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.
Function/ Human Structure/ Plant Structure
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 1. Fat cells 1. Vacuole
7. Energy Conversion 7. Mitochondria 7. Leaves
To fill in the plant structures that correspond to the human structures listed in the chart, we need to identify the plant structures that perform similar functions.
1. Gas exchange:
In humans, gas exchange occurs in the lungs. In plants, gas exchange occurs through tiny openings called stomata, which are primarily found on the surfaces of leaves and stems.
2. Circulation:
Humans have blood vessels for circulation. In plants, the equivalent structures are xylem and phloem. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars and nutrients to various parts of the plant.
3. Water intake:
Humans take in water through their mouth. Similarly, plants take in water from the soil through their roots. So, roots are the corresponding structure for this function.
4. Energy intake:
Humans take in energy through their mouth by consuming food. Plants, on the other hand, use chloroplasts present in their cells to convert sunlight into energy through photosynthesis. Therefore, chloroplasts are the corresponding plant structure for energy intake.
5. Internal support:
Humans have a skeleton that provides internal support. In plants, the stem serves a similar function by providing support and structure to the plant.
6. Energy storage:
In humans, fat cells store energy. For plants, vacuoles serve as storage structures. The plant vacuole can store water, nutrients, and even waste products.
7. Energy conversion:
Humans rely on mitochondria within their cells to convert energy stored in food molecules into usable energy for the body. In plants, energy conversion occurs in the chloroplasts during photosynthesis. Therefore, leaves, which contain chloroplasts, are the corresponding plant structure for energy conversion.
By matching the human structures with the plant structures based on their similar functions, we can complete the chart.
