Answer 1

Cell Membrane

Question 2

The entire region between the nucleus and the cell membrane, consists of cytosol

Answer 2

Cytoplasm

Question 3

Contains most of the genes that control the eukaryotic cell, generally the most conspicuous organelle in a eukaryotic cell, contains nucleolus and chromatin

Answer 3

Nucleus

Question 4

Where the components of the ribosomes are synthesized and assembled, found in the nucleus

Answer 4

Nucleolus

Question 5

Consists of DNA and protein, condenses to form chromosomes

Answer 5

Chromatin

Question 6

Double membrane that forms the boundary between the nuclear contents and the cytoplasm, perforated with pores

Answer 6

Nuclear envelope

Question 7

Site of protein synthesis, suspended in the cytosol, produces proteins for use within the cell

Answer 7

Free ribosomes

Question 8

Site of protein synthesis, attached to the outside surface of the ER, produces proteins for use outside the cell of for use in the cell membrane

Answer 8

Bound ribosomes

Question 9

Sythesizes lipids including phospholipids and steroids, metabolizes carbs, detoxifie drugs and poisons, stores calcium ions, lacks attached ribosomes

Answer 9

Smooth ER

Question 10

Consists of flattened membranous sacs, receivers transport proteins from the ER, modifies ER products, produces certain molecules, produces lysosomes and secretory proteins

Answer 10

Golgi apparatus

Question 11

Channels proteins to transport vesicles, attaches carbs to some proteins, involved in membrane production through the production of vesicles, has attached ribosomes

Answer 11

Rough ER

Question 12

Carries ER products to the Golgi

Answer 12

Transport vesicle

Question 13

Carries Golgi modified products to the cell membrane, fuses with the cell membrane releasing the contents to the outside of the cell
