Collection of specimen
We have defined biology as the study of living things. For effective study, a biologist may have to collect some living things or some parts of living things for observation and analysis.The living things or parts of living things that are used for biological study are called specimens.
Biological studies always take place in laboratories.A laboratory is a building or a room that is designed and equipped for scientific studies.
Collections of living things especially animals may not be very easy.Some of the animals are not easy to catch while some are quite dangerous. Knowledge on proper specimen collection and handling of is very important.
We will discuss some of the apparatus used in specimen collection.
1. Sweep net:This is used for catching flying insects.
