🗑
|
||||
| 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
🗑
|

🗑
|
||||
| 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.
🗑
