Life & Cells

Life & Cells Living Envrionment regents Review

QuestionAnswer
Active transport The process by which cells use energy to transport molecules through the cell membrane from areas of low concentration to areas of high concentration
Amino acids Any one of several building blocks of proteins
Cell The basic unit of structure and function that make up all organisms
Cell membrane The thin boundary between the cell and its environment
Cell respiration The process in which nutrients are broken apart, releasing the chemical energy stored in them
Chloroplast The green organelle that contains chlorophyll; where photosynthesis takes place
Circulation The flow of materials within a cell as well as between parts of a multicellular organism
Cytoplasm The jelly like substance that is between the cell membrane and the nucleus and that contains specialized structures
Diffusion The movement of molecules from areas of concentration to areas of low concentration
Digestion The process that breaks down large food molecules that the organism can use
Enzymes Proteins that speed up the rate of chemical reaction in living things
Excretion The removal of all the wastes produced by the cells of the body
Homeostasis The ability of an organism to maintain a stable internal environment even when the external environment changes
Hormone A chemical produced in the endocrine glands
Immunity The bodys ablilty to destroy pathogens before they cause disease
Inorganic a type of molecule that does not contain both carbon and hydrogen but can contain any other combination of elements.
Metabolisim All the chemical reactions in your body
Mitochondria Organelles that contain enzymes to turn glucose into energy in the form of ATP. Used in cellular respiration
Nucleus Large cell organelle that contains DNA is is the cells control center
Organ Body structure made of tissues
Organ System Several organs that work together to preform a major body function. (Digestive, Circulatory, Respriatory, Nervous, Endocrine, Reproductive, Integumentary, Muscloskeletal)
Organelle Cell structure that carrys out a cellular function.
Organic Molecules that contain Hydrogen and Carbon. (molecules that are used in living things)
Receptor Molecule Protein molecules on the cell membrane that can send and recieve signals from other cells.
Reproduction Process by which organisims produce more organisms of the same type
Respiration The cellular process where glucose is used to make energy (ATP) releasing carbon dioxde (CO2)
Ribosome Cell organelle that is used for protein synthesis
Simple Sugar The monomer of carbohydrates results from the digestion of starches. (glucose)
Synthesis Life process that involves combining simple molecules into more complex molecules. (to make or produce)
Tissue A group of specalized cells that preform a function
Vacoule Organelles that store things, Typically water. Plants cells have a large central vacoule
Photosynthesis The cell process where chloroplasts capture light energy and use it to turn carbon dioxide (CO2) into glucose (C6H12O6)
Chloroplast Cell organelle that is the site of photosynthesis (it looks like a bean full of pancakes)
Glucose Organic molecule used by living things to make energy (ATP). Produced during Photosynthesis. (C6H12O6)
Gas Exchange The process living things taking in oxygen and releasing carbon dioxide. Or vise versa
Characteristics of life (life proceses) Life process that are used to describe if somthing is "alive" In order to be alive you must be able to 1 - Reproduce, 2- Grow and Develop, 3 - Respond to stimuli , 4 - use energy , 5 - Made of cells, 6- Maintain homeostasis

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.

To see how well you know the information, try the Quiz or Test activity.
