plant Transport system Flashcards
(21 cards)
Transport
a system or means of conveying people or goods from place to place by means of a vehicle, aircraft, or ship.
phloem
the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
xylem
the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem.
cortex
the outer layer of the cerebrum, composed of folded gray matter and playing an important role in consciousness.
vascular system
The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body.
vascular bundle
a strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.
stem
the main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean.
leaf
a flattened structure of a higher plant, typically green and blade like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.
stomata
a flattened structure of a higher plant, typically green and blade like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.
photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
chloroplast
a plastic that contains chlorophyll and in which photosynthesis takes place..
chlorophyll
a green pigment, present in all green plants and in antibacterial, responsible for the absorption of light to provide energy for photosynthesis.
root
the part of a plant that attaches it to the ground or to a support, typically underground, conveying water and nourishment to the rest of the plant via numerous branches and fibers.
root system
The configuration of a plant’s various roots. See more at fibrous root, taproot.
taproot
a straight tapering root growing vertically downward and forming the center from which subsidiary rootlets spring.
fibrous root
A fibrous root system is the opposite of a taproot system.
absorb
take in or soak up (energy, or a liquid or other substance) by chemical or physical action, typically gradually.
anchor
a heavy object attached to a rope or chain and used to moor a vessel to the sea bottom, typically one having a metal shank with a ring at one end for the rope and a pair of curved and/or barbed flukes at the other.
drought
a prolonged period of abnormally low rainfall; a shortage of water resulting from this.
adapt
make (something) suitable for a new use or purpose; modify.
phototropism
the orientation of a plant or other organism in response to light, either toward the source of light ( positive phototropism ) or away from it ( negative phototropism ).
