ANSWERS/ ALREADY GRADED A+ (MOST RECENT!!)
Which cells are produced in the ovaries?
A. Osteoblasts
B. Prokaryotic cells
C. Epithelial cells
D. Oocyte cells -Correct Answer- D. Oocyte cells
Which term describes the dotted granules embedded in the membrane of
the rough endoplasmic reticulum (RER) in the given image?
A. Lysosome
B. Golgi apparatus
C. Mitochondria
D. Ribosome -Correct Answer- D. Ribosome
RER is studded with numerous ribosomes, which are the sites of protein
synthesis.
What is the function of lysosomes?
A. Transport proteins in and out of the cell
pg. 1
,2|Page
B. Breakdown of large cell components and old cells
C. Synthesize protein
D. Make ATP -Correct Answer- B. Breakdown of large cell components
and old cells
Lysosomes contain enzymes that break down large cell components and
old cells.
Which organelle is found on rough endoplasmic reticulum and in
cytoplasm?
A. Lysosome
B. Golgi apparatus
C. Mitochondria
D. Ribosome -Correct Answer- D. Ribosome
Ribosomes are found on rough ER and are free floating in cytoplasm.
Which type of active transport is also known as "cell drinking"?
A. Phagocytosis
B. Exocytosis
C. Pinocytosis
d. Osmosis -Correct Answer- C. Pinocytosis
Pinocytosis is a form of endocytosis that brings fluid containing
dissolved substances into a cell using vesicles.

What are the four types of tissue?
A. Epithelia, connective, muscular, skeletal
B. Epithelial, connective, skeletal, nervous
C. Epithelial, muscular, skeletal, nervous
D. Epithelial, connective, muscular, nervous -Correct Answer- D.
Epithelial, connective, muscular, nervous
Epithelia, connective, muscular, and nervous are the four types of tissue.
Which tissue type includes a single-layer, irregularly shaped columnar
cells, and nuclei appearing at different levels?
A. Simple cuboidal
B. Simple columnar
C. Simple squamous
D. Pseudostratified columnar -Correct Answer- D. Pseudostratified
columnar
Pseudostratified columnar consists of a single layer of irregularly shaped
and differently sized columnar cells with nuclei of neighboring cells
appearing at different levels.
Which type of tissue consists mostly of fat storage cells and has a large
number of capillaries that allow rapid storage and mobilization of lipid
molecules?
A. Lymph
B. Reticular
pg. 3
, 4|Page
C. Cartilage
D. Adipose -Correct Answer- D. Adipose
Adipose tissue consists mostly of fat storage cells, with little
extracellular matrix. Presence of capillaries allows rapid storage and
mobilization of lipid molecules
Which tissue protects the integral organ and mostly contains collagen
fibers?
A. Adipose tissue
B. Cartilage tissue
C. Ligament tissue
D. Skeletal tissue -Correct Answer- D. Skeletal tissue
Bone protects the internal organ and contains mostly collagen fibers.
Which cells in the central nervous system have functions including
regulation of ion concentration in the intercellular space, uptake and
breakdown of some neurotransmitters, and formation of the blood-brain
barrier?
A. Microglia cells
B. Oligodendrocyte cells
C. Schwann cells
D. Astrocyte cells -Correct Answer- D. Astrocyte cells
Astrocyte cells are named for their distinctive star shape and perform the
listed functions.
