Cell Size
Regarding the size of a cell, it is best for a cell to be this.
What is small?
This type of cell is known for lacking a nucleus and other membrane-bound organelles.
What is prokaryotic?
This organelle is responsible for converting light energy to chemical energy.
What is the chloroplast?
The movement of molecules from an area of high concentration to an area of high concentration.
What is diffusion?
What is a uniporter?
In cells, the value of this must be large in order to transport materials across the plasma membrane most efficiently.
What is the surface area-to-volume ratio?
This type of cell is defined by the presence of membrane-bound organelles.
What is a eukaryotic cell?
This organelle removes toxins from the cell.
What is the smooth endoplasmic reticulum?
This is the movement of molecules from high to low concentration that requires the help of a membrane protein.
What is facilitated diffusion?
This example of active transport moves three sodium ions out of the cell as it moves two potassium ions into the cell.
What is the sodium-potassium pump?
In the inner membrane of the mitochondria, these structures increase the amount of surface area.
What is folds?
You would expect to find chloroplasts in this type of eukaryotic cell.
What is plant cells?
This organelle is found in both prokaryotic and eukaryotic cells.
What is ribosomes?
Although water can pass through the plasma membrane through simple diffusion, water must make use of these membrane proteins to pass through the membrane quickly.
What is aquaporins?
This example of active transport exports materials from the cell as vesicles fuse with the plasma membrane.
What is exocytosis?
As cells get larger, their surface area-to-volume ratio gets _____.
What is smaller?
This type of cell will undergo plasmolysis when it is placed in a hypertonic solution.
What is a plant cell?
This organelle, which is full of hydrolytic enzymes, is responsible for breaking down materials in the cell.
What is the lysosome?
This is the diffusion of water molecules.
What is osmosis?
These proteins facilitate the diffusion of one substance across a membrane while simultaneously moving another substance up its concentration gradient.
What are symporters?
The surface area-to-volume ratio of a cell and cell size have a direct or inverse relationsip.
What is inverse?
This type of cell will undergo cytolysis when it is placed in a hypotonic solution.
This theory states that mitochondria and chloroplasts evolved from prokaryotic cells that were engulfed by larger prokaryotic cells.
What is the Theory of Endosymbiosis?
When there is a high concentration of a substance on one side of a membrane and a low concentration of the same substance on the other side of a membrane, this is created.
What is a concentration gradient or potential energy?
In this form of endocytosis, large molecules or even bacterial cells are engulfed by the plasma membrane and brought into the cell.
What is phagocytosis?
