Lesson Overview:
1) What do we already know? (Diversity of Organisms)
2) Vocabulary
3) Drawings
4) Main Ideas
5) Review
Plant Structures and Functions: Lesson 1
Vascular Plants:
What do we already know?
BrainPOP Teaser
1) What important things do plants provide for
people?
• Oxygen
• Food
Plant Structures and Functions: Lesson 1
Vascular Plants: Vocabulary Part I
1) Seed: contains an undeveloped plant, stored food and a protective
covering
2) Spore: is a single cell that can develop into a new plant that is exactly
like the one that produced it
3) Angiosperm: a vascular plant that has seeds and produces flowers
(exm: fruits, vegetables, flowers…)
4) Gymnosperm: a vascular plant that has seeds but DOES NOT produce
flowers (exm: evergreens or pine trees)
5) Pollination: the process in which the male and female cells of plants
come together
Plant Structures and Functions: Lesson 1
Vascular Plants: Drawings (pg. 73)
• Types of Vascular Plants
•Seedless
•Use spores to reproduce
•Seed
•Flowers (Angiosperms)
• No Flowers (Gymnosperms)
Plant Structures and Functions: Lesson 1
Structure of a Flower
Plant Structures and Functions: Lesson 1
Reproduction Cycle of a Flower
BrainPOP
Vascular Plants: Main Ideas
1) What are vascular plants?
1) Plants that have tubes
2) They can be seedless or have seeds.
 Quick Check
-Critical Thinking: What kind of vascular
plant is an apple
tree? Flowering plant (angiosperm)
Plant Structures and Functions: Lesson 1
Vascular Plants: Main Ideas
2) How are seedless and seed plants
different?
•
•
Seedless plants have spores
Seed plants have seeds in flowers or cones.
 Quick Check
-Sequence: How do seed plants develop?
List the steps for each
Plant Structures and Functions: Lesson 1
Vascular Plants: Main Ideas
3) What do flowers do?
•
•
Attract pollinators to spread pollen.
Provide seeds for the reproduction cycle
 Quick Check
-Sequence: What are the steps of pollination?
Plant Structures and Functions: Lesson 1
Vascular Plants: Review
1) Summarize the main ideas
1) Click to Watch!
2) Vascular plants are divided into 2 groups
1) Seedless
2) Seed
3) Reproduction Cycle of a Flower
1)
2)
3)
4)
5)
Transfer of pollen from one plant to another
Pollen travels down the pistol
Pollen & egg cell come together to create a seed
The plant then dies and drops its seeds
A new plant grows in its place.
