Which of the following hormones are NOT matched with the proper
function?
abscisic acid- promotes leaf abscission
cytokinins-stimulates cell division
ethylene- promotes fruit ripening
gibberellic acid- promotes stem elongation
auxin-promotes increases in cell size
Observe the following photos of the shoot of a monocot (left) and an eudicot (right). How are these shoots similar? How do they differ in terms of the appearance (morphology) of the leaves and the way the leaves are attached?

- What is the difference between the apical meristem and lateral meristem? shoot apical meristems lateral meristems root apical meristems Apical meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Apical meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Lateral meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristematic tissue is only found in annual plants.
