Chapter 4 quiz biology

Which feature is found in all cells ?

Oplasma membrane composed of phospholipids

Prokaryotic

Bacterial comparatively small Lack a membrane bound nucleus

The main structural component of a plant cell wall is .

Cellulose

It converts light energy into chemical energy .

Cholorplast

Both

Filled with cytoplasm Plasma membrane Chromosomes

Site of cellular digestion such as breaking down excess or worn - out cell parts

Lysosomes

Produces ATP

Mitochondria

Eukaryotic

Plant and animal cells Membrane bound nucleus Contain many specialized organelles

Protein synthesis

Ribosomes

Synthesis and transports of lipids

Smooth endoplasmic reticulum

As a molecule moves through the plasma membrane it passes through

a hydrophilic layer of phospholipid heads , then a hydrophobic layer of phospholipid tails , and then another hydrophilic layer of phospholipid heads .

There is an antibiotic called streptomycin that inhibits the function of bacterial ribosomes . Consequently as the bacterial cells die , the person taking the antibiotics gets better . In other words , the antibiotic destroys bacteria by

not allowing them to produce proteins .

Which of the following structures would NOT be found in a prokaryotic cell ?

nucleus

What must materials pass through to enter or leave a cell?

plasma membrane

Modifies the contents within vesicles and then repackages them for export

✓Golgi apparatus

Since the plasma membrane blocks the passage of all but a few molecules with specific traits , it is necessary for other molecules to

O pass through the membrane via proteins ,
