Life science is the branch of science that deals with living things. Studying the life processes of people, animals, and plants and any living organism falls under life sciences.
Several fields of science that study living organisms can be categorized under life sciences. These are biology, zoology, botany, virology, microbiology, entomology, taxonomy, physiology, and many others.
Forty percent of the GED test focuses on life science. You may be asked questions about human body and health, the relationship between life functions and energy intake, ecosystems, the structure and function of life, molecular basis of heredity, and evolution.
When studying life science, take note of the difficult terms that you are not familiar with. Many life science terms are not something that you encounter every day, like mitochondria, chromosome, endocytosis, or homeostasis. Find each term’s definition and origins. The word’s origins make it easy for you to remember and understand what the word actually means.
For example, you encounter the word carnivore and you’re not sure what that means. Look it up and check the word’s origins. It comes from the Latin word “carnivorous,” which combines the words “carō” and “vorāre,” which means “flesh” and “to consume” respectively. It is now easier to remember that carnivores mean flesh-eating animals.
When studying life processes and relationships, you can use drawings or maps to help you understand and remember the concepts behind them with ease.
