Answer: (d) Lack of multicellular organization
Explanation: Kingdom Plantae includes multicellular organisms with well-defined tissues and organs.
Answer: (b) Moss
Explanation: Moss belongs to the Bryophyta group, which lacks vascular tissues (xylem and phloem).
Answer: (b) Flowers and fruits
Explanation: Gymnosperms produce seeds but do not form flowers or fruits, unlike angiosperms.
Answer: (b) Spores
Explanation: Pteridophytes (like ferns) reproduce via spores and do not produce seeds.
Answer: (b) Bryophyta
Explanation: Bryophytes require water for reproduction and live in moist environments, hence they are called “amphibians of the plant kingdom.”
Answer: (b) Water and minerals
Explanation: Xylem is responsible for conducting water and minerals from roots to the rest of the plant.
Answer: (c) Flowers and fruits
Explanation: Angiosperms produce flowers and fruits containing seeds, distinguishing them from gymnosperms.
Answer: (c) Rice
Explanation: Monocots like rice have a single cotyledon in their seeds, parallel leaf venation, and scattered vascular bundles.
Answer: (c) Angiosperms
Explanation: Double fertilization occurs in angiosperms where one sperm fertilizes the egg, and another fuses with polar nuclei to form endosperm
Answer: (d) Angiosperms
Explanation: Angiosperms are also called flowering plants because they bear flowers that develop into fruits.
Answer: (b) Gametophyte
Explanation: In bryophytes, the gametophyte is dominant and photosynthetic, while the sporophyte is dependent on it.
Answer: (b) Thallophyta
Explanation: Algae belong to Thallophyta, which includes simple, autotrophic, non-vascular plants.
Answer: (b) Cone
Explanation: Gymnosperms reproduce through cones (male and female), which produce pollen and ovules.
Answer: (c) Roots, stems, and leaves
Explanation: Pteridophytes are the first group of plants to show differentiation into true roots, stems, and leaves.
Answer: (a) Diploid and haploid phases
Explanation: Plants alternate between a diploid sporophyte and a haploid gametophyte phase in their life cycle.
Answer: (b) Cactus
Explanation: Xerophytes like cactus are adapted to survive in dry conditions with modifications like thick cuticles and reduced leaves.
Answer: (b) Transport of food
Explanation: Phloem transports food (mainly sucrose) from leaves to other parts of the plant.
Answer: (c) Pine
Explanation: Pine is a gymnosperm, characterized by needle-like leaves and cone-bearing reproductive structures.
Answer: (c) Spirogyra
Explanation: Spirogyra reproduces asexually through fragmentation, where its filaments break into pieces that grow into new individuals.
Answer: (b) Pteridophyta
Explanation: In pteridophytes, the sporophyte is dominant and independent, while the gametophyte is small and short-lived.
Answer: (d) Thallophytes
Explanation: Thallophytes (including algae) are the most primitive plants with a simple, undifferentiated body structure.
Answer: (c) Xylem
Explanation: Xylem transports water and dissolved minerals from roots to other parts of the plant.
Answer: (b) Naked
Explanation: Gymnosperms produce naked seeds that are not enclosed within fruits.
Answer: (b) Pteridophyta
Explanation: Pteridophytes have vascular tissues (xylem and phloem) but reproduce through spores, not seeds.
Answer: (c) Sunflower
Explanation: Sunflower is an angiosperm because it produces flowers and seeds enclosed within fruits.
Answer: (b) Sporophyte
Explanation: In pteridophytes, the diploid sporophyte is the dominant and independent phase.
Answer: (b) Pinus
Explanation: Heterosporous plants like Pinus produce two types of spores—microspores (male) and megaspores (female).
Answer: (b) Absorb water and minerals
Explanation: Root hairs increase the surface area for absorption of water and minerals from the soil.
Answer: (b) Haploid (n)
Explanation: Spores are haploid as they are produced through meiosis in the sporophyte generation.
Answer: (b) Seed coat
Explanation: The seed coat is a protective layer that covers and safeguards the embryo.
