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

Science 9 Chapter 5.1 The Cell Cycle and Mitosis Pg152-158 Notes Cell Replacement and Development -Cells continue to divide as you continue to grow. -Muscle & nerve cells usually do not continue to divide in adult. The Cell Cycle -Life of cell = divided into 3 stages called cell cycle. -Stages = Interphase‚ Mitosis and Cytokinesis -Interphase= cells carry out functions necessary for survival and cells that divide prepare for reproduction. -Mitosis divides duplicated contents of cell’s nucleus

The Xylem is part of a plant‚ which is a hollow tube with spiral thickening of lignin around the wall giving strength‚ which is continuous throughout the whole plant. The difference between the Xylem cell and other cells is that the Xylem is dead and has no cytoplasm. The Xylem is responsible for transporting water and certain nutrients form root to plant. Phloem carries soluble organic material i.e. food for the plant. The top of the plant is in the light‚ conducting photosynthesis and helping the

Sickle cell anemia is an inherited blood disease that means you are born with it and it lasts a lifetime. People with sickle cell anemia inherit two variant or sickle cell genes‚ one from each parent. In the United States‚ sickle cell anemia affects about 72‚000 people. About 2 million Americans carry the sickle cell trait but about 1 in 12 African Americans have the trait. The signs and symptoms of sickle cell anemia are different in each person. Some people have mild symptoms; others have very severe

The Genome Project (~92% complete): • 20‚000-28‚000 genes in the human genome o The genome was found using a shotgun sequence. o 10% of the genome is Long Intersperse Nuclear Elements (=LINEs). This leaves the questions as to which part of the genome are LINEs? 80‚000-120‚000 proteins in a cell. 200‚000-2

ASSIGNMENT - Why is a cell microscopic? By Lachlan Bryant This research assignment will discuss why cells are usually microscopic in size‚ given that they need to be able to exchange material with their surrounding environment. The cell is highly organised with many functional units or organelles (Spurger).A membrane is a fluid mosaic which consists of proteins‚ lipids and carbohydrates which seperates the cell from it’s surrounding environment or subdivides a cell into specialised regions or

imagine how life would be without cell phones. Very few people don’t comprehend how much that would affect us. At one point in life people used to mail each other letters to get messages back and forth from one person to another. In this current century those methods has been added to the cell phones. Research Question: How have cell phones changed us socially? How have cell phones impact our lives? Source: South University Online This article showed how cell phones impacted our lives today
