The document introduces horticulture and identifies the basic parts of a plant. It defines horticulture as the art of cultivating fruits, nuts, vegetables, or ornamental plants. It also explains that horticulture includes floriculture, pomology, olericulture, and agronomy. The basic parts of a plant identified are the stem, leaves, roots, petals, nodes, internodes, petioles, and leaf margins.

1. Intro to
Horticulture
Mrs. Molitor

2. Today we will:
• Explain the purpose of
horticulture practices.
• Identify the basic parts of a
plant.

3. Horticulture
• The ART of
cultivating fruits,
nuts, vegetables, or
ornamental plants.
• Horti = garden
• Culture = garden

4. Floriculture
• The cultivation of
ornamental
flowering plants.

5. Botany
• The SCIENCE of
plants to include
anatomy, physiology
and taxonomy.

6. Pomology
• The science and practice of
growing, harvesting and
marketing tree fruits and
nuts.
Olericulture
• The science and practice of growing,
harvesting and marketing vegetables.

7. Agronomy
The science and practice
of grass and soils.

8. Annual
• A plant which grows, flowers,
produces seeds, and dies in
one year. Must be replanted
each year.
Perennial
• A plant that grows year after
year without replanting. A plant
whose roots lives year to year.

9. Parts of a Plant

11. The Stem:
• holds up the plant parts
above the ground.
• has tiny tubes to transport
water an nutrients to the
plant’s parts.

12. Leaves:
• Make food for plants which is
sugar
• Take in carbon dioxide
through tiny openings in the
leaves

13. Roots:
• Hold the plant in the ground
• Take in water and nutrients
for the plant’s growth

14. Petals:
• Are the colored part of the
plant

16. Let’s see what you learned:
• Which part of the plant holds
it in the ground?

17. Let’s see what you learned:
• Which part of the plant holds
it in the ground?
•Roots

18. Let’s see what you learned:
• Which part of the plant
makes food for the plant?

19. Let’s see what you learned:
• Which part of the plant
makes food for the plant?
•leaves

20. Let’s see what you learned:
• Which part of the plant holds
it above the ground?

21. Let’s see what you learned:
• Which part of the plant holds
it above the ground?
•stem

22. Let’s see what you learned:
• Which part of the plant is
usually colored?

23. Let’s see what you learned:
• Which part of the plant is
usually colored?
•petal

24. Node
• The “joint” of a stem, the
swollen place where leaves
and buds are attached. Roots
form here when cuttings are
made.
Internode
• The space between the nodes on a
stem.

26. Petiole
• The stalk structure
which supports the
blade of the leaf. It
attaches the leaf
blade to the stem.

28. Simple leaf
• A solitary leaf attached
to a stem by a petiole.
Compound Leaf
• A group of leaflets which compose the
entire compound leaf.

30. Leaf Margin
• The outer edge of a
leaf ….
• Serrate, entire,
lobed, etc.

32. Today we have…
• Explained he purpose of horticulture
practices.
• Identified the basic parts of a plant.
