How did flowers and fruits contribute to angiosperms becoming dominant land plants on earth?

Biology

Ainat [17]2 years ago

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.

What is the water cycle and explain along with the process!​
Ann [662]

Answer:

The water cycle is a process in which water is lost from water bodies and then it again comes back to earth in form of rain. This is how I know it, but the explanation is correct.

Explanation:

See,

  • Water from water bodies evaporates and becomes water vapour due to heat
  • This then reaches high altitudes, where it condenses with dirt to create small droplets thingy
  • This then creates a cloud, which on correct saturation with water, makes it rains.

This cycle goes on continuously creating a cycle which is termed the water cycle.

Hope it helps

BYE

PLEASE HELPP!!!!
alexandr1967 [171]

Answer:

The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes.
