What is photosynthesis?
Photosynthesis is the process by which plants make their food and energy.
100
Define deforestation
The removal of trees
100
What is an organelle? Give one example.
An organelle is like a cell's organ; they are inside cells and have various functions. Examples could be the mitochondria, nucleus, ER, Golgi body, etc.
200
A list of steps in the experiment is called:
the procedure
200
Is mold alive? How does it reproduce?
Yes; mold spores
200
What are the three ingredients for photosynthesis?
Sun Water Carbon dioxide
200
What gas do we have less of if we cut down trees?
Oxygen
200
What do the ER and Golgi bodies do?
Prepare and transport proteins
300
In an experiment, what is the purpose?
The purpose is the question you are trying to answer
300
What is an adaptation?
A characteristic of a living thing that helps it survive in a given environment
300
What two things does photosynthesis produce?
Oxygen Glucose
300
What are three effects of deforestation?
Less oxygen More air pollution Animals losing their habitats Animals becoming endangered
300
What are two cell parts that only plant cells have? Hint: One is involved in photosynthesis
Cell wall Chloroplast
400
Which axis is the x-axis? The y-axis?
The x-axis is horizontal (side to side). The y-axis is vertical (up and down)
400
What is homeostasis? Response to stimuli?
Homeostasis is internal regulation. Response to stimuli is reaction to the outside world.
400
Where in the plant cell does photosynthesis occur?
Chloroplasts
400
What are two possible causes of oil spills and two possible effects?
Causes: natural disaster, human error in preparing containers, crashes Effects: Birds' getting stuck in water, mammals losing ability to insulate against cold, beach ecosystems' being affected
400
In a line graph, which axis is typically labeled with the time?
x-axis
500
What is the independent variable? What is the dependent variable?
The independent variable is what YOU change. The dependent variable is the result, and changes based on the independent variable.
500
List five characteristics of life.
Made of cells Response to stimuli Homeostasis Exchange of gases Elimination of waste Nutrients for energy Reproduction and adaptation Growth
500
What gives plants their green color?
Chlorophyll Half points for chloroplasts, which holds chlorophyll
500
What are five ways you can help the environment?
Recycling Planting trees Carpooling, taking public transportation, riding bikes, etc. Not setting off fireworks near wildlife Not smoking Etc.
