Chapter 28, Problem 5TY
Summary Introduction
Introduction:
New leaves are formed due to leaf primordia that are a group of cells. These new leaves are formed at the shoot tip and resembles to inverted cones. Further, there is flower primordia as well from which flower develop. Flower primordia is basically a little flower bud.

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?
Examine the shoot system of a mature plant (Coleus blumei). Identify the shoot tip, nodes, internodes, leaves, and axillary buds. 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?
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.
O Apical meristemic tissue is only found in woody plants.
