SB1a - Cell Structures

A prokaryote is an organism that

• lacks a cellular 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
• cell wall
• central vacuole
• all of the above

A bacteria cell is most likely classified as a(n):

• eubacterial cell
• archaea bacterial cell
• prokaryote
• eukaryote

Proteins are made on the

• nucleolus
• golgi appratus
• chromosomes
• ribosomes

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

• vacuoles
• ribosomes
• lysosomes
• flagella

Some cells, such as human nerve cells and human muscle cells, contain more mitochondria than other cells, such as skin cells. Why do some cells have more mitochondria than others?

• The cells use more energy than others.
• The cells store more nutrients than others.
• The cells degrade more proteins than others.
• The cells divide more frequently than others.
