QuestionAnswerHelp
ATP (Adenosine triphosphate) An organic compound, C10H16N5O13P3, that is composed of adenosine and three phosphate groups. It serves as a source of energy for many metabolic processes. ATP breaks "D"own to ADP for energy!
Chlorophyll The green pigment found in the plants and in cells of photosynthetic microorganisms (e.g. photosynthetic bacteria), which is primarily involved in absorbing light energy for photosynthesis. GREEN-color-o-fill
Chloroplasts Chlorophyll-containing plastid found within the cells of plants and other photosynthetic eukaryotes. Plate with GREEN-o-fill
Product a substance obtained from another substance through chemical change to produce through change=product
Reactants any substance that undergoes a chemical change in a given reaction starting substance=Re-ACT-ants
Stomata small holes in the epidermis of leaves, stems, etc., where gases are exchanged. Stomata=Stow-away matter (gas) from plants' holes.
Transpiration the passage of water through a plant from the roots through the vascular system to the atmosphere. trans-pass water from plants- to gas- in air =transpire
Activation Energy The least amount of energy required to start a chemical reaction. Minimum to Activate
Carbohydrates Any of a class of organic compounds, saccharides or, if they are relatively small, sugars. Are a major source of metabolic energy, both for plants and for animals that depend on plants for food. Carbos (sugar) give energy to humans!
Enzymes Proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. EN (prefix)means to intensify.i.e. enzymes-enraged the reaction time(speed up)making the required activation energy lower.
Lipids Any of a group of organic compounds that are greasy to the touch, insoluble in water, and soluble in alcohol and ether: lipids comprise the fats and other esters with analogous properties and constitute, with proteins and carbohydrates, the chief structur lipid-SLIPid-GREASY
Nucleic Acids Any of a group of long, linear macromolecules, either DNA or various types of RNA, that carry genetic information directing all cellular functions: composed of linked nucleotides. Sends signals to direct life! Made up of nitrogenous base + five-carbon sugar + phosphate group.
pH A symbol for the measure of the acidity or alkalinity/base of a solution. Scale 0-14, H2O being neutral=7, Acids=0 , base/alkaline=14.
Proteins Any of numerous, highly varied organic molecules constituting a large portion of the mass of every life form and necessary in the diet of all animals and other nonphotosynthesizing organisms, composed of 20 or more amino acids linked genetically. Protein=Amino-meat-mass
Aerobic Occurring in the presence of oxygen or requiring oxygen to live. In aerobic respiration, which is the process used by the cells of most organisms, the production of energy from glucose metabolism requires the presence of oxygen. Aero=air=oxygen; in the presence of Aero!
Photosynthesis A chemical process by which plants trap light energy to convert carbon dioxide and water into carbohydrates (sugars). photo means light-to make food with light.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
