Cells
smallest unit of living organisms
What is a cell
the study of life
What is biology
Organisms that make their own food
What are autotrophs?
the stage of growth and development in the cell cycle
What is the interphase
The two main energy molecules found in a cell
What are ATP and ADP
unicellular organisms, such as bacteria that lack internal membrane-bound organelles and a nucleus
What is a prokaryote
used by scientists to answer questions and solve problems
What is the scientific method
A sequence of who eats who to gain energy
What is a food chain?
net, random movement of particles from a higher concentration to an area of lower concentration; eventually resulting in an even distribution
What is simple diffusion
chemical reactions that do not require the presence of oxygen
What is anaerobic respiration
Produces proteins, can be attached the ER or free floating
What is the job of a ribosome?
an explanation for a question or a problem that can be formally tested
What is a hypothesis
Evaporation - condensation - precipitation
What is the water cycle?
the continuous sequence of growth and division by the cell; includes interphase, mitosis and cytokinesis
What is the cell cycle
the anaerobic reaction of cellular respiration; occurs in the cytoplasm of the cell
What is glycolysis
a selectively permeable structure of a cell; responsible for homeostasis of the cell
What is the plasma membrane
regulation of an organism's internal environment to maintain conditions suitable for its survival
What is homeostasis
A relationship among organisms where both benefit from each other
What is mutualism?
period of nuclear division in which two daughter cells are formed, each containing a complete set of chromosomes
What is mitosis
process by which autotrophs, such as algae and plants, trap light energy with chlorophyll and use this energy to convert carbon dioxide and water into glucose
What is photosynthesis
the power house of the cell; making ATP from glucose with oxygen
What is the mitochondria
the part of an experiment that the scientist observes or measures; any changes in it depend on changes made to condition tested
What is the independent variable
total weight of all living matter in a given area
What is biomass
passive transport of materials across a plasma membrane by transport proteins embedded in the plasma membrane.
What is facilitated diffusion
Includes glycolysis, citric acid cycle and electron chain transport
What is cellular respiration
