Which plant tissue is responsible for the transport of water and minerals?

Xylem is responsible for the transport of water and minerals from the roots to other parts of the plant. This follows from NCERT principle where relation explains outcome clearly for students.

Which of the following does NOT occur in interphase?

Chromosome segregation occurs during mitosis, whereas interphase is mainly for growth, DNA replication, and preparation for division. This follows from NCERT principle where relation explains outcome clearly for students.

Which of the following statements about endemic species is incorrect?

Endemic species are restricted to specific geographic locations and are not widespread across multiple continents. This follows from NCERT principle where relation explains outcome clearly for students.

Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.

Which ecosystem in India has the highest number of endemic species?

The Western Ghats have the highest number of endemic species in India, making them a biodiversity hotspot. This follows from NCERT principle where relation explains outcome clearly for students.

What is the primary function of the bacterial capsule?

The bacterial capsule provides protection against phagocytosis by host immune lls. This follows from NCERT principle where relation explains outcome clearly for students.

Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.

Which of the following statements about cytokinins is correct?

Cytokinins are produced in root tips and promote ll division and shoot growth. They delay, not promote, leaf senescence. This follows from NCERT principle where relation explains outcome clearly for students.

Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.

Which of the following statements about transcription is correct?

In **eukaryotes**, transcription occurs in the **nucleus**, while in prokaryotes, it occurs in the **cytoplasm**. This follows from NCERT principle where relation explains outcome clearly for students.

Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.

Which of the following is an incorrect statement about linked genes?

Linked genes do not follow the Law of Independent Assortment as they are inherited together unless crossing over occurs. This follows from NCERT principle where relation explains outcome clearly for students.

Which of the following statements about seeds is correct?

The radicle develops into the root, while the plumule forms the shoot. This follows from NCERT principle where relation explains outcome clearly for students.

Which of the following statements about the ll wall is correct?

In plant lls, the ll wall is primarily composed of llulose, providing structural support. This follows from NCERT principle where relation explains outcome clearly for students.

Which stage of meiosis involves crossing over?

During Prophase I, homologous chromosomes undergo crossing over, increasing genetic diversity. This follows from NCERT principle where relation explains outcome clearly for students.

Which of the following is incorrect about translation?

Translation does **not** produce **DNA from RNA**; it converts **mRNA into protein**. This follows from NCERT principle where relation explains outcome clearly for students.
