Case Study Questions on How Do Organisms Reproduce

Questions

Question 1:

Read the following and answer the questions given below:

All the reproductive methods of living organisms are broadly categorized into two types:
1. Asexual reproduction, and
2. Sexual reproduction.

Asexual reproduction involves the participation of a single parent without the formation of gametes, fertilisation and transfer of genetic material. This method is a common means of rapidly increasing offsprings under favourable conditions.

Read the above passage carefully and give the answer of the following questions:

Q 1. Name the type of fission that occurs in Leishmania and Plasmodium.

Q 2. Write one advantage of sexual mode of reproduction over asexual reproduction.

Q 3. Give reasons why:

(i) Colonies of yeast fail to multiply in water but multiply in sugar solution.

(ii) Rhizopus individuals do not grow on a dry slice of bread.

Name the filamentous structures a student could identify when he collected water from a pond that appeared dark green. How do these organisms multiply? Explain.

Answers

Leishmania – Binary fission Plasmodium – Multiple fission
Organisms produced by sexual reproduction have a greater survival rate as compared to asexual reproduction as more variations are produced which are important for the survival of species over time.
(i) Yeast cells fail to multiply in water because water does not provide any nutrition to yeast cells. Whereas in sugar solution, they multiply rapidly because sugar provides nutrition to carry out reproduction.
(ii) Rhizopus individuals do not grow on a dry slice of bread because microorganisms need optimum temperature and moisture to grow and if there is no moisture they will not grow.
Or
The filamentous structures are of Spirogyra.
Reproduction in Spirogyra: Spirogyra reproduces through fragmentation in which spirogyra filaments simply breaks into two or more fragments on maturation and each fragment then grows into a new spirogyra individual.

Frequently Asked Questions (FAQs) on How Do Organisms Reproduce Case Study Questions

Q1: What are case study questions for CBSE examinations?

A1: Case study questions in CBSE examinations typically involve scenarios or real-life examples, requiring students to apply their understanding of concepts to solve problems or analyze situations.

Q2: Why are case study questions important for understanding class 10 science chapters?

A2: Case study questions provide a practical context for students to apply theoretical knowledge to real-world situations, fostering deeper understanding and critical thinking skills.

Q3: How should students approach answering case study questions for CBSE?

A3: Students should carefully read the case study, identify the key issues or problems presented, analyze the information provided, apply relevant concepts and principles of chemical reactions and equations, and formulate well-supported solutions or responses.

Q4: Are there any resources available online for students to practice case study questions on class 10 science chapters for CBSE exams?

A4: Yes, several educational websites offer case study questions for CBSE students preparing for science examinations. We also offer a collection of case study questions for all classes and subject on our website. Visit our website to access these questions and enhance your learning experience. If you need more case study questions for your preparation, then you visit Physics Gurukul website.

Q5: How can students effectively prepare for case study questions on How Do Organisms Reproduce for CBSE exams?

A5: Effective preparation strategies include regular revision of concepts, solving practice questions, analyzing case studies from previous exams, seeking clarification on doubts, and consulting with teachers or peers for guidance and support.

Q6: How can teachers incorporate case study questions on How Do Organisms Reproduce class 10 science into classroom teaching?

A6: Teachers can integrate case studies into lesson plans, group discussions, or interactive activities to engage students in active learning, promote problem-solving skills, and facilitate a deeper understanding of How Do Organisms Reproduce.

Q7: Define tissue culture.

Ans. Tissue culture is the technique of growing cells or tissues in an artificial medium under controlled conditions in the
laboratory.

Q8: Why are sepals and petals called accessory structures in a flower?

A8: Sepals and petals help in the process of reproduction by providing protection to reproductive parts and to attract
pollinators.

Q9: What is the difference between bisexual and unisexual flowers?

A9: Bisexual flower contain both male and female reproductive parts whereas unisexual flowers contain only one of the
two reproductive parts.

Q10: Define pollination.

A10: Pollination is the transfer of pollen grains from opened anther to the receptive stigma of the carpel.

Q11: How does the germination of pollen grains occur?

A11: When pollen grains fall on the stigma, they absorb water and obtain sugars from the stigma. The inner wall of the pollen grain grows to form a pollen tube.

Q12: Why is DNA copying an essential part of the process of reproduction?

A12: The process of reproduction results in the production of offsprings which have the same characteristics as the parents. The progeny inherits the blue print of body design in the form of DNA. Therefore DNA copying is essential for reproduction.

Q13: How does binary fission differ from multiple fission?

A13: Binary fission of the parent cell divides into two, almost equal sized daughter cells; whereas multiple fission forms
several daughter cells each one of which forms a new individual.

Q14: How does reproduction help in providing stability of population of species?

A14: Reproduction helps in providing stability of population of species by maintaining the birth rate in proportion with the death rate.
