1 Semester Review Identify the cause of molecular movement Identify the three factors that are required for there to be competition Passive transport mechanisms always move molecules in what direction along a gradient? Identify the cause to a slowed population growth rate if immigration and emigration remain equal? 1

2 Nucleus Identify the first level of any food chain or food web Identify the percent of energy that is passed from one trophic level to another, on average Describe the population that should result in years Assembly of ribosomes begins here Cytoplasm 2

3 Identify at least two functions that use energy from ATP Identify the four cell structures that all types of cells have. An animal cell with an internal salt concentration of 0.3% is placed in a salt solution with a concentration of 1.0%. Identify the type of solution the cell was placed in & explain what will happen to the cell (use appropriate terms). Identify the three products that result from completion of the lightindependent reaction. Explain why the cell membrane is considered semipermeable Identify the eight major taxonomic ranks from most inclusive to most specific 3

4 Separates nucleus from cytoplasm Contains pores to move material in & out Contrast passive & active transport Illustrate the difference between logistic and exponential growth Identify the six types of consumer discussed in class Identify the type of population growth the human population current trending toward Chromatin 4

5 Contains DNA Identify the two reasons why photosynthesis is necessary Identify at least three densitydependent limiting factors Identify at least two ways that molecular active transport differs from any passive transport mechanism 5

ways humans alter the populations within an ecosystem

6 Provide at least two examples of types of organisms that are producers Cell Wall Identify at least three ways humans alter the populations within an ecosystem Break down and recycle macromolecules and old organelles 6

Identify the symbiotic relationship where both organisms are helped

7 Identify the three products that result from completion of the lightdependent reaction. Identify the symbiotic relationship where both organisms are helped Provide at least two reasons why some molecules are unable to cross the membrane Identify the three key nutrient cycles studied in class 7

8 Describe the role of ATP for organisms Lysosome Identify the six levels of ecological organization from smallest to largest Identify from where organisms obtain energy to form ATP Describe how the movement of energy and matter differs within a living system Identify why ions are unable to pass across a membrane by diffusion 8

9 Convert solar energy into chemical energy stored in food Contrast the sizes of prokaryotic cells, eukaryotic cells, and viruses. Chloroplast Vacuole 9

10 Predator is to prey as herbivore is to Identify the kingdoms that are able to perform photosynthesis Identify when photosynthesis occurs in the cell and why. Regulates material entering & leaving the cell Protects and supports Nuclear Membrane 10

11 Synthesize proteins Cytoskeleton Identify the six elements that are the building blocks for the four types of macromolecules. As the concentration of solute in a solution increases, what happens to the water concentration in that same solution? Define an ecological footprint Identify the two ways a population may grow in size 11

12 Cell Membrane Mitochondria Write out the complete, balanced chemical equation for photosynthesis. Identify at least two ways organisms maintain homeostasis Briefly explain what would occur to the cells of a freshwater plant that was exposed to flooding from a nearby body of salt water Briefly explain why our current model is named the fluid mosaic model 12

13 Endoplasmic Reticulum Identify at least two factors from class that affect climate Golgi Apparatus Cells placed in hypotonic solutions will always have what happen to their mass? Centriole Ribosome 13

14 Describe what happens to the concentration of a chemical, such as DDT, when it moves up a food chain. What is this concept called? Contrast endocytosis & exocytosis Contrast homeostasis in unicellular and multicellular organisms Organizes cell division 14

15 Identify the three key nutrients that often act as limiting factors within an ecosystem Vesicles Identify the two ways a population may decrease in size Illustrate a food chain that shows a tertiary consumer Define carrying capacity Identify at least two densityindependent limiting factors 15

16 Contrast phagocytosis & pinocytosis Describe how ATP functions Identify the four types of macromolecules found within all organisms. 16

17 Contrast diffusion and facilitated diffusion Shapes, supports, and protects the cell Identify the four components that make up the cell membrane Complex of DNA and proteins Briefly describe why succession happens within an ecosystem Nucleolus 17

18 Stores & moves materials around the cell In order from simplest to most complex, identify the four levels of organization within an organism. Provide an example for each level. Identify where in the cell photosynthesis occurs. Specify between the lightdependent and light-independent reactions. Illustrate a portion of a lipid bilayer including phospholipids and a protein (along with a carbohydrate receptor and cholesterol) Identify at least three things that organisms may compete over 18

19 Identify the two sources autotrophs may capture energy from Maintains cell shape Moves cell parts Helps cells move Assembles proteins and lipids Convert chemical energy in food to usable compounds Identify the primary pigment that absorbs light energy. What colors are absorbed best? What colors are absorbed poorly? Rare (not shown) 19

20 Illustrate a molecule of ATP Label each of the three components Identify the symbiotic relationship where one organism is helped while the other is neither helped nor harmed Fluid portion outside the nucleus Contrast primary & secondary succession A hypotonic solution differs from the inside of a cell in what way? Briefly describe how increased greenhouse gases lead to rising temperatures 20

21 Modifies, sorts, packages proteins and lipids for storage and transportation out of cell Contrast weather & climate Identify the reactants of photosynthesis Define homeostasis Contrast a habitat from a niche Two eggs are placed into different solutions. An egg placed into a green solution loses 2.1% of its mass, while the egg placed into a red solution loses 3.5% of its mass. Which solution has a higher solute concentration? 21
