The basic unit of structure and function in all living things.
What is a cell?
100
The source of energy needed for photosynthesis to occur.
What is sunlight or light?
100
The process of grouping things based on their similarities.
What is classification?
100
The production of offspring that are similar to the parents.
What is reproduction?
100
Organisms, such as plants, that make their own food.
What are autotrophs?
200
This structure releases the chemical instructions that direct all the cell's activities.
What is the nucleus?
200
Large green structures floating in the cytoplasm where photosynthesis occurs.
What are chloroplasts?
200
The scientific study of how living things are classified.
What is taxonomy?
200
The terms meaning an organism consisting on one cell and an organism consisting of many cells.
What are unicellular and multicellular?
200
An organism, whose cells lack a nucleus and and other cell structures.
What is a prokaryote?
300
A tiny cell structure, such as the vacuole, that carries out a specific function within a cell.
What is an organelle?
300
A green pigment found in the chloroplasts of plant cells, that absorbs light energy from the sun for use in photosynthesis.
What is chlorophyll?
300
The main reason that bacteria are placed into their own kingdoms of Archaebacteria and Eubacteria.
What is because they lack a nucleus?
300
This process, the opposite of photosynthesis, occurs in the mitochondria and releases energy that an organism needs to survive.
What is respiration?
300
An organism, such as animal, that cannot make its own food and must take in food.
What is a heterotroph?
400
Kidney-bean shaped structures that produce the energy needed to carry out the cell's functions.
What are mitochondria?
400
The three raw materials required before photosynthesis can occur.
What are carbon dioxide, water and light?
400
Beside the two kingdoms of bacteria, Archaebacteria and Eubacteria, the other four kingdoms of life on Earth.
What are Protists, Fungi, Plants, and Animals?
400
A change in an organism's surroundings, such as a loud noise, that causes a response.
What is a stimulus?
400
An organism, such as a honey bee, whose cells contain a nucleus and many other cell structures.
What is a eukaryote?
500
The passageways that carry proteins and other materials from one part of the cell to another.
What is endoplasmic reticulum or ER?
500
The two product created by the process of photosynthesis.
What are glucose (sugar) and oxygen?
500
List from largest to smallest, the seven levels of classification for all living things.
What are kingdom, phylum, class, order, family, genus and species?
500
This theory, found to be false, suggested that living things arise from nonliving matter. An example of this theory would be mice come to life from hay.
What is spontaneous generation?
500
Binomial nomenclature means giving every creature a scientific name, consisting of a __ and a __.
