1.
Scientifically, cereal grains are a kind of fruits called ___________
Correct Answer
D. Caryopsis
Explanation
Cereal grains are scientifically classified as caryopsis. Caryopsis is a type of fruit where the seed coat is fused with the ovary wall, resulting in a single-seeded fruit. In the case of cereal grains, the seed coat and ovary wall are fused tightly, enclosing the seed within a protective outer layer. This characteristic distinguishes cereal grains from other types of fruits like petiole, rhubarb, and eggplant, which have different structures and classifications.
2.
The outer and edible layer of fruits is called ___________
Correct Answer
B. Pericarp
Explanation
The correct answer is Pericarp. The pericarp refers to the outer and edible layer of fruits. It is composed of three layers: the epicarp (outermost layer), the mesocarp (middle layer), and the endocarp (innermost layer). The pericarp protects the seeds and helps in seed dispersal.
3.
How many layers have an ideal fruit?
Correct Answer
C. Three layers
Explanation
An ideal fruit typically has three layers. This can be observed in fruits like apples or oranges, where the outermost layer is the skin or peel, the middle layer is the fleshy part of the fruit, and the innermost layer is the core or seed cavity. These layers serve different purposes, such as protecting the fruit, containing the nutrients, and facilitating seed dispersal.
4.
Why is rhubarb referred to as a fruit?
Correct Answer
D. It is used to make sweet pies
Explanation
Rhubarb is referred to as a fruit because it is commonly used to make sweet pies. Although it is technically a vegetable, it is often treated as a fruit in culinary applications due to its tart flavor and its common use in desserts.
5.
Which of these is odd concerning the layers of the pericarp?
Correct Answer
B. Ectocarp
Explanation
The term "odd" in this context refers to something that is different or does not belong to a particular group. In this case, the layers of the pericarp are typically referred to as the mesocarp, endocarp, and exocarp. Ectocarp, on the other hand, is not commonly used to describe the layers of the pericarp. Therefore, it is considered odd in this context.
6.
Which group of fruits is the simplest compared to others?
Correct Answer
D. Apocarpous fruits
Explanation
Apocarpous fruits are the simplest compared to others because they are formed from a single carpel or pistil, which is the female reproductive structure of a flower. This means that each carpel develops into a separate fruit, resulting in multiple separate units within the fruit. In contrast, syncarpous fruits are formed from multiple fused carpels, aggregate fruits are formed from multiple separate carpels within a single flower, and acrocarpous fruits are formed from multiple carpels on different branches of the same plant. Therefore, apocarpous fruits have the least complexity in terms of their structure and formation.
7.
The types of simple fruit are the following except
Correct Answer
A. Teasel
Explanation
The question is asking for the type of simple fruit that is not included in the given options. The options provided are Cypsela, Capsule, and Achene. Teasel is not a type of simple fruit, so it is the correct answer.
8.
Berries are examples of which class of fruit?
Correct Answer
C. Aggregate fruits
Explanation
Aggregate fruits are formed from multiple ovaries of a single flower. In the case of berries, they develop from a single flower with multiple ovaries, each ovary producing a small fruit that fuses together to form a larger fruit. Examples of aggregate fruits include strawberries, raspberries, and blackberries.
9.
Generally, fruits disseminate seed through ___________main means.
Correct Answer
A. Four
Explanation
Fruits generally disseminate seeds through four main means. This suggests that there are four common ways in which fruits ensure the dispersal of their seeds. These means could include wind dispersal, animal dispersal, water dispersal, or self-dispersal. Each of these methods allows seeds to be carried away from the parent plant, increasing the chances of successful germination and growth in new locations.
10.
All of the following are produced from berries except
Correct Answer
A. Olive oil
Explanation
Olive oil is not produced from berries. It is produced from olives, which are a type of fruit. Black pepper, allspice, and paprika, on the other hand, are all produced from berries. Black pepper is made from the dried unripe fruit of the pepper plant. Allspice is made from the dried berries of the Pimenta dioica plant. Paprika is made from dried and ground peppers, which are a type of berry.
