Document Summary
Most of the energy we use comes from burning fossil fuels- oil, natural gas, and coal. Through the decay of plants and algae living in swamps millions of years ago. Fossil fuels are nonrenewable, meaning they aren"t able to be used twice. Fossil fuels are also finite, meaning they are limited. Burning fossil fuels adds to the negative effect of global warming because it releases carbon dioxide. So, we resort to plants for energy, rather than burning fossil fuels. They capture sunlight through photosynthesis, converting different types of energy to grow and reproduce. The cell is surrounded by the cell membrane, which directs what goes in and out of the cell. Inside the cell membrane is the cytoplasm and nucleus, which holds the dna material. The cytoplasm holds many different organisms that has different functions. Plant cells have two differences when it comes to animal cells. Plant cells have a rigid cell wall that surrounds the cell membrane.
