Transport in the Xylem of Plants
The loss of water vapor from the stems and leaves of plants
What is transportation
The living tissue that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular, the sugar sucrose, to parts of the plant where needed.
What is phloem
Tissues in a plant consisting of undifferentiated cells capable of indeterminate growth
What is meristems
These are the three main steps in plant reproduction.
What is Pollination, Fertilization, and Seed Dispersal.
Pores on the underside of the leaf which facilitate gas exchange (needed for photosynthesis)
What is Stomata
Tissue in vascular plants that helps provide support and conducts water and nutrients upward from the roots
What is Xylem
Long and narrow cells that are connected together to form tubes
What is sieve tubes
Give rise to primary growth (lengthening) and occurs at the tips of the roots and shoots
What is apical meristems
These are three main ways that plant can reproduce.
What is Vegetative propagation, Spore formations, Pollen transfer
The part of the seed that stores food and nutrients.
What is the Cotelydon
As water molecules move up the xylem via capillary action, they pull inward on the xylem walls to generate further tension
What is adhesion in xylem
Provide metabolic support for sieve element cells and facilitate the loading and unloading of materials at source and sink
What is companion cells
Hormone that is pumped to areas where growth is needed.
What is Auxin
Name one specialized condition some seeds need for germination.
Fire, digestion, freeze, scarring, washing
Transport vessels that combine to form a vascular bundle in higher order plants
What are Xylem and phloem
Causes water molecules to be dragged up the xylem towards the leaves in a continuous stream
What is Transpiration Pull
Areas where sugars and amino acids are loaded into the phloem
What are sources
Plants growing toward a light source is called this.
What is Phototropism
These are the 4 condition needed for germination to occur.
What is Oxygen, Water, Temperature, pH
The region in which Plant growth is initiated.
What is meristems
Plants that can tolerate dry conditions (such as deserts) due to the presence of a number of adaptations
What is Xerophytes
Where the sugars and amino acids are unloaded and used
What are sinks
A technique used to produce large numbers of identical plants (clones) from a selected stock plant
What is Micropropagation
This is the hormone that triggers germination in seeds.
What is Gibberellin
The phytochome triggers flowering in most plants.
What is pFR
