    Chapter 11 “Mass Media Effects” Review and Reaction posted

    Please pay attention. This chapter is very long and important attention to the title of the chapter (depend by the textbook edition that may be different).

    This chapter is very important and long( lots of information to learn). Read it and will be discuss it in the class and write a page and half single space page and a paragraph of learning and reaction (total two pages 1000).

    Photosynthesis Complete Explanation (Class 10 ICSE)

    Photosynthesis is the process by which green plants make their own food using sunlight, carbon dioxide, and water in the presence of chlorophyll.

    Balanced Chemical Equation

    6CO_2 + 6H_2O xrightarrow[text{chlorophyll}]{text{sunlight}} C_6H_{12}O_6 + 6O_2

    This means:

    • Carbon dioxide + Water Glucose + Oxygen

    Steps of Photosynthesis

    1. Light Reaction (Occurs in chloroplasts)

    • Sunlight is absorbed by chlorophyll
    • Water splits into:
      • Oxygen (released into air)
      • Hydrogen ions and electrons
    • Energy is stored as ATP

    2. Dark Reaction (Calvin Cycle)

    • Takes place in the stroma of chloroplast
    • Carbon dioxide combines with hydrogen to form glucose
    • Does not need sunlight directly

    Factors Affecting the Rate of Photosynthesis

    1. Light Intensity

    • More light faster photosynthesis (up to a limit)
    • Very high light can damage chlorophyll

    2. Carbon Dioxide Concentration

    • Increased CO increases rate (till saturation point)

    3. Temperature

    • Optimum: 25C 35C
    • Low temp slows enzymes
    • High temp enzymes denature

    4. Water

    • Shortage reduces photosynthesis
    • Causes stomata to close less CO intake

    5. Chlorophyll Content

    • More chlorophyll higher rate
    • Less chlorophyll reduced photosynthesis

    Important Definitions

    • Chlorophyll: Green pigment that absorbs sunlight
    • Stomata: Tiny pores for gas exchange
    • Glucose: Food produced by plants
    • Photolysis: Splitting of water using light

    Quick Revision

    • Photosynthesis = Food-making process in plants
    • Requires: Sunlight, CO, Water, Chlorophyll
    • Produces: Glucose + Oxygen
    • Happens in chloroplasts
    • Two stages: Light reaction & Dark reaction

    Practice Questions

    1. Define photosynthesis.
    2. Write the balanced equation of photosynthesis.
    3. Name two stages of photosynthesis.
    4. What is the role of chlorophyll?
    5. How does temperature affect photosynthesis?

  • discussion and refelction

    Applied behavior analysis emphasizes not only the effectiveness of interventions but also the importance of client participation and acceptability. Two key concepts in this area are assent (obtaining ongoing agreement from clients to participate in interventions or research) and social validity (evaluating whether goals, procedures, and outcomes are meaningful and acceptable to the client and stakeholders).

    For this discussion:

    1. Summarize what you see as the main differences between assent and social validity.
    2. Reflect on why each is important in research and practice.
    3. Provide a concrete example (from your own experience, coursework, or a hypothetical scenario) of how you would assess either assent or social validity in a way that protects client dignity and improves the quality of the research.

    Note: Focus on research and applied settings in behavior analysis.

  • search, and review 2 journal articles.

    a. Read Chapter eleven and summarise the chapter in one paragraph (Paragraph 1).

    b. Read a journal article about Personality and stress. Show in paragraph 2 how personality and stress interact to affect a persons well-being.

    c. Read one journal article about Stress and health. Show in paragraph 3 how stress affects and complicates any medical illness.

    1.Each report must be written in a separate paragraph

    2.Your paper must therefore have at least three paragraphs

    3.On top of each paragraph, you must write the journal reference.
