SOL LS.2 - CELLS
| Term | Definition |
|---|---|
| HYPOTHESIS | A POSSIBLE EXPLANATION FOR A SET OF OBSERVATIONS OF AN ASNWER TO A SCIENTIFIC QUESTION |
| CELLS | THE FUNDAMENTAL BUILDING BLOCKS OF LIVING THINGS |
| CELLULAR RESPIRATION | A SERIES OF CHEMICAL REACTIONS IN WHICH CELLS CONVERT AND RELEASE ENERGY FROM FOOD MOLECULES TO A USABLE FORM (ATP) AND GIVE OFF WASTE |
| CHLOROPLASTS | ORGANELLES IN THE CELLS OF STEMS AND LEAVES THAT CONTAIN A PLANT'S CHLOROPHYLL, NECESSARY FOR PHOTOSYNTHESIS |
| CYTOPLASM | A JELLYLIKE SUBSTANCE THAT HOLDS THE CELL'S PARTS IN PLACE, GIVES THE CELL ITS SHAPE, AND IN WHICH MANY CHEMICAL REACTIONS OCCUR |
| DIFFUSION | THE NET MOVEMENT OF SUBSTANCES OTHER THAN WATER, FROM AN AREA OF HIGH CONCENTRATION TO ONE OF LOW CONCENTRATION |
| LAW | A PREDICTION OF WHAT WILL HAPPEN IN A WAY THAT CAN BE EXPRESSES WITH MATH. IT IS BASED ON OBSERVATION |
| MEIOSIS | A SPECIAL TYPE OF CELL DIVISION THAT PRODUCES REPRODUCTIVE GAMETES, WHICH CARRY HALF THE GENETIC MATERIAL OF EACH PARENT |
| MITOCHONDRIA | ORGANELLES IN A CELL'S CYTOPLASM WHERE CHEMICAL ENERGY IS RELEASED IN A FORM THAT CELLS CAN USE |
| MITOSIS | THE DIVISION OF A SINGLE CELL INTO TWO NARLY IDENTICAL CELLS, EACH CONTAINING THE SAME GENETIC CONTENT AS THE ORIGINAL CELL |
| NUCLEUS | A MEMBRANE-ENCLOSED AREA WITHIN A EUKARYOTIC CELL, SOMETIMES CALLED THE CELL'S BRAIN. IT PROTECTS THE CELL'S DNA, WHICH DIRECTS ALL THE CELL'S ACTIVITIES, INCLUDING GROWTH AND METABOLISM |
| ORGANELLES | THE SPECIALIZED PARTS WITHIN THE CELLS OF LIVING EUKARYOTIC ORGANISMS THAT WORK TOGETHER IN A SYSTEM TO TAKE IN FOOD, GET RID OF WASTE, AND REPRODUCE. EACH HAS A DIFFERENT SHAPE AND JOB TO DO |
| OSMOSIS | THE PASSIVE NET MOVEMENT OF WATER MOLECULES FROM AN AREA OF HIGHER TO LOWER WATER CONCENTRATION (OR LOWER TO HIGHER SOLUTE CONCENTRATION) ACROSS A CELL MEMBRANE |
| PHOTOSYNTHESIS | THE CHEMICAL PROCESS BY WHICH A PLANT CONVERTS SUNLIGHT, CARBON DIOXIDE, AND WATER INTO GLUCOSE (A SUGAR) AND OXYGEN. GLUCOSE ENABLES THE PLANT TO GROW AND REPRODUCE, AND OXYGEN KEEPS MANY PLANTS AND ANIMALS ALIVE |
| THEORY | A WAY TO DESCRIBE PATTERNS WE REPEATEDLY SEE IN NATURE. THEORIES RELY ON INFERENCE AND TRY TO EXPLAIN HOW SOMETHING HAPPENS |
| CELL MEMBRANE | THIS THIN, FLEXIBLE ENCLOSURE IS THE GATEKEEPER FOR THE CELL |
| VACUOLES | THE STORAGE BINS OF THE CELL. THEY HOLD NUTRITENTS, WATER, AND EVEN WASTE |
| PERMEABILITY | THE STAE OR QUALITY OF A MATERIAL OR MEMBRANE THAT CAUSES IT TO ALLOW LIQUIDS OR GASES TO PASS THROUGH IT. |
