5. The model includes a wavy arrow to show light striking the thylakoids. Which label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:

d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

Explanation:

Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.

Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.

These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

Not always. For an idea to be considered scientific, it must be testable and observable.

 Theories may take many years to prove or disprove. In some cases, a theory needs extensive research before scientists have enough data to accept or reject it.

 Laws DO NOT change over time. You should know that

 Models are crucial tools in science. Without models, it would be difficult or impossible to observe, explain, and understand many parts of Earth and its various systems.

 1. Small-Scale Objects: Models are made to represent objects that are very small. This type of model makes it so the object being studied can be seen without a microscope. A model of a cell or an atom is an example.
2. Large-Scale Objects: Models are made to represent objects that are very large. This type of model makes it so the object being studied can be seen in a manageable area. An example of this type of model is a scale model of a building or of the solar system.
3. Distant or Unobservable Objects: Distant objects may be shown in models. For example, models are made to represent the locations of objects very far away in space. Sometimes, objects can never be seen. For instance, the interior of Earth may be shown as a model.
4. Maps: Maps are another type of model that scientists use. Street maps are a common type of map. Other types of maps help scientists to explore the ocean floor, study water flow, find oil deep in the ground, or study the surface of the moon.
5. Computer Models: Computer models and simulations are useful for predicting future events. Climate models run by powerful computers help scientists to understand and predict Earth's weather.
6. Equations and Graphs: Equations are models that use symbols (including letters and numbers) to represent data, processes, or events. Chemical equations are used by chemists to model chemical reactions. Equations may also be represented in graph form to show the relationships between sets of data.


 To minimize misunderstanding between scientists, measurement has a common language: the metric system.
