mammals. 3) Slide 3: Why is the nucleus of the cell in slide 3 so large? In other words‚ what is this cell doing that requires that its nucleus be so large? (Please be specific). In eukaryotic cell in slide #3 has organelles including a nucleus containing DNA and mitochondria energy organelles .Compared to the prokaryotic cell which has the DNA in the cytoplasm smaller and simpler and doesn’t contain a nucleus or other organelles‚ it does have cell membrane. Bacteria and Archea are single celled

How microscopes have contributed to our understanding of living organisms There are 2 types of microscopes these are; light microscope and electron microscope. Light microscopes use a beam of light however the resolution is lower than the electron microscope so the image is not clear‚ however they can view living organisms. These types of microscopes are used in schools to view simple cellular structures‚ which is good to teach simple biology Mitosis and meiosis can be seen with light microscopes

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ 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

Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the

electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities between light microscopes and electron

Period: H Plants and Animal Cells Abstract: In this lab‚ you will find out how plant and animal cells are alike and how they are different. The onion elodea cells were both plants‚ so they had a cell wall. The cheek cells were animal cells‚ so they did not have a cell wall. Eukaryotic cells contain structures called organelles that carry out life processes. Eukaryotic cells can be classified by the types of organelles they contain. In plant and animal cells‚ similarities and differences exist because of varied life functions
