CELL THEORY
|
1. All Organisms are made up of cells
2. A cell is the structural and functional unit of organs and organisms 3. Cells are capable of self reproduction 4. Cells come only from preexisting cells |
|
SUBSTANCE SIZES
|
1. Subatomic Particles- proton, neuron, electron
2. Atoms- Hydrogen, oxygen, carbon, etc. 3. Molecules- Water, carbon dioxide, etc. 4. Macromolecules- Proteins, sugars, amino acids, etc. 5. Cells- amoeba, muscle cell, nerve cell, etc. 6. Tissues- Muscle, nerve, bone, etc. 7. Organs- Lung, heart, etc. 8. Organisms- Human, bird, etc. |
|
Small, specialized membrane sacs that contain digestive enzymes are called
|
lysosomes and peroxisomes.
|
|
The nucleus of the cell contains
|
Chromatin, Chromosomes, DNA
|
|
What is the inner portion of the mitochondrion called?
|
Matrix
|
|
Microtubules appear to originate from what cell structure?
|
Centriole
|
|
What type of cell would be considered to be the most complicated or "advanced"?
|
Eukaryotic
|
|
What type of cell is characterized by the following list of features?
1.No nucleus (DNA is not surrounded by a membrane) 2.Simple structure (less division into internal compartments) 3.Typical types of organisms - Bacteria and Blue-green Algae |
Prokaryotic
|
|

|
|
Which of the following is not a difference between a plant cell and an animal cell?
|
Cell wall
Chloroplast Chlorophyll Vacuole ***Plasma membrane*** |
|
Which of the following lists represents the structural components of the cell arranged in ascending order of size?
|
Actin filaments, intermediate filaments, microtubules
|
|
A stack of associated membranes in the cell that package, condense, and modify cell substances is called the
|
Golgi Apparatus
|
|
Chlorophyll molecules are
|
Embedded on the outer surface of the thylakoid membranes.
|
|
As cell size decreases, the surface-to-volume ratio
|
Increases
|
|
A system of membranes extending throughout the cell that serves as the sight for protein synthesis is called the
|
Endoplasmic Reticulum
|
|
Which of the following lists is representative of a prokaryotic cell?
|
Ribosomes, thylakoids, nucleoids
|
|

|
Molecule, macromolecule, cell, tissue, organ
|
|
Which of the structural support components of the cell is associated with cilia and flagella?
|
Microtubules
|
|
Cells are required to be in relatively close contact with their environment, either directly or indirectly, because
|
They need to obtain nutrients and get rid of wastes.
|
|
Which of the following lists represents the components of the chloroplast arranged in order from smallest to largest?
|
Thylakoid, granum, stroma
|
