About 10 minutes · 3 reading + 7 practice and checks
Time includes reading, practice, and questions. Extra videos or further study are optional.
See this course’s project requirements

A safe paper garden trial with plant requirements, container spacing, watering observations, a simple comparison and a revised growing plan.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Match fictional variety requirements to supplied sites.
  • Draw and explain a typical flowering plant’s parts.
  • Lay out container centers with spacing and margins.
  • Design a one-factor replicated paper comparison.
  • Calculate growth and interpret moisture observations without diagnosis.
  • Revise the plan from changed light evidence and retain trial limits.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Method: applies the course-specific rules to the supplied cases with visible intermediate work.
  • Accuracy: results agree with the stated facts, units, boundaries and independent checks.
  • Reasoning: explains why the result follows and identifies a limitation or unresolved question.
  • Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life

Original diagram described in words: part A is a branching structure below the potting surface; B is the broad green leaf surface exposed to light; C is the upright stalk joining roots and leaves; D is the flower at the shoot tip. The learner sketches this fictional plant from the description.

The idea

For a typical flowering vascular plant, roots anchor and take up water and minerals; stems support and connect transport pathways; leaves commonly capture light for photosynthesis; flowers are reproductive structures. Photosynthesis produces sugars using light energy, water and carbon dioxide; soil is not simply the plant’s complete food supply. These roles help interpret growing requirements without diagnosing plant disease.

Connect plant parts with their functions — worked practice

For a typical flowering vascular plant, roots anchor and take up water and minerals; stems support and connect transport pathways; leaves commonly capture light for photosynthesis; flowers are reproductive structures. Photosynthesis produces sugars using light energy, water and carbon dioxide; soil is not simply the plant’s complete food supply. These roles help interpret growing requirements without diagnosing plant disease.

Original diagram described in words: part A is a branching structure below the potting surface; B is the broad green leaf surface exposed to light; C is the upright stalk joining roots and leaves; D is the flower at the shoot tip. The learner sketches this fictional plant from the description.

  1. 1. 1. Label

    Name A, B, C and D.

    You should see: A roots; B leaves; C stem; D flower.

  2. 2. 2. Link

    Add the primary stated function beside each part.

    You should see: Uptake/anchoring; light capture; support/transport; reproduction.

  3. 3. 3. Trace

    Draw water’s simplified root-to-shoot route.

    You should see: Water uptake at roots, then transport through the stem toward leaves.

  4. 4. 4. Correct

    Repair “plants get all their sugar directly from soil.”

    You should see: Photosynthesis makes sugars using light energy and supplied water/carbon dioxide inputs.

Now change one thing

Original changed diagram: label A now points to a broad green blade exposed to light; label B points to branching structures below the potting surface. Enter roots or leaves for the changed label A.

Your work

What to finish

An original labeled plant sketch with four functions and a water route.

Common mistake

Watch for this

Light energy helps plants form sugars through photosynthesis. The other inputs and conditions remain necessary rather than being replaced by light.

How can I tell I understand it?

Identify a changed function without treating root uptake as the entire food-production process.
