Organelles

100

Provide the function of this organelle:

nucleus

command center, produces DNA and instructions for cell activity

200

Provide the function of this organelle:

Endoplasmic reticulum

produces proteins and carries throughout cell

300

Provide the function of this organelle:

Vacuole

stores fluids and nutrients in plant cells

400

Provide the function of this organelle:

Cell wall

provides structure and protects plant cells

500

Provide the function of this organelle:

lysosome

breaks down toxins and unwanted materials in the cell

Biomes

100

Explain the precipitation level (low med or high) and physical characteristics of the following biome:

Desert

low, dry sandy little vegetation

200

Explain the precipitation level (low med or high) and physical characteristics of the following biome:

Grassland

med, grasses, small shrubs, few trees

300

Explain the precipitation level (low med or high) and physical characteristics of the following biome:

Deciduous Forest

high, lots of trees that lose their leaves

400

Explain the precipitation level (low med or high) and physical characteristics of the following biome:

tropical rain forest

high, lost of trees, flowers, plants of all kinds

500

Explain the precipitation level (low med or high) and physical characteristics of the following biome:

Tundra

low, scattered small vegetation

Meiosis/Mitosis

100

List 3 reasons mitosis occurs

growth, repair, replacement

200

explain the difference in the terms diploid and haploud

diploid cells has 2 sets of chromosomes one from mom and one from dad, haploid only have one set

300

Meiosis involves a total of ______ phases, excluding cytokinesis

9: I PMAT(I), PMAT(II)

400

Explain what happens during interphase

G1 - replication of all organelles except for chromosomes, S - replication of chromosomes, G2 - check for any errors

500

If a germ cell starts with a total of 40 chromosomes, how many cells would be produced and how chromosomes would each have after  meiosis

4 cells, 20 chromosomes each

Photosynthesis/Cellular Res.

100

Name the reactants involved in cellular respiration

glucose and oxygen

200

What is the job of atp synthase in photosynthesis and how does it work?

it makes ATP from ADP and P, it is powered by the movement on H+ through the protein 

300

Name the final step of cellular respiration AND many ATP are produced in this step

electron transport chain, 32 ATP

400

Explain why lactic acid would be produced during cellular respiration and during which step

if there is a lack of oxygen due to exertion of energy then lactic acid is produced during anerobic glycolysis

500

compare and contrast cellular respiration and photosynthesis with  3 similarities and 3 differences

answers will vary

Macromolecules

100

Name the 4 major macromolecules

protein, nucleic acids, carbs, lipids

200

Explain what hydrolysis is and why it happens

it is the addition of H2O to a macromolecule it happens when larger molecules need to be broken into smaller ones

300

Fatty acids are monomers of __________ and they are made up of ___________.

lipids, glycerol and hydrocarbon chain

400

Name the basic components of a nucleic acid monomer

nucleotide - sugar (ribose or deoxyribose, phosphate group, nitrogenous base

500

The monomers of proteins are called __________, and the monomers of carbohydrates are called _____________.

peptides/ amino acids, monosaccharides
