Eukaryotic Cell Structure and Function

Question 1

control center of the cell that contains DNA

Answer 1

Nucleus

Question 2

inside nucleus, makes ribosomes

Answer 2

Nucleolus

Question 3

phospholipid bilayer that surrounds all cells and regulates what enters and leaves the cell

Answer 3

Cell membrane

Question 4

powerhouse of the cell, organelle that is the site of ATP energy production (cellular respiration)

Answer 4

Mitochondria

Question 5

the most numerous organelle in most cells

Answer 5

Ribosomes

Question 6

are found free-floating in the cytoplasm or attached to the endoplasmic reticulum

Answer 6

Ribosomes

Question 7

Tiny organelles that link amino acids together to form proteins

Answer 7

Ribosomes

Question 8

surrounds the cytoplasm of a cell and acts as a flexible barrier

Answer 8

Cell membrane

Question 9

A cell structure that is attached to the nuclear membrane that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another

Answer 9

Endoplasmic Reticulum (ER)

Question 10

An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down.

Answer 10

Smooth Endoplasmic Reticulum (SER)

Question 11

System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm

Answer 11

Rough Endoplasmic Reticulum (RER)

Question 12

organelle in cells that modifies, sorts, and packages proteins and other materials sent from the endoplasmic reticulum for storage in the cell or release outside the cell

Answer 12

Golgi apperatus
