Bio Vocab Quiz
| Question | Answer |
|---|---|
| a nucleotide derived from adenosine that occurs in muscle tissue, the major source of energy for cellular reactions | ATP |
| the basic structural and functional unit of all organisms, they may exist as independent units of life or ma form colonies or tissues as in higher plants and animals | cell |
| a thin membrane enclosing the cytoplasm of a cell, proteins in the membrane control passage of ions | cell membrane |
| a rigid layer of polysaccharides enclosing the membrane of a plant and prokaryotic cells, maintains the shape of the cell and serves as a protective barrier | cell wall |
| the metabolic processes whereby certain organisms obtain energy from organic molecules, process that takes place in the cells and tissues- energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs | cellular respiration |
| any of a group of green pigments found in photosynthetic organisms; there are 4 naturally occurring forms | chlorophyll |
| a threadlike strand of DNA in the nucleus that carries out the genes in a linear order | chromosome |
| plastid containing chlorophyll and other pigments, in plants that carry out photosynthesis | chloroplasts |
| the protoplasm of a cell excluding the nucleus, is full of proteins that control cell metabolism | cytoplasm |
| the act of dispersing or diffusing something | diffusion |
| a long, linear polymer found in the nucleus of a cell and formed from the nucleotides and shaped like a double helix; associated with the transmission of genetic information | DNA |
| an organelle containing enzymes responsible for producing energy | mitochondrion |
| cell division in which the nucleus divides into nuclei containing the same number of chromosomes | mitosis |
| a part of the cell containing DNA and RNA and responsible for growth and reproduction | nucleus |
| a specialized part of the cell, analogous to an organ | organelle |
| diffusion of molecules through a semipermeable membrane from a place of lower concentration until the concentration on both sides is equal | omosis |
| allowing fluids or gases to pass or diffuse through | permeable |
| synthesis of compounds with the aid of radiant energy (especially in plants) | photosynthesis |
| an organelle in the cytoplasm of a living cell | rybosome |
| a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes, transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell | RNA |
| a membrane (as a cell membrane) that allows some molecules to pass through but not others | semipermeable membrane |
| a tiny cavity filled with fluid in the cytoplasm of a cell | vacuole |
