Answer:
first ask one question at a time dont mess like this
ANYWAY iam answering
Explanation:
- 6CO2 + 6H2O → C6H12O6 + 6O2. is formula as per latest version
Products glucose +oxygen
conditions-To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis.
- I dont know whelther u are higher class or not but even i will say tjis (HOTS) that by without sunlight photosynthesis. can occurer using energy of atp which occures in calvin RUBISCO (if u dont know it leave it as it is higher class concept
2. they are fungi and algae
benefit- fungi generally provides shelter whereas algae being photosynthetic prepares food and provide nutrition and hence both are benefitted
3.activity of my practical
GIVEN BELOW
AIM: Tp prove carbon dioxide and water are the essential aw materials for plants
Apparatus required:
A healthy potted plant
A wide-mouthed glass bottle with a split cork
Potassium hydroxide solution (KOH)
Starch solution.
PROCEDURE
Take a healthy potted plant and place it in the darkroom for two to three days
In a wide-mouthed glass bottle add 10-15 ml of potassium hydroxide solution and split the cork vertically
Then insert half part of a leaf into a glass bottle through the split cork and the other half of the leaf should be exposed to air
Allow this apparatus undisturbed for 4 hours
After 4 hours detach the leaf from the plant, remove from the bottle and test it with the starch solution.
Observation from the experiment:
The half part of the leaf kept inside the glass bottle (KOH solution) did not show any color change.
The other half part exposed to surroundings turned its color to dark brown which shows the presence of starch.
CONCLUSION
We can conclude that carbon dioxide and water are essential for photosynthesis. Both the portion of leaf received the same amount of water, chloroplasts, and sunlight but the half part which was inside the glass bottle did not receive carbon dioxide and water hence the photosynthesis process did not occur here.
.4. The presence of starch in leaves can be tested by Iodine test. When we remove chlorophyll from leaf by boiling it in alcohol and then put 2 drops of iodine solution, its colour change to blue indicates the presence of starch.
5.Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Light energy is converted into chemical energy. ... With photosynthesis, chlorophyll absorbs energy and then transforms water and carbon dioxide into oxygen and carbohydrates. also it helps to increase atp and nadph molecules (HOTS)
6.plants contain nitrogen-fixing bacteria (Rhizobium) attached to their roots. ... these plants help to replenish the nutrients like nitrogen in the soil.
