| Question | Answer |
|---|---|
| what is within a plant cell | cell wall, cell membrane, nucleus, chloroplast, ribosomes, mitochondria, vacuoles, and cytosol |
| what is cytoplasm | organelles and cytosol (not nucleus) |
| what is the cell theory | all living things are made of cells, cells are the basic unit of life, new cells come from pre-existing cells |
| all living things are made of cells, cells are the basic unit of life, new cells come from pre-existing cells | glucose+ ozygen-> water, carbon dioxide, and energy |
| function of nucleus? | nucleus controls cell's activities and contains DNA |
| function of chloroplast? | photosynthesis and contains chlorophyll |
| whats found in plant cells but not animal cells | cell wall, chloroplast, and vacuole |
| whats the role of respiration in cells | turns glucose into energy |
| how are new cells produced? | mitosis |
| how many times does a cell split when dividing | twice |
| what are the organs for the digestive system | oral cavity, esophagus, stomach, small intestine, large intestine, rectum, anus |
| what organs also relate to digestive | liver, gallbladder, pancreas |
| what is the function of a liver | processes nutrients absorbed form small intestine and drugs+ produces bile to digest lipids |
| processes nutrients absorbed form small intestine and drugs+ produces bile to digest lipids | stores bile and releases into small intestine |
| function of pancreas | produces digestive enzymes and produces insulin |
| whats the function of the digestive system | breaks down food into nutrients on a cellular level for the body to absorb and use for energy. also removes waste |
| what are the organs within a circulatory system | heart, arteries, arterioles, capillaries, venioles, veins |
| how does the blood flow (heart) | right atrium -> superior and inferior vena cava -> right ventricle ->the pulmonary artery to get oxygenated by the lungs -> pulmonary vein into the left atrium -> gets pumped out by the left ventricle through the aorta |
| what is the order of organs for respiratory system | nasal/oral cavity, trachea, pharynx, larynx, bronchi, bronchioles, alveoli |
| technology that relates to body systems | stem cells that can be used to treat patients who need bone marrow transplant |
| what is within chloroplast | chlorophyll (makes plants green) |
| what is the role of insulin | helps sugar to be absorbed from the bloodstream into the cells of the body |
| what is the role of bile | helps with digestion |
