An experiment is created by a scientist to determine how fertiliser affects sugar cane height. Two fields receive fertilization, but the remaining two do not. Fertilizer Application serves as the experiment's control group.

Fertilizer Application is typically limited to irrigated plantations and varies by region and even by farmer. Fertilizers will work best if used between 12 and 24 months before and after the peak growing season. One year after planting, farmers typically spray 50 kg of urea and 50-100 kg of DAP per acre. Since Casuarina manufactures its own nitrogen with the aid of the bacterium Frankia, it does not require a significant amount of nitrogen fertiliser. In order to prevent this, it is advised to apply 11 kg of urea and 94 kg of superphosphate at moderate level.

How did flowers and fruits contribute to angiosperms becoming dominant land plants on earth?
Ainat [17]

Answer: The study, by Dr. Tim Brodribb and Dr. Taylor Field of the University of Tasmania and University of Tennessee, used plant physiology to reveal how flowering plants, including crops, were able to dominate land by evolving more efficient hydraulics, or 'leaf plumbing', to increase rates of photosynthesis.

Explanation: The reason for the success of this evolutionary step is that under relatively low atmospheric C02 conditions, like those existing at present, water transport efficiency and photosynthetic performance are tightly linked. Therefore adaptations that increase water transport will enhance maximum photosynthesis, exerting substantial evolutionary leverage over competing species.

The evolution of dense leaf venation in flowering plants, around 140-100 million years ago, was an event with profound significance for the continued evolution of flowering plants. This step provided a 'cretaceous productivity stimulus package' which reverberated across the biosphere and led to these plants playing the fundamental role in the biological and atmospheric functions of the earth.

Multicellular organisms use different types of cells to function not just one cell. If cells grew larger that cell would be more demanding.
