📚 Sample Biology Terms
Mitochondria:
Membrane-bound organelles found in most eukaryotic cells that generate most of the cell's ATP through cellular respiration, often called the "powerhouse of the cell."
Homeostasis:
The ability of an organism or cell to maintain internal equilibrium by adjusting physiological processes despite changes in external conditions.
Photosynthesis:
The process by which green plants and certain other organisms convert light energy into chemical energy stored in glucose, using carbon dioxide and water while releasing oxygen.
DNA (Deoxyribonucleic Acid):
The hereditary material in humans and almost all other organisms, consisting of two strands forming a double helix carrying genetic instructions.
Ecosystem:
A biological community of interacting organisms and their physical environment, functioning as an ecological unit.
Natural Selection:
The differential survival and reproduction of individuals due to differences in phenotype, the key mechanism of evolution.
Enzyme:
A biological catalyst, typically a protein, that accelerates chemical reactions in living organisms without being consumed in the process.
