To determine: Whether the “teeth” along the edges of red maple (Acer rubrum) leaves varies from north to south.
Concept Introduction:
To determine: Whether the data suggest that these differences are due to climatic or genetic differences.
Concept Introduction: Genetic variation is caused due to the genetic factors that are transferred in families. Topography of the soil influences the growth and development of plant. Genetic variation may cause the change in reproductive ability, habit specialization, plant–insect interaction, and generation time. The climatic condition includes the rainfall, water, light, humidity, air, and wind. These are considered as abiotic components.

- a botanist wants to see how different colored light waves influence the growth of pea plants. she puts the same number of seeds into three identical pots with the same kind and amount of soil. she then gives them the same amount of water every 3 days for the length of the experiment. one pot is placed into a dark windowless closet. another part is left on the window sill, and the third is placed under a lamp with a green bulb. she records the height of each plant every day for 3 months what is the independent variable in this experiment.arrow_forwardA team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 μmol, and Groups 3 and 4 were exposed to 500 μmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group 1(200 μmol, no P) Group 2(200 μmol, + P) Group 3 (500 μmol, no P) Group 4 (500 μmol + P) Average Dry weight (g) 0.8 1.1 1.5 6.2 Describe the effects of light and phosphorous on the growth of the plants in this study. Explain how the metabolic processes associated with the plant kingdom likely influenced these results.arrow_forwardFigure 21.6 The Svalbard seed vault is located on Spitsbergen island in Norway, which has an arctic climate.

In this experiment you had two treatments - one with soil bacteria present, the other with soil bacteria absent. To determine how soil bacteria affected plant growth, you then measured plant height after 1 month. You find that plants grow taller in the treatment with soil bacteria compared to the treatment with no soil bacteria.

- Imagine you sampled a field that is 60 m X 130 m to see how many white clover plants are growing there. You used the same size quadrant as used in the video (0.5 m X 0.5 m). Please remember that m stands for meters. You took 10 quadrant samples and found a total of 8 white clover plants.arrow_forwardThey started to read books, surf the internet and study researches on the effect of music to plant growth, Members from the group continued to formulate their respective hypotheses. They went on performing a simple experiment. The group selected two San Francisco plants of similar size planted on the sanme type of soil and kind of pots. Both plants were healthy. Each plant were placed in separate rooms with a window exposed to full sunlight and were watered with equal amounts every day. They measured the height of the plants. Once a day, they played classical music on room 1 for about one hour while leaving room 2 with no music played. Over a period of two weeks, they noted significant differences in each plant's growth. Multiple Choice: Write the letter of your answer before the number. What was the problem in the Grade 7-Rizal's experiment? Which San Francisco plant is taller?

- Doug Schemske is a biologist who studies plants from around the world. Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments. Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location. To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…arrow_forwardYou have been asked to design a drought-resistant plant that will grown in the special areas, a large region in southeastern Alberta that has cyclical drought.

Three groups of plants are grown in the same location in a greenhouse, each receiving the same amount of sunlight and water every day. The scientist measures the length of the roots for each plant every day. The scientist then calculates the mean for each group for five days. The results are shown in the following table.
