What is that it controls all of the functions of the cell? Stores water in a plant cell. What is a vacuole? This tough material makes cell walls thicker and more rigid than cell membranes. What is cellulose? This green pigment absorbs sunlight. What is chlorophyll ? These are the three parts of the cell theory. What is 1. Cells are the basic unit of structure and function 2. All living things are made up of one or more cells 3. All cells come from preexisting cells? This cell part makes proteins. What are ribosomes? This is the semi-jelly like environment in which most of the cell’s activities take place. What is the cytoplasm (cytosol)? This organelle is only found in the plant cell – and provides support for the cell. What is the cell wall? This is the name of the organelle where the process of photosynthesis takes place. What is the chloroplast? White blood cells would have lots of these because their main function is to digest bacteria. What are lysosomes? This type of membrane only allows certain materials to cross it. What is an selectively permeable? Cell “eating”. What is phagocytosis? This process happens when an ink blob spreads apart from a concentrated area into area where there are fewer ink particles. What is diffusion? The movement of “water” from an area of high concentration to an area of low concentration. What is Osmosis? The type of transport requiring energy. What is active transport? This scientist was the first to use a microscope because of his great skill of grinding lenses. Who is Leewenhoek? The type of microscope we used in the lab. What is the compound light microscope? The name of the lens nearest the eye. What is the ocular lens? The part of the microscope that adjusts the amount of light through a specimen. What is the diaphragm? The total magnification when using high power on our microscopes. What is 400x ? A 40x objective times the 10x ocular lens These protein filaments keep the cytoplasm moving and aid in moving the plasma membrane. What is cytoskeleton ? Tiny finger-like projections in your small intestine increase this to allow for more efficient absorption of nutrients. What is surface area?: This allows for more efficient absorption of nutrients. The part labeled “j” on the diagram. What is a channel protein? This type of solution will cause a blood cell to shrink and lose water. What is hypertonic ? The part labeled “b” in the diagram. What is a glycoprotein? What is a phospholipid? The function of “a, b and c” in the diagram. What is cell recognition? The color of the nonpolar portion of this molecule. What is red? This is the difference between a prokaryote and a eukaryote. What is that prokaryotes do not have nuclei? The outward pressure in a plant cell when the vacuoles and cytoplasm fill up with water and push against the cell wall. What is turgor pressure?
