plant nutrition B5 Flashcards
photosynthesis
carbon dioxide + water > glucose + oxygen
glucose in plants
store of energy
part of plant that is responsible for photosysthesis
chloroplasts
thing that does the photosynthesis in the chloroplasts
chlorophyll
what effects the rate of photosynthesis
light intensity, amount of carbon dioxide, temp
name the leaf structure from the upper layer
cuticle, upper epidermis, palisade mesophyll layer, spongy mesophyll layer, lower epidermis
role of cuticle
prevents evaporation and blocks other substances entering the epidermis layer
role of upper epidermis
transparent layer that lets the light reach the palisade layer for photosynthesis
role of palisade mesophyll layer
contains the most chloroplasts, and main layer that photosynthesis
role of spongy mesophyll layer
storage of sugar and amino acids produced from the palisade mesophyll layer
role of lower epidermis
allows carbon dioxide enter the leaf, and excretes oxygen and the excess water.
stomata
opens and closes due to water flowing in and out. allows gas exchange
2 minerals that are required grow plants
magnesium, nitrate
what happens when the plant lacks nitrates
stunned growth and yellow leaves
what happens when the plant lacks mgnesium
leaves turn yellow
