À propos de ce fichier

This flashcard set is designed for secondary school students to build a strong foundation in biology vocabulary. It covers essential terms related to organisms, cells, and their structures, such as organelles like the mitochondrion and ribosome, as well as key biological processes like respiration and reproduction. The flashcards also explore different types of living things, including plants, animals, and bacteria, and delve into concepts like adaptation, evolution, and biotechnology. Ideal for students looking to expand their biological knowledge, this set helps in understanding the fundamental building blocks of life and their interactions within various environments.
