  • Front
  • Back

Means having a charge (think phospholipid Head)

Polar w

Water moves into the cell at same rate as it goes out

Isotonic

Another name for the cell membrane

Plasma membrane

Means more strength

Hypertonic

The storage form of energy

ATP

Found in large amounts in a solution

Solvent

An active process by which cells realease wastes or products

Exocytosis

The parts of the phosphoild that are hydrophobic

Tails

Cells eating

Phagocytosis

Cells drinking

Pinocytosis

Releasing things out of a cell like wastes and products ( atp needed)

Exocytosis

These are usually large substances and are brought in by

Vesicles

Active transport pushes a molecule/ moles-clues against a

Concentration gradient

Facilated diffusion requiring

Carrier

The membrane is flexible

Not rigid

An art term used to describe a painting made of bits of glass or other objects

Mosaic

Molecules are shaped like a head with two tail

Phospholipids moleclues

He head is polar and forms hydrogens bonds with water

Hydrophilic

The fatty acid tail is

Nonpolar

Gycerol alchol

( also part of head)

Two fatty acid chains

Two tails

Strengths the cell membrane and helps it stay flexible

Cholesterols

ID badges do cells can tell one type of cell from another

Carbohydrates

A cell cannot function without things entering and exiting through the cell membrane

Selective permeability

Movement of molecules from high concentrations to low concentrations

Diffusion

Requires energy input (ATP) like playing a roll bridge

Active transport

No energy required (ATP) like rolling down hill

Passive transport

Difference of concentration of a moleclue in a cell or area

Concentration gradient

A special type of diffusion where water moves through the cell membrane

Osmosis

When the number of molecules on one side of the same number on the other side

Bynamic equilibruim

Atp

=energy

Solution

:solute+solvent=soultion

Is a mixture of two or more substances

Solution

3 types of solutions

Isotonic , hypertonic, hypotonic

ISO=

SAME

Is a mixture of two or more substances

Solution

ISO=

SAME

Hyper

=more

3 types of solutions

Isotonic , hypertonic, hypotonic

ISO=

SAME

Hyper

=more

Hypo

=less

A cell in a hypotonic water moves into the cell

( cell swell and likely burst).

Type of transport that does not require ATP

Passive

Means water loving

Hydrophilic

Two or more substances

Solution

Cell membrane are constructed mainly of

Phospholipid bilayers

Cell membrane are constructed mainly of

Phospholipid bilayers

It controls which substances enter and exit the cell

Cell membrane

The function of carbohydrates in the cell membrane

Communication

The function of proteins in cell membrane

Cellular transport

Stores energy for the cell in from of sugar

Photosynthesis

The process releases energy stored in sugar

Cellular respiration

This energy-rich molecule, produced by cellular respiration, is vital for the functioning of the cell is

ATP

In hypertonic solutions were moves_____the cell

Out of

Hypertonic solution will cause animals cells to

SHRINK

The process of the cell contents completely shrinking away from the cell wall is

Plasmolysis

In an isotonic soultion , equal amounts of water are moved INSIDE and OUTSIDE cell .

^^

When this happen the cel is in dynamic EQUILIBRIUM which means the waiter is still moving but is moving in equal amounts

^^

While an animal cell will stay the same a plant cell may not have enough water to fully fill the cell cavity. so plant cell may appear

WILTED OR FLACCID (limp)

In an isotonic soultion , equal amounts of water are moved INSIDE and OUTSIDE cell .

^^

When this happen the cel is in dynamic EQUILIBRIUM which means the waiter is still moving but is moving in equal amounts

^^

While an animal cell will stay the same a plant cell may not have enough water to fully fill the cell cavity. so plant cell may appear

WILTED OR FLACCID (limp)

In HYPOTONIC SOLUTION water moves into the cell .

^^

Animals cells will SWELL if the cell membrane is not strong enough it may BURST

^^

Animals cells will SWELL if the cell membrane is not strong enough it may BURST

^^

Cells walls allow pressure to build up in

PLANT CELLS

The pressure caused by water moving in to a plant cell called

Turgur pressure

Hypotonic

Have more inside then outside

Hypotonic

Have more inside then outside

Isotonic

Have the same amount inside and outside .

Hypertonic

Have way more outside then inside !
