Plant tissues, organs and systems Flashcards
What is palisade mesophyll?
where photosynthesis occurs as contains chlorophyll
what is the upper and lower epidermis?
covers the plant
what is the cuticle?
waxy layer allows water to pass
what is the spongy mesophyll?
space for gas exchange
what is the guard cell and stoma?
where transpiration takes place
what is transpiration ?
movement of water through a plant
what are factors that effect transpiration?
- Light
- temperature
- humidity = less transpiration as water struggles to leave leaf
- wind = blowing against leaf allows more diffusion
what is the phloem ?
leaves —> roots
transports food and ions
what is the xylem ?
roots —> leaves
transports water
what is photosynthesis?
the process of water and carbon dioxide being converted into glucose and oxygen with light for enegy
what is the equation for photosynthesis?
water + carbon dioxide —> glucose + oxygen
