BIO 1201 LICATA EXAM 2 UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS VERIFIED 2027 EDITION
1. Cell Theory
All organisms are made of cells.
2. Cell
The cell is the simplest collection of matter that can be alive.
3. Microscopy
Techniques used to visualize cells and their components.
4. Scanning Electron Microscopes (SEMs)
Focus electrons onto the surface of a specimen, providing images that look 3-D.
5. Transmission Electron Microscopes (TEMs)
Focus a beam of electrons through a specimen.
6. Cell Fractionation
Takes cells apart and separates the major organelles from one another.
7. Centrifuges
Fractionate cells into their component parts.
1
,8. Prokaryotic Cells
Cells that have no nucleus, DNA in an unbound region called the nucleoid, and no membrane-bound
organelles.
9. Eukaryotic Cells
Cells characterized by having DNA in a nucleus with a membrane and membrane-bound organelles.
10. Nucleus
Contains most of the cell's genes (DNA) and is enclosed by the nuclear envelope.
11. Nuclear Envelope
Encloses the nucleus and is a lipid bilayer.
12. Nuclear Pores
Regulate the entry and exit of molecules in and out of the nucleus.
13. Chromatin
DNA associated with proteins in the nucleus that condenses to chromosomes as a cell prepares to divide.
14. Ribosomes
Particles made of ribosomal RNA and protein that carry out protein synthesis.
2
, 15. Endoplasmic Reticulum (ER)
More than half of the total membrane in the cell, continuous with the nuclear envelope.
16. Smooth ER
Without ribosomes; synthesizes lipids, metabolizes carbohydrates, detoxifies drugs and poisons, and
stores calcium ions.
17. Rough ER
With ribosomes; has bound ribosomes that secrete glycoproteins and distributes transport vesicles.
18. Golgi Apparatus
Flattened membrane sacs called cisternae that modify products of the ER, manufacture certain
macromolecules, and sort and package materials into transport vesicles.
19. Lysosomes
Membranous sac of enzymes that can digest macromolecules.
20. Phagocytosis
Engulfing food particles or other cells that fuse with lysosomes.
