These cells lack a nucleus, other membrane-bound organelles, and are generally unicellular and relatively simple:
What are PROKARYOTES
100
This "powerhouse of the cell" is where food molecules are converted to our energy source, ATP:
What are MITOCHONDRIA
100
This cell structure allows some materials to enter and exit the cell, and not others:
What is the CELL MEMBRANE
100
These membranous organelle has NO RIBOSOMES, and is where many lipids are synthesized and toxins removed:
What is the SMOOTH ENDOPLASMIC RETICULUM (Smooth ER)
100
This large, membranous organelle is studded with ribosomes, and is the site of membrane and proteins:
What is ROUGH ENDOPLASMIC RETICULUM (Rough ER)
200
These are the two groups that are prokaryotes:
What are: BACTERIA & ARCHAEA
200
This "stomach of cells" is a membranous vesicle filled with enzymes that can digest food particles and/or "junk" within the cell:
What are LYSOSOMES
200
This molecule is the backbone of our cell membranes. Also, please provide the arrangement that these molecules form to construct the membrane:
What is a PHOSPHOLIPID BILAYER
200
These are double-membraned organelles that take sunlight, water and CO2 and convert it to sugar and oxygen:
What are CHLOROPLASTS
200
Mitochondria & Chloroplasts are two examples of organelles hosted by our cells that HAVE THEIR OWN DNA. What theory accounts for the fact that cells that were once their own independent selves are now hosted by our cells?
What is the THEORY OF ENDOSYMBIOSIS
300
These cells contain nuclei, membrane-bound organelles and are generally multicellular and more complex:
What are EUKARYOTES
300
This is referred to as the "workbench of the cell," it is the site where proteins are made and is itself constructed of RNA & protein:
What are RIBOSOMES
300
These small compartments are how materials such as proteins get from one part of the cell to another:
What are VESICLES
300
These double-membrane organelles take sugar and oxygen and convert these to ATP, CO2 and water.
What are MITOCHONDRIA
300
This part of the phospholipid faces both the inside and the outside of the cell (where the water is):
What is the HYDROPHILIC HEAD
400
Robert Hooke discovered what he described as "cells" by observing this under the microscope:
What are CORK CELLS
400
This is a storage compartment inside cells, particularly plant cells where there is a large central version of one of these:
What is a VACUOLE
400
Plants, fungi and bacteria have these structures that provide additional support to cells. Animal cells DO NOT have these:
What are CELL WALLS
400
Microtubules and microfilaments comprise this, that part of the cell that gives it its shape:
What is the CYTOSKELETON
400
This molecule provides the instructions for how cells make proteins:
What is DNA
500
These are the three points of cell theory:
What is:
1. Cells are the basic units of structure and organization of living things (Basic Units of Life)
2. All living things are made of one or more cells
3. All cells come from pre-existing cells
500
This double-membrane organelle is the largest inside eukaryotic cells, and the site of the genetic material:
What is THE NUCLEUS
500
This organelle repackages materials after they've been produced by the ER. It is often referred to as the "post-office" of cells:
What is the GOLGI APPARATUS
500
These cell structures are constructed of microtubules, and provide many cells with movement:
What are CILIA & FLAGELLA
500
List the three structures we've heard about thus far that have 2 membranes:
