Cells to Organisms
Unit 3 Review Part III (Microbes, Matter & More)
| Question | Answer |
|---|---|
| What is a prokaryote? | a single-celled organism without a nucleus or organelles |
| What is a eukaryote? | a single or multi-celled organism with a nucleus |
| Are Eubacteria and Archaebacteria prokaryotes or eukaryotes? | prokaryotes |
| Are animals, plants, fungi, and protist prokaryotes or eukaryotes? | eukaryotes |
| What best describes bacteria? | a unicellular organism that has a cell wall but lacks a nucleus and other organelles |
| What best describes protists? | Any single-celled eukaryotic (has a nucleus) organism that does not fit in the animal, plant, or fungi family |
| What best describes a virus? | A non-living infectious agent consisting of genetic material and a protein coat and only able to multiply inside a living host |
| Are viruses considered to be living things? | No; they are not made of cells and cannot reproduce on their own (only with a host cell) |
| What is a vaccine? | A preparation that is used to stimulate the body's immune response against diseases |
| How could you define energy? | The ability to cause an object to change, move or work |
| Food breakdown releases these two things. | Matter and energy |
| What process is explained by glucose + oxygen = carbon dioxide + water + energy? | Cellular respiration |
| Do all living things go through cellular respiration? | Yes! |
| What is photosynthesis? | The process by which plants convert water and carbon dioxide into sugars and oxygen |
| What process is explained by sunlight + water + carbon dioxide = sugar (glucose) + oxygen? | Photosynthesis |
| Where do plants get energy for photosynthesis? | the sun |
| Do plants or animals have larger vacuoles? | Plants |
| Which cell parts do plants have that animals do not? | Chloroplasts and cell wall |
| What is an antibiotic? | Chemicals that kill living microbes, such as bacteria, by breaking down the cell wall |
| What is cellular respiration? | A process that provides energy needed by cells and releases carbon dioxide as waste |
| What is matter? | Physical substances that make up all living and nonliving objects. Carbon dioxide, oxygen, and sugars are all examples of matter |
| What type of diseases do antibiotics work against? | Bacteria |
| What is an epidemiologist? | a scientist who trace the spread of a disease through a population |
| What is an incubation period? | time between getting infected with the disease and the appearance of symptoms |
| What is an example of an antibiotic? | Penicillin |
