Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

An animal cell is not visible to the naked eye and is about 10 to 30 micrometers. A micrometer is one one-thousandth of a millimeter. They are so small that it takes a microscope with a magnification of at least 400x to be able to see inside the cell. These cells are what make up the basic units of structure and function in all living things. They carry out our life processes and make it possible for us to function and live. Inside these cells are organelles‚ which are smaller than the cell itself

CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

Animal Farm by George Orwell is parallel to the Russian revolution. It shows how evil people achieve and maintain power and explains the way the masses are controlled.

Cell division in animals: mitosis‚ cytokinesis‚ and the cell cycle. Cell division in animals is a two-step process involving mitosis and cytokinesis and is set up by interphase. Interphase is a growth period for the cell. In the nucleus the chromosomes are duplicated but are not yet distinguishable because they are still a form of chromatin. There is also a nucleoli‚ one or more‚ present producing ribosomes that are sent to the cytoplasm. Mitosis is the division of the nucleus and multiplication
