Memorial State University South La Union Campus College of Education Laboratory High School Agoo‚ La Union Research (Elective II) Chapter I INTRODUCTION Background of the Study Plants are living organisms that belongs to the kingdom of plantae. They include organism such as herbs‚ trees‚ bushes‚ grasses‚ vines‚ ferns‚ green algae. The study of plants‚ known as botany‚ has identified about 350‚000 species of plants. Green plants sometimes called viridiplantae‚ obtain most of their

genetics‚ that examines heritable changes in gene expression in organisms (active versus inactive genes) that doe not involve changes in the underlying DNA sequence. This means a change in phenotype occurs‚ which changes the observable characteristics of an organism‚ while the genotype of the organisms stays the same. Although‚ epigenetic changes are regular and naturally occurring‚ other factors can influence the phenotype of an organism. Some of these factors include age‚ environment‚ and disease
Premium DNA Gene Genetics
Genetic engineering is the scientific manipulation of genes in order to modify the offspring of an organism. It may work with plants‚ humans or other animals. However‚ the various forms of this technology have led many to argue that the manipulation of genes constitutes a threat to humans and disturb the delicate balance of biodiversity which exists in nature. The main concern of human genetic engineering is that it may possibly change the genetic characteristics of unborn babies. It is widely

Strong evidence suggests that different types of photosynthetic cyanobacteria underwent endosymbiosis that evolved into different

The process of modifying the genetic composition of a mammal scientist starts with Deoxyribonucleic acid (DNA). DNA makes up the genes of all living things and by using DNA sequencing scientist are able

CHAPTER 1 : A LOCAL ECOSYSTEM What is an ecosystem? Characteristics? The size of a population of organisms? Factors for this variation? Environmental factors? An ecosystem is any environment containing living organisms that interact with each other and with the non-living parts of the environment. Largely self-sustaining. - materials and energy are exchanged via food webs. - any size. (eg. a pond‚ a forest‚ a desert or a piece of bushland.) Does not

Cells are not smaller that 0.1 um because within the cell all the necessary components have to take place‚ cellular metabolism‚ reproduction‚ photosynthesis and there has to be a sufficient amount of space for that to

Contributors to Microbiology Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24‚ 1632- Aug. 30‚ 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work
