Match the following biological processes with their descriptions:

Diffusion = Movement of molecules from an area of high concentration to low concentration Osmosis = Movement of water molecules from an area of high water potential to low water potential Active transport = Movement of molecules against the concentration gradient requiring energy Photosynthesis = Process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll

Match the following parts of a cell with their functions:

Nucleus = Contains genetic material and controls cell activities Mitochondria = Site of aerobic respiration and ATP production Ribosomes = Site of protein synthesis Cell membrane = Controls the movement of substances into and out of the cell

Match the following biological terms with their definitions:

Heterozygous = Having two different alleles for a particular gene Meiosis = Cell division that produces gametes with half the chromosome number of the parent cell Mutation = A change in the DNA sequence that can lead to genetic variation Natural selection = The process where organisms better adapted to their environment tend to survive and produce more offspring

Match the following biological molecules with their functions:

Enzymes = Catalyzing chemical reactions Hormones = Regulating body functions Antibodies = Defending against pathogens ATP = Providing energy for cellular processes

Match the following ecological terms with their definitions:

Biodiversity = Variety of living organisms in an ecosystem Ecological niche = Role and position of a species within its environment Trophic level = Position of an organism in a food chain Biome = Large geographic area with similar climate and ecosystems

Match the following biological systems with their functions:

Respiratory system = Gas exchange and oxygen delivery Nervous system = Transmitting signals and coordinating body functions Endocrine system = Regulating body functions through hormone release Digestive system = Breaking down food and absorbing nutrients

Study Notes

Biological Processes

Matching of biological processes involves linking processes like photosynthesis, respiration, and mitosis with their respective descriptions.
Biological processes are essential functions that occur within living organisms, such as metabolism, growth, and reproduction.

Cellular Components

Cell parts like mitochondria, nucleus, and ribosomes are matched with their functions, such as energy production, genetic material storage, and protein synthesis.
Cellular components work together to maintain cellular homeostasis and perform various functions.

Biological Terms

Biological terms like genotype, phenotype, and habitat are matched with their definitions, such as an organism's genetic makeup, physical characteristics, and natural environment.
Understanding biological terms is crucial for clear communication and comprehension in biology.

Biological Molecules

Biological molecules like proteins, carbohydrates, and nucleic acids are matched with their functions, such as catalyzing reactions, providing energy, and storing genetic information.
Biological molecules are the building blocks of life and perform essential functions in living organisms.

Ecological Terms

Ecological terms like ecosystem, biodiversity, and adaptation are matched with their definitions, such as a community of living organisms, the variety of species in an ecosystem, and the ability of organisms to adjust to their environment.
Ecological terms are essential for understanding the relationships between living organisms and their environment.

Biological Systems

Biological systems like the circulatory, nervous, and immune systems are matched with their functions, such as transporting oxygen, transmitting information, and protecting against pathogens.
Biological systems work together to maintain overall health and function in living organisms.
