Question

inside the leaf cells are special structures called chloroplasts where photosynthesis takes place. chloroplasts contain a green substance called chlorophyll, which gives plants their green color. chlorophyll is very important because it captures the suns energy and starts the whole process of photosynthesis. when sunlight hits the chlorophyll, it absorbs the light energy and uses it to change carbon dioxide and water into sugar and oxygen. this process is like a solar panel that turns sunlight into usable energy. thanks to photosynthesis, plants can make their own food and provide oxygen for other living things on earth.

1. photosynthesis happens in the ______________ of plant cells.

1. plants need ____________, ____________, and sunlight to make food during photosynthesis.

1. the gas released during photosynthesis is ______________.

Explanation:

Fill - in - the - blanks

1. Explanation for question 1:

• Step 1: From the passage, it says "Inside the leaf cells are special structures called chloroplasts where photosynthesis takes place."
• So the answer is chloroplasts.

1. Explanation for question 2:

• Step 1: The passage states "it absorbs the light energy and uses it to change carbon dioxide and water into sugar and oxygen." So plants need carbon dioxide and water (along with sunlight) to make food during photosynthesis.
• So the answers are carbon dioxide and water.

1. Explanation for question 3:

• Step 1: From the sentence "it absorbs the light energy and uses it to change carbon dioxide and water into sugar and oxygen", we can see that the gas released during photosynthesis is oxygen.
• So the answer is oxygen.

Short responses

1. Brief Explanations:

• From the passage, chlorophyll in chloroplasts captures the sun's energy, and this energy starts the whole process of photosynthesis. So plants need sunlight because the chlorophyll in their chloroplasts needs to capture the sun's energy to start the process of photosynthesis, which is used to convert carbon dioxide and water into sugar and oxygen.
• Answer: Plants need sunlight because the chlorophyll in their chloroplasts captures the sun's energy to start the process of photosynthesis, which is used to convert carbon dioxide and water into sugar and oxygen.

1. Brief Explanations:

• From the passage "it absorbs the light energy and uses it to change carbon dioxide and water into sugar and oxygen", plants take in carbon dioxide during photosynthesis and release oxygen.
• Answer: Plants take in carbon dioxide during photosynthesis and release oxygen.

1. Brief Explanations:

• The passage says "Thanks to photosynthesis, plants can make their own food and provide oxygen for other living things on Earth." Animals and humans need oxygen to breathe, and they also depend on the food (either directly from plants or indirectly from animals that eat plants) that plants produce through photosynthesis.
• Answer: Photosynthesis is important for animals and humans because plants produce oxygen (which animals and humans need to breathe) and make food (which forms the basis of the food chain for animals and humans, either directly or indirectly).
