Question 1: Nucleus

Answer:

Organelle; Contains DNA organized in masses of chromosomes

Question 2: Eukaryotic Cells

Answer:

Membrane-enclosed nucleus and a series of membrane bound organelles that carry out the functions of the cell as directed by the nucleus; more complex than prokaryotic cells

Question 3: Chromosome

Answer:

Contains all material for the regeneration of the cell, as well as all instructions for the function of cell; chromosome number is specific to species

Question 4: Cellular Membrane

Answer:

Most important component of cell; consists of a bilayer of phospholipids with proteins, cholesterol, and glycoproteins throughout; contributes to protection, communication and passage of substances into and out of the cell body

Question 5: Ribosome

Answer:

Organelle; Reads RNA produced in the nucleus and translates the genetic instructions to produce proteins. Found in two locations: bound to the endoplasmic reticulum (ER) and free floating in cytoplasm; both are interchangeable and have identical structures

Question 6: Prokaryotic Cells

Answer:

Lack a defined nucleus and do not contain membrane-bound organelles

Question 7: Golgi Apparatus

Answer:

Organelle; transports materials from the ER throughout the cell (packaging, processing, shipping)

Question 8: Organelle

Answer:

"Little organs"; any number of organized or specialized structures within a living cell

Question 9: Smooth ER

Answer:

ER membrane lacking ribosomes; functions as the detoxification and metabolism of multiple molecules

Question 10: Lysosomes

Answer:

Organelle; responsible for intracellular digestion

Question 11: Mitochondria

Answer:

Organelle; found in eukaryotic cells and are the site of cellular respiration

Question 12: Rough ER

Answer:

ER membrane covered with ribosomes; responsible for protein synthesis and membrane production

Question 13: Endoplasmic Reticulum (ER)

Answer:

Organelle; membrane attached to the nuclear membrane consisting of two continuous parts: rough ER and smooth ER

Question 14: Chloroplast

Answer:

Organelle; found in plants and are the site of photosynthesis

Question 15: Vacuoles

Answer:

Organelle; membrane enclosed, depending on cell type, have different functions-disposal, protection, hydrolysis, and storage

Question 16: The Cell

Answer:

The fundamental unit of biology; prokaryotic and eukaryotic
