Obtaining and Using Energy
100
An attempt to answer the experimental question; written as an "If..., then..." statement.
What is a hypothesis?
100
All living things are made of ____; these build tissue, which builds organs, which builds organ systems, which builds a mulitcellular organism
What are cells?
100
Smaller structures within a cell are called _____
What are organelles?
100
The shape of DNA
What is a double helix?
100
Plants and animals obtain energy to carry out the characteristics of life through this process
What is cellular respiration?
200
A step-by-step list of tasks to be completed during an experiment
What is the procedure?
200
There are two forms of this; single-celled organisms undergo one form; multicellular organisms undergo another form
What is reproduction?
200
Very rigid in shape; contains organelles that are not found in animal cells; one organelle gives it it's shape
What is a plant cell?
200
Adenine & Thymine; Guanine & Cytosine
What are nitrogen bases?
200
ATP (energy) results from the reaction of these two molecules
What are glucose and oxygen?
300
The part of the experiment that the experimenter changes because s/he wants control over this factor; there is only one in every experiment
What is the independent variable?
300
This is located in the nucleus of all cells; chromosomes package it
What is DNA?
300
Called the "command center"; contains all of the instructions of an organism
What is the nucleus?
300
The two components of the backbone
What are sugar and phosphate?
300
Glucose is created in this process
What is photosynthesis?
400
The part of the experiment that changes as a result of the independent variable; these are the observations you make during the experiment
What is the dependent variable?
400
Organisms (living things) _____ in order to be better suited to the environment and/or situation
What is adapt?
400
The organelle that allows photosynthesis to take place; contains chlorophyll; carbon dioxide and water must also enter
What is the chloroplast?
400
Either a long or short section of DNA; responsible for characteristics
What are genes?
400
All living things obtain energy from this
What is glucose?
500
A group within the experiment that is not exposed to the independent variable; it is used as a comparison group
What is the control group?
500
In order to carry out the characteristics of life, cells must use this, which is a product of cellular respiration
What is energy?
500
Animal and plant cells vary slightly in structure, but relate heavily in _____
What is function?
500
A gene is composed of a minimum of two of these; responsible for traits
What is an allele?
500
Diffusion and osmosis are examples of this; it refers to the in and out movement of materials within cells
What is cell transport?
