The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

My impact on the cycle of water Water‚ especially the use of water is normally taken for granted here in the United States. You need a glass of that cool‚ refreshing stuff; normally you would just turn on the tap and watch it flow. What would happen if when you were waiting for that crystal clear liquid to come flowing out‚ but to your surprise it doesn’t? The misuse and abuse of this natural resource has been the topic of conversations around the world. Lack of education and poor personal choices

# Cell Part Kingdom Analogy Why this analogy makes sense 1 Nucleus King The nucleus is the largest organelle and directs all cell activity‚ just like a king who controls and directs activity going on throughout the kingdom and is known as the biggest person in relation with power. 2 Nucleolus Peasants The nucleolus is the organelle which produces the ribosomes (farm) throughout the cell‚ just like the peasants who work hard to keep the farm fertile and running. 3 Ribosomes Farm The ribosomes

1. Eukaryotic cells have a true nucleus‚ bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber‚ for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell‚ because its much smaller size means that all materials within the cell are relatively close together. Of course‚ prokaryotic cells do have DNA and DNA functions. Biologists describe

Cell Transportation Lab Eggs are a great example of a cell. Underneath the hard shell is a thin membrane that is just like the cell membranes in your cells. There are microscopic pores in the membrane that allow substances to move in and out of the cell. Way Cool! Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar‚ an acid‚ to dissolve the shell off of the egg to expose the membrane

osmosis in relation to three onion cells and the impact on the cells structure. A small square of a red onion skin (membrane) was observed under a microscope at high power (X40) magnification. The observation showed a large number of onion cells. The structure of one onion cell had a general rectangular shape with a developed cell wall‚ which gives the rectangular shape to the cell and a cell membrane just beneath it. The observation under the microscope of a cell of an onion skin soaked for 15

Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine whether they have the gene(s) associated w/
