=Introduction=

toc The plant cell absorbs light from the sun to make food, just like a solar panel. This process is known as photosynthesis. Then the plant cell will convert it to food by using resources surrounding it, but how will it do that? Plant cells also protect itself from harmful things such as animals or harmful diseases. The plant cell acts like it has its own security guard. You might not think that tiny cell could do a lot, therefore you are about to find out.

=In What Ways Do Plant Cells Function?=

Plant cells function in many ways, however it is mostly from the sunlight. For example a plant cells can produce oxygen and nutrients which is all a part of photosynthesis. Photosynthesis is when mostly all living things directly or indirectly absorb energy from the sunlight to help make food. Photosynthesis produces sugar ( food for the plant cell) by using the sunlight, water and carbon dioxide. Oxygen is also made, however it is a waste material for plants. First, the sunlight provides energy for the plant cell, just like a solar panel that you can find on the top of a majority of houses. Then, the energy that the sun provides helps the plant cell create food.According from the textbook, the light combines with carbon dioxide (CO2) and water (H2O) to create food. It mostly creates sugar which is a way of giving a plant cell a lot of energy, just like when humans eat sugar. The carbon dioxide comes from the air and the water comes from the moisture in the soil.Then the food will give the plant cell energy which helps it function (Textbook). This is why photosynthesis is very important in a plant cell. Also the chloroplast gets it green pigment from chemical color compound from chlorophyll. You can find the chloroplast inside a plant cell.

=What Are The Structures Of A Plant Cell?=

Plant cells have many ways of structure. They have structures that are specialized for photosynthesis. However, they can relate to animal cells by how they make food, also known as photosynthesis. Both animal and plant cells make food, but animal cells do not have photosynthesis meaning they do not combine co2 and H2O to make sugar which is energy for the plant cell. Therefore, animal cells just have to digest food in order to have energy. This is because animal cells do not have a cell wall, chloroplast and a vacuoles. According to the textbook, the cell wall protects the plant cell from harmful things entering and the vacuoles is a membrane-bound organelle. Also plant cells and animal cells are both eukaryotic cells. Eukaryotic cells are organism cells that contain a cytoplasm with specialized organelles, and a membrane-bound nucleus.



=How Do Plant Cells Defend Themselves Against Diseases And Other Harmful Things?=

Plant cells act like a window screen or a security guard when they are trying to protect themselves from harmful things. Say you work in a corporate and there is a security guard, the security guard will let in the people that work there but will not let in random people. A plant cell not only defends itself from diseases but it will also defend itself against pathogens, bacteria and more (Dictionary.com). The cell wall acts like a window screen, in will let in nutrients, but not harmful objects. Plant cells might also have physical functions on the outside of their body such as thorns that you can find on a rose bush or other plants. This function has the job to keep away animals trying to eat the plant. However, another example is a venus fly trap. A venus flytrap is a plant that captures bugs and other objects or living things trying to harm it. It is also spiky and sticky.

=Conclusion=

In conclusion, all of the solar panels and security guards come in handy to a plant cell. Plant cells have many jobs, functions and structures that are very important. For example when the plant cell is creating food with the help of the energy from the sun. This is why the solar panels are important to provide energy for the plant cell. Another example is when the plant cell is defending itself from harmful disease and objects it needs its own security guard to defend the harmful things. This is why photosynthesis, the cell wall, the chloroplast and more are important to a plant cell daily. You might not think such a tiny cell the size of 10-100 micrometers could do so much, but it really can.
