Holt Biology Chapter 01

ribosomal RNA (rRNA) – RNA molecules that construct ribosomal subunits.
Pipette – A tube-shaped, usually glass or plastic device with a tiny opening at one end used for transferring small drops of liquid (see image card).
Bacteria – "A single-celled, microscopic prokaryotic organism"
Phenomena – A fancy word for "events" or simply "something that happens" in the world. Examples: Hurricanes. Migration. Etc.
light-independent reactions – These are chemical reactions that convert carbon-dioxide to glucose (organic moles)
fruiting body – A multicellular structure which holds spore producing structures.
thyroxine – A hormone produced by the thyroid gland.
In the above picture, structure #16 is:
Feedbacks – Mechanisms that controls Homeostasis
Function of the Plasma Membrane – 1.Protects the cell.
2.Separates the intracellular components from the extracellular environment.
3.Controls what enters and exits the cell
cell enlargement – the increase in cell size examples
Ex: muscle cells will increase in size as they are used
aquaporin – A membrane protein, specifically a transport protein, that facilitates the passage of water through channel proteins.
Golgi apparatus – stack of membranes that modifies, sorts, and packages proteins from the endoplasmic reticulum
monosacchride – single sugar molecule
In the аbоve picture, structure #16 is:
Termination Signal – Marks the end of a gene.
solute – A substance that is dissolved in a solution.
Permeable – Allowing substances to pass or diffuse through. Pores are the widest and it is not very selective.
