Hypertonic, hypotonic and isotonic

hypotonic

A hypotonic solution has less solute concentration and more solvent concentration. When a cell is placed in hypotonic solution , water enters the cell through osmosis. Animal cells swell and burst due to absence of cell wall. HYPO- CELL SWELL

hypertonic solution

A solution in which the concentration of solutes is greater than that of the cell that resides in the solution

isotonic solution

A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

example of endocytosis

An amoeba consuming food using pseudopods white blood cells engulfing debris

example of hypotonic solution

Distilled and Pure Water

How are vesicles formed?

Folding of the cell membrane

What happens to a cell placed in a hypertonic solution?

The effects of hypertonic solution in animal and plant cell. Contain higher concentration of solutes and less of water than a cell. Since the concentration of water is higher within the cell, there is a net movement of water from inside to outside of the cell. (water leaves the cell by osmosis)

Plasmolysis

This happens when a cell shrinks inside its cell wall while the cell wall remains intact.

What are the 2 type of active transport?

endocytosis and exocytosis

example of facilitated diffusion

glucose transport

example of exocytosis

hormones or wastes released from cell insulin being released from pancreas cells

what organelle produces energy

mitochondria

What does the golgi do?

packages and ships out proteins, lipids, fats, steroids (FedEX), either elsewhere in cell or to cell membrane to be exocytosed

What organelle controls hoemostasis

plasma membrane

Example of isotonic solution

red blood cells and plasma

example of hypertonic solution

salt water

Hypotonic

when comparing two solutions, the solution with the lesser concentration of solutes
