Learn about plant body. [Leaf]
(identification) Leaves are the ________ anf CO2 collectors of plants
Solar energy
(identification) Joins the leaf to a stem node.
Petiole
(identification) have parallel major veins
Monocots
(identification) Multi branched network of major veins
Dicots
(identification) [Leaf Arrangement] Leaves at a node, on opposite sides of stem.
Opposite
(identification) [Leaf Arrangement] 1 leaf per node, with the second leaf being above the first but attached on the opposite side of the stem
Alternate
(identification) [Leaf Arrangement] 3 or more leaves at a node.
Whorled
(identification) Compound leaves have several ________
Leaflet
(identification) one or few prominent midveins from which smaller minor veins branch into a meshed network.
Netted-Venation
(identification) Main vein called midrib with secondary veins branching from it.
Pinnately-veined leaves
(identification) Veins radiate out of base of blade
Palmately-veined leaves
(identification) characteristics of many monocot, veins are ….. to one another.
Parallel venation
(identification) No midrib or large veins. Fan-shaped.
Dichotomous
(T/F) Stomates are openings of the leaf and stems for fas exchange.
True
(identification) teo of these special cells surround each stomate and regulate the opening and closing of the Stomate.
Guard cells
(identification) Contain vascular tissue with that in the stem.
Veins
(T/F) Xylem Carries dissolved food throughout the plant
False, Phloem
(T/F) Function of leaf is for Photosynthesis, Gaseous exchange.
True
(identification) Phloem carries water and minerals upward
False, Xylem
(identification) Water moves from roots to stem by..
Capillary action
(T/F) Most of the water plants take up is lost to the atmosphere by condensation.
Flase, Evaporation
(identification) The evaporation of water vapor from plant surface is called…
Transpiration
(T/F) Almost all leaf transpiration results from diffusion of water vapor through the stomal pore.
True
(identification) Stomate is closed, its opening begins when ____________ enter guard cells.
Potassium ions
(identification) Water flows into guard cells by..
Osmosis
(identification) ____________ are kidney-shaped with thick inner walls and thin outer walls.
Guard cells
(identification) When the Guard cells become full of water..
Turgid
(identification) how much in percentage does it swell up.. the guard cells.
40%-100%
(T/F) Effectiveness of controlling water loss and allowing CO2 uptake for Photosynthesis is called the Transpiration Ratio
True
(T/F) CO2 diffuses 16 times slower than water
True
(identification) Accumulation of the plant hormones.. what is this hormone?
Abscisic Acid
(identification) A biochemical pathway that prevents photorespiration
The C4 carbon leaf
(enumeration) C4 leaves have 2 chloroplasts containing cells
Mesophyll cells, Bundle sheath
(identification) Where and what is the Purpose of Bundle sheath
Deep in the leaf so atmospheric oxygen cannot diffuse easily to them. Ehhh
(identification) Other name for Seed Leaves?
Cotyledons
(identification) It is the first leaves produced by a germinating seed, also storage of food.
Cotyledon
(identification) Blade of leaves or leaflets are reduced in size, allows plants to cling to other objects.
Tendrils
(identification) Scientific name of Pitcher plant.
Sarrocenia oreophila
