| Question | Answer |
|---|---|
| The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. It has three main parts: the membrane, nucleus and cytoplasm. | Cell |
| Any of a number of organized or specialized structures within a living cell. | Organelle |
| A substance that provides nourishment essential for growth and the maintenance of life. | Nutrients |
| To throw away or discard. | Dispose |
| A material, substance, or byproduct) eliminated or discarded as no longer useful or required after the completion of a process. | Waste |
| Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. | Cellular Process |
| In biology, the structure in a cell that contains the chromosomes. This structure has a membrane around it, and is where RNA is made from the DNA in the chromosomes. | Nucleus |
| The study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring. | Genetic |
| To bring under control. | Regulate |
| An organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth. | Chloroplast |
| 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. | Mitochondria |
| A membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. | Vacuole |
| Intentionally choosing some things and not others: | Selective |
| A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. During this process, water and carbon dioxide combine to form carbohydrates (sugars) and give off oxygen. | Photosynthesis |
| Something that blocks the way. | Barrier |
| To make possible, practical, or easy. | Enabled |
| To discharge | Expelled |
| The firm nonliving layer that encloses and supports the cells of most plants, bacteria, fungi, and algae. | Cell Wall |
| Consisting of a single cell. | Unicellular |
| something having many related parts that function together as a whole. : an individual living thing. | Organism |
| A large group of single-cell microorganisms. Some cause infections and disease in animals and humans. | Bacteria |
| A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, aerobic respiration, and oxidative metabolism. | Cellular Respiration |
| Found in all cells and separates the interior of the cell from the outside environment. This consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell. | Cell Membrane |
| An organism composed of many cells, which are to varying degrees integrated and independent. | Multicellular |
