18 Questions
What is the primary role of the cell membrane in cell function?
Regulating the movement of materials in and out of the cell
Which organelle is present in the plant cell but not the animal cell?
Chloroplast, Golgi apparatus
What is the function of the vacuole in a plant cell?
Storage of water, nutrients, and waste products
According to the Kinetic Particle Theory, which state of matter has particles with fixed shape and volume?
Solid
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
Which medium allows the fastest diffusion of molecules?
Gas
Will diffusion be faster when the medium is hot or cool?
Hot, because particles move faster at higher temperatures
What is the movement of water molecules from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane called?
$ ext{Osmosis}$
$ ext{Facilitated diffusion}$ allows small molecules like oxygen, carbon dioxide, and water to freely diffuse across cell membranes, while larger molecules like sugar require:
Active transport to cross the membrane
What type of transport requires cells to use up energy to move molecules across the cell membrane against the natural concentration gradient?
Active transport
What process involves materials being too large to cross the cell membrane and therefore moving into or out of the cell by forming vesicles?
Endocytosis and exocytosis
Which substances are moved in and out of cells by active transport?
Calcium, potassium, and sodium
What happens when the environment is dry with very little water for cells?
Water may move out of cells causing cytoplasm to shrink away from the cell wall leading to cell death
What are the 4 functions of cell division?
Repair injured body parts
Which structures in the cell help it to reproduce?
Centrioles
During which stage of mitosis do fibers of the centrioles pull the chromatids apart into each side of the cell?
Anaphase
What happens during interphase in preparation for cell division?
Cell grows and produces organelles needed by both daughter cells
