Structures and related functions of a plant leaf: Leaf structures for photosynthesis Flashcards
We understand that a large surface area results in quick diffusion of gases. When dealing with leaf structures for photosynthesis, what does a large surface area also result in?
absorption
Which two tissues allow sunlight to chloroplasts in mesophyll?
transparent cuticle and epidermal cells
In which region can the moist exchange surface be located?
in the spongy parenchyma region
What does the moist exchange region in the spongy parenchyma region allow for?
quick gas exchange
Which 3 types of gases are exchanged due to regulation by the stomata?
carbon dioxide, water vapour and oxygen gas
What type of mechanism occurs when the stomata regulates the exchange of the 3 gases?
regulation mechanism
The type of transport system in a leaf structure.
vascular system
In the vascular system, what does xylem transport?
water
In the vascular system, what does phloem transport?
manufactured sugars
Name 2 ways in which intercellular spaces help at photosynthesising cells.
They help gas movement and gas exchange.
On which surface in the spongy parenchyma are cells packed?
the ventral surface
In which manner are the cells in the spongy parenchyma packed on the ventral surface?
loosely.
Are there many OR very little intercellular spaces in the spongy parenchyma?
many
In the spongy parenchyma, what is the purpose of the intercellular spaces?
for gas exchange
Are there fewer OR more chloroplasts in the spongy parenchyma in comparison to other parts of the leaf?
fewer
in photosynthesis, what is the purpose of the chloroplasts?
to capture sunlight
On which area of the leaf do the chloroplasts capture the maximum sunlight?
palisade parenchyma
Where does maximum photosynthesis occur in the leaf?
chloroplasts in mesophyll cells
