Natali5045456 [20]

Answer:

The suitable words will be -

  1. Red and Blue  
  2. Green

Explanation:

  • Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the light spectrum causes the least plant growth. Assume that all conditions other than the color of the light are the same for each seed as it grows: the soil, moisture, viability of the seed, etc. State your hypothesis on your lab worksheet. Example: If a plant is grown under Red and Blue color of light then the plant will grow well. However, if the plant is grown under Green color light then the plant will not grow well.
  • All the VIBGYOR color is mixed all together and forms the White color. Plants are green because chlorophyll reflects the green light and absorbs the other light spectrums. If the Blue light spectrum is absorbed then the plant will grow the most and if the Greenlight spectrum is absorbed then the plant will grow the least.

<h2>Diffuse co-evolution </h2>

Explanation:

The term ‘diffuse co-evolution’ was given by Janzen in 1980 to describe the idea that selection on traits often reflects the actions of many community members, as opposed to pairwise interactions between species

The idea was further clarified by Gould in 1988 by focusing on a variety of ecological and genetic mechanisms that might lead to diffuse co-evolution in response to selection from multiple species

Diffuse co-evolution as a whole can be defined as when selection imposed reciprocally by one species on another is dependent on the presence or absence of other species

In the given example panic grass can live only when the fungus protuberata is present and for Curvularia protuberata to colonize Curvularia thermal tolerance virus must be present so there is a web of multiple species where one species is dependent on other species and that other species in turn is dependent on different species hence referred to as diffuse co-evolution

What is photosynthesis? Mention function of any one plant part involved in this process.
german

Answer:

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
