Organisms and Interactions

The video tutorial explains the importance of plants in providing food, oxygen, and materials. It describes how plants grow from small organisms to large trees, requiring air, water, and sunlight. The tutorial includes an activity where students grow plants from seeds using a Ziploc bag or a plastic bottle, observing growth over two to three weeks. Students are encouraged to document their observations and analyze the factors that contribute to plant growth.

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

• They only produce oxygen.

Which elements are necessary for plant growth as mentioned in the introduction?

• Air, soil, and nutrients

• Water, nutrients, and sunlight

• Soil, water, and sunlight

• Air, water, and sunlight

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

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

• Fill the bag with soil.

• Place seeds directly in the bag.

• Add water to the bag.

How often should observations and drawings of the seeds be made during the activity?

• Only at the end of the experiment

• Every day

• Every two days

• Once a week

What should students use to support their answers about plant growth factors?

• Theoretical knowledge

• Textbook examples

• Evidence from the activity

• Their imagination
