Xylem
These structures provide structure to prevent tubes from collapsing.
What are lignin helices
This is the substance that flows through phloem
What is sap?
This hormone controls plant growth patterns
What is auxin
This structure releases pollen
What is an anther
These are plants that are adapted to dry environments
What are xerophytes
This is the pressure conditions that xylem transport water in
What is tension?
These are cells that load phloem
What are companion cells?
This is the tendency for plants to grow according to light
What is phototropism?
This is the structure that generates pollen
What is the anther?
This is the family of plants that has the highest number of species
What are orchids?
These are the cells that open and close the pores on leaves
What are guard cells?
This is the direction that glucose and nutrients flow in phloem.
What is from sources to sinks?
This is the tissue type that is responsible for plant expansion.
What is a lateral meristem?
This structure of plants allows for vegetative propagation
What is a stolon
This is the term for a plant that grows on top of another plant
What is a epiphyte?
This is the main factor that drives the flow of water in xylem
What is transpiration
These are cells that actually transport material as the phloem vascular tissue
What are sieve tubes?
This is the term for adding new cells to the end of a root
What is elongation?
This is a method for distributing new embryos far from parent plants
What is seed dispersal?
This is the term for farmers altering the amount of light available to a plant to induce growth changes
Flower forcing
These leaf pores are where gas exchange occurs
What are stomata
Relative to xylem, phloem is typically located in this direction.
What is cortical
This is the tissue that lies between xylem and phloem in dicot vascular bundles
What is the vascular cambium?
This is the method for moving male gametophytes to the stigma of another plant
What is pollination?
This is the term for attaching a bough of a plant onto a stem of a plant of a different species
What is grafting?
This is what happens when air is able to enter xylem through tissue damage
What is a cavitation?
This is a modified root structure that stores sugars
What is a tuber?
This is the property of cells that can differentiate to any tissue type
What is totipotent?
This is the dominant generation of plants with flowers
What is a sporophyte?
This is the term for intentionally destroying a band of phloem
What is girdling?
This is the method by which plants intake water into their roots
What is osmosis?
This is the form of sugar that is commonly used as storage because of it's insolubility
What is starch?
This is the balance between growth of primary stems vs axillary stems
What is apical dominance?
This is an embryonic tissue that will become a root
What is a radicle?
This is any tissue in a stem that isn't otherwise named
What is ground tissue
These are structures also known as root hairs
What are trichomes?
These are the holes between cells in phloem that allow the transport of material
What are plasmodesmata?
This is a pluripotent form of meristem
What is a floral meristem?
This class of chemicals is involved in ending seed dormancy
Gibberellins
These plants have xylem but no style
What are ferns?
