How does the plant get all of the reactants needed for photosynthesis?

1 answer:

6 0

The reactants of photosynthesis are CO2 or Carbon Dioxide and H2O or Water.

Water is gains from the air or from the ground or from droplets on leaves from rain. If from the ground then the plants roots suck up the water and it travels up the plant via the capillary action to the leaves where the chloroplasts are. Other wise water enters via osmosis.

CO2 enters the plant via simple diffusion into the cells of the plant leaves and eventually into the chloroplasts.

The growth of plant seedlings is usually

zhenek [66]

Answer:

The correct answer is - A. phototropic and gravitropic.

Explanation:

A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.

The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

You are an oxygen molecule floating in the air near a rabbit about to pass into its nasal passageways. Tell the story of your ad

miskamm [114]

During cellular respiration, electrons are produced. The oxygen molecule accepts these electrons, then combines them with protons to make water. This outputs ATP, which is what the rabbit uses for energy. At the end of the process, carbon dioxide is released. From here, the carbon dioxide travels to one of the rabbit's favorite plants. This helps plants breathe. Sunlight penetrates the leaves of the plant, which are generating into sugar molecules within the chloroplast. The substance is known as chlorophyll. Electrons make the chemical process go more quickly. At the end, the plant releases oxygen back to the rabbit.

A doctor is studying a disease where the nucleus of a cell does not grow properly. What do you think would happen to the cells'

Drupady [299]

Answer:

The cell would fail to function. It would likely fail to properly replicate DNA properly or transcribe genes.

Explanation:

The nucleus holds the genetic information, the DNA. If the nucleus does not grow properly, the DNA might not fit or be properly organized inside. This would mean DNA replication could not proceed as normal, and the DNA might not even be able to fit inside the nucleus!

The cell would also struggle to properly transcribe the DNA if the nucleus is not fully formed. DNA acts as a template for mRNA transcription, which directs protein synthesis. The cell will very quickly die if there are inaccuracies in protein synthesis due to mRNA not being adequately synthesized.
