Based on cell function and homeostasis, explain why acid rain is so damaging to plants, such as the radish. How is it that some plants have developed a tolerance to low pH conditions?

I am doing an experiment lab report. Our question proposed is what will be the effect of the combination of earthworms and organic fertilizers on the growth of radish plants. It is expected that the average growth of radish plants that contain worms and organic fertilizer will have the greatest growth compared to radish plants grown with only organic fertilizer, only soil or only worms.

A. How can I put the experiment into a bigger context. (i.e.: Who cares?? Why does it matter?) After I get the results, how can I relate this to the world, and why these results should matter to people. I think it has to do with farming and the enviroment but I'm not sure how to put it into words.

Plant competition lab:

Objectives

In this lab, we will conduct an experiment to test both interspecific competition (between radish and collards plants) and intraspecific competition (radishes competing with radishes, or collards competing with collards). To determine if competition is occurring, we will measure survival, plant height, and aboveground biomass. Once the lab is completed and the data are collated from the entire class, you will then need to make graphs and answer the questions at the end of the lab.

Procedure:

Take 9 pots. Use only pots of the same shape (square or round); do not mix types.

Fill the pots with soil to within ½ inch of the top.

Thoroughly water the soil (until it runs out the bottom).

Add more soil if necessary to bring up the level to within ½ inch of the top.

Place the appropriate number of seeds on the soil surface. Be sure the seeds are evenly spaced. In the mixed species pots, intersperse the two species. See the table below for the nine different treatments.

Cover the seeds with a thin layer of soil. DO NOT water the soil again.

Label the pot with your name and the treatment on a piece of tape.

Before harvesting any plants in a pot, collect the following data:

Number of surviving radishes

Number of surviving collards

Average height of surviving radishes (cm)

Average height of surviving collards (cm)

2. After counting and measuring surviving plants, clip each plant where the stem meets the soil. If your pot is a mixed-species treatment, separate radishes from collards.

3a. For single-species treatments:

Weigh all plants within a pot for the total aboveground biomass (g)

Divide the total aboveground biomass by the number of plants that were alive in the pot, to calculate the mean aboveground biomass (g per plant)

3b. For mixed-species treatments:

Weigh all the plants of each species separately, for total aboveground biomass (g) for each species

For each species separately, divide the total aboveground biomass by the number of plants of that species that were alive in the pot, to calculate the mean aboveground biomass (g per plant, within a species)

Experimental Design

Single-species treatments (intraspecific competition tests)

4 collard seeds

16 collard seeds

36 collard seeds

4 radish seeds

16 radish seeds

36 radish seeds

Mixed-species treatments (interspecific competition tests)

2 collard + 2 radish seeds (4 total seeds)

8 collard + 8 radish seeds (16 total seeds)

18 collard + 18 radish seeds (36 total seeds)

Your mixed-species seeds should be arranged in a Latin square design, as shown below (the immediate neighbors of each seed are the other species).

--> Questions to consider about this lab

A. Hypotheses:

B. Which treatments are the controls and which are the experimental treatments?

C. What are the replicates in this experiment? How many are there for each treatment?

D. Do you see any inherent sources of bias in this experimental design?

E. Are there any problems with the experimental design that you can identify which might make interpretation of the data difficult or impossible?

2. There are two types of plants, C3 and C4. C3 plants use the Calvin Cycle to generate sugar. C4 plants use phosphoenol pyruvate to make malate and oxaloacetate which will eventually be used to make sugar. Both types of plants have stomatas (openings on leaves that can be opened and closed) for CO2 entry. In addition, water is also lost through the stomata. C3 plants are only able to synthesize sugar at relatively high CO2 levels because photosynthesis will stop when CO2 production from the mitochondria equals the use of CO2 in the chloroplasts. C4 plants are able to continue photosynthesis even at low CO2 levels. (1) Why are C4 plants able to survive in hot, dry conditions when C3 plants are not? (2) Plants can develop cancer but it is usually from an infection not from the ionizing rays of the sun. What part of the photosynthesis pathway do you think protects the plant form sun damage?
