Whether Chrolohyll important for plant to photosynthesis

Title:whether chlorophyll will affect plants to photosynthesis

Aim:To find out whether chlorophyll is necessary for photosynthesis.

Hypothesis:Plants need chlorophyll for photosynthesis.

To find out whether chlorophyll is needed for plants to photosynthesis.I will take two different colour of leaves for the test.one of the leaf being a green leaf and another being another type of leaf that does not contain chlorophyll . As one of the plant went through photosynthesis. When I add the iodine solution to it. It will turn into dark black to show that starch is present and photosynthesis has taken place. The relationship between both leaves is that if both plant turn into dark black it shows that chlorophyll is not necessary for plants to photosynthesis. However if only the green leaf turn into dark black, it shows that chlorophyll is needed for photosynthesis to take place.

The independent variables are the two different collies of leaves And dependent variables are whether the leaves will turn black.For the experiment to be a fair test I will take both leaf from the same plant but different part of it. And I will boil both leaf together.

Procedure:

Step 1:Prepare a hot water bath

Step 2:Boil 1 leaf in hot water about 2-3 minutes.

Step 3:After boiling the leafdry it.

Step 4:Place the leaves on a white tile and drop few drop of iodine solution into both leaves.

Step 5:Take a new green leaf out and put both leaf until den light for photosynthesis 10mins

Step 6:Record down the result. Whether both leaves turn dark blue or only green leaf.

Materials:

1 boiling tube1 beaker1 tripod stand 1 lighter 2 leaf from the same plant but different part 1 iodine solution and 1 Bunsen burner and teat tube holder 1 piece of white tile.

RESULT:

The iodine solution in the boiled leaf does not change it's colour and remain yellow,but the iodine solution in the green leaf change it's colour to dark blue.

Conclusion:

Plant needs chlorophyll to photosynthesis.because when plant loss it's chrolophyll in boiled it cannot photosynthesis.

Similarities and differences of photosynthesis and respiration.

Photosynthesis is the process by which plants take in the elements sunlight, water and carbon dioxide to produce food for the producer. The substances released from the caused reaction are oxygen and sugar. Sugar can also be put as the term glucose. Cellular respiration is basically the opposite Cellular respiration can be used by a producer as well as a consumer to make food and energy. In this, the consumer or producer take in both oxygen and glucose, and the substances released from the reaction are carbon dioxide and water.

Photosynthesis in the Dark

1.Can plants photosynthesis without sunlight?

No.Because chlorophyll is the molecule which orchestrates the coming together of light and water and CO2 to make sugars.Without it nothing would happen.Light is the energy source which allows high-energy molecules like sugar to be built from low energy molecules like water and carbon dioxide.Without the energy source nothing would happen.


2.How do deep sea plants survive?


They don't undergo the photosynthesis cycle unlike other plants because of the absence of light. They survive entirely absorbing nutrients present in the soil.The soil is very rich in nutrients because all dead fish settles on the deep ocean floor.


3.How did Photosynthesize happen in Green Sea Slug?

A green sea slug appears to be half animal and half plant.It's the first critter discovered to produce the plant pigment chlorophyll.The slugs have stolen the genes that enable genes from algae that they had eaten.With their contraband genes,the slugs can carry out photosynthesis the process which plants use to convert sunlight into energy.They can make their energy containing molecules without having to eat anything.In addition to burglarizing the genes needed to make the green pigment chlorophyll,the slugs also steal tiny cell parts called chloroplasts,which they use to conduct photosynthesis.The chloroplasts use the chlorophyll to convert sunlight into energy,just as plants do.






Here are some green sea slug pictures.

Photosynthesis

This is a picture shows how photosynthesis is work.

1. What happen if there is no more photosynthesis?

If light was suddenly stop,photosynthesis would stop.Because the driving energy behind photosynthesis is chemical energy which is created directly from sunlight.Without photosynthesis there will be increasing of carbon dioxide and too much of carbon dioxide will leads to global warming.without photosynthesis Plants cannot make their own food so that they need oxygen to survive and there will be decreasing of oxygen,soon all living things in earth will come to the end.

2.Why is photosynthesis important to plants and animals?

The process of photosynthesis provides plants with the food and energy they need to sustain themselves.By using energy from sunlight the plant can make their own foods,which is a conversion of light energy to potential energy.Then the plants will release the potential energy to do necessary work.Photosynthesis is equally important to most animals because animals cannot produce their own foods,they are known as heterotrophs.Animals get foods energy directly or indirectly from the plants that photosynthesis.

3.How does the photosynthesis afftect the human?

Photosynthesis affects human because it gives us air and helps us breathe.if there were no photosynthesis plants wonldn't grow and that wonldn't only mess up our ecosystem we wonld all die because we have no air and then there wonld be no use for the sun.

Photosynthesis And Respiration

1. Photosynthesis and respiration are opposite. As the plants photosynthesis they will take in carbon dioxide and give out oxygen , while other living things respire they will take in oxygen and give out carbon dioxide.

2.What is photosynthesis and where did it found?

Photosynthesis is the process used by plants to create energy from sunlight. Chlorophyll is the green pigment found in plants that is responsible for this conversion process. Photosynthesis converts light energy into chemical energy, and stores it in sugar. This process occurs in the chloroplasts, using chlorophyll. The chemical formula for the process requires six molecules of carbon dioxide and six molecules of water plus the energy from sunlight. This creates a sugar chain and six units of oxygen. Chlorophyll is green because the light required for photosynthesis is red and blue light. Leaving green light to be reflected back to our eyes. Photosynthesis occurs in the leaves of plants and there is still little in the stems. Plant leaves are made of upper and lower epidermises, mesophyll, veins and stomatas. Mesophyll is the layer of the plant that contains chloroplasts and is the only place photosynthesis occurs. The energy taken is stored as adenosine triphosphate. It is required for energy storage and is made of the nucleotide adenine with ribose sugar.

4.What is respiration?

In all living things, they rely on the process of respiration to stay alive. Respiration is the process of taking oxygen from the air and cycling it through the lungs, which then gives oxygen to bloog to be used in the body. The carbon dioxide waste is expelled out from the lungs. The respiration system allows liveing creatures that are not plants to obtain oxygen from the air for use in the blood and cells. Oxygen is much needed nutrient and living organisms can roughly only survive for minutes without it.

4.The different between photosynthesis and respiration?

The main difference between photosynthesis and respiratiis where is occurs, one being in plants and the other being in almost every other living things. The other difference is that plants require sunlight for the process to occur.where respriration does not.But there is an important mutual relationship between the two processes because of the ingredients required, and products produced. plants take carbon dioxide and expel oxygen, and almost other living things take in oxygen and expel carbon dioxide, the importance of both systems working in unison is obvious.

5.why is photosynthesis important?

The importance of Photosynthesis can be understood with respect to our breathing process. The breathing process keeps us alive and photosynthesis provides us oxygen to breathe in.
