Plant Growth and Photosynthesis Concepts

Lily is preparing for a NASA engineering challenge to design a plant growth chamber. She learns from Dr. Goins about the importance of light for plants, the process of photosynthesis, and how to grow plants indoors. They discuss NASA's research on plant growth in space, focusing on light quality and quantity. Lily concludes by summarizing her learning and encouraging others to join NASA's challenges.

What is Lily preparing to design as part of NASA's challenge?

• A water filtration system

• A solar panel

• A plant growth chamber

• A space shuttle

What is the primary purpose of light for plants?

• To keep them warm

• To help them breathe

• To make them colorful

• To power photosynthesis

What is the role of chlorophyll in photosynthesis?

• It releases oxygen

• It traps sunlight

• It absorbs water

• It stores glucose

What are the two main colors of light that plants need to grow well?

• Red and blue

• White and black

• Green and yellow

• Orange and purple

What type of light bulbs are recommended for indoor plant growth?

• Neon bulbs

• Halogen bulbs

• Fluorescent bulbs

• Incandescent bulbs

Why is NASA interested in studying plant growth in space?

• To create new plant species

• To improve air quality in space

• To provide food for astronauts

• To decorate spacecraft

What happens to plants when they are grown under red and blue light?

• They become transparent

• They stop growing

• They appear black

• They turn green

What is a potential challenge of growing plants in space?

• Reduced gravity

• Lack of soil

• Limited water supply

• Excessive sunlight

What are tropisms in plants?

• Reactions to sound

• Movements towards light or water

• Changes in leaf color

• Growth in the absence of light

What do plants produce during photosynthesis?

• Carbon dioxide and water

• Oxygen and glucose

• Nitrogen and minerals

• Chlorophyll and sunlight
