INTRODUCTION Most familiar plants Are green, contain chlorophyll, and manufacture their food through the process of photosynthesis. Are immobile and rooted to the ground. Have neither nervous system nor excretory system. Have a cell wall composed largely of cellulose. Can continue to grow almost indefinitely by cell division.

Discovery of ANTIBIOTIC - PENICILLIN Let’s make this as an example, I believe everyone knows about antibiotics – medicine used to treat bacterial and fungal infections but not viral diseases Alexander Fleming discovered the organism that can suppress the growth of bacteria when he SAW an unusual petri dish/ glassware in his experiment on bacterial isolates from sore throat or boils. Alexander Fleming This instructional material must not be copied, reproduced, distributed, published, displayed, modified, or in any way exploited any such content. (Sir ABC) This lecture materials are provided for educational purpose specifically BIOL 1100 General Botany. Story continues… Returning from holiday on September 3, 1928, Fleming began to sort through petri dishes containing colonies of Staphylococcus, bacteria that cause boils, sore throats and abscesses. He OBSERVED something unusual on one dish. It was dotted with colonies, save for one area where a blob of mold was growing. The zone immediately around the mold— later identified as a rare strain of Penicillium notatum—was clear, as if the mold had secreted something that inhibited bacterial growth. This instructional material must not be copied, reproduced, distributed, published, displayed, modified, or in any way exploited any such content. (Sir ABC) This lecture materials are provided for educational purpose specifically BIOL 1100 General Botany. He discovered a “MOLD” or fungi inside the petri dish and observed that the bacteria did not grow or touch the area with mold This is where he hypothesized that the mold can stop the growth of bacteria This instructional material must not be copied, reproduced, distributed, published, displayed, modified, or in any way exploited any such content. (Sir ABC) This lecture materials are provided for educational purpose specifically BIOL 1100 General Botany. What is our undertaking in this story? Fleming used the scientific method to explain what really happened on what he observe from his experiment Of course, he rerun many trials and replicates to make sure that this discovery is accurate, precise and valid. From his conclusion, we are now enjoying the benefits of his discovery of antibiotics to treat human and animal bacterial infections This instructional material must not be copied, reproduced, distributed, published, displayed, modified, or in any way exploited any such content.

Scientific Method is a realistic method for acquiring knowledge which improved the development of science. The practice of scientific method is well known in the field of Biology which explores the potential answers to the different phenomena of life. It is crucial to develop critical thinking skills, sound judgement and keen analysis in the field of life science to further improve the skills of the students for advanced learning and research experimentation.
