Cell Transport
This type of transport moves substances from an area of high concentration to an area of low concentration without requiring cellular energy.
passive transport
This is the movement of water across a selectively permeable membrane.
osmosis
During this stage, the cell grows and copies its DNA.
interphase
What is the correct order for the stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase
As a cell gets larger, this ratio decreases, making it harder for the cell to exchange materials efficiently.
surface-area-to-volume ratio
This type of diffusion uses a transport protein to move a substance from high concentration to low concentration.
facilitated diffusion
A solution has a higher concentration of dissolved substances outside the cell than inside the cell. This type of solution surrounds the cell.
hypertonic solution
This molecule becomes active or inactive at checkpoints and helps control the cell cycle.
cyclins
During this stage, chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.
prophase
This molecule limits cell size because a cell must have enough genetic information to control its activities.
DNA
This type of transport requires energy and moves substances from an area of low concentration to an area of high concentration.
active transport
In this type of solution, the concentration of dissolved substances is the same inside and outside the cell.
isotonic solution
This stage of the cell cycle includes G₁, S, and G₂ phases.
interphase
During this stage, chromosomes line up across the middle of the cell.
metaphase
This factor can limit cell size because materials need time to move throughout the cell.
time required for diffusion
When a cell takes in a large particle by engulfing it and forming a vesicle, this process occurs.
endocytosis
In this type of solution, the concentration of dissolved substances is lower outside the cell than inside the cell.
hypotonic solution
The cell cycle is controlled by checkpoints and proteins to prevent this type of uncontrolled cell division.
cancer/uncontrolled cell division
During this stage, sister chromatids separate and move toward opposite sides of the cell.
anaphase
These structures help organize chromosome movement during cell division in animal cells.
centrioles
When a cell releases materials outside the cell by using a vesicle that fuses with the cell membrane, this process occurs.
exocytosis
A cell is placed in a hypotonic solution. Water moves into the cell, causing the cell to swell. If enough water enters, this can happen.
cell bursting/lysis
DNA replication occurs during this part of interphase.
S phase
During this final stage of mitosis, new nuclear envelopes form around the chromosomes.
telophase
A selectively permeable bag contains iodine solution. The bag allows small iodine molecules to pass through but does not allow large starch molecules to pass through. The bag is placed in a starch solution.
Question: What will happen?
Iodine will move through the membrane from the bag into the starch solution, while the larger starch molecules will not move through the membrane?
