Answer: Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials.
What is photosynthesis Quizizz?
What is photosynthesis? The process by which plants turn sunlight, water, and carbon dioxide into food and oxygen. The process by which plants turn oxygen and food into carbon dioxide and water.
What photosynthesis needs Quizizz?
Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis. Plants use chlorophyll, water, and carbon dioxide to make sugar.
Which statement about photosynthesis is true Quizizz?
Q. Which statement about photosynthesis is correct? Plants get the energy they need for photosynthesis from water. Plants get the energy they need for photosynthesis from soil.
What are the 3 stages of photosynthesis?
The stages of photosynthesis
|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|
Why photosynthesis is called dark reaction?
Instead, dark reaction uses ATP and NADPH to produce energy molecules. No photosystem is required. Photolysis of water does not occur. So, the dark reaction in photosynthesis is called so because it does not require light energy.
What makes plants green?
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. Plants that use photosynthesis to make their own food are called autotrophs.
What organelle performs photosynthesis?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
What is 6CO2?
6CO2 means there are 6 number of Carbon dioxide present ( or required to complete a reaction) Biology.
What are some good questions to ask about photosynthesis?
Photosynthesis test questions
- What is the role of chlorophyll?
- Which useful energy conversion is carried out by chlorophyll?
- What are the products of the light reactions?
- In photosynthesis, what is ATP required for?
- In which cell organelles does carbon fixation occur?
What two materials are needed for photosynthesis Quizizz?
Q. What two materials are needed for photosynthesis? Water and soil.
Where is chlorophyll found in the chloroplast?
What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.
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.
Do plants need carbon dioxide to grow?
The logic is straightforward: Plants need atmospheric carbon dioxide to produce food, and by emitting more CO2 into the air, our cars and factories create new sources of plant nutrition that will cause some crops and trees to grow bigger and faster.
Why are most plants green Quizizz?
Green is the color being absorbed by the leaf. All the colors are being reflected off the leaf. All the colors are being absorbed by the leaf.
What is the main pigment for photosynthesis?
There are several kinds of chlorophyll, the most important being chlorophyll “a”. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll “a”.
What is the main pigment in plants?
Chlorophylls. The chlorophylls, a and b, are the pigments of photosynthesis. They are produced in chloroplasts in the photosynthetic tissues of the leaf. The chlorophyll molecules are very water repelling, partly because of the long phytol tail in the molecule.
What is the last part of photosynthesis?
Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is a process in which green plants use sunlight to make their own food.
What are the materials of photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Where does the rate of photosynthesis?
As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .
Which is the first step in photosynthesis?
The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process. In the first stage, light energy is captured and converted to chemical energy.
What color light is best for photosynthesis?
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.
Why is photosynthesis important?
Photosynthesis is arguably the most important biological process on earth. By liberating oxygen and consuming carbon dioxide, it has transformed the world into the hospitable environment we know today.
What sugar is formed in photosynthesis?
Photosynthesis happens in small compartments within the plant cells, called chloroplasts. In a two-step process, plants obtain chemical energy from sunlight. The collected energy is used in a second reaction to produce the sugar glucose.
What cells are used in photosynthesis?
Chloroplasts are organelles in plant and bacteria cells that contain the chlorophyll used in photosynthesis. They are bound by a double membrane that contains many folds
this double membrane encloses many other membranous structures, called thylakoids.
What are plants called?
Current definitions of Plantae
|Land plants, also known as Embryophyta||Plantae sensu strictissimo|
|Green plants, also known as Viridiplantae, Viridiphyta, Chlorobionta or Chloroplastida||Plantae sensu stricto|
|Archaeplastida, also known as Plastida or Primoplantae||Plantae sensu lato|
Do chloroplasts have DNA?
Each chloroplast contains a single DNA molecule present in multiple copies. The number of copies varies between species
however, the pea chloroplasts from mature leaves normally contain about 14 copies of the genome. There can be in excess of 200 copies of the genome per chloroplast in very young leaves.
What is C6H12O6 called?
Glucose is a simple sugar with the molecular formula C6H12O6.
What is in chloroplast?
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.
What is photosynthesis formula?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
