M1L1-Photosynthesis and Cellular respiration

What does the cuticle of a leaf do?

• Allows gas exchange

• Captures light

• Provides a waxy protective layer

• Contains chlorophyll

Which of the following statements about the epidermis is correct?

• It is where photosynthesis occurs.

• It contains chloroplasts.

• It is flat and located at the top and bottom of the leaf.

• It allows gas movement.

Where are stomata mostly found on a leaf?

• On the top surface

• On the bottom surface

• Throughout the leaf

• Only near the veins

Which of the following statements best describes the main difference between photosynthesis and cellular respiration?

• Photosynthesis releases energy, while cellular respiration stores energy.

• Photosynthesis produces oxygen and glucose, while cellular respiration breaks down glucose to release energy.

• Both photosynthesis and cellular respiration occur only in plants.

• Photosynthesis requires oxygen, while cellular respiration requires carbon dioxide.

Which of the following is true about photosynthesis?

• It only occurs in animals to release energy.

• It requires carbon dioxide and water as reactants and produces oxygen and glucose.

• It breaks down glucose to release energy.

• It uses oxygen and glucose to produce carbon dioxide and water.

What is the primary source of energy for photosynthesis?

• Water

• Carbon dioxide

• Light energy

• Chemical energy

Which of the following is the correct equation for photosynthesis?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Sunlight

• 6CO2 + 6H2O + sunlight → C6H12O6 + 6O2

• 6H2O + 6O2 + sunlight → C6H12O6 + 6CO2

• C6H12O6 + 6CO2 → 12H2O + 6O2

The diagram shows how matter moves in a tree. Which statement describes one way that the source of the energy released during cellular respiration is delivered to tree cells?

• Water is transported from the roots to the leaves.

• Sugars are transported from the leaves to the roots.

• Minerals are transported from the roots to the leaves.

• Carbon dioxide is transported from the leaves to the roots.

Which of the following is NOT correct?

• The sun is the main source of energy for most life on Earth

• Not all energy an organism gets is used for life processes, some is released as thermal energy

• Energy cannot be created, but it can change form. This is called law of conservation of energy

• Energy is like matter, it cycles through ecosystems, instead of flowing in one direction

Mahra is drawing a model of what happens when a person eats an apple. Which statement best describes the next step in Mahra's model?

• Sugar molecules break down further to release energy inside of cells.

• Sugar molecules combine chemically to absorb energy made by cells.

• Sugar molecules break down further to release oxygen for use by cells.

• Sugar molecules combine with other molecules to absorb waste material from cells.
