Plants pt 2
What is the difference between primary and secondary growth?
Primary growth is vertical
Secondary growth is horizontal
What is translocation?
Movement of sugars
Organ, Cellular, Chemical, Body System, Tissue, Organism
Place these in order from smallest to largest
Chemical, Cellular, Tissue, Organ, Body System, Organism
What is urea?
Nitrogenous waste through your pee
Which structure of the blood vessel has the most pressure?
Arteries
Root VS shoots
Roots are the area below soil that absorb nutrients and water, stability
Shoots are the area above soil that absorbs light and carbon dioxide
How does water potential travel/flow?
High to low
What type of tissue is blood?
Connective tissue
What is the difference between hyperosmotic and hypoosmotic?
Hyperosmotic is a solution that has a higher solute concentration compared to the environment
Hypoosmotic is a solution that has a lower solute concentration compared to the environment
What is the difference between open and closed circulation?
Open circulation allows blood to freely flow in cavities
Closed circulation keeps blood in confined blood vessels
What are the 3 main plant tissue systems?
Dermal, ground, and vascular
What is the difference between source and sink?
Source is where sugar enters the phloem
Sink is where sugar exits the phloem
What type of connective tissue is fat?
Loose
What does the Bowman's capsule do?
Filters blood
What are the 5 steps of gas exchange?
Ventilation, diffusion at respiratory, circulation, diffusion at tissue, and cellular respiration
Explain the difference between phloem and xylem
Phloem conducts food in two different directions
Xylem conducts water and nutrients in one way going up w/ dead cells
What is cohesion tension theory?
Explains how water is pulled up from roots to leaves
Explain the four different types of tissues
Connective is filling that covers organs and tissues (blood and bones and cartilage)
Muscle is tissue that moves (cardiac, biceps, quad, etc...)
Nervous is neurons that communicate (nerves)
Epithelial is the thing that lines organs and covers body (skin)
The fish gains water and loses ions, loses most water through urine, are hyperosmotic, and needs to pump electrolytes
Saltwater or freshwater fish?
Freshwater fish
What are valves important?
What is the equation for water potential?
solute potential + pressure potential
What is pressure flow hypothesis?
The mechanism that sugar moves through the phloem between sources and sinks
The sensors detect, the integrators compare the control, and the effectors fix it
What part of the nephron is active transport?
Thick ascending limb
Starting w/ deoxidated blood, list the order it travels through the heart
Right atrium, right ventricle, left atrium, left ventricle, and leaves through the Aorta
