The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.
• Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are "finger-like" projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.
• The brain is the control center of the body. One of these furrows, the medial longitudinal fissure, divides the brain into left and right hemispheres. Covering the brain is a protective layer of connective tissue known as the meninges.
• The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body.
Similar: They are made by proteins and glycoproteins like all the cells are. The also have DNA or RNA to reproduce and they also evolve to adapt.
Difference: They don't use the cell division phase and they are not alive.
All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.
Answer: photosynthesis
Explanation: leaves are a very important part of the plant. plants are autotrophic in nature. They can synthesize their own food. Leaves have green color pigment in it which is called chlorophyll. This chemical compound chlorophyll uses light energy from the sun and converts water and carbon dioxide into sugars. By this method, plants prepare their own food.
