NGSS.MS-LS1-1

NGSS.MS-LS1-2

NGSS.MS-LS1-3

Microscopic, unicellular organism without a nucleus or other membrane-bound organelles.

• Prokaryotic Cell

• Eukaryotic Cell

Property of the plasma membrane that allows it to control movement of substances into or out of the cell.

• Phospholipid Bilayer

• Fluid Mosaic Model

• Selectively Permeable

• Diffusion

Plasma membrane layers composed of phospholipid molecules arranged with polar heads facing the outside and nonpolar tails facing the inside.

• Diffusion

• Phospholipid Bilayer

• Fluid Mosaic Model

• Selective Permeability

Net movement of particles from an area of higher concentration to an area of lower concentration

• Exocytosis

• Endocytosis

• Osmosis

• Diffusion

Semifluid material inside the cell's plasma membrane.

• Cytoplasm

• Cytoskeleton

• Centriole

• Cell Wall

NGSS.MS-LS1-2

Vesicle that uses enzymes to digest excess or worn-out cellular substances.

• Ribosome

• Nucleolus

• Vacuole

• Lysosome

Tags

NGSS.MS-LS1-7

Supporting network of protien fibers that provide a framework for the cell within the cytoplasm.

• Centriole

• Cytoskeleton

• Mitochondrion

• Cell Wall

Membrane-bound vesicle for temporary storage of materials such as food, enzymes, and wastes.

• Vacuole

• Ribosome

• Golgi Apparatus

• Cilium

A solution that has a lower concentration of solute outside than inside the cell, causing water to flow into the cell by osmosis.

• Osmosis

• Isotonic Solution

• Hypertonic Solution

• Hypotonic Solution
