Key Ideas Flashcards
What are the key ideas in biology?
-Life processes depend on molecular structure and function.
-Cells form tissues, organs, and organ systems.
Organisms interact in populations, communities, and ecosystems.
-Organisms are interdependent and adapted to their environment.
-Life depends on photosynthesis, respiration, and chemical cycles.
-Characteristics are influenced by genes and environment.
-Evolution occurs through natural selection, creating biodiversity.
Key ideas provide a foundational understanding of biological principles and interactions.
How do molecules relate to life processes?
Molecules’ structures are designed for specific functions, enabling life processes.
The specific arrangement of atoms in molecules allows for their diverse roles in biological functions.
What role do cells play in living organisms?
Cells are the basic units of life, forming tissues, organs, and organ systems.
Understanding the structure and function of cells is crucial for studying all levels of biological organization.
How do tissues, organs, and organ systems work?
Tissues perform specific functions.
Organs are made of tissues working together.
Organ systems carry out life processes.
This hierarchical organization allows for complex functions and interactions within organisms.
How do organisms interact with their environment and humans?
Organisms form populations and ecosystems, interacting with each other and their environment. Humans influence these interactions.
The dynamics of these interactions are essential for understanding ecological balance and conservation.
What is photosynthesis and why is it important?
Photosynthesis is how plants and algae use sunlight to make organic compounds, producing oxygen and fixing carbon dioxide.
This process is fundamental to life on Earth, providing energy and oxygen for many organisms.
What is the role of organic compounds in respiration?
Organic compounds are used as fuels in cellular respiration to power essential chemical reactions.
This process is critical for energy production in living organisms.
How are chemicals cycled in ecosystems?
Chemicals continually cycle through ecosystems in processes like decomposition and nutrient recycling.
These cycles are vital for maintaining ecosystem health and productivity.
How does the genome and environment affect an organism?
An organism’s genome and its environment influence its characteristics and behaviors.
This interplay is central to understanding evolution and adaptation.
How does evolution occur?
Evolution happens through natural selection, leading to biodiversity and relatedness among species.
Natural selection is a key mechanism driving the evolution of species over time.
Fill in the blank: The basic units of life are called _______.
cells
Cells are the smallest unit that can carry out all life processes.
