Photosynthesis has 2 main steps which are light-dependent reactions and the Calvin cycle.

The final products of photosynthesis are oxygen and glucose.

Sunlight is necessary for photosynthesis to occur because the sunlight provides the initial energy which starts the cycle of photosynthesis when then converts the suns energy into food for the plants.

The two products that are the result of photosynthesis include a sugar called glucose and oxygen.

Without photosynthesis there would be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.

Photosynthesis actually only needs 4 things to occur and not 5 things.

The 4 requirements of photosynthesis are.

Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
Sunlight. The process cannot work without an energy input, and this comes from the sun.
Water.
Carbon Dioxide.

The 3 stages of photosynthesis are light-wave absorption, light-dependent reactions and light-independent reactions.

Some interesting things about photosynthesis are.

The green color of leaves is due to chlorophyll.
The two main parts of a chloroplast are the grana and stroma.
The first stage of photosynthesis captures energy from the sun to break down water molecules.

The second stage of photosynthesis is the Calvin cycle.

It takes six molecules of water and six molecules of carbon dioxide to make one molecule of glucose during photosynthesis.

Plants have specialized tissues that aid photosynthesis.

Glucose molecules join to form more complex molecules used by plants.

Leaves change color in autumn because plants slow down the process of photosynthesis.

Plants are not the only organisms that use photosynthesis.

The reverse process of photosynthesis is cellular respiration.

The two stages in photosynthesis are light-dependent reactions and light-independent reactions.

In photosynthesis the water comes from the oxygen atoms in the carbon dioxide molecules.

The 4 requirements for photosynthesis are water, sunlight, carbon dioxide and chlorophyll.

The end products of photosynthesis are oxygen and glucose.

The photosynthesis process is is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

The glucose in photosynthesis is used for energy and food in the plants.

Glucose is used by plants for energy and to make other substances like cellulose and starch.

Cellulose is used in building cell walls.

The role of sunlight in photosynthesis to create oxygen and create food for the plants.

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Cells create their food in plants by trapping the energy in sunlight and through photosynthesis.

In essence, the plant cell uses the energy in sunlight to combine carbon dioxide and water to make molecules of glucose and to release oxygen.

Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.

This transforms the water into oxygen and the carbon dioxide into glucose.

Chlorophyll and Carotenoids are pigments or chromophores which are involved in the photosynthesis process.

Both chlorophyll and carotenoids are responsible for harvesting light, absorbing photons and transferring the excitation energy to the photosynthetic reaction center.

Chlorophyll is what makes plants green.

Chlorophyll is located in a plant's chloroplasts, which are tiny structures in a plant's cells.

The process of photosynthesis produces oxygen, which is released by the plant into the air.

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light.

The oxygen in plants is used for respiration in the plants.

The plants need the oxygen for the process of respiration to be more efficient (known as aerobic respiration).

Plant cells are respiring constantly. When leaves are illuminated, plants generate their own oxygen

Plants process CO2 and extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves.

The carbon dioxide enters the leaves of the plant through small pores called stomata.

During this process, the plant combines carbon dioxide with water to allow the plant to extract what it needs for food.

Plants need sunlight for the process of photosynthesis to create oxygen and food.

All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy).

Plants require this energy in order to grow, bloom and produce seed.

Plants need direct sunlight as well as daylight.

However some plants can survive and thrive on mostly daylight and not need as much direct sunlight.

Through the process of photosynthesis, plants transform solar radiation into the energy they need to grow and thrive.

Plants that require full sun must grow outdoors and receive many hours of direct sunlight each day.

Nonetheless, many indoor plants manage just fine with indirect sunlight.

Sunlight is necessary for photosynthesis because the sunlight provides the initial energy that starts the cycle of photosynthesis, which converts this sun energy into food for plants.

The materials that are needed during photosynthesis are sunlight, carbon dioxide and water.

Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots.

Plants also require water to make their food.

The oxygen that is released from plants during photosynthesis comes from the splitting of water during the light-dependent reaction.

The electrons lost from the reaction center in photosystem II must be replaced.

The splitting of water serves to replace these lost electrons.

The plant after taking the oxygen in made through photosynthesis then releases the oxygen back into the air, and stores energy within the glucose molecules.

Trees make and produce oxygen through a process known as photosynthesis.

Through the process known as photosynthesis, leaves of plants pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree.

But as a by-product of that chemical reaction oxygen is produced and released by the tree.

The most important thing about photosynthesis is the oxygen it produces for the plants.

Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.

The importance of photosynthesis in our life is the oxygen it produces.

Without photosynthesis there would be little to no oxygen on the planet.

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

The two main functions of chloroplast is to conduct photosynthesis and to carry out functions like fatty acid and amino acid synthesis.

A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.

A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.

The chloroplast, found only in algal and plant cells, is a cell organelle that produces energy through photosynthesis.
