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 missing plant structures that correspond to the human structures listed in the chart, we need to understand the functions and structures of each.

1. Gas exchange:
In humans, gas exchange occurs in the lungs, where oxygen is taken in and carbon dioxide is released. In plants, gas exchange takes place in specialized structures called stomata. Stomata are small openings on the surface of leaves and stems that allow for the exchange of gases, including oxygen and carbon dioxide.

2. Circulation:
Humans have a system of blood vessels, including arteries, veins, and capillaries, for the circulation of blood. In plants, the function of circulation is performed by specialized tissues called xylem and phloem. Xylem transports water and dissolved minerals from the roots to the rest of the plant, while phloem transports sugars, amino acids, and hormones throughout the plant.

3. Water intake:
In humans, water intake occurs through the mouth, where it is ingested. In plants, water is absorbed from the soil through root structures. Roots have various adaptations, such as root hairs, that increase the surface area for water absorption.

4. Energy intake:
In humans, energy intake occurs through the mouth when food is ingested. Plants, on the other hand, use chloroplasts for energy intake. Chloroplasts are organelles found in plant cells that carry out photosynthesis, the process by which plants convert sunlight into energy (in the form of glucose) using water and carbon dioxide.

5. Internal support:
Humans have a skeleton made up of bones that provides internal support and shape to the body. Similarly, plants have a structural component called the stem that provides support to the plant and allows for the transport of water, nutrients, and sugars between the roots and leaves.

6. Energy Storage:
In humans, energy is stored in the form of fat cells, which serve as a reserve of stored energy. Plants, on the other hand, store energy in structures called vacuoles. Vacuoles are membrane-bound organelles found in plant cells that store water, ions, and other molecules, including sugars and starches.

7. Energy Conversion:
Humans have mitochondria, which are organelles responsible for cellular respiration and energy conversion, producing adenosine triphosphate (ATP). In plants, the process of energy conversion occurs in chloroplasts during photosynthesis. The leaves of plants contain chloroplasts, where the conversion of light energy into chemical energy (glucose) takes place.

So, filling in the missing plant structures:

1. Gas exchange: Stoma
2. Circulation: Xylem
3. Water intake: Roots
4. Energy intake: Chloroplasts
5. Internal support: Stem
6. Energy Storage: Vacuole
7. Energy Conversion: Leaves
