Observing Protists through Hay Infusion Preparation Abstract: Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now‚ there are many known species of protists. After learning about protists in class‚ the group decided to observe the different species of protists found in pond water. The group prepared a preparation to be able to culture the protists until it was time to view them. After a few days‚ the

Synopsis – Grade 9 Science Term II Chapter 1: Atoms and Molecules Law of conservation of mass: Mass can neither be created nor can it be destroyed in a chemical reaction. Law of constant proportion: A chemical substance always contains the same elements in a fixed proportion by mass‚ irrespective of the source of compound. Atom: The smallest particle which is the building block of matter. The symbol of the element is made from one or two letters of the English

Introduction To differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could

A study on the life cycle of soil-borne Dictyostelids. Dictyostelid cellular slime moulds (or Dictyostelids) are unicellular‚ bacterivores thriving abundantly in the soil surface that exhibits an alternating life cycle between growth and multicellular development in response to the environmental changes. This study was conducted to isolate and culture Dictyostelids from the soil to observe this unique life cycle. Soil sample was collected and diluted to volume. A measure of 0.6 mL of the soil

of life b) What is a unicellular organism? An organism that consists of only one cell c) Can a cell be multicellular? No because a cell is the smallest unit of life‚ cells can however join together to start forming something else 2. a) What is a difference between prokaryotic and eukaryotic cells? b) What is one significant similarity? Prokaryotic cells do not have a neucleus and Eukaryotic cells do have a nucleus. One similarity is that both are covered by a cell membrane and contain RNA as
