OVERVIEW In this experiment you will work with seeds that are living but dormant. A seed contains an embryo plant and a food supply surrounded by a seed coat. When the necessary conditions are met, germination occurs and the rate of cellular respiration greatly increases. In this lab you will: 1. Measure oxygen consumption

The effects of pH and temperature were studied for an enzyme-catalyzed reaction. The following results were obtained. a. How do (1) temperature and (2) pH affect the activity of this enzyme? lii your answer, include a discussion of the relationship between the structure and the function of this enzyme, as well as a discussi
This job answers these questions: 1. Two possible end products of fermentation are ____________ as is produced by our muscle cell under anaerobic conditions and ____________ by yeast under anaerobic conditions. 2. If C4 photosynthesis prevents photorespiration, why haven't all plants evolved to use the C4 pathway? a.
A scientist gradually increases the amount of Carbon Dioxide available to a plant.The plant's rate of photosynthesis increases at first, but then levels off. What else might the plant need to further increase it's rate of photosynthesis?
Name the end sugar product of plant food production.
Name the reaction in which plants require no light.
The process of food production in plants involves the release of what gas?
The process of food production in plants requires the input of _______ and water?
What cell part is the site for food production in plants?
In a lab when the tubes are wrapped with aluminium foil to eliminate the light source, which reaction is taking place?
Molecules of green pigment are called?
Suppose an experiement is performed which included Plant I supplied with normal carbon dioxide but with water that contains radioactive oxygen atoms. Plant II is supplied with normal water but with carbon dioxide that contains radioactive oxygen atoms. Each plant is allow to perform photosynthesis and the oxygen gas and sugars
This is for review only. Thank you. A hormone induced dropping of leaves, flowers, fruits or other parts of a plant is: A. Abscission B. Petiolaria C. Assimilation D.Pollination A seed leaf is a: A. seed B. cotyledeon C. monocot D. leaf primordia The fusion of a sperm nucleus with the egg nucleus and the fusion
Which Division contains members once used to scrub pots and pans? a. Division Sphenophyta b. Division Psilophyta c. Division Lycophyta d. Division Pterophyta Which of the following has "scale-like" leaves and photosynthetic stems? a. club mosses b. ferns c. horsetails d. hornworts Which of the following describes a
Sporophytes a. develop from spores and produce gametes. B. are the dominant phase in the life cycle of most terrestrial plants. C. are the haploid stage of the plant life cycle. D. reproduce sexually. In which of the following groups is the sporophyte dependent on the gametophyte? A. Ferns B. Bryophyte
-- Define and briefly discuss both siphonogamy and the seed. -- Which do you think came first? I have a good start on the definitions, but please reword or (briefly) add to them to make them complete: A seed is: a fertilized, integumented, (Sterile covering/coating. Provided by diploid parent) undehiscing (non-splitting. Does
There are actually three questions here, all dealing with Rhynia (Rhynia is known by two names, the diploid life cycle "Rhynia major", and the haploid life cycle "Rhynia gwynne-vaughanii"). I thought it would be a good idea to put these 3 questions together because they all deal with the same general ideas. 1) HOW HAS THE FER
Do indoor plants create oxygen as a by-product the same way in which outdoor plants do (through photosynthesis)? Is there any advantage to having plants in your house, other than for decor? Does the oxygen provide any added benefit? Does is provide cleaner air to breath? These questions are encompassed.
A question that comes to mind is how greenhouses work. The light is filtered through windows, but the heat and resulting oxygen is confined to the greenhouse? I believe that this situation does have a positive effect on growth.
I think that the photosynthesis reaction is a very efficient system. I wonder if there is a way to see if more intense light actually helps the plant grow better, or if just being in sunlight under any intensity yields the same amount of work.
We are given the following five sequence: Taxon 1, Taxon 2, Taxon 3, Taxon 4, Taxon 5 TGCCAA, GGACAA, TGTCAA, TGTCAT, GGACAT a) In general, how many unrooted trees are there relation five taxa? b) Draw the following two trees. the first one has taxa 2 and 5 as sister taxa and taxa 1 and 3 as sister taxa. the second one
If a Midwest winter will see plants, lawns, flowers and the like dying, how does photosynthesis play a part here? This job correlates between photosynthesis and the greenness.
Approximately 2.2 billion years ago Earth's atmosphere experienced a rapid accumulation of Oxygen. Photosynthesis played an intricate role in the evolution of the Earth's early atmosphere. Describe in detail one of the factors influencing the rate at which photosynthesis occurs, and explain how it effects the rate.
What would you expect the rate of photosynthesis curve to look like and why?
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 expressed.
What are two characteristics unique to angiosperm reproduction? And how can you tell that grass flowers are wind pollinated rather than insect pollinated?
Need assistance comparing chemiosmosis in cell respiration and photosynthesis using the attached figures from pages 100 of my text and pg 118 to fill out the enclosed chart. Looking at the diagram I wasn't even sure where to start. Need assistance filling out the chart. See attached files (Chart, pg 100, pg 118)
Review of Photosysthesis as it relates to light Dependent Reaction and Independent Reaction. Using figure 7.11 for review to fill in the blanks in the chart. for blanks A through V. See attached files.
If I have a bumper sticker that says "Have I thanked a green plant today" - How would I interpret this in regards to photosynthesis?
Why is ribulose bisphosphates one of the most common organic molecules in living things?
