What is the process that produces specialized cells with different structures and functions?
cell differentiation
What is the maintenance of stable internal conditions in a cell or organism called?
homeostasis
What is the order of the mitosis stages?
PMAT (prophase, metaphase, anaphase, and telophase)
How do eukaryotic organisms differ from prokaryotic organisms?
Prokaryotic organisms are not made up of cells.
Prokaryotic organisms do not carry genetic information.
All eukaryotic organisms have many cells, and prokaryotic organisms only have one.
Prokaryotic cells do not have nuclei
Prokaryotic cells do not have nuclei
Which structures are least likely to appear in the same eukaryotic cell?
Mitochondria & chloroplasts
Ribosomes & mitochondria
A cell wall and chloroplasts
Small vacuoles & cell wall
small vacuoles and a cell wall
How does the structure of the red blood cell help it to perform its function?
The small size and flat disk shape helps red blood cells move easily through the thin blood vessels.
What are the conditions that a cell must regulate to maintain homeostasis?
pH, temperature, glucose, and acids/bases
When does mitosis occur during the cell cycle?
After the G2 stage and before cytokinesis
Where is DNA found in a prokaryotic cell?
floating in the cytoplasm
Which of the following structures separates the nucleus from its environment?
Cell wall
Plasma membrane
Nuclear membrane
Endoplasmic reticulum
nuclear membrane
What are the two kinds of specialized cells present in plants?
xylem and pholem
What is the plasma membrane made up of?
Two layers of lipids, called a lipid bilayer.
In which phase of the eukaryotic cell cycle is the genetic material duplicated?
mitosis
True or False: All eukaryotes are multicellular organisms.
false
A student is using a microscope to examine an unlabeled slide of a cell. Which of these structures suggest that the student is looking at a plant cell?
Chloroplasts and cell wall
Ribosomes and cytoplasm
Nuclei and vacuoles
Chromosomes and mitochondria
chloroplats and cell wall
Although most of a body’s cells contain the same DNA, how does each cell become specialized?
Each cell only uses the part of the genetic information that they need.
How does the plasma membrane help maintain homeostasis?
It regulates which materials enter and leave the cell.
What is the major difference between mitosis and meiosis?
Mitosis is the division of somatic (body) cells and meiosis is the division of gametes
An organism found in pond water has a cell wall and circular DNA, but no nuclear membrane. How is this organism best classified?
prokaryotic
Within a cell, DNA provides the information needed for the cell to make proteins. Which of the following are the organelles that are most involved in these processes?
Chloroplasts and vacuoles
Plasma membrane and plasmid
Nucleus and ribosomes
Chloroplasts and mitochondria
nucleus and ribosomes
What are the three types of cells that form within the ball of cells after fertilization?
mesoderm, endoderm, and ectoderm
What are the two ways that materials passively enter and leave a cell?
diffusion and osmosis
What does crossing-over increase the number of?
Possible genetic combinations in the offspring
