Solution:
#### 1.
Photosynthesis
-
Definition of Photosynthesis:
- A process by which plants convert sunlight, water, and carbon dioxide into food energy (sugar), oxygen, and water.
-
Answer: Photosynthesis
-
Cellular Component for Photosynthesis:
- An elongated cell organelle containing chlorophyll where photosynthesis takes place.
-
Answer: Chloroplast
-
Molecule that Uses Light Energy:
- A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen.
-
Answer: Chlorophyll
-
Photosynthesis Equation:
- The equation for photosynthesis is:
\[
6\text{H}_2\text{O} + 6\text{CO}_2 + \text{light} \rightarrow \text{O}_2 + \text{C}_6\text{H}_{12}\text{O}_6
\]
-
Answer: Fill in the blanks as follows:
\[
6\text{H}_2\text{O} + 6\text{CO}_2 + \text{light} \rightarrow 6\text{O}_2 + \text{C}_6\text{H}_{12}\text{O}_6
\]
-
Absorption of Sunlight:
- The
chlorophyll absorbs the
sunlight. Chlorophyll then uses sunlight to change water, carbon dioxide, and nutrients from the soil. The chlorophyll processes the ingredients to make
glucose (plant food) and
oxygen.
-
Answers:
- First blank:
chlorophyll
- Second blank:
sunlight
- Third blank:
glucose
- Fourth blank:
oxygen
#### 2.
Animals and Plants Interaction:
-
What Animals Provide to Plants:
- Animals make the
carbon dioxide that plants need, and plants make the
oxygen that animals need.
-
Answers:
- First blank:
carbon dioxide
- Second blank:
oxygen
#### 3.
Respiration
-
Definition of Respiration:
- The process by which the chemical energy of "food" molecules is released and changed into ATP.
-
Answer: Respiration
-
Cellular Component for Respiration:
- Rod-shaped organelles with a double membrane which converts the energy stored in glucose into ATP for the cell.
-
Answer: Mitochondria
---
Final Answer:
\[
\boxed{
\begin{aligned}
&\text{1. Photosynthesis} \\
&\text{2. Chloroplast} \\
&\text{3. Chlorophyll} \\
&\text{4. } 6\text{H}_2\text{O} + 6\text{CO}_2 + \text{light} \rightarrow 6\text{O}_2 + \text{C}_6\text{H}_{12}\text{O}_6 \\
&\text{5. Chlorophyll, sunlight, glucose, oxygen} \\
&\text{6. Carbon dioxide, oxygen} \\
&\text{7. Respiration} \\
&\text{8. Mitochondria}
\end{aligned}
}
