Chapter 2 (CELL CYTOPLASM) - Histoworld

Question 1

Which of the following is NOT a membranous organelle?

Answer 1

Ribosomes

Question 2

Which organelle contains digestive enzymes?

Answer 2

Lysosome

Question 3

Which organelle is considered the powerhouse of the cell?

Answer 3

Mitochondria

Question 4

What structure is at the base of cilia?

Answer 4

Centrioles

• Peroxisomes contain enzymes for detoxification. One of the enzymes within peroxisomes is catalase. Catalase is involved in the breakdown of hydrogen peroxide. Microfilaments are made of actin. They form the cells cytoskeleton Centrioles are composed of microtubules. Centrioles are at the base of cilia and flagella. They are also involved with cell division.

Question 5

Which of the following is NOT considered an inclusion?

Answer 5

Mitochondria

• Mitochondria are organelles. Organelles perform an activity; they have a job; they require energy.Pigment, glycogen, lipid, and secretory granules are all inclusions. Inclusions are for storage. Inclusions do not perform an energy requiring job.

Question 6

Collectively, what is the cytoplasm and nucleus called?

Answer 6

Protoplasm

• Cell boundary is defined by the cell membrane or plasmalemma. Glycocalyx is a polysacchride that can be found on the outer surface of the cell membranes. The cytoplasm and nucleus form the protoplasm of a cell. The folds on the inner mitochodrial membrane are called cristae. The cytoplasm that surrounds organelles is the cytoplasmic ground substance or cytosol.

Question 7

How thick is the plasma membrane?

Answer 7

8 - 10 nanometers

Question 8

What is the term for the general process that cells use to expunge material from the cell?

Answer 8

Exocytosis

• Endotyosis is the term for the process cells use to have substances enter them. Exoctyosis is the term for the process cells use to remove substances. Phagocytosis is “cell eating” and is used for the transport of particulate matter. Pinocytosis is “cell drinking”. Active transport is a method which requires energy.

Question 9

Which is organelle sorts and packages proteins within a cell?

Answer 9

Golgi apparatus

Question 10

Which of the following is NOT a membranous organelle?

Answer 10

Filaments

Question 11

What are the folds on the inner mitochondrial membrane called?

Answer 11

• Cristae

Question 12

Which organelle is involved in lipid metabolism?

Answer 12

Smooth endoplasmic reticulum

Question 13

Which organelle contains detoxifying enzymes?

Answer 13

Peroxisome

Question 14

Which of the following is NOT a membranous organelle?

Answer 14

Microtubules

Question 15

What is the limiting membrane of a cell?

Answer 15

Plasmalemma

Question 16

What is also called a low resistance junction?

Answer 16

Gap junction

Question 17

What is the term for the general process that cells us to bring things into the cell?

Answer 17

Endocytosis

Question 18

Which organelle produces protein for export?

Answer 18

Rough endoplasmic reticulum

Question 19

Where are ribosomes constructed?

Answer 19

Nucleoli

Question 20

What is the term for the process used by cells for the transport in of particulate matter?

Answer 20

Phagocytosis

Question 21

What is the small clear space within a cell?

Answer 21

Vacuole

Question 22

Which of the following is NOT a membranous organelle?

Answer 22

Centrioles

Question 23

What is the polysaccharide coating that is sometimes found on the cell membrane?

Answer 23

Glycocalyx

Question 24

What process is nicknamed “cell drinking”?

Answer 24

Pinocytosis

Question 25

Which organelle is studded with ribosomes?

Answer 25

Rough endoplasmic reticulum

Question 26

Where is the site of protein synthesis?

Answer 26

Ribosomes

Question 27

What structure contributes to the cells cytoskeleton?

Answer 27

Microfilaments
