What effect would increased carbon dioxide have on plants?

One of the most dramatic environmental changes today is the increase in carbon-dioxide levels in the atmosphere. We usually hear about it in connection with global warming, but that's not the only issue. What effect would increased carbon dioxide have on plants? If more trees are planted, would this stand to have any effect on a

Cells & Plant Seed Characteristics

Please help with the following problem. List the main reason why a cell is forced to divide due to cell growth. If a tall round seed plant is crossed with another plant. From the following information provided. Tall dominate, round dominant, and both are heterozygous. Draw the Punnett Square showing the first generation.

Cellular Respiration and Photosynthesis

Cellular respiration and photosynthesis co-exist as paired processes. Photosynthesis converts light energy into organic molecules such as carbohydrates. These molecules are picked up and utilized as fuel sources in organisms that employ cellular respiration for production of ATP and CO2. 1. Create a table comparing and contr

Photosynthesis

Discussion of modified leaves, stems, roots, flowers

Angiosperms (flowering plants) are the largest Phylum in the plant kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta). These plants have true roots, stems, leaves and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as t

Explain the processes of photosynthesis and cellular respiration.

Although it appears that Photosynthesis has preceded Cellular Respiration by billions of years, the processes share many structural features. 1. Create a table comparing and contrasting the two processes. Include in your comparison variables such as organism type, energy source, cellular location, substrates/reactants/prod

Biology 3-4

Please give detailed answers. 3. Charles Darwin once described a flower that produced nectar at the bottom of a tube 25 centimeters (10.5 inches) deep. He predicated that there must be a moth or other animal with a 25-centimeters-long tongue to match, and he was right. Such specilization almost certainly means that this pa

Biology 1-2

Please provide detailed explanations. 1. The desert tends to have two catagories of plants: small grasses of herbs, and shrubs or small trees. The grasses and herbs typically have fibrous roots. The shrubs and trees have taproots. What advantages can you think of for each type of root? How does each type of root allow f

Oaks are pondered in terms of breeding.

The oak makes potentially nutritious seeds (acorns) that contain very bitter-tasting tannins. If we could breed the tannin out of acorns, they might become a delicacy. Why do you suppose we have failed to domesticate oaks?

Plant Biology: Identification and Function

A Plant's Response to Gravity

According to the statolith hypothesis the cells farther away from the earth elongate while those near the earth do not. true or false and why?

Auxin was applied to a cut apical shoot of a bean plant...

I did an experiment in lab---Auxin was applied to a cut apical shoot of a bean plant. What results should I expect to find regarding lateral bud growth (decrase or increase) and also the number of lateral buds(increase or decrease). Also would the presence of auxin applied in this manner affect the vertical growth of the plant?

Experiment

Suppose an experiment is performed in which plant I is supplied with normal carbon doixide but with water that contains radioactive oxygen atom. Plant II is supplied with normal water but with carbon dioxide that contains radioactive oxygen atoms. Each plant is allowed to perform photosynthesis, and oxygen gas and sugars produce

Pasteur Effect, Glucose, Photosystem, and Other Short Answer Questions

1) Louis Pasteur (a French biochemist) investigated the metabolism of yeast which can survive under aerobic or anaerobic conditions. He observed that the yeast consumed sugar at a much faster rate under anaerobic conditions than it did under aerobic conditions. Explain this Pasteur effect. 2) If a plant is kept for many day

The ability to metabolize energy is confronted.

What are possible benefits and negative results we might expect if humans were genetically engineered to undergo photosynthesis? How do plant and animal cells metabolize energy in complimentary ways? Ideas are expressed.
