SBI3U1-04 Final Exam Study Notes Unit 1: Diversity of Living Things 1.1 Importance of Biodiversity Spotlight on Honeybees Very important‚ pollinate flowers allowing plants to reproduce Play vital role in food chain‚ if they die‚ all organisms that rely on them will die as well Dying because of pesticides‚ parasitic Varroa mite (infects beehives and sucks of bees’ blood)‚ the Israeli acute paralysis virus (immobilizes and kill bees) No genetic diversity = Less resistant to parasites

Evolution - Changing of things over time to benefit the organism in natural selection. Biological evolution happened at the level population ‚ not the individual organism level. Lack of need‚ Climate change‚ population change Adaptations is at population level not individual level they are a result of natural selection Devolvment of diversity Because a genetics re combinations mutations and othe mechanisms that lead to variation there is what Darwin called descent with modification

More complex organisms can communicate through alternative means.[1]A diverse array of living organisms can be found in the biosphere of Earth‚ and the properties common to these organisms—plants‚ animals‚ fungi‚ protists‚ archaea‚ and bacteria—are a carbon- and water-based cellular form with complex organization and heritable genetic information. The Earth was formed about 4.54 billion years ago. The earliest life on Earth existed at least 3.5 billion years ago

Question: Describe five different organelles and their functions. Explain the similarity and differences between eukaryotic cells and prokaryotic. All eukaryotic cells‚ whether from animals‚ plants‚ protists‚ and fungi‚ are fundamentally similar to one another but different from prokaryotic cell. A eukaryotic cell contains various other organelles‚ which perform specific functions in the cell. These organelles can be organized into few basic functional groups such as genetic control‚ distribution

There is a wide range of eukaryotic organisms‚ including all animals‚ plants‚ fungi‚ and protists‚ as well as most algae. Eukaryotes may be either single-celled or multicellular. In eukaryotes‚ genetic material‚ or DNA‚ is contained within an organelle called the nucleus‚ where it is organized in long molecules called chromosomes. The plasma

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein
