15 Questions
What is the primary role of the cell membrane in cell function?
Controlling the movement of materials in and out of the cell
Which organelle is present in the plant cell but not the animal cell?
Chloroplast; Lysosome
What is the function of the vacuole in a plant cell?
Storage of water, nutrients, and waste
According to the Kinetic Particle Theory, which physical property is fixed for gases?
Volume
In which state of matter do particles have an irregular arrangement and are very far apart?
Gas
In which form of passive transport do materials move without the need of energy due to differences in concentration?
Diffusion
In which medium will diffusion occur at the fastest rate?
Gas
When will diffusion be faster - in a hot medium or a cool medium?
Hot medium, due to increased particle movement
What is the process called when water molecules move from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane?
Osmosis
Which type of transport requires cells to use up energy to move molecules across the cell membrane against the natural concentration gradient?
Active Transport
What happens when materials that are too large to cross the cell membrane need to move into the cell?
They are moved by endocytosis.
What happens when the environment is dry and there is very little water?
Water moves out of cells causing them to shrink.
Which substances are moved in and out of cells by active transport?
Calcium, potassium, and sodium
What type of movement involves substances being too large to cross the cell membrane and therefore move out of the cell by this process?
Exocytosis
Which form of passive transport involves proteins providing a pathway for large molecules to diffuse into the cell?
Facilitated diffusion
