plant process

sol 7.5

TermDefinition
photosynthesis the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
respiration a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
stomata Image result for define stomata in biology Tiny openings called stomata allow plants to exchange gases necessary for cellular processes, such as photosynthesis.
guard cells each of a pair of curved cells that surround a stoma, becoming larger or smaller according to the pressure within the cells.
chlorophyll a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
chloroplast (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
light dependent reaction The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH.
light independent reaction The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose.
energy pyramid An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain.
producer An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy)
mitochondria an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
autotrophs an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
consumers An organism that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food from inorganic sources; a heterotroph.
herbivore an animal that feeds on plants.
omnivore an animal or person that eats food of both plant and animal origin
heterotrophs an organism deriving its nutritional requirements from complex organic substances.
carnivore an animal that feeds on flesh
decomposers an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. a device or installation that is used to break down a chemical substance.
spongy layer a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis -- called also spongy parenchyma, spongy tissue.
palisade layer a layer of parallel elongated cells below the epidermis of a leaf.
raw materials the basic material from which a product is made.
oxygen colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
carbon dioxide a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.
glucose a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates. a syrup containing glucose and other sugars, made by hydrolysis of starch and used in the food industry.
product in chemistry, a product is a substance that is formed as the result of a chemical reaction. In a reaction, starting materials called reactants interact with each other.

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.
