What is classification?
100
The basic unit of structure and function in living things.
What is a cell?

What is a cell wall?
100
A small, round cell structure containing chemicals that break down large food particles into smaller ones.
What is a lysosome
200
An organism that makes its own food.
What is an autotroph?
200
A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce.
What is a species?
200
Using a homemade compound microscope this English scientist and inventor coined the word "cells" while observing a thin slice of cork which to him looked like tiny rooms.
Who is Robert Hooke?
200
Rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions.
What are mitochondria?
200
A sac inside a cell that acts as a storage area.
What is a vacuole?
300
The maintenance of stable internal conditions.
What is homeostasis?
300
Swedish naturalist Carolus Linnaeus' system for naming organisms in which each organism is given a unique, two-part scientific name indicating its genus and species.
What is binomial nomenclature?
300
A microscope that uses more than one lens.
What is a compound microscope?
300
A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
What is endoplasmic reticulum?
300
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
What is a Golgi body?
400
Water, food, living space, and stable internal conditions.
What do living things need to survive?
400
Organisms with cells that contain nuclei that belong to one of four kingdoms: protists, fungi, plants, or animals.
What are eukaryotes?

This microscopes use a beam of electrons instead of light to produce a magnified image.
What is an electron microscope?
400
A small grain—like structure in the cytoplasm of a cell where proteins are made.
What is a ribosome?
400
The region between the cell membrane and the nucleus; in organisms without a nucleus, the region located inside the cell membrane.
What is cytoplasm?
500
Have a cellular organization, contain similar chemicals, use energy, respond to their surroundings, grow and develop, and reproduce.
What characteristics do all living things share?
500
An organism whose cells lack a nucleus and some other cell structures.
What is a prokaryote?
500
This states the following:
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
All cells are produced from other cells.
What is the cell theory?
500
A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.
What is a chloroplast?
500
A cell structure that controls which substances can enter or leave the cell.
