Cells & Energy Test
Questions are from the review sheet
| Question | Answer |
|---|---|
| What are the six characteristics of living things? | cells, obtain and use energy, grow and develop, reproduce, respond to environment, specials chemicals. |
| converts sunlight to chemical energy. | chloroplast |
| converts nutrients to energy. | mitochondria |
| contains DNA and directs cell. | nucleus |
| membrane that surrounds and protects the cell. | cell membrane |
| non-living material that surrounds plant cell. | cell wall |
| sac that stores water, nutrients, or waste products. | vacuole |
| small structure that makes proteins. | ribosomes |
| stack of membranes that packages chemicals. | golgi bodies |
| store food or pigments. | plastids |
| jelly-like substance within the plasma membrane. | cytoplasm |
| sac filled with digestive chemicals. | lysosome |
| structure that organizes motion of chromosomes. | centriole |
| passageways where chemicals are made. | endoplasmic reticulum |
| membrane that protects the nucleus. | nuclear envelope |
| package created by the golgi apparatus. | vesicle |
| structure that manufactures ribosomes. | nucleolus |
| when your heart contracts the ventricles change size and shape. | cardiac muscle |
| when contracts arm bends at the elbow. | bicep |
| sucks in air for you to breath. | diaphragm |
| when contracts leg straightens at knee. | quadriceps |
| movement of food through the digestive system. | peristalsis |
| when ATP falls apart energy is released and sodium is pushed out and potassium is pulled in. | sodium potassium pumps |
| white bloods cells eat bacteria by wrapping it in the cell membrane and pulling it into the vesicle where the bacteria gets broken down. | endocytosis |
| hormone released from cell. hormone joins with cell membrane emptying chemical into surrounding blood stream. | exocytosis |
| when your DNA is copied into new cells that have been divided. | DNA replication |
| follows instructions from DNA. found in red blood cells. pockets that hold oxygen. Drops of oxygen at each cell. | hemoglobin production |
| made of protein called keratin. color comes from melanin. made by hair follicles. use DNA and materials from foods you have eaten to make. | hair production |
| makes more lipids to make more membranes. | lipid membrane |
| 6CO2+6H2O-C6H12O6+6O2 | six carbon dioxide molecules and six water molecules turns into glucose and six oxygen molecules. |
| 6CO2+6H2O-C6H12O6+6O2 | photosynthesis chemical formula |
| C6H12O6+6O2-6CO2+6H2O | cellular respiration chemical formula |
| where does cellular respiration happen? | in the mitochondria |
| where does photosynthesis happen? | in the chloroplasts |
| what pigment is responsible for photosynthesis? | a green pigment called chlorophyll |
