Chapter 4 Test

Coiled up chains of DNA that carry instructions on how to make proteins Chromosomes
Structure found in plant cells that uses light energy, water and carbon dioxide to make glucose; photosynthesis happens here Chloroplast
Structurs inside cytoplasm that have their own specific job or function Organelle
Watery fluid inside the cell that organelles are suspended in Cytoplasm
Place where proteins are built; free floating or attached to ER Ribosomes
Control center for the cell; contains genetic information (DNA) Nucleus
A cell that has a nucleus and other membrane bound organelles Eukaryotic
Provides shape, protection and support for plan cells; made of cullulose Cell Wall
Breaks down sugar to make energy (ATP); power house of the cell Mitochondria
Responsible for digestion in the cell; destroys worn-out organelles, gets rid of wastes and protects cell from harmful particles Lysosome
Flexible cover around the cell that controls movement of materials into and out of the cell; separates cell from outside environment Cell Membrane
Makes and modifies proteins and lipids; part of cell's delivery system; helps break down materials that can harm the cell Endoplasmic Reticulum
Small sac that surrounds material to be movewd in or out of the cell Vesicle
Simple cells with no recognizable organelles (no nucleus) Prokaryotic
Modifies, sorts, and ships molecules that are made in the ER; post office of cell Golgi Complex
Surrounds the nucleus; substances pass in and out through pores Nuclear Membrane
Type of vesicle found in plant cells; can store water, food, and waste products; soome have digestive enzymes Vacuole
Found in animal cells; form spindle fibers to separate chromosomes during cel division (mitiosis) Centriole
What are the 3 parts of the cell theory? 1. All organisms are made up of one or more cells 2. The cell is the basic unit for all living things 3. All cells come from existing cells
What are 2 things that plant cells have that animal cells do not? Cell walls and chloroplasts
What are 2 things that animal cells have that plant cells do not? Lysosomes and centriols
What is one difference between animal and plant cells? Plant cells have large central vacuoles and animal cells have small central vacuoles
What is the basic unit of all living things? Cells
What are 3 things that all cells have in common? A cell membrane, organelles, and all cells come from existing cells
What does a eukaryotic cell have that a prokaryotic cell does not? A nucleus
Name two kinds of eukaryotes that have cell walls Bacteria and archaea
What is a cell? A cell is the smallest structural and functional unit of living things
Who discovered the first cell? Robert Hooke
What discription did he compare the cell to? Little rooms-cells
Single celled organisms or protists
