Photosynthesis: Making Energy Final Exam with correct answers Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Chloroplasts contain the pigment, chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum, and reflects only green and yellow wavelengths of light. This is why we see leaves as green or yellow – because these colors are reflected into our eyes.

with correct answers
Chloroplasts
Photosynthesis is a process in which sunlight energy is used to make glucose. The
site of photosynthesis is in the chloroplast – an organelle found in the leaves of
green plants. The main functions of chloroplasts are to produce food (glucose)
during photosynthesis, and to store food energy. Chloroplasts contain the pigment,
chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum, and
reflects only green and yellow wavelengths of light. This is why we see leaves as
green or yellow – because these colors are reflected into our eyes.
1. What is photosynthesis? A process in which sunlight is converted
into glucose.
2. Where does photosynthesis occur? Photosynthesis occurs in the chloroplast.
3. What are chloroplasts and where are they found? An organelle found in the leaves of green
plants.
4. What are the two main functions of chloroplasts? The two functions of a chloroplast are
to produce glucose and store food energy.
5. Why do most leaves appear green? The pigment chlorophyll absorbs red and blue wavelengths
of light and reflects back green and yellow wavelengths of light.
6. What is the primary pigment found in the chloroplast? Chlorophyll is the primary pigment found
in chloroplasts.
Photosynthesis
Glucose is another name for sugar. The molecular formula for glucose is C6H12O6. Plants make sugar by
using the energy from sunlight to transform CO2 from the air with water from the ground into glucose.
This process, called photosynthesis occurs in the chloroplast of the plant cell. During this process,
oxygen (O2) is created as a waste product and is released into the air for us to breath. The formula for
photosynthesis is:
(reactants) (products)
CO2 + H2O + sunlight ----> C6H12O6 + O2
This formula says that carbon dioxide + water molecules are combined with the energy from sunlight to
produce sugar and oxygen. The reactants in photosynthesis (what is used) are CO2, water and sun. The
plant gets water from the ground through its roots. The plant collects carbon dioxide from the air.
Much of the carbon dioxide comes from living organisms that exhale (breath it out) it, but some also
comes from factory smokestacks and car fumes.
7. What is the formula for photosynthesis? CO2 + H2O + sunlight ----> C6H12O6 + O2
8. What three things are used to make glucose in photosynthesis? Carbon Dioxide, water
and sunlight are three things that are used to make glucose in photosynthesis.

Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food ( glucose ) during photosynthesis , and to store food energy. Chloroplasts contain the pigment, chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum, and reflects only green and yellow wavelengths of light. This is why we see leaves as green or yellow – because these colors are reflected into our eyes.

  6. What is the primary pigment found in the chloroplast? Chlorophyll is the primary pigment found in chloroplasts. Photosynthesis Glucose is another name for sugar. The molecular formula for glucose is C 6 H 12 O 6. Plants make sugar by using the energy from sunlight to transform CO 2 from the air with water from the ground into glucose. This process, called photosynthesis occurs in the chloroplast of the plant cell. During this process, oxygen (O 2 ) is created as a waste product and is released into the air for us to breath. The formula for photosynthesis is: (reactants) (products) CO 2 + H 2 O + sunlight ----> C 6 H 12 O 6 + O 2 This formula says that carbon dioxide + water molecules are combined with the energy from sunlight to produce sugar and oxygen. The reactants in photosynthesis (what is used) are CO 2 , water and sun. The plant gets water from the ground through its roots. The plant collects carbon dioxide from the air. Much of the carbon dioxide comes from living organisms that exhale (breath it out) it, but some also comes from factory smokestacks and car fumes.
  7. What is the formula for photosynthesis? CO 2 + H 2 O + sunlight ----> C 6 H 12 O 6 + O 2
  8. What three things are used to make glucose in photosynthesis? Carbon Dioxide, water and sunlight are three things that are used to make glucose in photosynthesis.
  1. Where does the water come from? The water comes from in the ground.
  2. Where does the water enter the plant? The water enters the plants through the roots.
  3. Name 3 some sources of CO 2. Three sources of Carbon Dioxide are: exhalations from living organisms, pollution from factory smokestacks and car fumes.
  4. What type of energy does the plant use to convert CO 2 and H 2 O into sugar? Energy from sunlight is used to convert Carbon Dioxide and water into sugar. The products are glucose and oxygen. The glucose produced is used by the plant for energy and growth. We also use this glucose by eating plants. The oxygen produced is released into the air for us to breath. Photosynthesis is essential for all life on earth, because it provides food and oxygen. Plants are considered autotrophs because unlike us humans, they can make their own food using this process.
  5. What is produced in photosynthesis? Glucose and oxygen are the products of photosynthesis.
  6. What is the glucose used for? The glucose is used by the plant for energy and growth. Animals use the glucose for the same reason but get it by eating plants.
  7. What is the oxygen used for? The oxygen produced is released into the air for use by animals to breath.
  8. Here are three different ways to visualize the photosynthesis reaction: Is it easier for you to understand the reaction by using pictures, words, or symbols (see above)? Why?


Photosynthesis in pictures Photosynthesis in words Photosynthesis in symbols Carbon dioxide and water light combine with sunlight to CO + H^2 O → C^6 H^12 O^6 + O^2 create oxygen and glucose. Essential Question: Describe, using scientific terms, how plants turn sunlight into energy? Make sure to refer to the chemical equation to photosynthesis and discus the reactants and products. Plants take in sunlight, carbon dioxide and water to create glucose. They do this in the chloroplasts that are located in the leaves of plants. Oxygen is also a product of photosynthesis and gets released back into the atmosphere for animals to breath in.

  1. How do animals get rid of the carbon dioxide? Animals get rid of Carbon Dioxide by exhaling it into the atmosphere. What body system is involved with removing this waste? The respiratory and circulatory systems are involved with removing the Carbon Dioxide. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen is identical to the oxygen gas given off during photosynthesis.
  2. (Circle one) Oxygen is a PRODUCT OR REACTANT of respiration? (In other words, is it needed or released?)

13. Reflection Question: Explain the relationship between photosynthesis and cellular

respiration. Be sure to include the main purpose of both and where they occur inside the cell.

The products of one process are the reactants of another process. For example: water carbon dioxide, and sunlight are converted to glucose and oxygen in the chloroplasts during photosynthesis. Water, carbon dioxide and energy are the reactants in photosynthesis. Glucose and oxygen are the products in photosynthesis. In cellular respiration, glucose and oxygen are converted into energy, water and carbon dioxide. Glucose and oxygen are the reactants in cellular respiration and energy, water and carbon dioxide are the products in cellular respiration.
