What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution?

What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution?

When a unicellular organism is exposed to hypotonic solution, water will move inside the organism. If this happens for an extended period of time, the unicellular organism would swell and then burst. Thus, the correct answer is It would swell and then burst.

How does this help them to maintain internal homeostasis in hot climates?

Answer: This help them to maintain internal homeostasis in hot climates by retaining water .

What movement of particles would be most affected by a disorder that causes damage to carrier proteins?

active transport

Which process is characterized by the movement of particles from an area of high concentration?

The passive transport is a process which is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy because, its particle move by themselves due to entropy.

What is it called when molecules move from low to high concentration?

Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.

When the concentration of dissolved particles is the same throughout a solution the system is said to be in?

10th grade Biology – 7-3 Cell Boundaries

A B
when the concentration of the solute is the SAME throughout a system, the system has reached equilibrium
particles tend to move from an area where they are MORE concentrated to an area where they are LESS concentrated, is a process of diffusion

Which solution has the highest concentration of solute?

Hypertonic

Where is the highest water concentration?

Water molecules move into and out of the cell at an equal rate, so the cell’s size remains constant. than a cell. This means water concentration is higher inside the cell than outside.

What solution has the highest concentration of particles?

hypertonic solution

How do simple and facilitated diffusion differ?

Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.

How do diffusion and facilitated diffusion differ?

Diffusion is the movement of molecules from an area where the molecule is in high concentration to an area where the molecule is in lower concentration. Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier.

In which solution will water move into a cell?

Did water flow in or out of the plant cells?

But if a plant cell is placed in hypotonic solution the water will move inside and the cell will become turgid as it possesses a cell wall. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.

What type of solution do plant cells prefer?

hypotonic

Why do plant cells want to be turgid?

When water moves into a plant cell, the vacuole gets bigger, pushing the cell membrane against the cell wall. The force of this increases the turgor pressure within the cell making it firm or turgid . The pressure created by the cell wall stops too much water entering and prevents cell lysis.

What happens to a plant cell in a isotonic solution?

An isotonic solution is a solution, which contains the same concentration of solute as in a cell. If animal and plant cells are kept in isotonic solution then cells will not swell or shrink. Hence, there will not be any change in cells.

What will happen to a plant cell in a hypotonic solution?

When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become “turgid” i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.

What happens to red blood cell in isotonic solution?

When a red blood cell is placed in a hypertonic solution, it shrinks as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in ahypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell

What solution causes osmosis?

Osmotic Pressure Causes Water to Move across Membranes Or, in other words, since solutions with a high amount of dissolved solute have a lower concentration of water, water will move from a solution of high water concentration to one of lower. This process is known as osmotic flow.

Does hypertonic move in or out?

Tonicity and cells

Tonicity of solution Solute concentration Water moves…
Hypertonic Higher solute in solution than in cell Out of the cell
Isotonic Equal amounts of solute in cell and solution Into and out of cell at the same time
Hypotonic Lower solute in solution than in cell Into the cell

What does a hypertonic solution look like?

In Latin, the prefix hyper means over or above. Hypertonic solutions have a higher solute concentration than inside the cell. This is clearly seen in red blood cells undergoing a process called crenation. Plant cells in a hypertonic solution can look like a pincushion because of what’s going on inside
