Characteristics of Living Things , Cycles , DNA , PhotoS and Cellular Respiration Flashcards
What is the smallest unit of all life? (The building blocks of life)
Cells
What process is used by organisms to get and use energy in order to carry out life functions this
Metabolism
When organisms maintain a constant internal environment this is called?
Homeostasis (Everyone wants a nice safe, stable home)
What is the term that means passing traits on to offspring?
Heredity
What is the term meaning that populations of organisms change gradually over time?
Evolution
A group of cells that carry out a similar function
Tissue
A group of tissues that carry out a specialized function
Organ
The smallest unit of life
Cell
A group of organs that work together to perform body functions
Organ System (Respiratory, Circulatory, skeletal…)
A single living thing
Organism
A group of organisms of the same species
Population
A group of different species that live in the same area and interact with each other
Community
A community of organisms and their non-living environment
Ecosystem
All of our world and its atmosphere that support life
Biosphere/Earth
What are the different parts of the water cycle?
Precipitation/Evaporation/Condensation/Transpiration/Runoff and Groundwater
The process by which plants release water vapor from their leaves into the atmosphere
Transpiration
When water percolates through the soil and enters an aquifer, what does it make?
Groundwater
What are the 2 cellular processes we call “opposite processes”?
Photosynthesis and Cellular Respiration
What are the 3 inputs to Photosynthesis?
Sunlight, CO2 and H2O
What are the 2 outputs of photosynthesis?
Glucose and O2(Oxygen)
Organisms that can make their own food are called?
Autotrophs (Self/feeders)
Organisms that cannot make their own food are called?
Heterotrophs (Other/feeders)
In what organelle does does photosynthesis take place
Chloroplasts
In what organelle does cellular respiration take place?
Mitochondria
What are the inputs to cellular respiration?
Glucose and Oxygen
What are the outputs from cellular respiration?
ATP + H2O + CO2
The nitrogen cycle is a complicated process. What is its’ main purpose?
To “fix” nitrogen from the air into the soil so organisms can get access to it.
The nucleic acid that is found inside the nucleus and that carries instructions for all our traits
DNA (Deoxyribonucleic acid)
What nitrogen bas bonds with Adenine
Thymine
What nitrogen base bonds with cytosine?
Guanine
Who discovered the shape of the DNA molecule?
Watson and Crick
Who took X-Rays of the DNA molecule to help us determine its structure?
Rosalind Franklin
What does replication mean?
Making an identical copy
Genetic Engineering creates a certain kind of organism. What is the term?
GMO - Genetically Modified Organism
What GMO did we study (Hint - It was created in Hawaii)
GMO Papaya
How many parts does the cell theory have?
3
All living things are composed of one or more cells
A cell is the basic unit of structure and function
All cells come from pre-existing cells
What are macromolecules?
Fats, Lipids, Carbohydrates, Proteins and Nucleic Acids
