| Question | Answer |
|---|---|
| How was the description of diverse forms of life on Earth initially made? | Through observation using naked eyes, magnifying lenses, and microscopes. |
| What type of features were mainly described in early biology? | Gross structural features, both external and internal. |
| What else was recorded apart from structural features in early biological studies? | Observable and perceivable living phenomena. |
| What was biology mainly considered before experimental biology developed? | Natural history. |
| What are all angiosperms characterised by despite diversity in morphology? | Presence of roots, stems, leaves, flowers, and fruits. |
| Why are standard technical terms important in biology? | For successful classification and understanding of organisms. |
| What kinds of plant adaptations are mentioned? | Adaptations for habitats, protection, climbing, and storage. |
| What are the common parts seen when a weed is pulled out? | Roots, stems, leaves, flowers, and fruits. |
| What is the underground part of a flowering plant called? | Root system. |
| What is the above-ground part of a flowering plant called? | Shoot system. |
| In most dicotyledonous plants, what does elongation of the radicle form? | Primary root. |
| What do the branches of the primary root constitute? | Tap root system. |
| Which plants generally have a tap root system? | Dicotyledonous plants. |
| What replaces the primary root in monocotyledonous plants? | A large number of roots arising from the base of the stem. |
| What type of root system is seen in wheat? | Fibrous root system. |
| What are adventitious roots? | Roots arising from parts other than the radicle. |
| Name plants that show adventitious roots. | Grass, Monstera, and banyan tree. |
| What are the main functions of the root system? | Absorption of water and minerals, anchorage, food storage, and synthesis of plant growth regulators. |
| What are angiosperms characterised by despite their large diversity in morphology? | Presence of roots, stems, leaves, flowers, and fruits. |
| Why are standard technical terms and definitions important in biology? | For successful classification and understanding of plants and living organisms. |
| What kinds of plant adaptations are mentioned in the text? | Adaptations for habitats, protection, climbing, and storage. |
| Which parts are commonly seen in a weed when pulled out? | Roots, stems, leaves, flowers, and fruits. |
| What is the underground part of a flowering plant called? | Root system. |
| What is the above-ground portion of a flowering plant called? | Shoot system. |
| What does the direct elongation of the radicle form in dicotyledonous plants? | Primary root. |
| What are the branches of the primary root called? | Secondary, tertiary, and higher-order roots. |
| What do the primary root and its branches together constitute? | Tap root system. |
| Give an example of a plant with a tap root system. | Mustard plant. |
| What happens to the primary root in monocotyledonous plants? | It is short-lived and replaced by many roots arising from the stem base. |
| What type of root system is seen in wheat? | Fibrous root system. |
| What are adventitious roots? | Roots arising from plant parts other than the radicle. |
| Name plants that show adventitious roots. | Grass, Monstera, and banyan tree. |
| What are the main functions of the root system? | Absorption of water and minerals, anchorage, storage of reserve food, and synthesis of plant growth regulators. |
| From where do fibrous roots originate? | From the base of the stem. |
| Which root type develops directly from the radicle? | Primary root. |
| What protects the tender apex of the root as it moves through the soil? | Root cap. |
| What is the structure covering the apex of the root called? | Root cap. |
| Where is the region of meristematic activity located? | A few millimetres above the root cap. |
| What are the characteristics of cells in the meristematic region? | Very small, thin-walled, with dense protoplasm, and divide repeatedly. |
| Which region of the root is responsible for increase in root length? | Region of elongation. |
| What happens to cells in the region proximal to the meristematic region? | They undergo rapid elongation and enlargement. |
| What is the region proximal to the elongation zone called? | Region of maturation. |
| What structures are formed by epidermal cells in the region of maturation? | Root hairs. |
| What is the function of root hairs? | Absorption of water and minerals from the soil. |
| What is the stem? | The ascending part of the axis bearing branches, leaves, flowers, and fruits. |
| From which part of the embryo does the stem develop? | Plumule. |
| What are nodes? | Regions of the stem where leaves are borne. |
| What are internodes? | Portions of the stem between two nodes. |
| What types of buds are present on the stem? | Terminal and axillary buds. |
| What is the colour of young stems generally? | Green. |

This sample covers 50 of 272 Morphology of Flowering Plants flashcards. To review the complete set — every question in this chapter and every other NEET Biology chapter — study with our Web Flashcards or the Android NEET Flashcards app, both free.
Both are built around spaced repetition — a learning technique that resurfaces each flashcard right before you're about to forget it, so your revision time goes toward the questions you actually need to practice instead of rereading everything from the start. Studying this way, rather than a single read-through, is one of the most effective ways to improve long-term retention ahead of NEET-UG.
