Q2 Quarterly review

Question 1

In simple terms, how does photosynthesis work?

Answer 1

The plant takes in light energy to make food. (Sugar)

Question 2

Where does photosynthesis occur?

Answer 2

In the chloroplasts.

Question 3

What in a chloroplast absorbs sunlight?

Answer 3

Chlorophyll

Question 4

What are the reactants of photosynthesis?

Answer 4

CO2, Water, Sunlight

Question 5

What are the products of photosynthesis?

Answer 5

Oxygen, Glucose

Question 6

What is the formula for glucose?

Answer 6

C₆H₁₂O₆

Question 7

Why are plants typically green?

Answer 7

Green light is reflected and blue, red and white light is absorbed

Question 8

What does the Law of Conservation of Mass say?

Answer 8

Matter cannot be created or destroyed.

Question 9

What is glucose converted into during cellular respiration?

Answer 9

ATP

Question 10

What is the chemical equation for cellular respiration?

Answer 10

C6H12O6 + 6O2 —-> ATP + 6CO2 + H2O

Question 11

What are the 3 stages of cellular respiration?

Answer 11

Glycolysis, Krebs Cycle, Electron Transport Chain

Question 12

Where does glycolysis take place, what does it do, and what is the result?

Answer 12

Takes place in the cytoplasm, breaks down glucose into 2 pieces which moves to the Krebs cycle, and results into 2 ATP, electrons and broken down glucose.

Question 13

Where does the Krebs Cycle take place, what does it do, and what is the result?

Answer 13

Takes place in the mitochondria, The rest of the glucose is broken down and electrons go to the Electron Transport Chain, and the result is 2 ATP, electrons and CO2.

Question 14

Where does the Electron Transport Chain take place, what does it do, and what is the result?

Answer 14

Takes place in the mitochondria, energy is transferred to a chain of proteins in the inner membranes of the mitochondria, and the result is 32-34 ATP and H2O.

Question 15

In simple terms, what is the Carbon Cycle?

Answer 15

The movement of carbon from one area to another.

Question 16

What are some examples of how carbon is found in the atmosphere?

Answer 16

Nature can put carbon in the atmosphere through diffusion from the ocean floor and volcanic activity. Humans can put carbon into the atmosphere through deforestation, burning wood, and burning fossil fuels.

Question 17

How is carbon found in the lithosphere?

Answer 17

Carbon is in the form of carbonate rocks in the lithosphere.

Question 18

How is carbon found in the biosphere?

Answer 18

Carbon is found and stored in plants and in trees. That carbon is used for the building blocks of photosynthesis.

Question 19

How is carbon found in the hydrosphere?

Answer 19

Carbon is found dissolved in bodies of water such as oceans or lakes. It can be used to produce shells and photosynthesis for marine plants.

Question 20

What is the biggest absorber of CO2?

Answer 20

The ocean

Question 21

What is the 10% rule?

Answer 21

As you move up the pyramid, 10% of the energy is obtained from each level.

Question 22

What is parasitism and one example?

Answer 22

One benefits and the other is harmed. An Examples include tapeworms or ticks.

Question 23

What is mutualism and 1 example?

Answer 23

Both organisms benefit. For example, shrimps and crabs live and capture food within the tentacles of a giant anemone.

Question 24

What is commensalism and 1 example?

Answer 24

One benefits and the other has no effect. An example would be the pearl fish live in sea cucumbers intestines for shelter, but the sea cucumber itself is not affected.

Question 25

What are the advantages of group behavior?

Answer 25

It is harder for predators to hunt a single animal in a group.

Question 26

What are the disadvantages of group behavior?

Answer 26

There can be increased competition for mating or food.

Question 27

What are the disadvantages of a swarm, flock, a school, or herd?

Answer 27

Disease can spread faster in a group.

Question 28

What is migration and why do organisms migrate?

Answer 28

Migration is moving from one place to another for things like seasonal changes. Some animals may migrate for things such as breeding.

Question 29

What are factors that can limit the number of plants/trees in an area?

Answer 29

Not enough room for things like growing roots, plants blocking sunlight for other plants, not enough water, etc.

Question 30

What are the factors that limit the number of animals in an area?

Answer 30

Not enough food, water and/or space.
