Selective barrier (choose what crosses) What cells have a cell membrane? all cells DAILY DOUBLE Purpose of the cell wall. protection and support Information that controls the cell is Always located here nucleus Organelle that synthesizes proteins. ribosome The building units of polymers. monomers Organelle that releases energy from food to make ATP mitochondrion The reactants of photosynthesis. Carbon dioxide, water, light Reactants of cellular respiration Sugar and oxygen The cell’s charged battery. ATP adenotriphosphate When cells surround and take in solid particles. phagocytosis The role of chlorophyll Capture sun’s energy and excite the electrons of water Besides the central vacuole, two organelles that are found in plants but not animal cells. Cell wall chloroplast Part of the molecule that has the energy. Bonds between electrons Main difference between prokaryote and eukaryote cells. Prokaryotes have no nucleus Besides cell membrane, what organelle do both prokaryotes and eukaryotes have? Ribosome Water is special because it can form these. Hydrogen bonds Having a high specific heat means water does this Holds its temperature well This element makes a compound organic carbon How many valence electrons does Carbon have? 4 Type of reaction that joins monomers into polymers Dehydration synthesis The main component of the cell membrane phospholipid This strong carbohydrate is the main Component of Cell walls cellulose Speeds up chemical reactions Catalyst (enzymes) How do catalysts speed up the cell’s reactions? By lowering activation energy
