| Question | Answer |
|---|---|
| What is the function of the nucleus? | Holds the chromosomes |
| What is the function of the nucleolus? | Make ribosomes |
| What is the function of the chromosomes? | Responsible for growth and reproduction |
| What is the function of the Endoplasmic Reticulum? | Transport proteins |
| What is the function of the Golgi Body? | Package proteins |
| What is the function of the Ribosomes? | Make Proteins |
| What is the function of the Cytoplasm? | keep organelles from bumping into each other (fluid that fills the cell) |
| What is the function of the Vacuole? | Store waste, material, and water |
| What is the function of the Lysosome? | To clean the cell of old organelles and waste |
| What is the function of the chloroplast? | Site of photosynthesis |
| What is the function of the Cell Membrane? | Control what goes in and out of the cell |
| What is the function of the Cell Wall? | Stiff outside covering on a plant cell that provided support |
| What is the function of the Mitochondria? | Break down sugar for energy |
| How does the vacuole in the plant cell look different than in the animal cell? | Plant cell vacuole is larger and only has one |
| What is the process that plant do to make sugar (food), that animal cells cannot do? | Photosynthesis |
| What is on the outside of a plant cell, but not on an animal cell? | Cell wall |
| What do eukaryotic cells have that prokaryotic cells do not? | A nucleus |
| What are two examples of eukaryotic cells? | Plants and animals |
| What are the two types of prokaryotic cell? | eubacteria and archaebacteria |
| What are the prokaryotic cells that live in extreme environments? | extremophiles- heat loving, salt loving, and methane making |
| What was Leuwenhoek's discovery? | Single celled organisms in pond water |
| What was Hooke's discovery? | Discovered and named cells |
| What was Pastuer discovery? | Disproved Spontaneous Generation |
| What was Schleiden discovery? | Discovered all parts of Plants are made of Cells |
| What was Schwann discovery? | Discovered all parts of Animal are made of cells Cells |
| What was Virchow discovery? | Discovered that cells come from pre-existing cells, but took this discovery from another scientist. (May have borrowed the idea :-) |
| What are the three parts of the cell theory? | All living things are made of cells. Cells are the basic unit of life. All cells come from pre-existing cells. |
| Define Osmosis | The movement of water from a high concentration to a low concentration through a semi-permeable membrane. |
| Define Diffusion | The movement of molecules from a high concentration to a low concentration. |
| Define Semi-permeable | Lets some things through but not others. |
| What is the stage of the cell cycle where the chromosomes copy? | Interphase |
| What is the stage of the cell cycle where the chromosomes go to the center of the nucleus and look like spaghetti? | Prophase |
| What is the stage of the cell cycle where the chromosomes line up and there is no longer a nucleus? | Metaphase |
| What is the stage of the cell cycle where the chromosomes pull to opposite ends of the cell? | Anaphase |
| What is the stage of the cell cycle where the two groups of chromosomes are grouped into two new nuclei? (Two nucleus in one cell) | Telophase |
| What is the stage of the cell cycle where the cell splits into two daughter cells? | Cytokinesis |
| What is the most common cell on Earth? | Bacteria (Eubacteria) |
| What type of cell is Bacteria? | Prokaryotic |
| What is the order of the stages for the cell cycle? | Interphase, prophase, metaphase, anaphase, telophase, cytokinesis |
| What was Remack's discovery? | Discovered that all cells come from pre-existing cells and actually did all the work for this discovery. |
| Which CLT is.. “My dog has become much less clumsy now that he is a year old.” | Grow and develop |
| Which CLT is... "A giraffe uses its long neck to eat from the high branches of a tree." | Adaptation |
| Which CLT is... "A hydra (pond creature) breaks off one of its tentacles and that tentacle becomes a new hydra." | Reproduction |
| Which CLT is.. “Single-celled organisms live in the pond behind school.” | Made of Cells |
| Which CLT is... “When that car pulled in the driveway, my cat ran to hide under the porch.” | Respond |
| Which CLT is... "Mushrooms do not do photosynthesis, but they do decompose material for nutrients." | Use and Obtain Energy |
| What is sexual reproduction? | 2 parent organisms, offspring is a combination of the two parent's DNA, happens in multicellular organisms. |
| What is asexual reproduction? | 1 parent organism splits into two identical daughter cells. Offspring are genetically identical. Happens quicker than sexual reproduction. |
| What is an advantage of asexual reproduction? | Happens quickly |
| What is an disadvantage of asexual reproduction? | What can injure or kill one cell (parent cell) can injure or kill the copies (daughter cells). |
| What is an advantage of sexual reproduction? | Since offspring are combinations of the parents they can adapt and survive more situation. |
| What has to happen before a cell can divide? | Duplicate (copy) the chromosomes (DNA) |
| What is an disadvantage of sexual reproduction? | Takes longer than asexual reproduction. |
| What does unicellular mean? | one celled or single celled |
| What does multicellular mean? | many celled |
| What is the main difference between Eukaryotic and Prokaryotic cells? | Eukaryotic cells have a nucleus, Prokaryotic cells do not |
