Cards (25)

Xylem- It transports water and minerals in an upward direction.
Shoot System - Parts of a plant that are found above the ground.
Root System - Parts of a plant that are found below the ground.
Auxin - Promotes cell growth and elongation of the plant.
Abscissic acid (ABA) - Regulates plant growth, development, and stress responses.
Cytokinin (CK) - Promotes seed development, cell expansion, cell differentiation, and nitrogen assimilation.
Brassinosteroids (BR) - Promotes cell division, expansion, elongation, development, and immunity.
Ethylene (ET) - Stimulates the opening of flowers, fruit ripening, and immunity.
Gibberellins (GA) - Stimulate cell elongation and cause plants to grow taller; response to nutritional limitation.
Growth Promoters - A growth promoter stimulates plant growth, enhancing processes such as cell division and elongation.
Growth Inhibitors - A growth inhibitor suppresses plant growth, often through factors like environmental stress or allelopathic substances.
Nectarine - Phytohormones released by certain trees that attract insects such as red ants.
Pit - Allows water transport.
Vessel Element - Dies as a plant matures, causing dip hollows in trees.
Tracheids - As thin as hair.
Translocation - Moves the sugar in the phloem to the parts that need it.
End of Dormancy Period - The plant withers due to the onset of a new season.
Growing Period - Parts of plants that were sugar sinks become the sugar sources.
Surface Tension - Forms between hydrogen molecules.
Adhesion - Molecular attraction between unlike molecules.
Cohesion - Molecular attraction in like molecules.
