Photosynthesis
Entails photosynethesis related questions
| Question | Answer |
|---|---|
| Nutrition | The study of nutrients in food, how the body uses them and the relationship between diet, health, and diseases |
| 2 types of nutrition | 1) Autotrophic 2) Heterotrophic |
| Autotrophic | Organisms that make their own food using inorganic substances |
| Heterotrophic | Organisms that depend on other organisms to produce their food |
| 3 types of heterotrophic nutrition | 1) Holozoic Nutrition 2) Saprophytic Nutrition 3) Parasitic Nutrition |
| Layers of the internal structure of the leaf | 1) Upper Epidermis 2) Palisade Layer 3) Spongy Layer 4) Lower Epidermis |
| What part of the vascular bundle is the xylem vessel located | The upper part |
| Function of waxy cuticle | Prevents water from evaporating from the leaf |
| Plural of Stoma | Stomata |
| Function guard cells | Responsible for opening and closing the stoma |
| Why are the palisade mesophyll cells arranged like fence? | To maximize light absorption |
| Where does the most photosynthesis occur | Palisade Layer |
| Why are spongy cells loosely packed? | For efficient gas exchange |
| Function of xylem vessel | Carries water and minerals |
| Function of phloem tubes | Carries away food that the leaf has made |
| Photosynthesis | Process by which green plants make their own food usine inorganic substances |
| Worded and Chemical Equation of Photosynthesis | Carbon dioxide + Water Sunlight/Chlorophyll----> Glucose + Oxygen 6CO2 + 6H2O sunlight/chlorophyll-----> C6H12O6 + 6O2 |
| Where does the light dependent stage take place | Thylakoid of the chloroplast |
| (T or F) Chlorophyll does not trap energy from the sun | F |
| Molecule high in energy | Atp (Adenosine Triphosphate) |
| What splits water molecules into hydrogen and oxygen? | Energy |
| What process is use to rid oxygen as a waste product from the leaf? | Diffusion |
| Another name for Light Independent Stage | Calvin Cycle |
| What happens in the Light Independent stage? | Enzymes are used to combine hydrogen with carbon dioxide to make glucose |
| List 3 internal Leaf Adaptions | 1) Stomata present in lower epidermis to allow gas in and out 2) Air spaces in lower leaf aloow carbon dioxide to get to chloroplasts 3)Chloroplast is more abundant in cells in palisade layer, located at the top part of the leaf, closest to sunlight |
| Uses of Glucose | 1) Broken down during respiration to release energy so plan can carry out life processes 2) Converted to starch and stored in the leaf 3) Converted to sucrose and transported to other parts of plant |
| List the Limiting Factors in Photosynthesis | 1) Temperature 2) Light Intensity 3) Carbon Dioxide Concentration 3) Availability of water |
