Place these in order of increasing complexity: cells, cell organelles, organs, organ systems, tissues

Increasing Complexity Cell Organelles Cells Tissues Organs Organ Systems Increasing Complexity

1 - The site of protein synthesis Daily Double!!! 1 - The site of protein synthesis 2 - Stores the information for protein synthesis

1 – ribosome 2 - nucleus

Endoplasmic Reticulum Functions of the Endoplasmic Reticulum and the Golgi Apparatus

Transporting Proteins (ER) Packaging Proteins (Golgi) 3

Two organelles most directly involved in cellular respiration

cell membrane and Mitochondria

4 organelles directly involved in protein synthesis – place them in the order of their involvement

Nucleus Ribosome Endoplasmic Reticulum Golgi Apparatus

Indicator for starch and positive result Indicator for glucose and positive result

Starch indicator = iodine + result = purple/black color Glucose indicator = Benedict’s solution + result = orange/red color when heated

What are the 3 substances that could pass through the cell membrane? What substance could not pass through the cell membrane? How do we know? Show the location of these substances on the diagram below

Glucose, Iodine, and water Starch inside turned blue, outside did not

Name the organelle Explain it’s function and the kind of transport it accomplishes Describe the tonicity of the environment in which the cell must synthesize it Describe the tonicity of the environment in which the cell does not need it

Contractile vacuole Pumps out water (active transport) that is entering (flooding) a cell by osmosis because the cell is in a hypotonic environment The cell does not need it in an isotonic (or hypertonic) environment

Explain how someone can die from drinking too much water

Their red blood cells go boom! OSMOSIS Their red blood cells go boom!

What happened to these cells What happened to these cells? What kind of solution (tonicity) were they placed in?

They were placed in a hypertonic solution (e. g They were placed in a hypertonic solution (e.g. salt solution) and water left the cells by osmosis (Higher Water concentration)

What characteristic of the cell membrane is illustrated here? Daily Double!!! What characteristic of the cell membrane is illustrated here?

Selective Permeability

Four life processes associated with the cell membrane

Regulation Nutrition Transport Excretion

Describe one similarity passive and active transport. and one difference between passive and active transport.

Both processes move substances across the cell membrane Active transport requires energy (ATP) Passive Transport does not require energy

functions of four different proteins in the cell membrane

ID proteins Receptors Transmembrane proteins - channel proteins facilitated diffusion) - pump proteins

D C E A B
