Based on Activity 2, what are the factors that will affect the rate of photosynthesis? by Molecules

Some factors that I would be elaborating on:

1) The amount of Carbon Dioxide given to the plant in the water. (also known as CO²)

As if this was to be changed, the amount of oxygen bubbles would be (if the variables are kept constant at the length: 4cm away from set-up, light colour: blue, temperature: 30^oC.):

0.02% = 40 bubbles
0.04% = 81 bubbles
0.06% = 97 bubbles
0.08% = 97 bubbles

2) The colour of the light given to the plant in the water.

As if this was to be changed, the amount of oxygen bubbles would be (if the variables are kept constant at the length: 4cm away from set-up, CO2 levels: 0.06%, temperature: 30^oC.):

Red coloured light = 87 bubbles
Yellow coloured light= 58 bubbles
Green coloured light= 48 bubbles
Blue coloured light= 97 bubbles

3) The temperature of the water surrounding the plant.

As if this was to be changed, the amount of oxygen bubbles would be (if the variables are kept constant at the length: 4cm away from set-up, light colour: blue, CO² levels: 0.06%.):

10^oC = 39 bubbles
20^oC = 77 bubbles
30^oC = 97 bubbles
40^oC = 48 bubbles

4) The distance from the light lamp and the plant in the set - up. (Intensity of light)

As if this was to be changed, the amount of oxygen bubbles would be (if the variables are kept constant at the CO² levels: 0.06%, light colour: blue, temperature: 30^oC.):

0cm away = 122
2cm away = 109
4cm away = 97
6cm away = 83
8cm away = 69
10cm away = 56

5) The type of plant used in he experiment (e.g. Grass, Morning Glory, Poppy, Rosemary, Huckleberry, Thistle, Pea, Corn, Watermelon, Dragon Fruit, Starfruit, red bean, sunflower, Mistletoe, Bearberry, Banana, blueberry, strawberry, grapes, apples, Carrion Plant, Bayan Tree, Tomatoes, Seagrass, Passionfruit, Japanese Iris, Cactuses, Raspberry, Eucalyptus etc.)

As different plants can do different things, such as (e.g. cactuses can live for a long time without water, etc.)

6) The environment that the plant is in during the experiment. (e.g. Dessert, Jungle, Forrest, Ocean/Sea, Lake, Stream, Waterfall, Plains, Grasslands, Rain Forrest, Tropical, Savannah, Marsh, Hills, Mountains, Valleys, Canyons, peninsulas, ponds, creeks, channels, swamps, straits, gulfs, bays, rivers, coastlines, beaches, houses, gardens, lawns etc.)

As if the environment/terrain type changes, it might affect the plant in different ways, most of them lethal and would kill the plant, making them die (Surprise!!!)

if not taken or transferred immediately to another area.

7) The amount of rainfall per day/week/month/year/decade/century/millennia. (e.g. 100 milliliters yearly, 10000 litres monthly etc.)

As this would also affect the amount of food the plant can make to sustain itself. If there is too little rainfall, it would die due to dehydration. Too much rainfall, and the water would clog the soil and air would not be able to get to the roots. Thus, making the plant die due to a lack of oxygen.

8) Amount of sunlight per day/week/month/year/decade/century/millennia. (e.g. 10 W/m² which stands for watts per square meter 10000 W/m². etc.)

As this would also affect the amount of food the plant makes for itself. if there is too little sunlight, it would die due to starvation. If Plants harvest too energy from the sun, using chlorophyll and carotenoid, two photon-capturing molecules, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.

9) Amount of mineral nutrients in the soil that the plants has been planted in. (e.g. Amount of NO3-, Na+, K+, chlorophyll, pH, EC etc.)

As this would effect the growth of the plant and also affecting the amount of food made. Thus, changing the amount of oxygen produced by the plant. If there is too little mineral nutrients in the soil, the growth of the plant would be slowed down. And if the soil organic matter levels surpass 8%, it can lead to excessive mineral nutrient availability and other problems that would be deadly to the plant causing it to die. (Surprise again!!!)

10) The composition of the atmosphere around the plant.

The composition of the atmosphere is made out of Nitrogen = 78.0%
Oxygen = 21.0%
Argon = 0.9%
Trace gases* = 0.1%

This would also affect plants as global warming and air pollution occur, it creates acid rain in the atmosphere which instead harms plants instead of normal water which is needed for the plant to survive. Global warming has also made air pollutants called chlorofluorocarbons(or CFCs) to destroy parts of the ozone layer. The ozone layer, located in the stratosphere layer of Earth's atmosphere, shields our planet from the Sun's ultraviolet radiation. The areas of thin ozone are called ozone holes. Ultraviolet radiation causes skin cancer and damages plants.

11) The genes of the plant you are using. (e.g. If the plant's genes allow it to grow very quickly, the plant would photosynthesize very quickly and constantly. )

12) The composition of the soil the plant is growing in.

Composition:
Very coarse sand:
system Diameter (mm) = 2.00 - 1.00
Number of particles per g = 90
Coarse sand:
system Diameter (mm) = 1.00 - 0.50
Number of particles per g = 720
Medium sand:

system Diameter (mm) = 0.50 - 0.25
Number of particles per g = 5,700
Fine sand:
system Diameter (mm) = 0.25 - 0.10
Number of particles per g = 46,000
Very fine sand:
system Diameter (mm) = 0.10 - 0.05
Number of particles per g = 722,000
Silt:
system Diameter (mm) = 0.05 - 0.002
Number of particles per g = 5,776,000
Clay:
system Diameter (mm) = below 0.002

Number of particles per g = 90,260,853,000

Other Factors: Biotic factors,

Absence of growth-restricting substances, Soil aeration, Soil reaction, Plant Nutrients, Non-mineral nutrients (from water and air), Macronutrients, Micronutrients, concentration of NaHC_O, Water Contents, Protoplasmic Conditions, presence of cyanides, azides and fluorides, presence of Chlorides made of various minerals, like sodium, potassium, calcium and magnesium, Relative Humidity, Wind.

* Trace gas is composed of: Carbon Dioxide = 93.497%
Neon = 4.675%
Helium = 1.299%
Methane = 0.442%
Nitrous Oxide = 0.078%
Ozone = 0.010%
