Q2 Week 5 Review Quizizz

What is the source of energy for photosynthesis?

• Carbohydrates (chemical energy)

• Light (radiant energy)

• Heat (thermal energy)

• Wind (kinetic energy)

Answer explanation

The source of energy for photosynthesis is light (radiant energy). Plants capture sunlight to convert carbon dioxide and water into glucose and oxygen, making light essential for this process.

What are the 3 key ingredients needed for photosynthesis

• glucose, oxygen, carbon dioxide

• carbon dioxide, water, glucose

• water, soil, sunlight

• sunlight, water, carbon dioxide

Answer explanation

Photosynthesis requires sunlight, water, and carbon dioxide. Sunlight provides the energy, water is absorbed by plants, and carbon dioxide is taken from the air. These three ingredients are essential for producing glucose and oxygen.

Which of the following examples go through the process of photosynthesis?

• bees

• algae

• humans

• mushrooms

Answer explanation

Algae are photosynthetic organisms that convert sunlight into energy, using carbon dioxide and water. Unlike bees, humans, and mushrooms, which do not perform photosynthesis, algae play a crucial role in producing oxygen and organic matter.

What is the name of the sugars a plant produces after photosynthesis

• Glucose

• Sugar

• ATP

• Oxygen

Answer explanation

The correct answer is Glucose, as it is the primary sugar produced by plants during photosynthesis. While 'Sugar' is a general term, Glucose specifically refers to the type of sugar synthesized in this process.

________ is the process that plants use to make their own food.

• hibernation

• migration

• photosynthesis

• transpiration

Answer explanation

Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen, allowing them to produce their own food. Hibernation and migration are animal behaviors, while transpiration involves water movement.

What are the products (comes out) of photosynthesis.

• sugar

• sunlight

• water

• oxygen

Answer explanation

Photosynthesis produces sugar and oxygen as its main products. Plants convert sunlight, carbon dioxide, and water into glucose (sugar) and release oxygen as a byproduct.

Organisms that create their own energy from sunlight or chemicals

• Herbivore

• Omnivore

• Autotroph

• Heterotroph 

Answer explanation

Autotrophs are organisms that produce their own energy through photosynthesis or chemosynthesis, unlike herbivores and omnivores that consume other organisms for energy. Therefore, the correct answer is Autotroph.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar

• CO₂ + sugar + H₂O --> O₂ + light

• _O2 + light + H₂O --> CO₂ + Sugar

• CO₂ + O₂ + H₂O --> Light+ Sugar

Answer explanation

The correct equation for photosynthesis is CO2 + light + H2O -> O2 + Sugar. This process occurs in plants, converting carbon dioxide and water into glucose and oxygen using sunlight.

A process in which substances chemically rearrange to form new substances

• chemical reaction

• breathing

• glucose

• mitochondria

Answer explanation

A chemical reaction is a process where substances undergo a transformation, rearranging their atoms to create new substances. This definition directly matches the question, making 'chemical reaction' the correct choice.

Change cannot occur without it

• energy

• matter

• glucose

• oxygen

Answer explanation

Energy is essential for change to occur, as it drives processes in both physical and biological systems. Without energy, matter cannot transform or move, making it the correct answer.
