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

The Cell Theory The Cell Theory‚ formed by Anton van Leeuwenhoek‚ Robert Hooke‚ Matthias Schleiden‚ Theodore Schwann‚ and Rudolf Virchow‚ refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure‚ function‚ and organization in all organisms; and all cells come from pre-existing‚ living cells. The formation of the cell theory
Premium Cell Organism Theodor Schwann
simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic cells are more complex than prokaryotes; the major difference between the eukaryotic and prokaryotic cells is the nucleus. The nucleus in a eukaryotic cell is

surface area of a beetroot (Beta Vulgaris) piece? Background The membrane consists of a phospholipid bilayer which is semi permeable. Osmosis is the passive movement of water molecules from an area of high water potential to an area of low water potential across a semi-permeable membrane. It is easy for water molecules to pass through this membrane however solutes that are big in size may find it hard to as the semi-permeable membrane is selective to the smaller particles. This may cause a change in

contains a red pigment called betalain‚ which is in the cell vacuole. Normally the betalain stays inside the cell‚ however when the cell is exposed to extreme temperatures they leak out. The reason why they leak out is because of the cell membrane structure. When the cell membrane is exposed to extreme heat the proteins unravel and the lipids melt. This will allow the betalain to leak out from the cell vacuole. Under extreme cold the cell membrane will freeze and fracture also allowing the betalain

solutions with varying concentrations of sodium chloride on the red blood cells of sheep by measuring the transmittance of a red blood cell/NaCl solution with a spectrometer. This is done in order to study the effects of solutions containing varying levels of tonicity to red blood cells. Tonicity describes what happens to a cell when it is placed in a certain solution. Hypertonic solutions contain a lower solute concentration than the cell cytoplasm‚ hypotonic solutions contain a higher solute concentration

Animal cells vs. Plant cells Five Similarities Animal and plant cells have many of the same characteristic. Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA‚ as well as cell membrane encompassing the cell to control the substances moving in and out of the cell. They both contain enzymes from liposome for breaking down larger molecules. Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum
