• Molecular Biology: study of the structure, function, and interactions of biological molecules such as DNA, proteins, and carbohydrates
• Cell Biology: study of the structure, function, and behavior of cells
• Evolutionary Biology: study of the processes that have shaped the diversity of life on Earth
• Marine Biology: study of organisms that live in the ocean
• Conservation Biology: study of the preservation and protection of threatened and endangered species and ecosystems

Biological Molecules

• Carbohydrates: provide energy for the body, examples include sugars and starches
• Proteins: perform a wide range of functions, including structural, enzymatic, and transport roles
• Lipids: provide energy and structure, examples include fats and oils
• Nucleic Acids: store and transmit genetic information, examples include DNA and RNA

Cell Structure and Function

• Cell Membrane: a semi-permeable membrane that surrounds the cell and regulates what enters and leaves
• Cytoplasm: a gel-like substance inside the cell membrane where metabolic processes take place
• Nucleus: the control center of the cell where DNA is stored
• Mitochondria: the powerhouses of the cell where energy is produced
• Ribosomes: small organelles where protein synthesis takes place
• Lysosomes: membrane-bound sacs that contain digestive enzymes and help break down and recycle cellular waste

Biological Processes

• Photosynthesis: the process by which plants and some other organisms convert light energy into chemical energy
• Respiration: the process by which cells generate energy from glucose
• Metabolism: the sum of all chemical reactions that occur within an organism
• Homeostasis: the ability of an organism to maintain a stable internal environment despite changes in the external environment
• Growth and Development: the process by which an organism grows and develops from a single cell to a mature individual

Cell Structure and Function

• The Cell Membrane controls the entry and exit of substances, maintaining the internal environment's stability.
• Cytoplasm is a gel-like medium where metabolic activities occur, facilitating biochemical reactions.
• The Nucleus serves as the cell's control center, housing DNA and overseeing cellular functions.
• Mitochondria are the energy-producing units of the cell, generating ATP through respiration.
• Ribosomes are responsible for protein synthesis, crucial for cellular function and growth.
• Lysosomes contain digestive enzymes, aiding in the breakdown and recycling of cellular waste materials.

Biological Processes

• Photosynthesis converts light energy into chemical energy, primarily in plants, vital for food production.
• Respiration generates energy from glucose, essential for cellular processes.
• Metabolism encompasses all chemical reactions in an organism, supporting life activities.
• Homeostasis maintains stable internal conditions despite external environmental changes, crucial for survival.
• Growth and Development tracks an organism's progression from a single cell to a fully mature entity, crucial for life cycles.
