= Introduction =

Plants are important to every species on earth. Plants take in carbon dioxide and produce oxygen. And we need oxygen to live. Plants are so important that scientists came up with a way to grow plants without soil. Fortunately plants have a special process called ** photosynthesis ** that helps keep them alive. Plants also have certain structures inside their cells that work to keep them alive.

toc = What Part(s) of a Plant Cell Cause Photosynthesis? =

Photosynthesis is when plants turn co2 and water into food and oxygen. First the ** chlorophylles ** absorb the energy from sunlight. Chlorophylles are little pigments inside chloroplasts that absorb the energy from sunlight. Then the **chloroplasts** use that energy to turn co2 and water into food and oxygen for the cell.

= What Parts Do Plant Cells Have That Animal Cells Don’t? =

The chloroplasts are one part. Which I talked about before. The **cell wall** is another part. The cell wall protects the cell and stops the cell from bursting when too much water enters the cell. The **central vacuole** is also a part. The central vacuole helps stop the problem of too much water entering the cell.

= What is Hydroponics? =


 * Hydroponics ** is when plants are grown in nutrients instead of soil. Hydroponics is used when the soil is to bad to grow plants. When hydroponics is used plants get the nutrients they need directly from water. There are two methods of hydroponics. One method is water culture. Plants are held with their roots in water which contains the nutrients the plant needs to survive. The plants’ roots absorb water and nutrients and air is pumped or mixed into the water regularly so the roots can absorb oxygen. Another method is aggregate culture. The plants’ roots are put into coarse sand, gravel, peat, perlite, or vermiculite. The water containing nutrients is added to the coarse sand, gravel, peat, perlite, or vermiculite. The plants’ roots absorb water and nutrients and anchor the plants.

= Conclusion =

Plants are important to life. Plants have photosynthesis to help keep them alive. They also have special structures to keep them alive. And we even grown crops without soil in areas that are not good for growing plants. Plant should not be ignored as “unimportant” because they are keeping us alive.
