with correct answers | |
What is transpiration? - Correct answer ✔The loss of water vapor through the
| | | | | | | | | | | | |
stomata of leaves. | |
What is the lumen? - Correct answer ✔inside tubular space of thylakoids
| | | | | | | | | | |
What is the cuticle - Correct answer ✔a waxy covering of the epidermis
| | | | | | | | | | | |
what is the stoma? - Correct answer ✔opening in leaves that allows for gas
| | | | | | | | | | | | | |
exchange, controlled by guard cells | | | |
What is photorespiration? - Correct answer ✔When RuBisCo binds to oxygen
| | | | | | | | | | |
instead of carbon dioxide. Opposite of photosynthesis.
| | | | | |
epidermis - Correct answer ✔skin under cuticle of leaves
| | | | | | | |
palisade mesophyll - Correct answer ✔Layer of tall, column-shaped mesophyll
| | | | | | | | | |
cells just under the upper epidermis of a leaf. column shape lets in more light
| | | | | | | | | | | | | |
spongy mesophyll - Correct answer ✔lower layer of loose tissue in leaf; has
| | | | | | | | | | | | |
many air spaces between its cells
| | | | |
, Difference in conc. gradient between CO2 and H2O - Correct answer ✔conc.
| | | | | | | | | | | |
difference driving CO2 into leaf is 100x smaller than that driving H2O vapor out
| | | | | | | | | | | | |
What closes guard celles? - Correct answer ✔darkness, drought, cold,
| | | | | | | | | |
pathogens, ABA hormone | |
What opens guard cells? - Correct answer ✔light, low CO2 inside, Auxin
| | | | | | | | | | |
Where does the dry weight in a plant come from? - Correct answer ✔air
| | | | | | | | | | | | |
How do guard cells work? - Correct answer ✔When needed to open, ions are
| | | | | | | | | | | | | |
pumped into guard cells, water follows in which swells cells and the pressure
| | | | | | | | | | | | |
opens stoma. When needed to close, ions low out, followed by water and
| | | | | | | | | | | | |
decreased pressure closes stoma. | | |
What are the two parts of photosynthesis? - Correct answer ✔light reactions
| | | | | | | | | | | |
and calvin cycle
| |
Light reactions - Correct answer ✔requires light energy
| | | | | | |
Makes ATP & NADPH | | |
Releases O2 (PART THAT USES WATER) | | | | |
Calvin Cycle - Correct answer ✔(synthesis)
| | | | |
Takes in O2 and makes G3P which is turned into sugars
