the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain

Yeast|48| Neurospora|50| Reflection Questions: Summarize your amino acid comparison in paragraph form. To guide your summary‚ reflect on the following questions. What does it mean when scientists say that living organisms share a universal genetic code? It means that all extinct organisms have all the same genetic code. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? the near-universal genetic code is that all extant things share some type of common

THE LEGEND OF THE FIRST BANANA FRUIT Once‚ there was an extremely beautiful princess‚ became of which she was called Mariang Maganda (Maria‚ the beautiful one). Her house was near a small forest which grew many delightful flowering plants. Every day the young princess would go about picking flowers found there and place them nicely in a basket to bring home with her. As soon as she arrived home‚ she would sting the flowers together to form a long lay of flowing colors. Then she would put them

Observing Various Cells Under The Microscope Chapter 6 Lillian Hayner Biology 211 Lab section 14 New Mexico State University Elodea Wet Mount If cytoplasmic screening is occurring‚ you will see the chloroplast circulating around the cell. Cytoplasmic streaming is controlled by microfilaments in the cell’s cytoskeleton. These filaments of actin and myosin move cellular contents in an active process that uses energy released by breaking ATP down in ADP. How might a cell benefit by spending

the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the solution in a period of 10 minutes

CHAPTER 1 Cell Structure and Organisation Cells * All living organisms are made up of cells * The simplest living organisms have one cell only * His name is unicellular-e.g. bacteria. * Most other living organisms have many cells- his name is multicellular- e.g. Man‚ plants‚ animals. * Cells can be seen only under microscope Cell structure All cells have the following structure in common: a) Cell membrane- a very thin layer of protein and fat‚ surrounding the cell. It is

I. Rationale Banana is a staple starch for many tropical populations.Depending upon cultivar and ripeness‚ the flesh can vary in taste from starchy to sweet‚ and texture from firm to mushy. Bananas are an excellent source of vitamin B6 and contain moderate amounts of vitamin C‚ manganese and dietary fiber. There many uses of the “banana”; banana sap from the pseudostem‚ peelings or flesh may be sufficiently sticky for adhesive uses‚ the large leaves may be used as umbrellas and many more. One

Effect of temperature on banana ripening Individual Student Research Project 2012 Aim To investigate which temperatures slow or quicken the ripening process of bananas. Introduction and Background Information Thousands of dollars are spent to ripen bananas to the perfect point while transporting them so that they ripen‚ do not over ripen and remain edible when they reach the stores. Some people think that the temperature has an effect on the ripening of bananas. This experiment will be testing

well in shortage. A group of researchers‚ observed this common problem in the society. The researchers wanted to unveil an experiment that was long forgotten by the society. The study is about methane gas that was produced by using a raw product‚ Banana peels. The researchers discussed this experiment because the researchers observed that many people are complaining to the government about the price hike of the gasses. The researcher’s objective is to strengthen this study and to give the readers
