Science Warm Up #1 (Week 17)

Naomi and Logan are working on a science project about plant growth. They want to know which process in plants depends on the intensity of visible light. Can you help them figure it out?

• photosynthesis

• blowing of wind

• evaporation of water

• formation of ozone layer

During a science class, McKenzie and Logan were discussing how algae in a pond get their energy. How do algae obtain the energy they use as food?

• They use photosynthesis to change light energy into food energy.

• They use cellular respiration to change oxygen into food energy.

• They are so small that they can absorb the energy they need from water.

• They are parasites that attach to fish to absorb the energy they need.

Kendall and Nola are learning about how plants make their own food. They discover that plants use energy from ______ to make their own food from water and carbon dioxide.

During a science class, Amina and Ryelle were discussing plant processes. Which of the following is true?

• Humans, goats, and cats release carbon dioxide during photosynthesis.

• Humans, goats, and cats take in carbon dioxide for respiration.

• Plants take in carbon dioxide for respiration.

• Plants take in carbon dioxide for photosynthesis.

Asheer and McKenzie are learning about how plants make their food. Which of the following is taken in from the atmosphere through leaves to make food for a plant?

• carbon dioxide

• glucose

• oxygen

• hydrogen

During a science class, Bradley and Amina learned that plants use energy from sunlight to make their own food from water and ______.

During a science class, Angel and Alyssa were discussing how plants function. Which statement is not an accurate description of plant activity?

• plants use sunlight, nutrients from the soil, water and oxygen to make the food they need

• sugars are moved from the leaves to the roots through the stem

• roots carry water and nutrients from the soil to the rest of the plant

• photosynthesis occurs in tiny structures called chloroplasts

During a science class, Alyssa and Naomi learned that plants use energy from sunlight to make their own food from water and carbon dioxide through a process called _______.

During a science class experiment, Chloe and Naomi placed a plant in sunlight to observe photosynthesis. Which gas is released during this process?

• nitrogen

• hydrogen

• carbon dioxide

• oxygen

Kendall planted a flowering plant in a flower pot. She used rich soil and watered it regularly. She then placed the plant into a sealed plastic bag and hid it in her closet for a week. She still watered the plant daily, but her plant did not survive. Kendall's plant did not survive because she did not provide ________, which are basic needs of the plant.
