How do you find the sample size of an experiment
Number of samples given per group X the group size
How do you find the average in a set of data
add your results and divided by the group’s
How do you find your median
List numbers from lowest to highest encircle the middle number that is a median
How do you find your range
Look at your from lowest to highest. Subtract the lowest number from the highest number your result is your answer
How do you find your mode
From lowest to highest the number that repeats the most
To show the distribution of results of a graph
You match the percentage with the number of times he repeated itself
Polar molecules vs nonpolar molecules
- Polar molecules are charged molecules that are hydrophilic
- Nonpolar molecules have no charge and are hydrophobic
Cell wall structure
The plant cell wall is multi-layered and consists of up to three sections. From the outermost layer of the cell wall, these layers are identified as the middle lamella, primary cell wall, and secondary cell wall.
What are the reactants in overall equation of photosynthesis
6 CO2 + 6 H2O Arrow sunlight energy C6 h12 o6 + 602
The plant utilizes six carbon monoxides 6 Waters and converts it into glucose and 6 molecular oxygen
What two lights are most effective in photosynthesis
Red and blue
Name the three stages of photosynthesis
(1) absorption of light,
(2) electron transport leading to the reduction of NADP+to NADPH,
(3) generation of ATP, by the conversion of CO2into carbohydrates (carbon fixation)
What is the main pigment of photosynthesis
Chlorophyll
What color is chlorophyll
Green
Why is the amount of starch produced by leave considered a good measure of the amount of photosynthesis that the leaf carried out
Starchis a polymer made byplantstostoreenergy. … They use energy from sunlight to make a simple sugar, glucose.Plantsmake polymers -starch- out of extra glucose, so it’s right there when they need it.
What is the rigid structure seen on the outside of the cell through a microscope
Cell wall
What are the extensions on the amoeba called
Pseudopodia
Around dark structure seen in the middle of the amoeba
Nucleus
When a membrane selects certain molecules to pass what type of membrane is this
Selectively permeable
A passive process that requires no energy
Diffusion
When looking at a potato under a microscope certain oval shaped structures were seeing that stain blue black or purple with iodine name those structures
Leucoplasts
What is the function of leucoplasts
bulk storage ofstarch,lipidorprotein
What is chloroplast
This site where energy from light is used to make sugar
What is the cytoskeleton
Internal set of filaments fibers and microtubules made of protein that give the cell its shape and allows for internal and external shell cells get shorter and longer depending on the muscle or part of the body
