Additional info

This is a collection of information that I cannot seem to properly fit into this article... so I will leave it here:

5 reasons cells require energy

1. Use energy to carry out active transport
2. Synthesis of proteins and nucleic acids
3. Responses to chemical signals at the cell surface
4. Movement (motor proteins) of organelles around the cell
5. Used to produce light in some organisms, such as fireflies

Definitions

1. Stomate - Opening in plant leaves that allow gases (CO₂ and O₂) to enter/leave the cell.
2. Guard cell - Cells that open and close the stomata^{("Stomata" def. is explained in the article)}.

Removed content

Hello. I've removed the following content from the page:

Obtainment of Materials

Water

In a vascular plant, pipe-like tissues conduct water to different parts of the plant. In a non-vascular plant, water is unable to be conducted, and, therefore, must be absorbed from the plant's surroundings.

Carbon Dioxide

Stomata are pipe-like structures in the leaves that control the flow of carbon dioxide into a plant and the flow of oxygen outside of the plant.

Sunlight

Light is absorbed by molecules called pigments. In plants, the green pigment that absorbs sunlight is found in the chloroplasts, named "chlorophyll".

Chlorophyll absorbs sunlight energy and transfers it to chemicals involved in the photosynthetic process. Sunlight contains all the colors of the rainbow (Roy G. Biv). All the colors hit the chlorophyll molecules, but only certain colors are absorbed. Chlorophyll absorbs well in the blue-violet and red sections of the visible light spectrum, whereas chlorophyll reflects most of the green light in the visible light spectrum, giving most plants a green color.

The chloroplast is where photosynthesis happens in plants.

I did this so that I can take time to reorganize and contribute to this article with my knowledge. I'm finding it difficult to add in material here due to the jumbled-up structure here. Hopefully, I can implement this part of the article back into the article--as removing someone else's work randomly out is just disrespectful in itself. ---Atcovi (Talk - Contribs) 15:55, 4 January 2018 (UTC)

The Chloroplast

The chloroplast is where photosynthesis happens in plants.

The light reactions of photosynthesis.

The Stroma

• The area of the chloroplast not taken up by the thylakoids
• The Calvin Cycle occurs here

Removed content #3

from the Sun to convert water (H₂O) and carbon dioxide (CO₂) into energy-rich glucose (C₆H₁₂O₆) and oxygen (chemical energy).

The chemical equation for photosynthesis is (reactants on the left, products on the right):

energy from the Sun + 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

---Atcovi (Talk - Contribs) 17:11, 4 January 2018 (UTC)

Photosynthesis consists of two sets of reactions: the light-dependent reactions and the light-independent reactions (otherwise known as the Calvin Cycle).

Extra definitions

Couldn't smash these definitions in the article, so I'll put them here instead. For anyone interested in learning more about Photosynthesis: heres a photosynthesis matching worksheet I had to complete in class. Hope people benefit from them:

1. Food - the energy source for consumers
2. Stroma - liquid-filling of chloroplasts
3. Gaurd cell - One of two cells that control the opening and closing of stomates
4. Oxygen - Atmospheric gas produced by photosynthesizing plants
5. Heterotrophic - Means, "must eat food to make ATP energy.".
6. Grana - A stack of thylakoids inside a chloroplast.
7. Red and Blue - Chlorophyll molecules absorb these two wavelengths of light.
8. Sunlight - The energy source that powers most food chains on earth.
9. NADPH - Energy carrier molecule that transports hydrogen atoms to the Calvin Cycle
10. NADP - This molecule can "pick up" a hydrogen atom
11. Autotroph - Means, "can make ATP energy from sunlight.".
12. Green - Wavelength of light that is useless to plants.
13. Chemical - Type of energy stored in ATP, NADPH, and glucose.
14. Solar - Type of energy produced by fusion reactions inside a star.
15. Chloroplasts - Organelle containing pigments and compartments capable of doing photosynthesis.
16. Work - What all cells do when they grow, move things around.
17. Stomate - An opening in the lower epidermis of a leaf.
18. C02 - Atmospheric gas needed by plants for its carbon atoms.
19. Wavelength - What makes colors different from each other.
20. Carbon Fixation - Another name for Calvin Cycle.
21. ATP - The universal energy carrier molecule of all living cells.
22. Water - Molecule needed by plants as a source of hydrogen atoms.
23. Calvin Cycle - The part of photosynthesis that actually builds glucose molecules.
24. ADP - ATP minus a phosphate group
25. Thylakoid - Green, flattened vesicles inside a chloroplast where photosynthesis happens.
26. Lower epidermis - Part of a leaf where stomates are located.
27. Light reactions - The part of photosynthesis that captures solar energy and stores it in chemicals.
