Each unit of stem that consists of a leaf, axillary bud and internode is referred to as a phytomere. Note that axillary buds always occur above a leaf. Axillary buds give rise to branch shoots. Thus, branching in a shoot system is exogenous (of external origin). How does this compare to branching in a root system?

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 an adventitious root? In a monocot rhizome such as that of irises and bamboo, are adventitious roots common or rare? If a bamboo rhizome grows 100 feet underground and then sends up an aerial branch, where does that branch get its water—from the roots 100 feet away or from adventitious roots right at its base
Why are terminal buds considered an active part of the stem? Of what importance are nodes to the plant? What are inter nodes and where are they located?
What would happen if you removed the shoot apical meristem of a plant? -The plant would grow several lateral shoots -Growth would only occur at in the roots. -The plant would mature, but only through vertical growth--no branches would form. -The root apical meristem would take over the function of the shoot apical meristem.
Why are some roots called Adventitious Roots?
The following model is considered what root? Eudicot or Monocot
Which of the following statements is incorrect? a. Vascular bundles are arranged in a ring in the outer parts of monocot stems in whereas in eudicots they are scattered throughout the stem. b. The cuticle is a hydrophobic layer that covers the aerial part of plants c. Vascular bundle arrangement is different in stem and root. d. The epidermis and periderm form the dermal tissue of plants.
As plants grow, they tend to align theirstems and roots along the direction of the gravitational field. This tendency, which is related to differential concentrations of planthormones known as auxins, is referred to as gravitropism. As an illustration of gravitropism, experiments show that seedlings placed inpots on the rim of a rotating turntable do not grow in the verticaldirection. Do you expect their stems to tilt inward—toward the axisof rotation—or outward—away from the axis of rotation?
Because secondary phloem is formed from the vascular cambium just as secondary xylem is, it too has an __________________________ system and a _____________________ system. Why do the size, shape, and number of phloem rays match those of xylem rays?
From the viewpoint of the plant, can you suggest a practical reason for branch roots originating internally instead of at the surface?
Why are some roots called adventitious roots? What root system best adapted for anchorage? Why do you say so? Which among the root system is most advantageous to the plant? Explain your answer.
Plants grow through division of________ cells and differentiation of the resulting daughter cells. Thesedividing cells reside in two locations: at the tip of a shoot orroot, called the______ , and in cylinders along thesides of roots and stems, called________ . Which is responsible for primary growth?_______ Which is responsible for secondary growth?_________
