2. To transport water to the entire plant, especially the leaves where photosynthesis takes place. This is important because water is required for photosynthesis to take place.

3. Chlorophyll.

4. The palisade layer contains the most chloroplasts.

5. The function of the stomata is to allow gas exchange to facilitate photosynthesis. It also controls the rate of photosynthesis to regulate water use of the plant. Without it, plant would have severely hindered transpiration, causing the plant to die.

6. Chloroplasts are where photosynthesis takes place. Without chloroplasts, no synthesis would happen.

7. A leaf from a desert plant would likely have less stomata to conserve water content in the plant from evaporation due to environmental factors. This is because water escapes to the environment when stomata are open in plants. The contrary would be the case for plants in a tropical environment where water is more abundant and sunlight is more lacking.

Explanation:

.For the our health because if the environment is saved the we are able to get the fresh air.

.For decreasing global warming because if environment is saved then the pollution is controlled.

.For decreasing deforestation which can control landscape because saving the environment can also be taken as saving trees.

For saving the animals because the habitat of animal is forest which need to be protected by protecting environment.

.For saving the natural resource which are also the reasons of income because it attracts tourists.

Why does changing the PH of a solution affect the ability of enzymes?

WARRIOR [948]

Enzymes can be denatured by irregular PH. Meaning that they can change shape. Enzymes rely on their shape in order to function so if their shapes change because of the PH then the active sites don't fit anymore and they enzymes wont work.

Step by step process of photosynthesis

klasskru [66]

Answer:

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. Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent. The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

calvin cycle.
