Newsela: Learn the photosynthesis formula

Where does photosynthesis mainly occur in plants?

• Roots

• Leaves

• Flowers

• Stems

Answer explanation

Photosynthesis mainly occurs in leaves of plants where chlorophyll captures sunlight to convert carbon dioxide and water into glucose.

What is the primary source for the photosynthesis process?

• Sunlight

• Soil nutrients

• Water

• Carbon dioxide

Answer explanation

The primary source for the photosynthesis process is sunlight, as it is the energy source used by plants to convert carbon dioxide and water into glucose.

How does Photosynthesis primarily contribute to the environment?

• By converting light energy into chemical energy

• By increasing global temperatures

• By regulating water cycles

• By facilitating plant reproduction

Answer explanation

The main topic of the article is photosynthesis, as indicated in the question and confirmed in the correct answers section.

What is the main chemical compound that stores and releases energy during photosynthesis?

• ATP

• Cytoplasm

• PTP

• Oxygen

Answer explanation

The main chemical compound that stores and releases energy is ATP.

Match the following parts of the cell to their functions:

• Stroma

• Organelle responsible for photosynthesis in plants

• Thylakoids

• Space in the chloroplast where the Calvin Cycle occurs

• Chloroplast

• Membrane in the chloroplast where light reactions occur

• Chlorophyll

• Green pigment that absorbs light energy

During photosynthesis, plant cells contain (a)   that produce glucose for the plant. These are located in the (b)   of the cell and contain stacks of (c)   within them.

• chloroplasts

• cytoplasm

• granum

• chlorophyll

• thylakoids

• mitochondria

• nucleus

Answer explanation

Plant cells contain chloroplasts that make sugar for the plant. They can be found in the cytoplasm of the cell and have stacks of granum inside of them.

Consider the natural process occurring in plants. _. 6CO2+6H2O→C6H12O6+6O2. This equation represents the process of photosynthesis. In this process, C6H12O6 stands for- (a)  

• water

• glucose

• chloroplast

• carbon dioxide

Answer explanation

The equation for photosynthesis produces glucose (C6H12O6), not water, chloroplast, or carbon dioxide.

During photosynthesis, what is the name of the pigment molecule that captures sunlight and gives plants their green color?

• chloroplast

• glucose

• mitochondria

• chlorophyll

Answer explanation

The name of the pigment molecule that absorbs light energy and makes plants green is chlorophyll.

The process of using sunlight, carbon dioxide, and water to make sugar and oxygen is called _________?

• chlorophyll

• evaporation

• photosynthesis

• transportation

Answer explanation

The correct answer is photosynthesis because it is the process of using sunlight, carbon dioxide, and water to make sugar and oxygen.

What is the primary role of chloroplast in plants?

• Mitosis

• Meiosis

• Translation

• Photosynthesis

Answer explanation

The main function of chloroplast is photosynthesis, where it converts light energy into chemical energy to produce glucose for the plant.
