Question

what does the term endocytosis mean? what does the term exocytosis mean? describe the process of endocytosis: describe the process of exocytosis: what is pinocytosis? station five: osmosis instruction: read the below information provided and answer the following questions at the end of the text. osmosis is a specialized case of diffusion that involves the passive transport of water across the cell/plasma membrane. in osmosis, water moves through a selectively permeable membrane from a region of higher concentration (more water) to a region of lower concentration (less water). try to remember it as h2osmosis. the cell membrane is selectively permeable which means it allows passage of certain types of molecules while restricting the movement of others. water is allowed to pass freely, and without using energy, through the cell/plasma membrane. therefore, osmosis if a form of passive transport. if there was a membrane with twice as many water molecules on one side as there were on the other (and remember, water can move freely through the membrane), what do you think would happen to the water molecules? the side with twice as many water molecules would move in one direction to the other side where the concentration was lower until eventually causing the concentration of water to be equal or in equilibrium on both sides. after that the flow of water would then diffuse through the membrane in both directions to maintain equilibrium. remember: water is considered the universal solvent. while discussing osmosis, when we use the word -solves we will always be referring to water (ex. salt solution, sugar solution...)

Explanation:

Endocytosis is the process by which a cell takes in substances by engulfing them with its cell - membrane. Exocytosis is the process by which a cell releases substances out of the cell by fusing a vesicle containing the substances with the cell - membrane. Pinocytosis is a type of endocytosis where the cell takes in extracellular fluid and dissolved solutes. Osmosis is the passive transport of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

Answer:

What does the term Endocytosis mean? - The process by which a cell takes in substances by engulfing them with its cell - membrane.
What does the term Exocytosis mean? - The process by which a cell releases substances out of the cell by fusing a vesicle containing the substances with the cell - membrane.
Describe the process of endocytosis: - The cell membrane invaginates around the substance to be taken in, forms a vesicle, and brings the substance into the cell.
Describe the process of exocytosis: - A vesicle containing the substance to be released fuses with the cell membrane, and the contents are expelled out of the cell.
What is pinocytosis? - A type of endocytosis where the cell takes in extracellular fluid and dissolved solutes.
If there was a membrane with twice as many water molecules on one side as there were on the other: - Water would move from the side with higher water concentration (twice as many water molecules) to the side with lower water concentration until equilibrium is reached, and then water would diffuse in both directions to maintain equilibrium.
