GROUP 6 ANIMAL CELL and It’s Functions ANIMAL CELL: About animal cell usually have an irregular shape. are eukaryote cells‚ or cells with a membrane bound nucleus. DNA is housed within the nucleus. Also contain other membrane bound organelles‚ or tiny cellular structures that carry out specific functions necessary for normal cellular operation. smaller than plant cells. Cell Membrane is the outermost component of a cell. it is composed of 55% proteins‚ 25% phospholipids

Question: With the aid of specific examples‚ describe the concept of a hierarchy of biological organization. What is meant by the phrase “the whole is greater than the sum of its parts?” Answer: In an attempt to appreciate the world from a biological view of molecules‚ cells‚ and atoms; the study in which these properties build upon each other‚ called emergent properties‚ aid in understanding the human body and other life forms and the functions that nonliving matter contribute that assist

for letting people in and letting people out. Golgi Bodies- In cells‚ structures called Golgi Bodies are stacks of membrane-covered sacs that package and move proteins to the outside of the cell. Golgi bodies are the packaging and secreting organelles of the cell. Analogy- In a restaurant to-go boxes are made to take food outside of the restaurant. Vacuole Membrane- This is the thin layer that separates the vacuole from the cytoplasm. This thin membrane allows materials to move in and

involved in the movement of substances into and out of cells. Epithelial cells – Epithelial cells are also referred to as eukaryotic cells. These types of cells have a unique nucleus and contain membrane-bounded organelles. Epithelial cells absorb and secrete‚ and the structures of a cells organelles can be viewed from an electron microscope. The nucleus – the nucleus of a cell contains most of the cell’s genetic material‚ organized as multiple long linear DNA molecules in complex with a large variety

which we observe today. Dr Margulis received evidence from all over the world and from many scientific researchers and experiments‚ Margulis simply had to put all the evidence together to form her hypothesis. Margulis states that the eukaryote cell organelles‚ mitochondria as well as the chloroplast in plants‚ arose from simple prokaryote organisms which formed an endosymbiotic relationship with the early eukaryote cells. Prokaryotes are believed to be the first inhabitants of the earth‚ they are primitive

M4A1 Midterm Essay BIO110 Excelsior College 1. You are the biologist in a group of scientists who have traveled to a distant star system and landed on a planet. You see an astounding array of shapes and forms. You have three days to take samples of living things before returning to earth. How do you decide what is alive? If three days is all I have to take samples of living things‚ then it would be very hard to determine what is truly alive‚ as the time restriction only allows for certain

Cell Structure I. Cell History A. Anton Leewenhock (1600s) - first person to observe cells - in pond water‚ using a homemade microscope B. Robert Hooke (1665) - observed many kinds of animal tissue under a microscope - concludes that all animals are made up of cells C. Schwann (1868) - observed many kinds of animal tissue - concludes that all animals are made up of cells D. Schleiden (1869) - observed many kinds of plant tissue - concludes that all plants are made up of cells E. Cell

eukaryotic cells is incorrect? A) The lack of organelles in prokaryotes means that they are structurally less complex than eukaryotes. B) The lack of internal membranes means that prokaryotes cannot compartmentalize function to the same extent as eukaryotes. C) All membrane function in prokaryotes is accomplished in the plasma membrane‚ while in eukaryotes‚ these functions are more distributed among the organelles. D) The specialization of function in organelles suggests that eukaryotes will contain a
