Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants
The correct answer is C
hope this helps have a good day :)
Answer:
Pteridophytes are vascular plants but they do not produce flowers and seeds which mean their source of reproduction is unknown or hidden.
On the contrary, Spermatophytes as the name indicates, are seed bearing plants. They produced seeds and flowers. Examples are flowering plants, cactus, leather flower, buttercup and may more.

Answer:
Myelination
Explanation:
The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).
The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.
If all other resources are in adequate supply, then the light intensity will increase the rate of photosynthesis. To balance it out, other things then usually start becoming short in supply, so things often don't change.
