Lecture 5 (Ch. 23 )
1.What are the 2 types of apical meristems and how do
Root contains rootcap, underground
Shoot where growth is taking place, flower
2.What is the difference between an initial and a
Initials never d
1. What is a tropism and what is the difference between a
positive and a negative tropism? What are the different
A tropism is a growth response of bending/curving of a plant part
toward or away from an external stimulus.
Lecture 3 (Ch. 20)
1.When did Angiosperms first appear in the fossil
Cretaceous (130 million years ago).
2.When did we first see the modern families of plants
75 million years ago.
3.What are three tools we use to classify the
Lecture 6 (Ch 24)
1.What are the primary functions of a root?
Anchorage, absorption, conduction, storage, synthesis of
some hormones and secondary metabolites.
2.What is the primary root?
First root that originates in the embryo.
3.What is the difference
1. What defines an element as an essential element to
needed for plant to complete its life cycle
It is part of any molecule/constituent that is essential to
(deficiency symptoms appear if element is absent)
2. What molecules do pla
1. How can a hormone cause 2 different effects in the same
plant? (hint sensitivity and transduction pathways)
Differences with plants - may act within tissue where they were
may stimulate/ inhibit
Often times occur in inactive
Ch 31 and 32 Questions
1. Describe the different soil horizons. Which is closest to
the surface of the Earth?
A horizon is alive with roots, insects and small arthropods, nematodes
and decomposer organisms.
Subsoil is a region of deposition. Iron oxide, c
Lecture 2 (Ch. 19)
1.Monocotyledon or Eudicotyledon?
a. A plant has flowers with 15 pedals and netlike
A eudicot would have 15 pedals (they usually grow in 4s
or 5s), and they have netlike leaf ventilation.
b. An oak tree (secondary growth)
Lecture 1 (Ch. 1)
1.What is the importance of photosynthesis in present
times and from a historical perspective?
Photosynthesis provides most of the atmospheric oxygen
which is vital for respiration of plants and animals. In a
historical sense, photosynth
Lecture 4 (Ch. 22 )
1.What is the difference in the apical-basal pattern
and the radial pattern of plant development?
Apical-basal pattern of embryogenesis grows top to
bottom, while the radial pattern grows outward.
2.Embryogenesis is the process of what
1. What group of plants did seed plants most directly
2. What is a steel and where do we find each of the 3
Stele - central cylinder of pith and primary vascular tissues.
1) Protostele - solid cylinder of v
Evolution of the Angiosperms
in fossil record early in Cretaceous (at
least 130 million years ago)
dominated global vegetation by 90

modern families and genera by 75

The Process of Evolution

natural (or artificial) selection
The Process of
importance of population size
changes may occur rapidly
Autotrophs sustain themselves without consuming
organic matter derived from other organisms
Producers feed most of the living world
Almost all plants are photoautotrophs, using the
energy of sunlight to make organic molecules from H2O

*The breakdown of organic molecules is exergonic
Aerobic respiration consumes organic molecules and O2
and yields ATP
Anaerobic respiration is similar to aerobic respiration but
consumes compounds other than O2
