Explanation

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

• The greenhouse effect occurs when certain gases in the atmosphere trap heat from the Sun.
• Key greenhouse gases include CO₂, CH₄ (methane), N₂O, and water vapor.
• These gases allow sunlight to enter but absorb and re-radiate infrared radiation back to Earth.
• This process warms the planet, making life possible.

Explanation

IMPORTANT QUESTIONS AND INFORMATION RELATED TO "GREEN HOUSE EFFECT"

Green House Effect means the Trapping of Solar energy due to atmospheric carbon dioxide

The greenhouse effect is a good thing.

It warms the planet to its comfortable average of 57 degrees Fahrenheit (13.9 degrees Celsius)

The greenhouse effect keeps life on earth, well, livable.

The Green House Effect is caused by an excess of Carbon dioxide

The greenhouse effect causes Global warming

Methane gas is 80 times potent than CO2 in Green House Effect

Explanation

The stratosphere is a layer of Earth's atmosphere.

It is the second layer of the atmosphere as you go upward

Explanation

Why lightning comes faster than thunder? 5 marks

Lightning is faster than thunder.

• Lightning and thunder happen at the same time.

• But you see lightning before you hear thunder

• because light, which travels a million times faster than sound, arrives almost instantly.

• Sound, on the other hand, takes about five seconds to travel one mile.

• light at a speed of around 300,000,000 meters per second travels much faster than sound which moves at 340 meters per second.

Explanation

Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.

Explanation

Radiation is very slow on cloudy nights, resulting in less condensation on cloudy nights. 

 On cloudy nights, the clouds are thick  and trap  heat and water vapor in the clouds, resulting in very slow radiation. 

 This all shows why  dew levels drop on cloudy nights.

Explanation

• Producers, also known as autotrophs.
• They are organisms that can produce their own food through photosynthesis, using water (H2O), carbon dioxide (CO2), and sunlight to produce glucose and oxygen.
