a drop of water on it and transfer a small piece of the peel from the watch glass to the slide. Make sure that the peel is perfectly flat on the slide. A thin camel hair paintbrush might be necessary to help transfer the peel. Now we put a drop of safranin solution on this plece followed by a cover slip. Take care to Fig. 5.2: Cells of an onion peel
