Organisms and Interactions

The video tutorial explains the importance of plants in providing food, oxygen, and materials. It describes the basic requirements for plant growth: air, water, and sunlight. The tutorial includes an activity where students grow plants from seeds using a Ziploc bag or a plastic bottle. Students are instructed to observe and document the growth process over two to three weeks, analyzing the factors that contribute to plant growth.

What are some of the essential roles that plants play in our ecosystem?

• They do not contribute to the ecosystem.

• They are only used for decoration.

• They consume oxygen and produce carbon dioxide.

Which elements are crucial for the growth of plants?

• Air, water, and sunlight

• Soil, rocks, and sand

• Wind, fire, and earth

• Plastic, metal, and glass

What is the first step in setting up the plant growth activity using a Ziploc bag?

• Place seeds directly in the bag.

• Wet a paper towel and place it in the bag.

• Fill the bag with soil.

• Add fertilizer to the bag.

How often should you document your observations during the plant growth activity?

• Every two days

• Every day

• Only at the end of the experiment

• Once a week

What should you use to support the idea that plants need air, water, and sunlight for growth?

• Personal opinions

• Evidence from the activity

• Random guesses

• Unrelated experiments
