In standard botanical nomenclature, Artocarpus integra is the scientific name of which common fruit tree?

Introduction / Context:
Scientific names are used in biology to identify organisms precisely and avoid confusion caused by different local names. They follow binomial nomenclature with a genus name and a specific epithet. This question asks you to connect the scientific name Artocarpus integra with its correct common name. Such questions are common in general knowledge and biology exams because they test both memory and understanding of plant diversity.

Given Data / Assumptions:

• The scientific name given is Artocarpus integra.
• The options are guava, pineapple, silver oak, and jackfruit.
• We assume a basic familiarity with common fruit trees and their botanical names.

Concept / Approach:
The genus Artocarpus includes several well known tropical trees, among them jackfruit and breadfruit. Guava, pineapple, and silver oak belong to completely different genera. Guava is known as Psidium guajava, pineapple is Ananas comosus, and silver oak is usually Grevillea robusta. Therefore, the approach is to match Artocarpus with the correct fruit species that belongs to this genus and then select that option.

Step-by-Step Solution:
Step 1: Recall that Artocarpus is a genus in the mulberry family that includes jackfruit and breadfruit. Step 2: Note that guava belongs to the genus Psidium, so it cannot match the given scientific name. Step 3: Recognize that pineapple is from the genus Ananas, again different from Artocarpus. Step 4: Understand that silver oak is an ornamental timber tree whose scientific name is Grevillea robusta and not Artocarpus integra. Step 5: Remember that jackfruit is commonly associated with the genus Artocarpus, and older or alternative names like Artocarpus integra or Artocarpus heterophyllus are linked with this tree in many texts. Step 6: Conclude that Artocarpus integra refers to the jackfruit tree.
Verification / Alternative check:
An alternative check is to think of the appearance and family traits of each plant. Jackfruit trees bear large, spiky fruits that hang from trunk and branches, a characteristic often discussed along with the genus Artocarpus in botany lessons. Guava, pineapple, and silver oak have entirely different morphology and are rarely mentioned under Artocarpus in textbooks. Standard lists of important fruit tree scientific names pair jackfruit with Artocarpus species, supporting the choice of jackfruit as the correct answer.

Why Other Options Are Wrong:
Guava: Its accepted scientific name is Psidium guajava, not Artocarpus integra, so this option is incorrect.
Pineapple: Pineapple is classified under the genus Ananas and commonly referred to as Ananas comosus, so it does not match the given scientific name.
Silver oak: This tree is usually called Grevillea robusta in scientific nomenclature and is neither a fruit tree like jackfruit nor a member of the genus Artocarpus.

Common Pitfalls:
Students sometimes guess based on which fruit they think is more common or more likely, instead of recalling exact scientific names. Another mistake is to confuse Artocarpus with other genera that have somewhat similar sounding names. To avoid such confusion, it is helpful to revise a short list of important crop and fruit species together with their botanical names before the exam.

Final Answer:
Artocarpus integra is the scientific name associated with the fruit tree known commonly as Jackfruit.
