Concept 1
Plant cells perform photosynthesis. This occurs in which organelle?
chloroplast
What type of transport requires a cell to use energy?
Active transport
The process of undergoing programmed cell death.
apoptosis
Which cell organelle is used to move fluid across the cell membrane?
cilia
Which level of organization forms the fundamental base for all other levels in the hierarchy of life?
cell
Cells often store materials like water, salts, proteins, and carbs in sac-like structures called ___________.
vacuoles
This process occurs when the cell uses energy to bring something in from outside the cell.
Endocytosis
Substances known to produce or promote cancer.
carcinogens
Which of the following is found in a eukaryotic cell, but is not found in a prokaryotic cell?
cytoplasm, cell membrane, nucleus, flagella
nucleus
Which organelle is critical for cell division?
centrioles
Which part of the cell theory supports the idea that new cells replace damaged cells in a scraped knee?
All cells come from other cells.
Explain the 3 types of osmotic solutions.
Hypotonic: more water in the cell;swells
Hypertonic: less water in the cell;shrivels
Isotonic: water [] is same;no change
growth and repair
If a cell has 16 chromosomes, how many chromosomes will each of its daughter cells have after cytokinesis?
16
In what two places in the cell can you find ribosomes?
cytoplasm and rough ER
What consequences will a cell face if it lacks lysosomes?
Won't be able to break down dead materials or perform programmed cell death.
Name which type of transport is used for each of the following:
a. moving O2 and CO2
b. moving glucose
c. white blood cell capturing bacteria
d. water moving into a cell
a. diffusion
b. facilitated diffusion
c. endocytosis
d. osmosis
If a cell fails to go through the S phase of interphase, what could be wrong with the daughter cells?
They will have the wrong number of chromosomes.
Organize the parts of this body system from most basic to most complex according to the levels of organization in a multicellular organism.
human being, brain, brain cell, nervous system, nerve tissue
brain cell --> nerve tissue --> brain --> nervous system --> human being
List and describe the last stage of the cell cycle.
Cytokinesis: cytoplasm divides into 2 separate cells
What are 3 differences and 2 similatities between prokaryotic and eukaryotic cells?
Differences: no nucleus/nucleus, binary fission/mitosis, no membrane bound organelles/membrane bound organelles
Similarities: genetic information, cytoplasm, cell membrane, ribosomes
Describe a feedback look and give 2 examples.
Positive: output of a system intensifies the response; child birth and fruit ripening
Negative: output of a system causes a counter reponse to return to a set point; body temps and blood sugar
List and describe the 1st stage of the cell cycle and its 3 subphases.
Interphase: growth phase
G1: cell growth and make proteins
S: DNA replication
G2: more cell growth
List and describe the 2nd stage of the cell cycle and its 4 subphases.
Mitosis: division phase
Prophase: chromosomes condense, spindle fibers form, nuclear membrane disappears
Metaphase: chromosomes line up in middle of cell
Anaphase: chromosomes are pulled apart
Telophase: chromosomes decondense, spindle fibers breakdown, nuclear membrane reappears
Why is it important for cells of multicellular organisms to undergo mitosis?
Mitosis produces cells that are identical to the original dividing cell.
