Cells and Energy
Prokaryotes, Eukaryotes, Photosynthesis and Cellular Respiration
| Term | Definition |
|---|---|
| Photosynthesis | Conversion of RADIANT energy into CHEMICAL energy. |
| Cellular Respiration | Conversion of CHEMICAL energy to CHEMICAL energy |
| Glucose | Chemical energy, product of photosynthesis, also known as SUGAR |
| ATP | Chemical ENERGY made during cell respiration |
| Reactants | elements or compounds that we START with to create products |
| Products | elements or compounds that are made/ created from reactants |
| Mitochondria | organelle found in eukaryotes that uses glucose to make ATP |
| Chloroplast | organelle found in autotrophic eukaryotes (Plants/some Protist) that makes glucose |
| Products of photosynthesis | oxygen and glucose (sugar) |
| Products of cellular respiration | carbon dioxide, water, and ATP |
| Non-membrane bound organelles | have NO membrane Ex: ribosomes |
| Membrane- bound organelles | have a membrane Ex: nucleus, chloroplast, mitochondria, vacuole |
| Prokaryotic cells | Small, simple, always unicellular, loop DNA, NO Nucleus and NO membrane bound organelles |
| Eukaryotic cells | Larger, complex, with nucleus, membrane bound organelles, and linear DNA. Can be unicellular or multicellular. |
| Flagella | tail-like structure that helps cells move around, can be present on BOTH PRO and EUK |
| Cilia | hair-like structure that helps cells move around, can be present on EUK only |
| Cell membrane (phospholipid bilayer) | maintains homeostasis by allowing molecules in and out of the cell (semipermeable), in BOTH PRO and EUK |
| Cell wall | Provides extra protection and support, Can be found in BOTH: -PRO: some bacteria -EUK: plants and some protists |
| Cytoplasm | Gel like material where reactions occur, in BOTH PRO and EUK |
| Ribosome | Where proteins are made, the only non-membrane bound organelle, in BOTH PRO and EUK |
| Nucleus | hold the DNA (genetic material), EUK cells ONLY |
| Vacuole | store water and some waste, larger in plants, EUK cells ONLY |
