INTERDEPENDENCE BETWEEN THE SPECIES INTERACTION BETWEEN PLANTS AND ANIMALS: Animals are depending upon plants for their food shelter and also for various things. ANIMALS HELP PLANTS IN DIFFERENT WAYS 1.Many animals are involved in the pollination in plants. 2.Fruits and seeds of many plants are dispersed by animals 3.Decomposers convert organic substances into inorganic substances so that plants can absorb them easily.

The Observation of organism in a drop of pond water (Paramecium) under LPO and HPO Compound Microscope Doreenda A. Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually

reproduction may have short term benefits when rapid population growth is important or in stable environments‚ sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity‚ allowing adaptation to changing environments. Paramecium is a group of unicellular ciliate protozoa‚ which are commonly studied as a representative of the ciliate group‚ and range from about 50 to 350 μm in length. Simple cilia cover the body‚ which allow the cell to move with a synchronous motion (like

In the Kingdom Exploration lab‚ five different organisms were observed under a microscope‚ (Yeast‚ Paramecium‚ Elodea‚ Daphnia‚ Euglena). Each of these organisms is apart of one of the six kingdoms‚ (Eubacteria‚ Archaebacteria‚ Fungi‚ Protista‚ Plantae‚ and Animalia) which are apart of three domains‚ (Archaea‚ Bacteria‚ and Eukarya). In this lab‚ however‚ none of the organisms observed were archaea or bacteria. Also‚ all the organisms were eukaryotes‚ not prokaryotes‚ which are organisms without

They move with the help of microscopic hair-like structures called cilia‚ which act like oars to push them through the water. They swim by rotating slowly and changing directions often There is be Two Methods For Locomotion. That They use The
