Leaf Structure Flashcards
What Structure attaches the leaf to the stem of a plant?
Petiole
The Monstera deliciosa plant is pictured below. It is easily recognizable for what reason?
the large holes/gashes in the leaf blade
What is the primary job of leaves?
to gather sunlight for photosynthesis
_______are tiny pores in leaves that are responsible for gas
exchange for photosynthesis. They are surrounded by__________open and close the pore.
stomata, guard cells
What ENTER’S the leaf through an open stoma.
carbon dioxide
What EXIT’S the leaf through an open stoma.
oxygen and water
The evaporation of water out of an open stoma is called______________
Transpiration
When do guard cells close stomata?
when the plant loses too much water, at night and when photosynthesis needs to stop.
When the guard cells open the stoma, they absorb water causing them * 4 points swell and bow outwards. The guard cells are said to be ________________
Turgid
Without ground tissue in LEAVES, the plant….
Cannot do photosynthesis
If the plant has no xylem, then the plant…
cannot transport water
If the plant has no phloem, then the plant…
Cannot transport sugar/glucose
If the plant has no stoma, then the plant…
cannot perform gas exchange
If the plant’s stoma remain open, then the plant…
will undergo too much transpiration
