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.

2. Circulation 2. Blood vessels 2.Xylem

7. Energy Conversion 7. Mitochondria 7. Leaves

To fill in the chart with the corresponding plant structures, we can compare the functions and structures of humans and plants.

1. Gas exchange:
In humans, gas exchange occurs in the lungs. Similarly, in plants, gas exchange occurs through small openings called stomata present on the surface of leaves.

2. Circulation:
Humans have blood vessels that help circulate blood throughout the body. In plants, the equivalent structure is xylem, which transports water and nutrients from the roots to other parts of the plant.

3. Water intake:
In humans, water intake occurs through the mouth. In plants, water uptake primarily happens through the roots. Roots absorb water from the soil.

4. Energy intake:
In humans, the mouth is responsible for taking in food, which provides energy. In plants, chloroplasts in the leaves capture sunlight and convert it into energy through photosynthesis.

5. Internal support:
Humans have a skeleton that provides internal support. Similarly, plants have stems that give structural support to the plant, keeping it upright and allowing the transport of nutrients.

6. Energy Storage:
Humans store energy in specialized cells called fat cells. In plants, energy storage occurs in the vacuoles, which are membrane-bound structures present in the plant cells.

7. Energy Conversion:
In humans, energy conversion takes place in the mitochondria, which are the powerhouses of the cells. In plants, energy conversion occurs in the chloroplasts present in the leaves through photosynthesis. Leaves capture sunlight and convert it into chemical energy.

Now that we have filled in the chart, it's important to note that plants and humans have different structures and mechanisms to perform similar functions. It's this diversity in adaptations that allows different organisms to survive and thrive in their respective environments.
