Biology 1 Exam Review
This set of flashcards is a review of the key vocabulary on the Biology 1 semester exam.
The smallest unit in living things that can still be considered alive. The basic unit of organization in living things.
A group of similar cells that perform a specific function.
A group of similar tissues that perform a particulat function.
Groups of organs that work together to perform specific functions.
Process by which organisms maintain an internal balance.
Process that helps living things respond to outside stimuli.
Chemical reactions that living things use to process materials.
Interpretation pased on prior knowledge and observation.
Smaller units that join together to make polymers.
Larger compound formed by joining monomers together.
Organic compound that serves as a building block for living things, speeds up reactions as a catalyst.
Organic compound that stores energy, helps form the cell membrane, provides insulation and protection.
Organic compound that is the main source of energy for living things.
Organic compound that stores and transmits your genetic information (heredity)
Building blocks or monomers for proteins.
Building blocks or monomers for nucleic acids.
Example of a monomer for carbohydrates. (it's a building block for polysaccharides)
Proteins that speed up the rate of chemical reactions.
This process assembles (makes) monomers into polymers.
The process that disassembles (breaks) polymers into monomers.
This organelle controls most of the cell's functions, stores DNA, and contains the instructions for making proteins.
This cell organelle makes proteins.
This organelle converts food energy into ATP, carbon dioxide and water.
This organelle stores water and other nutrients and is much larger in a plant cell than in an animal cell.
This organelle converts the energy from the sun into oxygen and sugars. It is also only found in plant cells.
The flexible boundary of plant and animal cells that allows materials in and out of the cell.
The rigid outer boundary of plant cells.
The movement of materials across a membrane that requires extra energy.
Movement of materials through the cell membrane from a region of high concentration to a region of low concentration.
Diffusion of water across the cell membrane.
Different cells in an organisms have different functions or jobs.
An educated guess that can be tested and is based on prior knowledge.
Biomolecule that stores energy for living things. Adenosine Triphosphate.
The process that uses sunlight to convert water and carbon dioxide into oxygen and glucose.
The process that converts Oxygen and Glucose into Carbon Dioxide, Water and ATP.
The pigment that absorbs the sun's energy in plants.
Uses oxygen as a part of cellular respiration. Releases the greatest amount of energy.
Cells which have a nucleus, are larger, more complex and contain membrane bound organelles.
Cells which have no nucleus, are smaller, less complex and have no membrane bound organelles.
Cellular Division which produces two identical daughter cells.
Cellular division which produces four different daughter cells.
Two sets of matching homologous chromosomes.
Only one copy of each chromosome.
Sex Cells. Example: Sperm and Egg Cells.
Process during Meiosis which helps to increase the genetic variability of daughter cells.
A picture which represents all of the chromosomes present inside nucleus of a cell.
Sex chromosomes of a female.
Sex chromosomes of a male.
Matching chromosomes that contain information for the same traits. One comes from the mother and one from the father.
