Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans ..

.10 - Prokaryotic and Eukaryotic Cells The eukaryotic cells have an organised nucleus. The genetic material is found forming a distinct thread like chromatin. It is bound by a distinct nuclear membrane that separates it from the surrounding cytoplasm. Membrane bound cell..

(animals which have saprotrophic nutrition) are Mastigamoeba and Chilomonas. The digestive juices are secreted by the cell membranes which means the general body surface as they are single-celled protozoans. Saprotrophs are different from detritus feeders which do not..

One of the main characteristics used in defining grades of animal complexity is the presence or absence of tissues. Tissues are the aggregations of embryologically and morphologically similar cells that become arranged to perform specific functions. The protozoans occur as singl..

Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells. In unicellular organisms like the protozoans, the gamete-producing individuals are called gametocytes. The gametes may be similar - isogam..

Introduction - Materials formed in one part of the body have to be taken up to other parts where they are needed or to be got rid of. This is an essential requirement of most animals. This function is performed by the body fluids. The movement of the body fluids i.e. blood and lymph from one part o..

Cilia and flagella are fine vibratile cytoplasmic processes arising from basal bodies. They are similar in their structure, chemical composition and function. Both serve to propel the organism or move a medium past a fixed cell. However, they differ in their size, number and mode of beat..

Question: What is fission? Give two examples of organisms that reproduce by fission. Answer: The DNA or the nucleus of a mature cell divides first and then the cell divides into two. This is called fission. It produces daughter cells of almost the same size...
