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 corresponding plant structures for the human structures listed in the chart, we can examine the functions and find the plant structures that perform similar functions.
1. Gas exchange:
In humans, gas exchange occurs in the lungs. Plants, on the other hand, have small openings called stomata on the surface of their leaves that allow for the exchange of gases. So, the corresponding plant structure for gas exchange is the stomata.
2. Circulation:
Humans have blood vessels that help circulate blood throughout the body. In plants, the xylem tissue is responsible for transporting water and nutrients from the roots to the rest of the plant. Therefore, the corresponding plant structure for circulation is the xylem.
3. Water intake:
Humans take in water through their mouth. In plants, the roots are responsible for absorbing water and nutrients from the soil. Thus, the corresponding plant structure for water intake is the roots.
4. Energy intake:
Both humans and plants utilize the mouth for energy intake. Humans consume food through their mouth, while plants use their mouths (the stomata on the leaves) to take in carbon dioxide, which is essential for photosynthesis. Plants use chloroplasts found in their leaves to convert light energy into chemical energy through photosynthesis. Therefore, the corresponding plant structure for energy intake is the chloroplasts.
5. Internal support:
Humans have a skeletal system that provides internal support and structure. In plants, the stem serves as the main support structure, holding the leaves, flowers, and fruits. So, the corresponding plant structure for internal support is the stem.
6. Energy storage:
Humans store excess energy in fat cells. In plants, excess energy can be stored in specialized organelles called vacuoles. The vacuole is responsible for cellular storage, including water, nutrients, and energy reserves. Hence, the corresponding plant structure for energy storage is the vacuole.
7. Energy conversion:
Humans have mitochondria, which are the powerhouses of the cell and responsible for energy conversion. Plants carry out energy conversion through the process of photosynthesis, which occurs primarily in the chloroplasts found in the leaves. Therefore, the corresponding plant structure for energy conversion is the leaves.
