Hon Bio Ch 8 Photosy
Prentice Hall Honors Biology Chapter 8 Photosynthesis Cochran JHS
| Question | Answer |
|---|---|
| Autotrophs | organisms such as plants which make their own food |
| heterotroph | organisms that obtain energy from food they consume |
| Characteristics of ATP | an exceptionally useful molecule that is used by all types of cells as their basic energy source |
| ATP | Adenosine Tri Phosphate |
| Photosynthesis | plants use the energy from sunlight to convert water and carbon dioxide into oxygen and high energy carbohydrates - sugars and starches |
| pigment | plants gather the sun's energy with light absorbing molecules called pigments |
| Chlorophyll | the plant's principal pigment (green) |
| thylakoids | the chloroplasts contains sack-like photosynthetic membranes by this name |
| stroma | region outside the the thylakoid membrane |
| glucose | a simple sugar formed by plants during photosynthesis |
| ADP | adenosine diphosphate |
| calvin cycle | plants use the energy that ATP and NADPH contain to build high-energy compounds that can be stored for a long time |
| NADP | one of the carrier molecules is a compound known as ____ |
| light dependent reactions | use energy from light to produce ATP and NADPH |
| ATP Synthase | protein in membrane |
| The chemical reaction of carbon dioxide plus water and energy to form oxygen and sugar is called | photosynthesis |
| The reverse of photosynthesis is called ____ | respiration |
| 6 Carbon atoms, 12 Hydrogen, and 6 Oxygen atoms form a molecule of ___ | glucose |
| In what part of the cell does photosynthesis occur? | chloroplast |
| Joseph Preistly's experiment with a candle and a live plat showed that ___ | plants produce oxygen |
| Plants perform photosynthesis only when exposed to | light |
| The reactants in the photosynthesis reaction are | Carbon dioxide and water |
| The products in the photosynthesis reaction are | glucose and oxygen |
| The ultimate source of energy for plants is | light |
| _____ is like a fully-charged battery | ATP |
| ADP is converted into ___ to store energy | ATP |
| a single molecule of glucose stores more than ___ times the amount of energy in a molecule of ATP | 90 |
| ATP and glucose are both used for storing ____ | Energy |
| When you exhale, your breath contains water vapor and Carbon Dioxide which are the ___ for the photosynthesis reaction | reactants |
| ___ makes plants green | chlorophyll |
| The ___ cylcle takes place in the stroma of chloroplasts and does not require light | Calvin |
| What are the main products of the calvin cycle? | high-energy sugars |
| a waxy coating on leaves can reduce ___ ____ | water loss |
| In addition to light and chlorophyll, photosynthesis requires | water and carbon dioxide |
| chlorophyll does not absorb ___ light | green |
| Most of a growing plant's mass comes from ___ | water |
| True or False - a water buffalo is an autotroph | False |
| The light-independent reactions of photosynthesis are also known as the ___ ___ | Calvin Cycle |
| When writing out the chemical reaction for photosynthesis, the coefficents (numbers out in front of) Carbon Dioxide, water, and oxygen are all ___ but the coefficient of glucose is __ | 6, 1 |
| Amount of sunlight, amount of water, and temperature are each factors that determine the rate of | photosynthesis |
