Question | Answer |
Inorganic | does not contain carbon |
Interphase | longest part of the cell cycle
DNA replicates and the cell prepares to divides |
Active Transport | energy is needed to move substances into or out of the cell |
Anaphase | Chromosomes separate and move toward end of spindle. |
Lipids | fats, store energy for later use |
Metaphase | chromosomes line up in the middle of the cell |
Atom | basic part of an element |
ATP | form of energy released during respiration |
Autotroph | makes its own food |
Carbohydrates | energy rich organic molecules (sugar and starch) |
Cell cycle | life cycle of a cell |
Centriole | forms end of spindle during mitosis |
Centromere | holds chromatids together |
Chlorophyll | green pigment in plants |
Chloroplast | organelle that stores chlorophyll |
Chromatid | single strands held together by a centromere |
Chromosome | contains genetic information, made of DNA |
Compound | made up of two or more elements that are chemically combined |
Concentration | the amount of substance in a solution |
Cytokinesis | when a cell splits into two after mitosis |
Daughter cells | new cell resulting from mitosis, identical to parent |
DNA | molecules that make up chrosomes |
Element | pure substance; cannot be broken down into simpler substances For example, Oxygen and hydrogen |
Enzymes | chemicals that speed up chemical reactions |
Fermentation | energy releasing process - may produce alcohol of lactic acid |
Glucose (C6,H12,O6) | Sugar produced during photosynthesis |
Heterotroph | eats other things for food. For example, humans |
Impermeable | when membrane acts a barrier to substances |
Mitosis | process of cell division |
Molecule | smallest part of a compound |
Nitrogen Bases | A, T, G, C make up the rungs of the DNA |
Organic | contains carbon |
Passive transport | no energy needed to move substances in or out of the cell |
Parent cells | starting cell in mitosis |
Permeable | allow substances to pass freely through |
Photosynthesis | energy storing process (energy from the sun in stored in glucose) |
Pigment | colored substance. For example, chlorophyll absorbs light |
Products | Substances produced by chemical reactions |
Prophase | first phase of mitosis - Nucleus breaks down; spindle forms |
Protein | make up cell parts - form enzymes are organic compounds |
Reactants | the ingredient or raw materials for a reaction |
Replication | process in which DNA copies itself |
Respiration | energy releasing process- uses 02 to release energy from glucose |
Selectively permeable | allow something to pass through, but not others |
Spindle | during mitosis, chromosomes attach to it |
Stomata | openings on under side of leaf |
Telephase | phase of mitosis in which the nuclear membrane reappears |
