What will you learn in this lesson?

Plants make their own food through photosynthesis, and some have vessels for transport while others don't. In this lesson you learn the parts of a plant and their functions, and the difference between vascular and nonvascular plants.

  • Describes photosynthesis, its inputs, and its products
  • Identifies the function of xylem and phloem in a vascular plant
  • Compares vascular plants with nonvascular plants such as mosses
  • Explains the role of stomata and chlorophyll in a plant's leaf

💡 Tip: To tell xylem from phloem: xylem carries water and minerals up from the roots, and phloem carries the food made in the leaves to the rest of the plant.

Worked examples from the Plants lesson questions

What is the green substance in plant leaves that absorbs the energy of sunlight?
  • Chlorophyll
  • Sugar
  • Oxygen
  • Pollen
✓ Chlorophyll
Chlorophyll is a green substance found in chloroplasts, and it absorbs the light energy needed for photosynthesis.
Which tubes carry water and minerals from the roots to the rest of the plant?
  • Xylem
  • Phloem
  • Stomata
  • Petals
✓ Xylem
Xylem carries water and minerals up from the roots, while phloem carries food.

Which of the following plants is nonvascular?
  • Mosses
  • Ferns
  • Palm trees
  • Pine trees
✓ Mosses
Mosses have no tubes to carry water and food, while ferns, palm trees, and pine trees are vascular plants.
What are the products of photosynthesis?
  • Sugar and oxygen
  • Carbon dioxide and water
  • Oxygen and water
  • Sugar and carbon dioxide
✓ Sugar and oxygen
The plant uses water, carbon dioxide, and light energy to make sugar (food) and gives off oxygen.
Where does carbon dioxide gas enter a plant's leaf?
  • Through the stomata
  • Through the roots
  • Through the flowers
  • Through the phloem
✓ Through the stomata
Stomata are tiny openings in the leaf through which carbon dioxide enters and oxygen and water vapor leave.

FAQ about the Plants lesson

What are the products of photosynthesis?

The plant produces sugar as its food and releases oxygen gas into the air, using water, carbon dioxide, and the energy of sunlight absorbed by chlorophyll.

What is the difference between vascular and nonvascular plants?

Vascular plants have transport tubes (xylem and phloem) that let them grow tall, such as the palm tree. Nonvascular plants have no tubes, so they stay small and live in damp places, such as mosses.

How do I study the lesson Plants and test myself on it?

Start the lesson quiz on Study with Ghada: 10 questions from the Science Fifth Grade, Primary question bank. After each answer you'll see the right answer with an explanation, and any questions you miss move to “Review my mistakes” until you master them.

Are Study with Ghada quizzes free and aligned with the curriculum?

Yes, completely free. They're built on the Science - Grade 5 - Semester 1 lessons in the same order as the book, and every question is reviewed and approved by a teacher before students see it.
