15 Questions
What is the primary function of the cell membrane?
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 and nutrients
According to the Kinetic Particle Theory, which physical property is fixed for a gas?
Volume
In which state of matter do particles have an irregular arrangement and are very far apart?
Gas
Which type of particle movement is characteristic of a liquid?
Roll and move around each other
What type of bond exists between particles in a gas?
Little or no bond between particles
In which form of passive transport do materials move without the need of energy?
Diffusion
Which medium will allow the fastest diffusion?
Gas, due to very far apart particle arrangement
Will diffusion be faster when the medium is hot or cool?
Hot, because particles move faster at higher temperatures
What is the movement involved in osmosis?
Movement of water molecules from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane
What happens to cells when the environment is dry with very little water?
Water may move out of cells, causing cytoplasm to shrink away from the cell wall and potentially leading to cell death
What do proteins do in facilitated diffusion?
Provide a pathway for large molecules to diffuse into the cell
What is involved in active transport?
Cells use up energy to move molecules across cell membranes against natural concentration gradient
How do large materials like food particles enter cells?
Through endocytosis and exocytosis
