Transcript

Briefly talk with students about how humans use
plants to protect the soil, provide fresh air, and
create visual interest. Ask the students if they
have thought about plant parts that they eat. As
a class, brainstorm edible plant parts. List them
either on the chalkboard or on an overhead
transparency. After the students have either
exhausted their ideas or you think the list is long
enough, give each student a copy of WS–A. Have
them work in pairs or small groups to identify
which category (flowers, fruits, leaves, roots,
seeds, or stems) they think each of the foods
belong.
1
Identify the parts of a plant.
2
Understand the function of each plant part.
3
Identify the plant parts that are used for
human consumption.

Problem: What are the
main parts of a plant?
I.
There are six main parts of a
plant. Each part is important to the
plant’s survival.
A.
Flower
B. Fruit
C. Leaf
D. Root
E. Seed
F. Stem
Anticipated
Problem: What is the
function of each part of a plant?
II.
Each part of the plant has a
specific job to do. Without even one
of these parts, the plant, as a
whole, would not be able to survive.
 A.
Flower—The flower is the reproductive
organ of the plant that produces seeds.
The flower may also attract insects for
pollination, if necessary.
 B.
Fruit—The
fruit is the
part of the
flowering
plant that
contains the
seeds.
 C.
Leaf—The
leaf is the
food factory
of the plant.
The leaves
use
chlorophyll,
water,
sunlight, and
carbon
dioxide to
make food.
D.
Root—The
root is the
anchor of the
plant. The
roots also
absorb and
carry water
and nutrients
from the soil.
 E.
Seed—The seed contains an embryo
that provides food and water until the
plant is able to make food for itself.
F.
Stem—The
stem holds the
leaves and
flowers of the
plant. Tubes in
the stem
transport food
and water from
the roots.
Anticipated
Problem: What plant
parts do humans eat?
III.
The fruits, vegetables, and spices
that we eat are parts of plants.
Many times people incorrectly
identify the part of the plant they
are eating.
A.
Some examples
of flowers that
humans eat are
broccoli,
cauliflower,
artichokes, and
whole cloves.
 B.
Some examples
of fruits that
humans eat are
apples, grapes,
avocados,
pumpkins,
cucumbers,
tomatoes, and
eggplants.
C.
Some examples of leaves that
humans eat are cabbage, lettuce,
Brussels sprouts, spinach, oregano,
and basil.
 D.
Some
examples of
roots that
humans eat
are beets,
carrots,
radishes,
turnips, and
rutabagas.
 E.
Some examples of seeds that
humans eat are peas, beans, corn,
sunflower seeds, nuts, rice, peanuts,
and popcorn.
 F.
Some examples of stems
that humans eat are
celery, mushrooms,
onions, potatoes,
asparagus, cinnamon, and
yams.

of a plant?
