Answer:
they are the place where cell respiration takes place
Explanation:
Cellular respiration is a series of metabolic reactions used by the cell to create energy (ATP), these reactions occur partially in the cytoplasm, but mostly in the mitochondria. On the other hand, vacuoles store water in plants and help give them structure, are the largest organelle in plant cells, and both plants and animals have them. Therefore the answer is, they are the place where cell respiration takes place.
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.
