All living things must carry out certain functions and possess certain structures to survive, grow, and reproduce. The following chart illustrates how humans possess certain structures to carry out these critical functions. Fill in the plant structures that correspond to the human structures listed in the chart.

To fill in the plant structures that correspond to the human structures listed in the chart, you need to understand the functions and structures of both plants and humans. Here's how you can get the answer:
1. Gas exchange:
- Humans: Lungs are responsible for gas exchange in humans.
- Plants: Plants perform gas exchange through small openings called stomata on the surface of their leaves.
2. Circulation:
- Humans: Blood vessels, such as arteries and veins, are responsible for circulating blood through the human body.
- Plants: Plants have a system called xylem, which transports water and nutrients from the roots to other parts of the plant.
3. Water intake:
- Humans: The mouth is the structure through which humans take in water.
- Plants: Plants absorb water primarily through their roots, which serve as the structure for water intake.
4. Energy intake:
- Humans: The mouth is also responsible for the intake of energy-rich substances like food.
- Plants: Plants produce energy through photosynthesis, which occurs primarily in their leaves, particularly in the chloroplasts.
5. Internal support:
- Humans: The skeleton provides internal support and structure for the human body.
- Plants: Plants have a supportive structure called the stem, which helps them stand upright and provide support.
6. Energy Storage:
- Humans: Fat cells in the human body store energy.
- Plants: Plants store energy in special structures called vacuoles, which can store various materials, including carbohydrates.
7. Energy Conversion:
- Humans: Mitochondria are the structures responsible for converting stored energy into usable forms in human cells.
- Plants: Plants perform the conversion of energy through photosynthesis, primarily occurring in their leaves.
By understanding the functions and corresponding structures in both humans and plants, you can fill in the plant structures that correspond to the human structures listed in the chart as follows:
1. Gas exchange: 1. lungs -> 1. Stoma
2. Circulation: 2. Blood vessels -> 2. Xylem
3. Water intake: 3. mouth -> 3. Roots
4. Energy intake: 4. mouth -> 4. Chloroplasts
5. Internal support: 5. skeleton -> 5. Stem
6. Energy Storage: 6. Fat cells -> 6. Vacuole
7. Energy Conversion: 7. Mitochondria -> 7. Leaves
