Question | Answer |
---|---|
CELL MEMBRANE | This flexible structure helps control what enters and leaves the cell, gives it shape, provides boundary between the cell and its environment, and helps control what enters and exits the cell. |
CYTOPLASM | a gel-like substance in which cell parts move and where many of the cell's life activities take place |
MITOCHONDRION | the energy a cell needs to carry out its activities is released from food |
NUCLEUS | a cell organelle that contains CHROMOSOMES and controls most of the cell's activities |
VACUOLE | a storage area for food, water, minerals, and wastes. |
CHROMOSOME | contains DNA |
CELL WALL | a thick outer covering located outside the cell membrane. Found in plants, algae, fungi, and some bacteria |
CHLOROPLASTS | plant cell organelles that give plants their green color and that trap energy from sunlight and turn it into food during the process of PHOTOSYNTHESIS. They contain CHLOROPHYLL. |
CHLOROPHYLL | a chemical that traps energy from the sun |
DNA | a chemical that CHROMOSOMES are made of and that is found in the NUCLEUS of every cell of all living things - the "genetic blueprint" that provides instructions for how organisms look and function. |
BACTERIA | single-celled organism |
CELL | smallest unit of life in a living thing - takes in materials and release energy and waste products |
CELLULAR RESPIRATION | process in which food and oxygen combine in the mitochondria to make carbon dioxide and water and release energy to do all of the cell's work. |
PHOTOSYNTHESIS | the food-making process of plants, green algae, and many types of bacteria; in green plants, this process occurs inside the CHLOROPLASTS, where the sun's energy and water and carbon dioxide are converted into food and oxygen. |
ORGANELLE | structure within the cytoplasm in cells that breaks down food, moves waste, and stores materials. |
ORGANISM | a living thing that has all five traits of life-it responds, moves, shows organization, reproduces, and grows and develops. |
TRAIT | a specific feature of something, such as eye color, hair color, or height. |
