True

Question 10

System as continuation of the outer nuclear membrane is a network of membrane bound vesicles&tubules.

Answer 10

Rough endoplasmic reticulum

Question 11

Ribosomes on the cytosol surface of t rough ER give this organelle a pebbled appearance

Answer 11

Rough ER

Question 14

True or false:Ribosomes are the site for messenger RNA (mRNA) translation into proteins

Answer 14

True: ribosomes

Question 15

True or false:mRNA from cell nucleus is moved along the ribosome where transfer RNA adds single amino acid molecules to the lengthening protein chain

Lysosomes,peroxisomes, secretory visicles

Question 21

Are vesicles filled with hydrolytic enzymes

Answer 21

Lysosomes

Question 22
