Cell & Cell Transport Practice

A prokaryote is an organism that

• lacks a nucleus

• has a cell wall

• is very small

• all of the above

An example of an organelle seen in plant cells, but NOT seen in animal cells is:

• chloroplasts

• a cell wall

• central vacuole

• all of the above

The first cell that ever existed on earth most likely

• was very tiny

• lacked a nucleus

• lacked DNA

• was very tiny and lacked a nucleus

A cell that has complex organelles is most likely a(n):

• bacteria cell

• prokaryotic cell

• eukaryotic cell

• cyanobacterial cell

The difference between smooth and rough ER is that

• smooth ER has no role in the cell

• rough ER produces vesicles

• rough ER has ribosomes on its surface

• smooth ER never touches the nucleus

The role of the ______________________ is to produce and store RNA.

• nucleus

• nucleolus

• ribosomes

• smooth ER

Proteins are made by

• nucleolus

• golgi apparatus

• chromosomes

• ribosomes

The function of the Golgi apparatus is to

• control the cell's functions

• package and distribute proteins

• store water

• allow things in and out of the cell

Vesicles that contain powerful enzymes used to break down substances are called

• vacuoles

• ribosomes

• lysosomes

• flagella

The organelles that captures energy from the sun to make organic compounds are

• lysosomes

• vasicles

• vacuoles

• chloroplasts
