25
What process requires the cell to expend metabolic energy?
Active transport
26
What is it called when a cell nucleus divides and complete sets of chromosomes move to each end of the cell?
Mitosis
27
What is the phase called where chromatids are positioned along the equator of the cell, and spindles attach to the centromere?
Metaphase
28
What protects the body by covering all free surfaces and lining cavities?
Epithelium
29
What is active transport?
When a cell uses energy to move materials across a concentration gradient
30
What part of the cell processes and packages proteins?
The Golgi complex
31
What is adipose?
It stores fat as the body needs energy and provides insulation.
32
What membrane lines body cavities that do not open to the outside of the body?
Serous
33
Where does cellular respiration take place?
The mitochondria
34
What are the organelles called that function as factories to manufacture proteins?
Ribosomes
35
What is a small membrane-enclosed structure that holds or transports cargo within the cell?
A vesicle
36
What kind of epithelium cells appear hexagonal in a cross-section and may contain cilia?
Columnar
37
The sequence of the stages of mitosis is what?
Prophase, Metaphase, Anaphase, Telophase
38
What kind of epithelium cells are thin and flattened?
Squamous
39
Researchers use the greater resolving power of a __________ to discern the fine details of thin cross-sections of cells.
Transmission electron microscope
40
What does the intercellular matrix consist of?
secreted matrix
41
Active transport in which a plasma membrane traps drops of fluid is called what?
Pinocytosis
42
What is the phase called where chromosomes begin to uncoil and disperse, and spindles disappear?
Telophase
43
What membrane lines body cavities that are open to the outside of the body?
Mucous
44
What is the final step called in reception?
Response
45
Which tissues join other body tissues and provide a framework that supports and protects the organs?
Connective tissues
46
What connective tissue membrane lines the joint cavities?
Synovial
47
Reception of cells involves what specific cells?
Target cells
48
What are duplicated chromosome pairs called?
Sister chromatids
49
What is the difference between cilia and flagellum?
Cilia are on smaller, flagella are specific to sperm.
50
When active transport occurs, what is pumped into the cell, and what is pumped out of the cell?
``` In = potassium ions Out = sodium ions ```
51
What is diffusion?
The net movement of molecules down a concentration gradient
52
What process is it called when a receptor converts a signal outside of the cell to a signal inside the cell that affects cellular process?
Signal transduction
53
Which glands have ducts, and most of them are multicellular?
Exocrine
54
What separates connective tissues?
intercellular substance
55
What is histology?
The microscopic study of tissue
56
What makes up the cytoskeleton?
A dense network of protein filaments
57
What provides structural support for the cell?
The cytoskeleton
58
What is the phase called where sister chromatids separate and become independent chromosomes?

Elastic
68
Target cells receive the signal in a process called what?
Reception
