Chapter 5 The pundamental UNTt of Life While examining a thin slice of cork, Robert Hooke saw that the cork resembled the structure of a honeycomb consisting of many avoid air bubbles while putting the little compartments. Cork is a substance which comes from the bark of a tree. This needle. Ask your teacher for help. We was in the year 1665 when Hooke made this heedle. Ask your teacher for help. We chance observation through a self-designed onion peel. We can observe this slide under low power followed by high microscope. Robert Hooke called these boxes cells. Cell is a Latin word for 'a little room'. powers of a compound microscope. 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 - Let us take a small plece from an onion What do we observe as we look through bulb. With the help of a pair of forceps, 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. 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 frollowed by a cover slip.
