FLASHCARD QUESTION
Front
Which part of a plant is the star of the photosynthesis show?
Back
Leaves
Answer explanation
The leaves are the primary site of photosynthesis in plants, where they capture sunlight and convert it into energy. Thus, if a plant could sing, the leaves would be the star of the photosynthesis show.

FLASHCARD QUESTION
Front
What’s the “Enchanted” green pigment in plants that lets them soak up sunlight and turn it into energy?
Back
Chlorophyll
Answer explanation
The "Enchanted" green pigment in plants is chlorophyll. It absorbs sunlight, allowing plants to convert light energy into chemical energy through photosynthesis, which is essential for their growth and survival.

FLASHCARD QUESTION
Front
When plants are “Out of the Woods” and finish photosynthesis, which of these do they release into the air like a hit single?
Back
Oxygen
Answer explanation
During photosynthesis, plants convert carbon dioxide and water into glucose and oxygen. The oxygen produced is released into the air, making it the correct answer, as it is akin to a hit single in its importance to life.

FLASHCARD QUESTION
Front
Which of these lyrics best describes the process of photosynthesis, Taylor’s style?
Back
Plants use sunlight to make food from carbon dioxide and water.
Answer explanation
The correct choice, 'Plants use sunlight to make food from carbon dioxide and water,' accurately describes photosynthesis, where plants convert light energy into chemical energy, producing food and oxygen.

FLASHCARD QUESTION
Front
Why do plants “Shake It Off” and let go of oxygen during photosynthesis?
Back
Because oxygen is a waste product of making food
Answer explanation
Plants "Shake It Off" and release oxygen because it is a waste product of photosynthesis, the process they use to make food. This allows them to maintain balance and continue producing energy.

FLASHCARD QUESTION
Front
If a plant is left in the dark and can’t “Begin Again” with sunlight, what will most likely happen to its oxygen production?
Back
It will decrease
Answer explanation
In the dark, a plant cannot perform photosynthesis, which is essential for oxygen production. Without sunlight, its ability to produce oxygen will decrease significantly.

FLASHCARD QUESTION
Front
Why is photosynthesis a “Love Story” for animals?
Back
It produces oxygen that animals need to breathe.
Answer explanation
Photosynthesis is a "Love Story" for animals because it produces oxygen, which is essential for them to breathe. Without oxygen, animals cannot survive, making this process vital for their existence.

FLASHCARD QUESTION
Front
Which plant will produce more oxygen after a week: the one in sunlight or the one in a dark room?
Back
The plant in sunlight, because it can perform photosynthesis.
Answer explanation
The plant in sunlight can perform photosynthesis, using light energy to produce oxygen. In contrast, the plant in the dark room cannot photosynthesize and will not produce oxygen.

FLASHCARD QUESTION
Front
A scientist wants to prove that plants are “Ready For It” and can produce oxygen during photosynthesis. Which experiment would be a chart-topping hit?
Back
Place a plant in a sealed jar with water and measure the gas bubbles formed on the leaves in sunlight.
Answer explanation
The correct experiment involves placing a plant in a sealed jar with water and measuring gas bubbles, which indicates oxygen production during photosynthesis in sunlight. This directly tests the plant's ability to produce oxygen.
