B.Sc Semester-I (Backlog) | Botany: Microbial Diversity & Early Land Plants | Important Questions

[00:00:06]Hello degree students, let's see the question paper pattern for Sem One Back. So, the subject is Microbial Diversity and Early Line Plans, so let's take a look at this question paper pattern. So the paper part question paper was divided into two parts. Part A and Part B.

[00:00:25]In Part A, you have to answer any eight questions.

[00:00:29]12 questions are given. So each question carries four marks. Only eight questions should be written.

[00:00:35]Okay, move on to Part B. Part B has internal choice and all questions should be written. Next, move on to important questions from each unit. So, move on to the first unit.

[00:00:50]In the first unit, the first question is about the economic importance of bacteria. So, what should be done in this?

[00:00:57]First, what is bacteria? Introduction of bacteria? After writing its introduction, what is its economic importance? Like, its useful effects, harmful effects, and bacteria structure. Its nitrogen fixation, its decomposition. All these are Include all points. Move on to the second question.

[00:01:21]In the second question, describe the plant viral diseases and the control measures. So what should be written in the second question? First, write the common viral diseases of plants. Write it in a table format. After writing it in a table format, also mention the host plants. After mentioning it, also write its symptoms and control measures. Write a 10-point essay on control measures such as what are control measures, its uses, disease-free planting material, resistant varieties and vector control, wheat control.

[00:01:56]Next move on to the third question Describe the reproduction of bacteria Describe the reproduction of bacteria Write the first intro to this bacteria After writing the intro to bacteria write the types Write the types of reproduction Like sexual Asexual reproduction Now in which sexual does binary come Binary fission Fragmentation Spore formation Write these in detail step by step Next sexual This This Bacteria does not have sexual reproduction. It would be enough to write in detail about just genetic recombination, conjugation, transformation, and transduction.

[00:02:37]Next move on to the fourth question. Fourth question is about the cell structure of bacteria.

[00:02:43]After writing the same intro, write its structure.

[00:02:46]How does a cell structure look like? Now draw its structure and label it and describe each component. Just write it like a definition, drawing a diagram of each part of the bacterial cell wall, plasma membrane, capsule, cytoplasm, plasmids, mesosomes, and flagella.

[00:03:09]Next move on to the fifth question.

[00:03:13]This question about plant viral diseases and prevention has already been repeated in the second question. So if the second question is perfect, you can write the fifth question as well. Next move on to the sixth question, explain the economic importance of bacteria.

[00:03:26]This question also asks what bacteria is and then writes its economic importance. So same as first one next move on to sixth question describe the structure replication and transmission of viruses so first write what a virus actually is and then write the virus structure. Write its structure like types of viral symmetry.

[00:03:49]Next move on to replication, what is replication, write it step by step. Write this process in a flow chart and write it step by step. How to cover what points, how does it attach, how does it penetrate, how does it uncoat, how does it assemble and how does it release?

[00:04:06]Draw a diagram in detail and write it. Next move on to transmission, transmission of viruses.

[00:04:12]Now, transmission in viruses is transmission, what is spreading, how does it spread from one factor to another factor, what are the steps in it, like direct contact, vector, food and water transmission, mention all these in detail. The next eight questions explain the replication of replication in viruses, so the same is true of the seventh question, so if you write the seventh question perfectly, you can also answer the eighth question. Next move on to the second second unit Study of Algae. The first question in this study of algae is about the life cycle of Polysaponia. So, write about what life is like in the first polysaponia.
