Osmosis
The Diffusion Of Water Molecules Across A Selectively Permeable Barrier Such As The Cell Membrane From A Region Of Lower Solute Concentration To Higher Solute Concentration.

Diffusion
The Passive Movement Of Particles From An Area Of Higher Concentration To An Area Of Lower Concentration, Often Across The Cell Membrane.

ATP
Adenosine Triphosphate, A Molecule That Stores And Transfers Energy Within Cells And Is Produced During Cellular Respiration And Photosynthesis.

Cellular Respiration
A Series Of Metabolic Reactions In Which Organic Molecules Such As Glucose Are Broken Down To Produce Atp, Mainly In The Mitochondrion.

Photosynthesis
A Process In Which Plants, Algae, And Some Bacteria Use Light Energy To Convert Carbon Dioxide And Water Into Glucose And Oxygen Inside The Chloroplast.

Chloroplast
A Green Organelle Found In Plant And Algal Cells That Carries Out Photosynthesis Using Pigments Such As Chlorophyll To Capture Light Energy.

Mitochondrion
An Organelle In Eukaryotic Cells That Produces Most Of The Cell Atp Through Cellular Respiration And Is Often Called The Powerhouse Of The Cell.

Ribosome
A Molecular Machine Found In The Cytoplasm And On The Rough Endoplasmic Reticulum That Uses Rna To Assemble Amino Acids Into Proteins During Translation.

Enzyme
A Type Of Protein That Speeds Up Chemical Reactions In The Cell By Lowering The Activation Energy Without Being Consumed In The Process.

Amino Acid
A Small Organic Molecule That Serves As A Building Block Of Proteins And Contains Both An Amino Group And A Carboxyl Group.
