What pteridophta reproductive structures look like and what are those structure called.
what are seedless vascular plants reproductive structures called and what do they look like.
Describe how xylem and phloem function with regards to movement of water, minerals etc from roots to leaves in a transpiring plant and from leaves or source organ to sink organs.
Structural modifications to the orchid from the angiosperm Monocot family to leaves, roots, stems, or flowers that result in adaptive functions.
The selective permeability of a plant cell's plasma membrane controls the movement of solutes between the cell and the extracellular solution.
You have a goldfish pond in your back yard. It is stocked with goldfish and water plants. There are aerobic bacteria in the pond also. What is happening with the oxygen and carbon dioxide levels in
When comparing nodule specific nitrogenase activities in control and nitrate treated plants at 20% oxygen, why is it necessary to express nitrogenase activity per gram fresh weight of nodule tissue?
How would animal life be affected by this atmospheric change? Explain why in terms of your knowledge of cellular respiration.
Name and describe the major reactions and sites of reactions of photosynthesis.
If photosynthesis is to occur at all, the plant must be able to intercept light. The better a plant is in intercepting the light, the greater opportunities the plant has to produce food.
Would you help me with the following question? Provide a description of common plant photosynthetic pigments you might expect to find in cabbage. Why do plants have photosynthetic pigments.
This solution describes the processes of photosynthesis and cellular respiration, as well as how they are linked between plants and animals based on the reactants.
If all oxygen in seawater comes either from exchange with the atmosphere or from photosynthesis by phytoplankton in the euphotic zone, how do you explain that there is sufficient dissolved oxygen th
What colors of the visible light spectrum are absorbed by black objects? White objects? How about the red leaf plant Coleus? What other plant leaf colors exist (besides green) and what colors do the
What environmental factors simultaneously limit photosynthesis? Explain the concept of saturation by applying conditions under which photosynthesis is not limited.
What are some short-term and long-term advantages and disadvantages of genetically changing plant physiological processes, such as photosynthesis and metabolism? Do you think it would affect other p
Why are enzymes critical to the function of cells? That is, why not simply let chemical reactions occur without interference.
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
Plants absorb light energy using special molecules called photosynthetic pigments (predominantly chlorophylls). These pigments absorb most of the visible light except for wavelengths in the green pa
Why do leaves of deciduous trees and shrubs in temperate regions change color in the fall? What is involved in this process? What factors may further influence this change, such as street lights, ad
Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata
A plant with chromosomal type xx pollinates with another plant that has chromosomal type XX. In the resulting seed, what chromosomal type/types of embryo and endosperm can be expected? Ideas are exp
Determine the minimum number of mutations that would be required to explain the observed sequences based on each of the two trees that you drew in part (b).
Do indoor plants create oxygen as a by-product the same way in which outdoor plants do (through photosynthesis).
