Cell Biology (PCB 3023) Fall 2012 Review for Exam 1 Chapter 1 List the key commonalties and differences between prokaryotic and eukaryotic cells. Prokaryotic – no organelles; no nucleus; bacteria and Achaea; spherical‚ rodlike/corkscrew-shaped; cell wall; Eukaryotic – has nucleus; has organelles Commonalities – contain DNA that stores genetic information What is the main component of cellular membranes? What function(s) do membranes serve in cells? Made of phospholipids; defines

Cell Membrane The Cell Membrane- The cell membrane is a semi-permeable membrane that surrounds the cytoplasm of a cell; the cell membrane is made up of phospholipids‚ proteins and carbohydrates. Its function is to protect the integrity of the interior of the cell allowing certain substances into the cell‚ while keeping other substances out. The phospholipids form a thin‚ flexible sheet while the proteins float in the phospholipid sheet like an ice berg‚ and the carbohydrates extend out from the

In Crash Course video number four you learn animal cells and how they operate more like a city. Hank calls this city Eukaryopolis- The city of animal cells. He also goes over what each part of the cell and how the animal cells are responsible for different things that happen in our body. The very start of video starts off comical by showing you the difference between what an animal is and is not. Then it goes on to explain that why a eukaryotic because they have a “true kernel‚ meaning good nucleus

Background Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy? ACTIVE Which CELL PART provides the energy for

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

Animal Cell Song I’m here to talk to you about animal cells. They are made up of many organelles. Chromosome‚ nucleus‚ those are a few They need them to live like me and you. Well we’ll start with the nucleus the “command center.” It’s the brain of the cell and keeps it away from danger. It’s a safe haven for the chromosomes. They store DNA like our own. The precious DNA carries our genes. Genes tell the cell what to do like info. machines. Now let’s talk about the mitochondrion

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into
