Chapter 6: Plant Nutrition

Question 1

Photosynthesis

Answer 1

Process where plants make carbohydrates from raw materials using energy and light.
6CO₂+6H₂0 → C6H12O6 +6O₂
carbon dioxide + water → glucose + oxygen
→ = sunlight & chlorophyll

Question 2

How plants use carbs

Answer 2

Releasing energy (respiration)
Storing
Sucrose for transport

Question 3

Transverse section of leaf

Answer 3

Upper epidermis
waxy cuticle: prevent water loss

Palisade Mesophyll
Full of chloroplast and near the top: to store max chloroplasts: max sunlight

Spongy Mesophyll
Air spaces: for gases to diffuse

Lower epidermis
Stomata: holes that open during transpiration
Guard cell: Regulate water loss and controls stomata

Vascular bundle (transports)
Xylem: Water and mineral ions
Phloem: Sucrose and amino acids

Question 4

Answer 4

Supply of raw material
Amount of sunlight
Temperature
