The (1._____) cells of the leaf have chlorophyll. In order to photosynthesize, they need light and (2._____), which they get from the atmosphere. This molecule, however, needs to be dissolved in water, so the cells are wet. This moisture is subject to evaporation and transpiration through the (3._____), which can be closed during water stress by the (4._____ _____). Thus, there is a tradeoff between productivity and water conservation.

......Use the following to feel out the sentense: cycled, photosynthesis, cellular respiration, oxygen, carbon dioxide, ATP

During ____________ , mitochondria break down carbohydrates to produce energy that is used to make ____________ .

This process requires ____________ and carbohydrates, and produces ____________ and water.

During ____________ , chloroplasts use water and ____________ to create carbohydrates.

This process requires ____________ and water, which are byproducts from ____________ .

In turn, it produces ____________ and carbohydrates that are used in ____________ .

In this manner, the flow of energy is ____________ between chloroplasts and mitochondria.

..........use the following to feel out each sentense: from, oxidized, photosynthesis, cellular respiration, gains, to, loses, reduced.

During ____________ , hydrogen atoms are transferred ____________ water ____________ carbon dioxide as glucose forms.

Thus, during ____________ , carbon dioxide is ____________ , while water is ____________ . In other words, carbon dioxide ____________ electrons and water ____________ electrons.

During ____________ , glucose is ____________ as oxygen is ____________ , becoming water.

In each of these reactions, while one molecule loses electrons (is ____________ ), another gains electrons (is ____________ ); thus, each of these metabolic pathways includes redox reactions: coupled reduction and oxidation reactions.

..........use the following to feel out the sentenses: increase, conservation of energy, first of thermodynamics, input, decrease, laws of thermodynamics, secod law of thermodynamics, heat

The ____________ explain energy flow and energy conservation and can be applied to biological systems.

The ____________ states that energy cannot be created or destroyed, also known as the law of ____________ .

The ____________ states that energy is lost when it is converted from one form to another, often in the form of ____________ .

As cells go through transformations, they ____________ the total entropy of the universe, resulting in a ____________ in available energy.

For example, photosynthesis in plants requires an energy ____________ to turn carbon dioxide and water into sugar because there is a ____________ in entropy.

Question 1


Which of the following provides the best description of adifference between prokaryotic and eukaryotic cells?.l.14.3>

The cell membrane of prokaryotic cells contains proteins, whilethe cell membrane of eukaryotic cells contains only lipids andcarbohydrates.

The DNA in eukaryotic cells is enclosed in the nucleus, whilethe DNA in prokaryotic cells is not separated from the rest of thecell’s contents.

Eukaryotic cells have cell walls that consist mainly of sugars,while prokaryotic cells do not.

Prokaryotic cells contain chloroplasts and mitochondria, whileeukaryotic cells do not contain specialized organelles.

Question 2

Cellular respiration is a process involving the breakdown ofglucose molecules in order to generate energy for cellularactivities. Given the general reaction below, which of thefollowing best describes the products labeled x andy?

C6H12O6 + O2 → _x___+ __y___ + energy.l.18.8>

The products are CO (carbon monoxide) andH2O2 (hydrogen peroxide), which thendecompose into carbon dioxide (CO2) and water(H2O).

The products are H2O (water) and CO2 (carbondioxide), which then undergo anaerobic respiration.

The products are CO2 (carbon dioxide) andH2O (water), which then become the reactants forphotosynthesis.

The products are O2 (oxygen) and H2O(water), which are then used for growth and to keep the organismhydrated.
