What is the process of photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.

What does photosynthesis produce?

Photosynthesis is the process of creating sugar and oxygen from carbon dioxide, water and sunlight. It happens through a long series of chemical reactions. But it can be summarized like this: Carbon dioxide, water and light go in. Glucose, water and oxygen come out.

What uses photosynthesis?

Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.

Where does photosynthesis occur in a plant?

chloroplasts 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 with diagram?

Photosynthesis is the process of preparing food in the presence of sunlight and chlorophyll. In this process, the plant uses water from the soil, carbon dioxide from the air. It occurs in green plants, certain algae, blue-green algae and bacteria.

What is photosynthesis explain with the help of diagram?

Answer: Photosynthesis is the conversion of light energy into chemical energy, which is then used to drive cellular activity in green plants and other organisms. The chemical energy is stored as sugars, which are made from water and carbon dioxide, while oxygen is produced as a by-product of the process.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.

Why are plants green?

So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light.

How do plants grow?

When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

What is photosynthesis explain with diagram?

What are the 7 steps to 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.
Step 3- Light Dependent. The electrons move down to enzymes.
Step 4-Light Dependent. …

What does photo in photosynthesis refer to Class 7?

Answer: 'Photo' in photosynthesis refers to light.

What is photosynthesis PDF?

Photosynthesis is a chemical process. that converts carbon dioxide into different organic compounds using solar energy. Oxygenic. and anoxygenic photosynthesis undergo different reactions in the presence and absence of. light (called light and dark reactions, respectively).

What is a meaning photosynthesis diagram?

Photosynthesis Diagram According to the diagram of photosynthesis, the process begins with three most important non-living elements: water, soil, and carbon dioxide. Plants begin making their 'food', which basically includes large quantities of sugars and carbohydrate, when sunlight falls on their leaves.

What is the true color of a leaf?

True colors come from inside The four primary pigments that produce color within a leaf are: chlorophyll (green); xanthophylls (yellow); carotenoids (orange); and anthocyanins (reds and purples).

Can plants see Colour?

'Invisible' light Although plants are a bit color blind, they do sense colors, more appropriately energy levels, that are entirely invisible to us humans. For example, plants can perceive far-red light.

What makes plants green?

What is a plant for kids?

What are plants? Plants are living things that grow from the soil and turn light from the Sun into food. Plants can be big or small, from giant trees to tiny patches of moss. Plants use a process called photosynthesis to turn sunlight into food in their leaves.

How do you explain photosynthesis to a child?

What means photo in photosynthesis?

Photosynthesis, comes from two words, photo meaning ''light'' and synthesis meaning "to make". Photosynthesis evolved billions of years ago as a way for the first living cells to make their own nutrition from commonly occuring natural elements of air, water and light.

What are the 3 stages 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

Is grass actually green?

Answer 1: Grass is green because it contains a chemical called chlorophyll. Chlorophyll allows the plant to absorb energy from sunlight but not all of the energy. Because sunlight is actually composed of many colors, plants absorb energy from most all of the other colors except green and a few others–but mostly green.

Do plants have eyes?

These rods and cones contain protein pigments which absorb certain wavelengths (colors) and eventually transmit this information to the brain. Obviously plants don't have eyes. However, they are able to “sense” and physiologically respond specifically to the ratio of red light and far-red light, and blue light.

Can plants hear you?

Here's the good news: plants do respond to the sound of your voice. In a study conducted by the Royal Horticultural Society, research demonstrated that plants did respond to human voices.

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.

Why are leaves called leaves?

Leaf comes from the Old English word 'lēaf', which is of Germanic origin and related to the Dutch 'loof' and German 'Laub'.

How do flowers grow?

Flowering plants grow from seeds The embryo inside the seed starts to grow into a seedling. Roots grow down to anchor the plant in the ground. Roots also take up water and nutrients and store food. A shoot grows skywards and develops into a stem that carries water and nutrients from the roots to the rest of the plant.

What means photo?

Definitions of photo. a representation of a person or scene in the form of a print or transparent slide; recorded by a camera on light-sensitive material. synonyms: exposure, photograph, pic, picture.
