| Question | Answer |
|---|---|
| What organelle makes proteins | ribosome |
| is facilitated diffusion passive transport or active transport | passive |
| do prokaryotic cells have ribosomes | yes |
| what type of transport through the cell membrane requires energy | active |
| name two things pro and eukaryotic cells have in common | Dna,Cytoplasm,ribosomes,and cell membrane |
| what does isotonic mean | equal amount of solutes |
| what organelles in a plant have to do with energy | mitochondria and chloroplast |
| what does the word hypertonic mean | higher levels of solutes |
| name three organelles that are involved in producing or processing proteins | Rough ER, Golgi, Ribosome and nucleus |
| Are plant cells pro or eukaryotic. | eukaryotic |
| Why do phosopholipids form a phospholipid form a bilayer | the heads are hydrophillic and the tails are hydrophobic |
| give 2 reasons why cells must be small | DNA overload and surface area/xolume ratio |
| where is dna found in a eukarotic cell | nucleus |
| what do lysosomes do | break down waste |
| wil a cell in a hypertonic solution shrink or swell. | shrink |
| what is one reactant of photosynthesis | water,co2 |
| what is one product of photosythesis | glucose and oxygen |
| where does photosynthesis take place | chloroplast |
| do plants undergo celluar respiration | yes |
| where does celluar respiration take place in eukaryotic cells | mitochondria |
| which organelle is an extension of the nucleuar envelope | ER |
| what two forms of energy are involved in photosynthesis | light and chemical energy |
| what is one reactant of celluar respiration | glucose and oxygen |
| what is one product of celluar respiration | water co2 and ATP |
| why are pants green | red and blue light is absorbed green lightis reflected |
| why do we breathe oxygen | we need it for cellular respiration |
| what are the 4 phases of the cell cycle | g1 s g2 m |
| what happens during the s phase | dna makes a copy of itself |

| what word means diffusion of water | osmosis |
| what is the difference between facilitated diffusion and trnasport that requires a protein pump | facilitated does not use energy protein does |
| define diffusion | the movement of a higher concentration to a lower |

| name two structures found in animal cells but not in plants | lysosomes and centrioles |
| does exocytosis require energy | yes |
| what are 3 examples of active transport | protein pump, exocytosis and endocytosis |
| what structure in the cell helps maintain homeostasis in the cell | cell membrane |
