Cells

Question 1

Intracellular

Answer 1

Refers to the inside of the cell

Question 2

Semi-permeable

Answer 2

Property of the cell membrane that describes the ability to allow certain elements to pass through while not allowing others to do so.

Question 3

Celia

Answer 3

Hair like structures moving in a coordinated sweeping motion to move fluids over the surface of tissues.

Question 5

Rough ER

Answer 5

Contains ribosomes

Question 6

Cytoplasm

Answer 6

The fluid like material in which the contents of the cell are contained.

Question 8

Ribosomes

Answer 8

Are the protein factories of the cell.

Question 9

ER

Answer 9

The network of pathways through which substances move.

Question 10

Golgi Apparatus

Answer 10

Concentration and packing secretions such as hormones and enzymes that are released for secretions out of the cell.

Question 11

Lysosomes

Answer 11

Dispose of the cell waste using enzymes to breakdown nutrients and foreign particles (such as bacteria) Destroy older worn out parts of the cell

Question 13

Microfilaments

Answer 13

Provides cell movement and contraction via interaction with actin and myosin.

Question 14

Thick filaments

Answer 14

Massive bundles of subunits called myosin. Appear in muscle cells only. Interact with actin to produce powerful contractions.

Question 16

Vesicles

Answer 16

Sacs that are formed when part of the cell folds inwards. Contain various liquid or solid substances that formerly existed outside the cell.

Question 17

Nucleus

Answer 17

Contains genetic instructions needed to synthesize proteins that determine cell structures and functions. These instructions are stored in the chromosomes.

Question 18

Peroxisomes

Answer 18

Contains enzymes that speed up biochemical reactions. They are abundant in the liver and kidneys. Actions include the synthesis of bile acids, detoxification of hydrogen peroxide of alcohol and break down of lipids and biochemicals.

Question 19

Anaerobic Metabolism

Answer 19

Production consisting of pyruvic acid, CO2 and4 molecules of ATP.

Question 21

Nucleolus

Answer 21

Mini nucleus. Ribosomes form inside and migrate out to the cells.

Question 22

Cellular Respiration

Answer 22

Process in which cells use glucose and oxygen to release energy from organic compounds.

Question 23

Smooth ER

Answer 23

Lacks ribosomes

Question 24

Aerobic Metabolism

Answer 24

Production of ATP releasing CO2, water and 32-34 molecules of ATP. (Krebs Cycle)

Question 25

Hypotonic

Answer 25

Solution with a lower concentration (Salt)

Question 26

Meiosis

Answer 26

Cell division that occurs in the production of the eggs and sperm.

Question 27

Neoplasm

Answer 27

Mass of tissue produced by abnormal cell growth.

Question 28

Glycolysis

Answer 28

Anaerobic breakdown of sugar for use in production of energy.

Question 29

Mitosis

Answer 29

Cell division in which the nucleus divides.

Question 30

Osmosis

Answer 30

Passive movement of a solvent or liquid from and area of a low solute concentration to an area of high concentration.

Question 31

Isotonic

Answer 31

Solution with an equal concentration

Question 32

Hypertonic

Answer 32

Solution with a higher concentration (Salt)

Question 33

Cell Membrane

Answer 33

Contains molecules that form pathways that allow movement into and out of the cell. Also called plasma

Question 34

Mitochondria

Answer 34

Powerhouse of the cell. Have double membranes that play a central role in the production of energy.

Question 36

Extracellular

Answer 36

Refers to the outside of the cell
