Observation of the apparent distinguish taxonomic characters from fresh and preserved specimen and recognition of plants and animals on the basis of their taxonomic characters.
Examination under the microscope an animal cell (frog’s blood cells) and a plant cell (epidermal cells of onion) using an appropriate temporary staining technique, such as iodine or methylene blue.
Identify from fresh preparations, (1) the cell membrane, nucleus and cytoplasm in an animal cell and (2) the cell wall, cell membrane, sap vacuole, cytoplasm, nucleus and chloroplast in a plant cell.
Preparation of the wet/ mount tissue from the flowering plants or study of plant and animal tissues from charts / prepared slides.
