Plant Kingdom NEET MCQ for Biology with Answers

Plant Kingdom NEET MCQ: The plant kingdom comprises eukaryotic, autotrophic, photosynthetic, and non-motile creatures. According to R.H. Whittaker's classification of the plant kingdom in 1969, there are five main plant groups: Algae, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.

• The cellulose cell wall is present.
• except for certain aquatic species, non-motile.
• Reproduction is mostly sexual in nature.
• Different forms of algae (green, brown, and red algae), bryophytes, gymnosperms, and angiosperms are examples of organisms that survive by photosynthesis.

Q 2. Which of the below statements is false?

1. Pteridophytes reproduce by spores, following the cryptogamic principle,
2. Sporophytes are the primary plant body in pteridophytes,
3. Pteridophytes thrive in arid and chilly environments, such as mountains,
4. Pteridophytes contain specialized vascular tissues.

Answer: Option(3) is correct.

Explanation: Pteridophytes proliferate by spores like cryptogamae. Sporophyte is the primary plant structure of Pteridophytes. Pteridophytes can grow on sandy soils and occasionally in wet, shaded areas. There are specialized vascular tissues in pteridophytes.

Q 3. Which of the phrases regarding bryophytes below is false?

1. Bryophytes stop soil erosion,
2. They break down rocks to create rich soil,
3. They are utilized as fuel and as packing materials,
4. Food packaging materials are made of bryophytes since they don't absorb water.

Answer: Option(4) is correct.

Explanation: In order to stop soil erosion, bryophytes securely grip the soil. Bryophytes transform barren rocks into productive soil by breaking them down. Bryophytes are useful fuel sources and packaging materials. Bryophytes can't be utilized to store food since they are good water absorbers.

Q 4. What distinguishes liverworts from mosses in particular?

1. Mosses have vascular tissue that liverworts lack.
2. In contrast to liverworts, mosses have an intermediate stage known as protonema.
3. Mosses grow taller, whilst liverworts do not.
4. Sporophytes, specialized bodies found only in mosses, are missing in liverworts.

Answer: Option(2) is correct.

Explanation: Mosses develop into a stage known as protonema from spores before developing into thallus, which resembles leaves. In contrast, this transitional stage is not present in liverworts, therefore the spores grow into a thallus without a protonema.

Q 5. What statement regarding the haplontic life cycle is incorrect?

1. The predominant stage of its life cycle is the gametophyte stage.
2. Sporophytes live independently.
3. Spores are haploid in nature, and they divide during mitosis to generate gametophytes.
4. Zygote functions as a sporophyte.

Answer: Option(1) is correct.

Explanation: Gametophytes are the predominant stage in this life cycle, which is why the answer is (a). Sporophytes cannot live a life of their own free will. Spores are naturally haploid and develop into gametophytes during mitotic division. A zygote produces spores in the role of a sporophyte.

Q 6. Which one of the following is false?

1. The majority of leafy liverworts share structural similarities with mosses,
2. Liverworts have oil bodies that moss lacks,
3. Moses have lobes in their leaves but leafy liverworts lack,
4. Mosses have spirally organized leaves whereas leafy liverworts have leaves that develop in two or three rows.

Answer: Option(3) is correct.

Explanation: The majority of leafy liverworts have a structure that is similar to mosses. Oil bodies are present in leafy liverworts but not in mosses. Mosses lack lobes in their leaves, but leafy liverworts do. While the leaves of mosses are organized in spirals, those of leafy liverworts grow in two or three rows.

Q 7. Which statement concerning the haplo-diplontic life cycle is false?

1. In this life cycle, the sporophytic and gametophytic phases both have the same length of time.
2. The sporophytic and gametophytic stages are both multicellular and exist separately.
3. Pteridophytes and bryophytes both have this form of life cycle.
4. The life cycle of Ectocarpus is haploid.

Answer: Option(4) is correct.

Explanation: Both the sporophytic and gametophytic phases in this life cycle have several cells and their own autonomous existence. The primary periods of this life cycle vary. Bryophytes and Pteridophytes both have this type of life cycle. The haplo-diplontic and not haploid life cycle is seen in Ectocarpus.

Q 8. Which one of the following is false?

1. The haploid gametophyte is the predominant phase in bryophytes.
2. The main phase in Volvox is the haploid gametophyte.
3. In Spirogyra, the dominant phase is the diploid sporophyte.
4. In Pappaya, the dominant phase is the haploid gametophyte.

Answer: Option(3) is correct.

Explanation: In bryophytes and volvox, the haploid gametophyte phase predominates. Additionally, the haploid gametophyte is the dominant phase in Spirogyra. The haploid gametophyte is the predominant phase in Pappaya.

Q 9. Which of the following life cycles does Polysiphonia exhibit?

1. Diplontic,
2. Haplontic,
3. Trilontic,
4. Haplo-diplontic.

Answer: Option(2) is correct.

Explanation: The majority of algae are haplontic, whereas just a small percentage are diplontic. A handful of these algae, such as Polysiphonia, Ectocarpus, and kelps, have haplontic life cycles, in which the gametophyte phase dominates.

Q 10. Which of the following statements concerning the diplontic life cycle is false?

1. Sporophyte is the dominant phase,
2. All spermatophytes have a diplontic life cycle,
3. Sporophytes and gametophytes are mutually dependent,
4. Sporophyte feeds on the gametophyte.

Answer: Option(3) is correct.

Explanation: Sporophyte is the dominating phase. The life cycle of all spermatophytes is diplontic. Sporophyte is necessary for Gametophyte. Because sporophytes can do photosynthesis and have autonomous existence, they can also make their own nourishment.

Q 11. Which of the below statements is false?

1. Male and female gametes develop in sexual organs called gametophytes,
2. Male gametes are delivered to female gametes by means of water,
3. Male and female gametes further fuse to produce a zygotic structure that develops into an embryo,
4. This embryo continues to grow to form a haploidic structure known as sporophytes that bear spores.

Answer: Option(1) is correct.

Explanation: Gametes are created in sex organs known as gametangia. Gametophyte is the life cycle of sexual reproduction. It takes water for the male gametes to reach the female gametes. In order to create a zygotic structure, which eventually becomes an embryo, male and female gametes must fuse further. A haploid structure known as a sporophyte that bears spores grows from this embryo throughout time.

Q 12. Which of the following statements is false?

1. Male and female gametes fuse to generate zygotes, which are diploid in nature.
2. After zygotes undergo reduction division, sporophytes are formed.
3. The sporophyte goes through meiosis to create spores.
4. Spores sprout to create a new thallus.

Answer: Option(2) is correct.

Explanation: Zygote, which is diploid in nature, is created by the union of male and female gametes. After fusing, the zygote does not immediately proceed into reduction division. Instead, they develop a structure known as a sporophyte. To create spores, the sporophyte goes through meiosis. As they germinate, spores produce new thallus.

Q 13. What stage of a liverwort's life cycle is the most prevalent?

1. Diploid sporophyte
2. Diploid zygote
3. Haploid gametophyte
4. Diploid spores

Answer: Option (3) is correct.

Explanation: The haploid gametophyte stage of the liverwort's life cycle is the most prevalent. Gametophyte is the end product of the short-lived intermediate structures called diploid sporophyte, diploid zygote, and diploid spores.

Q 14. Which of the following statements concerning gymnosperm reproduction is false?

1. Microsporangium contains microsporocytes that go through meiosis to become microspores,
2. Microspores then go through reduction division to create microgametophytes,
3. Microgametophytes are also known as pollen grains,
4. Wind, water, and insects function as dispersion agents for pollination.

Answer: Option(1) is correct.

Explanation: Microsporocytes seen in microsporangia go through mitosis and not meiosis to become microspores. Microspores then divide by reduction to become microgametophytes. The term "microgametophyte" also refers to pollen grain. As dispersion agents for pollination, wind, water, and insects all play a role.

Q 15. Which of the following statements regarding gymnosperms is false?

1. Pollen grains produce a tube-like structure when they reach the female gametophyte, which carries sperm to the egg.
2. Gymnosperm fertilization is also known as siphonogamic.
3. Unlike angiosperm ovules, Gymnosperm ovules are not protected.
4. Every megaspore that is created after meiosis undergoes mitosis to form a female gametophyte.

Answer: Option(4) is correct.

Explanation: The pollen grains create a tube-like structure that acts as a conduit for sperm to get to the egg when they contact the female gametophyte.
