Prokaryotic cells are simple, single-celled organisms that do not have a defined nucleus or membrane-bound organelles. Eukaryotic cells, on the other hand, are more complex and have a defined nucleus and membrane-bound organelles.
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy. It involves the absorption of light by chlorophyll and the conversion of carbon dioxide and water into glucose and oxygen.
Natural selection is a process by which organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this can lead to changes in a population, resulting in evolution.
DNA, or deoxyribonucleic acid, contains the genetic information that determines an organism's traits and characteristics. It is passed down from parents to offspring and plays a crucial role in inheritance and genetic variation.
Biodiversity refers to the variety of living organisms in a given area. It is important because it helps maintain the balance of ecosystems and provides essential ecosystem services, such as air and water purification, nutrient cycling, and climate regulation.
