Bryophytes are called amphibians of the plant kingdom because they need water for their reproductive processes.
2. In gymnosperms, the male reproductive structure is:
Answer:
Explanation:
In gymnosperms, male reproductive structures are microsporangia that produce pollen grains.
3. Ferns belong to the group:
Answer:
Explanation:
Ferns are vascular plants without seeds and belong to the division Pteridophyta.
4. The process of fusion of two gametes which are dissimilar in size is termed:
Answer:
Explanation:
Anisogamy refers to the fusion of two gametes that are dissimilar in size.
5. Which among the following is a seedless vascular plant?
Answer:
Explanation:
Ferns are vascular plants that do not produce seeds.
6. The dominant phase in the life cycle of a moss is:
Answer:
Explanation:
In mosses, the gametophyte is the dominant and independent phase of the life cycle.
7. Which group of plants shows alternation of generations?
Answer:
Explanation:
Alternation of generations is a feature observed in algae, bryophytes, and pteridophytes.
8. Vascular tissues are absent in:
Answer:
Explanation:
Mosses, being bryophytes, lack vascular tissues like xylem and phloem.
9. Which part of the pine tree produces pollen grains?
Answer:
Explanation:
In pine trees, the male cones produce pollen grains.
10. In angiosperms, the seeds are enclosed within:
Answer:
Explanation:
In angiosperms, the ovules develop into seeds which are enclosed within a fruit.
11. Cycas and Pinus differ in:
Answer:
Explanation:
Cycas and Pinus are both gymnosperms, but they differ in their reproductive structures, with neither having true flowers.
12. Which among the following is a characteristic feature of monocots?
Answer:
Explanation:
Monocots have scattered vascular bundles in the stem, unlike dicots.
13. The study of classification of organisms is called:
Answer:
Explanation:
Taxonomy deals with the classification, nomenclature, and identification of organisms.
14. Naming a plant is called
Answer:
Explanation:
Nomenclature refers to the process of assigning a name to an organism, following a set of rules and guidelines. In botanical context, the International Code of Nomenclature for algae, fungi, and plants (ICN) provides these rules.
15. Number of series in Polypetalae are
Answer:
Explanation:
In the Bentham and Hooker classification system, the subclass Polypetalae (under Dicotyledons) is divided into four series: Thalamiflorae, Disciflorae, Calyciflorae, and Corolliflorae based on the position and arrangement of floral organs.
16. Polyadelphous condition is found in
Answer:
Explanation:
In the family Leguminosae (specifically in the subfamily Faboideae), the stamens are often fused into bundles, leading to a polyadelphous condition where multiple stamens are united in more than two groups.
17. Synandrous condition is common in the family:
Answer:
Explanation:
In the family Cucurbitaceae, the stamens are often fused, leading to a synandrous condition where multiple stamens are united. This is a distinguishing characteristic of this family.
18. Indefinite stamens are characteristic of family:
Answer:
Explanation:
The family Malvaceae typically possesses flowers with indefinite or numerous stamens. The stamens are often fused into a tube around the style. This characteristic is one of the key features that differentiates Malvaceae from many other plant families.
19. Systematics deals with:
Answer:
Explanation:
Systematics encompasses the complete study of organisms, including their diversities and the relationships among them. It does involve classification, identification, and naming, but it primarily focuses on understanding the evolutionary relationships among organisms.
20. One of the best methods for understanding general relationships of plants is:
Answer:
Explanation:
Numerical taxonomy uses a large number of characteristics for the assessment of resemblances and differences. It employs mathematical techniques and computers, thereby providing an objective means of determining relationships between different plant taxa.
21. The chief merit of Bentham and Hooker’s classification is that:
Answer:
Explanation:
Bentham and Hooker’s system of classification, which they described in their work “Genera Plantarum,” was based on the actual examination of plant specimens. This meticulous approach added authenticity and reliability to their classification.
22. Linnaeus is credited with introducing:
Answer:
Explanation:
Carolus Linnaeus is renowned for developing the binomial system of nomenclature where each species is given a two-part name: the first name is the genus, and the second is the species.
