22. This organelle is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. Sometimes called “jelly-like”.
chromatin
plasma membrane
cytoplasm
nucleolus
Which of the following types of cells utilize DNA as their genetic material but do not have their DNA encased within a nuclear envelope?
plant
bacteria
animal
fungi
16. Since the digestion process occurs once food enters our mouth, which organelle in our cells would be the most plentiful to speed up the role?
Golgi bodies
ribosomes
cytoplasm
chromatin
14. Plant cells use sunlight to make their own food. Which structure allows plant cells to perform this function?
Chloroplast
mitochondria
nucleus
vacuole
17. Which cell would have a large amounts of Smooth ER?

1. When we are in homeostasis, we are....
healthy, in our normal state
staying at home
not healthy, sick
dead or deceased
21.These structures are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. They have been known to store water, small bits of food or even small amounts of waste.
vacuoles
cytoplasm
peroxisomwa
lysosomes
20. This structure is generally a series of connected flattened sacs. It plays a central role in the synthesis and export of proteins or other macromolecules and is known for containing knobs all over them called ribosomes.
Smooth Endoplasmic Reticulum
. Rough Endoplasmic Reticulum
peroxisomes
lysosomes
12. The Golgi Body is broken down during mitosis & then reformed. Which function would a cell be unable to perform during the time that its Golgi Body is not functioning?
Correcting errors in the process of building a new cell
Processing & packaging proteins for cellular export
Forming vesicles to import molecules into the cell
Copying genetic material to include in the new cell
13. Organelle containing a large range of digestive enzymes used primarily for digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses or bacteria
mitochondria
cell membrane
lysosome
cell wall
2. Sweating is a form of homeostasis....
yes
no
23. A married couple brings in their 3 month old son to your office. The baby exhibits the following symptoms: small stature for age and severely underweight. A cell culture of the child shows there is extra waste products found in the
