Question | Answer |
Name 4 of the scientists that contributed to the Cell Theory | Robert Hooke, Anton van Leeuwenhoek, Matthias Schleiden, Theodor Schwann |
Who first called cells "cells". | Robert Hooke |
How did a Dutch lens craftsman contribute to the cell Theory? What was his name? | He made the first simple microscope. Anton van Leeuwenhoek |
Who concluded that plants and animals were made up of cells? | Matthais Schleiden and Theodore Schwann |
What did Rudolf Virchow propose? | He proposed that cells can only come from other cells. |
What organelles does a plant cell have that an animal cell doesn’t have? | Chloroplasts and Cell Wall |
If you were given a slide containing living cells of an unknown organism, describe how you would identify the cells as either plant or animal. | See if there is a Cell Wall |
What organelle is most involved in diffusion, osmosis, and active transport? | Cell Membrane |
Which has a higher concentration of water: 200 ml of water with 10 grams of sugar or 200 ml of water with 50 grams of sugar? | 200 ml of water with 10 grams of sugar. |
In the osmosis egg lab, which had a higher concentration of water in it: the egg or corn syrup? Which way did the water diffuse? | Egg. From egg to corn syrup. |
What had a higher concentration of water: the egg or the distilled water? Which way did the water diffuse? | Distilled water. From distilled water to egg. |
What are the 4 main Elements that make up living things? 5th and 6th? | Carbon, Hydrogen, Oxygen, Nitrogen. Phosphorus, Calcium. |
What are the 4 main Molecules that make up living things? | Proteins, Carbohydrates, Lipids, and Nucleic Acids |
Which molecule has the most energy? | Carbohydrates |
Where is the energy stored in the molecule? | The bonds. |
Photo means “light” and synthesis means “combining together”. What molecules does light energy help combine together in photosynthesis? | 6 Water and 6 Carbon Dioxide. |
What new molecules are synthesized in photosynthesis? | Glucose and 6 Diatomic Oxygen Molecules |
In what organelle does photosynthesis occur? | Chloroplast |
Where does all the matter in a tree come from? | Water |
Write out the entire photosynthesis equation. | 6H2O + 6CO2 = C6H12O6 + O6 |
What pigment is in plants that give them their green color? | Chlorophyl. |
What color light does this pigment reflect? | Green |
What colors does it absorb? | Red and Blue. |
What is the purpose of cellular respiration? | Break down the glucose molecule so it can be used as energy. |
In what organelle does cellular respiration occur? | Mitochondria |
What are the reactants of cellular respiration and what are the products? | The reactants are Glucose and Oxygen. The products are Carbon Dioxide and Water. |
Write out the entire cellular respiration equation. | C6H12O6 + O2 --> 6H2O + 6CO2 |
Do plants undergo the process of photosynthesis? Cellular respiration? | Yes. Yes. |
Do animals undergo the process of photosynthesis? Cellular respiration? | No. Yes. |
What are the 3 stages of the cell cycle? | Interphase, Mitosis, and Cytokinesis |
What happens during interphase? | The cell grows and develops and does its functions. Toward the end of interphase, the amount of chromosomes double. |
What happens during mitosis? | The nucleus duplicates itself, each with a complete set of chromosomes. |
What happens during cytokinesis? | The cytoplasm and organelles divide into 2 daughter cells. |
Which of the 3 stages takes the least amount of time? Why? | Cytokinesis. It does the least. |
Which takes the most time? Why? | Interphase. Interphase is when the cell does all its functions. |
Write in order all of the cell cycle stages. | Interphase, Mitosis, Cytokinesis. |
What happens after the last stage? | The daughter cells start their own cycles, starting with interphase. |
In which stage do the chromosomes double? | Interphase. |
In the division of somatic (body) cells, why do the chromosomes double? | The chromosomes double so the daughter cells can both have a complete set of chromosomes. |
What is the final product of the cell cycle? | The cell cycle results in two daughter cells with identical sets of chromosomes. |
