History of microorganisms’ discovery Anton van Leeuwenhoek was the one of the first people to observe microorganisms‚ and used a microscope of his own design‚ and made one of the most important contributions to biology. [18] Robert Hooke was the first to use a microscope to observe living things; his 1665 book Micrographia contained descriptions of plant cells. Before Leeuwenhoek’s discovery of microorganisms in 1675‚ it had been a mystery why grapes could be turned into wine‚ milk into cheese

difference between a prokaryote and a eukaryote? Give an example of each. A prokaryote has no nucleus‚ while a eukaryote does. An example of a prokaryote is bacteria. An example of a single celled eukaryote is a paramecium. An example of a multi-celled eukaryote is an animal cell. 16. Give three examples of single celled eukaryotes. Three examples of single celled eukaryotes are paramecium‚ amoeba‚ and euglena. 17. What features help a single celled eukaryote function? One of the biggest things

Choose 2 pieces of evidence (that we learned about in class) and explain how they support the theory that eukaryotes evolved from prokaryotes. Eukaryotes and Prokaryotes differ in many ways‚ although‚ there are three major differences. One of these differences is that Prokaryotes do not contain a nucleus; Eukaryotes contain a nucleus. The second major differences is that Prokaryotic cells are

Plants‚ also called green plants‚ are multicellular eukaryotes of the kingdom Plantae. They form a clade that includes the flowering plants‚ conifers and other gymnosperms‚ ferns‚ clubmosses‚ hornworts‚ liverworts‚ mosses and the green algae. In biology‚ kingdom (Latin: regnum‚ pl. regna) is the second highest taxonomic rank below domain. Kingdoms are divided into smaller groups called phyla. Traditionally‚ textbooks from the United States used a system of six kingdoms. A fungus (/ˈfʌŋɡəs/; plural:

Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound organelles. Their genetic material consists of one or more linear strands of
