Lab Chapters 1-6

Question 1

How do you find the sample size of an experiment

Answer 1

Number of samples given per group X the group size

Question 2

How do you find the average in a set of data

Answer 2

add your results and divided by the group’s

Question 3

How do you find your median

Answer 3

List numbers from lowest to highest encircle the middle number that is a median

Question 4

How do you find your range

Answer 4

Look at your from lowest to highest. Subtract the lowest number from the highest number your result is your answer

Question 5

How do you find your mode

Answer 5

From lowest to highest the number that repeats the most

Question 6

To show the distribution of results of a graph

Answer 6

You match the percentage with the number of times he repeated itself

Question 7

Polar molecules vs nonpolar molecules

Answer 7

1. Polar molecules are charged molecules that are hydrophilic
2. Nonpolar molecules have no charge and are hydrophobic

Question 8

Cell wall structure

Answer 8

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.

Question 9

What are the reactants in overall equation of photosynthesis

Answer 9

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

Question 10

What two lights are most effective in photosynthesis

Answer 10

Red and blue

Question 11

Name the three stages of photosynthesis

Answer 11

(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)

Question 12

What is the main pigment of photosynthesis

Answer 12

Chlorophyll

Question 13

What color is chlorophyll

Answer 13

Green

Question 14

Why is the amount of starch produced by leave considered a good measure of the amount of photosynthesis that the leaf carried out

Answer 14

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.

Question 15

What is the rigid structure seen on the outside of the cell through a microscope

Answer 15

Cell wall

Question 16

What are the extensions on the amoeba called

Answer 16

Pseudopodia

Question 17

Around dark structure seen in the middle of the amoeba

Answer 17

Nucleus

Question 18

When a membrane selects certain molecules to pass what type of membrane is this

Answer 18

Selectively permeable

Question 19

A passive process that requires no energy

Answer 19

Diffusion

Question 20

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

Answer 20

Leucoplasts

Question 21

What is the function of leucoplasts

Answer 21

bulk storage ofstarch,lipidorprotein

Question 22

What is chloroplast

Answer 22

This site where energy from light is used to make sugar

Question 23

What is the cytoskeleton

Answer 23

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
