In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
How does photosynthesis work quizlet?
How does photosynthesis work? Plants use sunlight and simple substances to produce sugars and oxygen. Water is taken in through the roots and transported through the plant to the leaves. Plants take in carbon dioxide (CO2) from the air through the stomata, or pores in leaves.

How do chloroplasts work?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. … Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
What are the sites of photosynthesis describe its structure with a neat and Labelled diagram?
Answer: Grana are the sites for the light reaction and stroma is the site for the dark reaction of photosynthesis. Each granum is made up of a stock of closed compartment called thylakoids. … The stacks of thylakoids sacs are connected by stroma lamellae.
What is the function of the photosynthetic pigments in photosynthesis?
Photosynthetic pigments are the molecules responsible for absorbing electromagnetic radiation, transferring the energy of the absorbed photons to the reaction center, and for photochemical conversion in the photosynthetic systems of organisms capable of photosynthesis.
What is photosynthesis quizlet?
Definition of Photosynthesis. Photosynthesis is the process by which green plants, algae and some forms of bacteria use energy from sunlight to convert carbon dioxide and water into glucose.
Where does the process of photosynthesis occur quizlet?
Photosynthesis occurs in the chloroplast.
Which is an example of why the process of photosynthesis?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.
What is photosynthesis answer for Class 4?
Textbook solution
Photosynthesis is the process in which green plants use chlorophyll, sunlight, carbon dioxide and water to make their own food. Chlorophyll helps to trap sunlight(light energy), plants take up carbon dioxide from air and absorb water from soil.
What are the key steps in the process of photosynthesis?
The stages of photosynthesis
| Stage | Location | Events |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Light energy is captured by chloroplasts and stored as ATP |
| Calvin cycle | Stroma | ATP is used to create sugars that the plant will use to grow and live |
How do you explain photosynthesis to a child?
How does photosynthesis work AP Bio?
Photosynthesis allows organisms to access enormous amounts of free energy from the sun and transform it to the chemical energy of sugars. … Photosynthesis is a process where components of water and carbon dioxide are used to assemble carbohydrate molecules and where oxygen waste products are released into the atmosphere.
How do plants photosynthesize?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
What are the two stages of photosynthesis called?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What is the overall equation for photosynthesis worksheet?
1. What is the overall equation for photosynthesis? 6 CO2 + 6 H2O → glucose (C6H12O6) + 6 O2 It is the reverse of the overall reaction for cellular respiration.
Where do electrons end up in photosynthesis?
In cellular respiration, electrons flow from glucose to oxygen, forming water and releasing energy. In photosynthesis, they go in the opposite direction, starting in water and winding up in glucose—an energy-requiring process powered by light.
What are the 5 stages of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

What is the label for the structure that can make sugar from light energy?
Chloroplasts
Chloroplasts – Show Me the Green Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Why do leaves appear green?
Chlorophyll’s job in a plant is to absorb light—usually sunlight. … Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.What happens in each of the two main stages of photosynthesis quizlet?
The two stages of photosynthesis are light reactions and the Calvin Cycle. Light reactions occur within the thylakoids and the Calvin Cycle takes place in the stroma. The light reactions create ATP and NADPH, which are used by the Calvin Cycle which also brings in carbon to produce sugar.
What is the role of key organelles in energy transfer?
Light energy is converted into electrical energy. Which statement accurately describes the role of key organelles in energy transfer? … Energy is captured and stored in the chloroplast and released in the mitochondria. Energy is captured and stored in the mitochondria and released in the chloroplast.
How does photosynthesis occur in chloroplasts?
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
What is structure of chloroplast?
Chloroplasts are enclosed by an envelope of two membranes which encompass a third complex membrane system, the thylakoids, including grana and lamellae. In addition, starch grains, plastoglobules, stromules, eyespots, pyrenoids, etc. are also important structures of chloroplasts.

The chloroplast contains three main pigments that absorb light energy, chlorophyll a, chlorophyll b, and carotenoids. Chlorophyll is most abundant in the thylakoids. … In eukaryotes, it occurs in the thylakoid membrane of the chloroplast. In eukaryotes, the dark reaction happens in the stroma of the chloroplast.
