Biology Lesson Plan
Parts of a Plant
College Students
Overview
Objectives
Standards1

Students will use a computer and headphones to listen
to a verbal lesson about different parts of a plant.
 Given a diagram, students will identify various parts
of a plant using a diagram to correctly label with parts
with 100% accuracy.
 Given a multiple choice quiz define functions of
various plant parts by selecting the correct answer
from a multiple choice question with 100% accuracy.
PS.2.10

Contrast the biochemistry and functions of plant cell
membranes and cell walls. Describe the structural roles of
cellulose and other compounds in the primary and secondary
walls, the role of pectin in the middle lamella, the fluid mosaic
model of the membrane, and the role of the cell membrane
proteins in transporting materials in and out of cells.
S.2.11

Explain the roles of the vacuole and cell wall in controlling
cell turgor. Describe the phenomena of osmosis and turgor
pressure, predict the direction that water will move given the
concentrations of solutes in adjacent cells, and demonstrate the
proper use of terms associated with turgor such as turgid,
flaccid, hypertonic and hypotonic.
S.2.12

Describe the genomes in a plant cell's nucleus, plastids and
mitochondria.
S.2.13

1
Compare and contrast photosynthesis and respiration.
Recognize that animals perform only respiration, while plants
perform both photosynthesis and respiration. In addition,
identify the plant organelles that perform each process,
contrast the equations of the two processes, using both words
and chemical formulae, contrast the source of energy for each
process, describe the role of ATP in each process, and describe

how hydrogen ion gradients are produced and can be used as
an energy source in many cellular processes.

Diagrams
Before doing this activity, students should know the
following information:
The basic parts of a plant
The functions a plant performs
Why this functions are important
First have the students write down a list of functions a
plant performs and fill out a diagram of the plant
parts.
Then, have the students listen to the verbal lesson
while looking at the diagram.
Next, have the students fill out another diagram and
add their list of functions so they have a nice list.

axil - the angle between the upper side
of the stem and a leaf, branch, or
petiole.
axillary bud - a bud that develops in
the axil.
flower - the reproductive unit
of angiosperms.
flower stalk - the structure that
supports the flower.
internode - the area of the stem
between any two adjacent nodes.
lateral shoot (branch) - an offshoot of
the stem of a plant.
leaf - an outgrowth of a plant that
grows from a node in the stem. Most
leaves are flat and contain chloroplasts;
their main function is to convert energy
from sunlight into chemical energy
(food) through photosynthesis.
node - the part of the stem of a plant
from which a leaf, branch, or aerial
root grows; each plant has many
petiole - a leaf stalk; it attaches
the leaf to the plant.
root - a root is a plant structure
that obtains food and water from
the soil, stores energy, and
provides support for the plant.
Most roots grow underground.
root cap - a structure at the ends
(tips) of the roots. It covers and
protects the apicalmeristem (the
actively growing region) of the
root.
stem - (also called the axis) is the
main support of the plant.
tap root - the main root of some
plants; the tap root extends
straight down under the plant.
terminal bud - a bud located at
the apex (tip) of the stem.
Terminal buds have special
tissue, called apical meristem,
consisting of cells that can divide
nodes. Label the two lower nodes (the
first and second nodes) on the plant
diagram.
Evaluations

indefinitely.
Students will hand in their first and second diagram
they filled out
 Students will have a quiz the following week over the
material
