Strand III
Use Scientific Knowledge from the Life Sciences in Real-World Contexts

 

Science/Strand III
Content Standard 2
All students will use classification systems to describe groups of living things; compare and contrast differences in the life cycles of living things; investigate and explain how living things obtain and use energy; and analyze how parts of living things are adapted to carry out specific functions. (Organization of Living Things)

Science/Strand III/Content Standard 2/Elementary
Benchmark 5
Explain the functions of selected seed plant parts.

Benchmark Clarification

All plants have parts that perform a specific function (job) to keep the plant alive. Each part of a plant works to support a plant’s life.

Students will:

  • Explain how roots anchor the plant and take in water and minerals
  • Explain how stems provide support and carry water, minerals, and food to all parts of the plant
  • Explain how leaves make food (site of food production)
  • Explain how flowers produce fruit and attract pollinators (bees, birds, etc.)
  • Explain how fruits hold and disperse seeds
  • Explain how seeds carry embryos for new plants

Key Concept
Plant parts:

  • roots
  • stems
  • leaves
  • flowers
  • fruits
  • seeds

See (SCI.III.4.E.2), functions of selected animal body parts.

Real World Context
Common edible plant parts:

  • bean
  • cauliflower
  • carrots
  • apples
  • tomatoes
  • celery
  • spinach

Instructional Example

Benchmark Question: How does each part of a seed plant support the plant’s life?

Focus Question: What are the functions of seed plant parts?

Begin by reading a biography about plant expert Katherine Esau.

As a review of plant parts and their functions, have children in small groups play “Concentration” where they match a plant part card with the correct function card (link to Benchmark Clarification SCI.III.2.E.5). Lead class discussion to insure correct matches. Provide examples of foods that represent each part of a plant:

Food

Part

Function

bean

seed

carries embryo for new plant

cauliflower

flower

produces fruit and attracts pollinators

carrots

root

anchors plant and takes in water and minerals

tomatoes

fruit

holds and disperses seeds; protects embryo

spinach

leaf

makes food (site of food production)

celery

stem

provides support and carries water, minerals and food to all parts of the plant

Have students identify each item. In small groups, as food is passed to each group, have students classify each food as a root, stem, leaf, flower, fruit, or seed. Have groups record their placements on a chart or board visible to everyone. Through class discussion, clarify the part of the plant each food represents.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.3).

Reflecting: (SCI.II.1.E.1), (SCI.II.1.E.2).

Assessment Example

Students will create a salad made of plant parts. They will incorporate each plant part in the salad. They will identify the part and the function of each part through a written “menu,” a labeled diagram, or an oral presentation about the salad.

(Give students rubric before activity.)
