Chapter 37, Problem 9TYPSS
Summary Introduction
To review:
A hypothesis to explain that small seeds must be exposed to red light before they germinate, while large seeds do not depend on red light to germinate.
Introduction:
The photosynthesis is the most important process carried out in the plants in the presence of sunlight. In this process, the light energy is converted into chemical energy. It provides the plant with energy to carry out its

EXPERIMENT: INITIATION OF CALLUS AND CELL SUSPENSION IN SELECTED PLANTS
Please make a general introduction paragraph about this experiment.
Suitable hypothesis that will predict answers for the following:
A) what is the rate of germinating peas versus non-germinating peas.
B) what is the effect of temperature on germinating peas?
An experiment is conducted to determine the effect of classical music on the
growth rate of marigolds (flowers). Two groups of plants are grown from seed in
identical soil types, exposed to identical light conditions, and given the same
nutrients. Group A is in a quiet atmosphere. The plants in group B provided with
the same atmosphere, except that classical music is played for twelve hours daily
in this area. The scientist measures the plants in both groups each day and
records the data. In experimental design, Group A is known as.*

- Scenario: I planted a monggo seed and put red cellophane over one, and blue cellophane on the other in order to observe the plant growth. Question: a. How does the red color affect the seedlings of plants in terms of growth? b. How does the blue color affects the seedlings of plant in terms of growth?arrow_forwardYou have heard that singing to plants helps them grow and wonder if there is any validity to thisclaim. So, you conduct an experiment using numerous plants to determine if being exposed tomusic has any effect on their growth. 16. Which of the following is an appropriate sequence of steps to follow when conducting an experiment tostudy the effects of music on plant growth?a) theory → experiment → question → conclusion → observationsb) hypothesis → question → observations → conclusion → theoryc) question → observations → hypothesis → experiment → conclusiond) question → theory → observations → experiment → conclusion 17. For this experiment, what would be the independent variable?a) music b) plant growth c) amount of water d) type of plant 18. For this experiment, each of the following would be an example of a standardized variable, except _____ .a) exposure to light b) species of plant c) type of music d) plant stem lengtharrow_forwardJack and Jill are curious about the factors that affect plant growth. They perform several experiments using pea plants. (a) Identify one variable (other than water and sunlight) that could be tested. (b) Write a hypothesis using this variable. (c) Design an experiment to test this variable.arrow_forward
- Using scientific concepts and terms describe how the Bucket Orchid can temporarily “hold” onto the bee’s body while it glues the pollen sacs to the bees back. In other words, what type of plant “movement” (aka. response) would this most likely be described as? Please watch the YouTube link to answer the question. An Orchid’s Trap https://youtu.be/_uHJGdTgtXEarrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forwardPlant development is influenced by: A. quality of light only B. quality and quantity of light C. quality and duration of light D. quality, quantity and duration of lightarrow_forward
- Green fluorescent protein (GFP) can attach and mark other proteins with fluorescence, enabling scientists to see the presence of a particular protein. In an experiment to understand the molecular physiology behind the GA-induced seed germination, a GFP-tagged protein was observed to be moving from the cytoplasm into the nucleus of aleurone layer cells before the detection of alpha-amylase in the endosperm. Based on your knowledge, identify the possible protein(s) with which the GFP is attached in the given situation. Justify your answer.arrow_forwardYou hypothesise that plants will grow faster if they receive more fertiliser. Briefly explain how you would experimentally test this hypothesis by describing the experimental and control groups, independent-, dependent- and control variablesarrow_forwardWhat did Went's experiments with the gelatin block demonstrate? A. Plants cannot be induced to bend during growth unless they are exposed to an indirect source of light. B. Light induces the coleoptile to produce a diffusible substance that moves to the growing region of a plant where it stimulates cells to elongate. C. Gelatin can enhance the movement of a soluble factor from the growing region of a plant to the coleoptile where it accelerates growth. D. When a plant tip is removed from a growing plant, the plant acquires the ability to bend toward the lightarrow_forward

Explain.arrow_forwardImagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Unit 8 DQ Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree?
