Answer:
During reproduction plant might experience absence of pollinators or presence of low temperature
Explanation:
Following can be the problems a plant might encounter during reproduction
- Presence of Low temperature for long time: Due to presence of low temperature during the reproduction of plants for long period of time it will break its dormancy and freeze the blossom or developing fruit
- Absence of pollinators: As e know pollinators play a vital role in reproduction. In the absence of Pollinators (i.e., beans) plants are not able to exchange the nectar carrying
It can be called<span> a draw, a wash or a gulch</span>
This was a major breakthrough in geology because it meant that sedimentary strata in diverse parts of a country or area could be correlated as belonging to the same formation which means they were formed at the same time historically so helped to put them in the correct sequence. If these strata contained valuable minerals like coal then it could aid in the search for coal. This helped William 'Strata' Smith in England to create his first geological map in the world of a whole country.

Explanation:
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
