- Plants
- Starch
- only found in green parts of plants (variegated leaves do not contain them)
- "testing for starch: 1:take a leaf from a plant 2: kill in boiling water to get rid of the cuticle on the leaf which stops iodine getting through 3: remove the leaves colour with ethanol 4:wash the leaf with cold water 5: add iodine solution to the leaf (TIPS: put the leaf on a white surface to show the colour)"
- photosynthesis
- only found in green parts of plants (variegated leaves do not contain them)
- glucose
- carbon dioxide + water --> glucose + oxygen
- 6CO2 + 6H2O --> C6H126O + 6O2
- The structure of leaves
- (spongy) mesophyll
- palisade cells
- (where most of the chloroplasts are)
- Spongy cells
- Vein
- Xylem
- Transports; water and mineral ions
- Phloem
- Transports: products of photosynthesis, such as sugars
- Xylem
- palisade cells
- Lower epidermis
- Guard cells
- contains pores called stomata (single one: stoma)
- Guard cells
- the upper epidermis: the cuticle
- outer layer of cells
- the upper epidermis: the cuticle
- Lower epidermis
- Guard cells
