2. To transport water to the entire plant, especially the leaves where photosynthesis takes place. This is important because water is required for photosynthesis to take place.
3. Chlorophyll.
4. The palisade layer contains the most chloroplasts.
5. The function of the stomata is to allow gas exchange to facilitate photosynthesis. It also controls the rate of photosynthesis to regulate water use of the plant. Without it, plant would have severely hindered transpiration, causing the plant to die.
6. Chloroplasts are where photosynthesis takes place. Without chloroplasts, no synthesis would happen.
7. A leaf from a desert plant would likely have less stomata to conserve water content in the plant from evaporation due to environmental factors. This is because water escapes to the environment when stomata are open in plants. The contrary would be the case for plants in a tropical environment where water is more abundant and sunlight is more lacking.
The answer is B. Geology has shown a thin layer of iridium (a rare mineral on earth but found on asteroids and meteors) in the rock layers between the Cretaceous and Paleogene periods. Below this layer are numerous fossils of pterosaurs and dinosaurs, but above the layer are drastically few. The aftermath of asteroid impact is believed to have smothered most vegetation from earth which dinosaurs depended on as a source of food.
Answer:
The Muscular and Skeletal systems work together to help the body move and keep a shape.
The answer is D, photosynthesis and respiration.
—Evidence—
Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.
Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.
