World History Semester B Exam Review Cheat Sheet
- Characteristics of Life - Life feels like a dream team with eight superpowers: order, response to stimuli, reproduction, adaptation, growth, regulation, homeostasis, and energy processing. These traits help us tell living systems apart from rocks or stars. Mastering them lays the foundation for all biology topics. OpenStax Biology: Themes & Concepts
- Levels of Biological Organization - Biology is one giant set of nesting dolls, starting at atoms, moving through molecules, cells, tissues, organs, systems, organisms, populations, communities, ecosystems, all the way up to the biosphere. Recognizing each layer helps you see how small processes build massive effects. It's like seeing the forest and the trees at the same time. OpenStax Biology: Themes & Concepts
- Prokaryotic vs. Eukaryotic Cells - Prokaryotes rock a minimalistic design with free-floating DNA and no nucleus or fancy organelles, while eukaryotes bring a full cellular toolkit including a nucleus, mitochondria, and endoplasmic reticulum. Spotting their structural differences is key to unlocking everything from microbiology to human physiology. NursingHero: Prokaryotes vs. Eukaryotes
- Cell Organelle Structure & Function - Imagine the nucleus as headquarters, controlling gene secrets; mitochondria as power plants, fueling cell work; ribosomes as protein factories; the ER and Golgi as packing and shipping centers; and lysosomes as waste management. Each organelle plays a unique role in keeping cells running smoothly. NursingHero: Cell Organelles
- Membrane Transport Mechanisms - Diffusion and osmosis let molecules and water drift down concentration gradients like crowds moving naturally, while active transport uses protein pumps and ATP to escort substances against the flow. Understanding these processes explains how cells stay balanced, fueled, and ready to respond. NursingHero: Membrane Transport
- Mitosis & Meiosis - Mitosis is your body's construction crew, splitting one cell into two identical twins for growth and repair. Meiosis is the genetic remix master, creating four unique gametes with half the DNA - critical for sexual reproduction and diversity. Knowing these stages helps you track how life keeps rolling across generations. NursingHero: Mitosis & Meiosis
- Cell Communication Pathways - Cells send and receive chemical gossip using signaling molecules like hormones or neurotransmitters, binding to receptors like secret handshakes. Once they connect, pathways activate, altering cell behavior from growth to death. Decoding these conversations is vital for grasping health, disease, and development. NursingHero: Cell Signaling
- Stem Cell Properties - Stem cells are biology's ultimate shapeshifters: they can self-renew and differentiate into specialized cells. Their versatility makes them superheroes in regenerative medicine, offering promise for healing injuries or fighting disease. Understanding their properties bridges basic biology with cutting-edge therapies. NursingHero: Stem Cells
- Cell Differentiation & Specialization - Differentiation is cells claiming their job roles - like becoming muscle fibers, neurons, or blood cells - unlocking unique structures and functions. This specialization builds tissues and organs, transforming simple cell blobs into complex bodies. Mastering this concept clarifies how form meets function in multicellular life. NursingHero: Cell Differentiation
- Cell Aging & Apoptosis - Cellular aging, or senescence, is when cells hit their division limit and retire, sometimes stubbornly sticking around. Apoptosis is programmed self-destruction, a tidy demolition that removes damaged or surplus cells. These processes keep development on track, prevent cancer, and maintain tissue health.
