organelles

Question 1

mitochondria

Answer 1

highly folded inner membrane surrounded by the second outer membrane
site of aerobic cellular respiration (produces ATP)

Question 2

golgi body

Answer 2

stacked flattened sacs that are the sites of protein sorting, packaging and modification

Question 3

nucleus

Answer 3

is surrounded by a double membrane
protects the DNA of the cell
inside the nucleus is a smaller structure called a nucleolus (site of ribosome production)

Question 4

rough endoplasmic reticulum

Answer 4

a membranous chain of connected and flattened sacs which are coated with ribosomes
synthesising and modifies proteins

Question 5

smooth endoplasmic reticulum

Answer 5

a membranous chain of connected and flattened sacs that is NOT coated with ribosomes
responsible for production of lipids

Question 6

chloroplast

Answer 6

a double membrane-bound organelle that contains flattened, fluid-filled sacs
is the site of photosynthesis

Question 7

cell wall

Answer 7

a sturdy border outside the plasma membrane outside plasma membrane that provides strength and structure the plant

Question 8

large vacuole

Answer 8

a membrane-bound sac that is used for water and solute storage
maintains plant cell structure

Question 9

ribosome

Answer 9

tiny structures made of rRNA and proteins
freely float in cytoplasm or attached to rough ER
building blocks to make proteins

Question 10

lysosome

Answer 10

membrane bound vesicle containing digestive enzymes

Question 11

plasma membrane

Answer 11

a selectively permeable barrier between the intracellular and extracellular fluid, made of a phospholipid bilayer
