| Question | Answer |
|---|---|
| What is the basic unit from which all organisms start life? | A single cell. |
| What are the two important characteristics of cells mentioned in the chapter? | Growth and reproduction. |
| How do cells reproduce? | By dividing into two daughter cells. |
| What allows a single cell to form a structure consisting of millions of cells? | Cycles of growth and division. |
| What is meant by the cell cycle? | The sequence of events by which a cell duplicates its genome, synthesises other cell constituents, and divides into two daughter cells. |
| Which three processes must occur in a coordinated way during cell division? | Cell division, DNA replication, and cell growth. |
| During which stage of the cell cycle does DNA synthesis occur? | During one specific stage of the cell cycle. |
| What controls the events of chromosome distribution during cell division? | Genetic control. |
| Name the two basic phases of the cell cycle. | Interphase and M Phase (Mitosis phase). |
| What does the M Phase represent? | The phase in which actual cell division or mitosis occurs. |
| What does interphase represent? | The phase between two successive M phases. |
| Approximately how long does a human cell take to complete one cell cycle? | About 24 hours. |
| How long can the cell cycle of yeast take? | About 90 minutes. |
| What percentage of the cell cycle is occupied by interphase? | More than 95%. |
| How long does cell division proper last in a human cell cycle? | About one hour. |
| What is karyokinesis? | Nuclear division corresponding to the separation of daughter chromosomes. |
| What is cytokinesis? | Division of the cytoplasm. |
| Why is interphase called the preparation phase? | Because the cell undergoes growth and DNA replication in an orderly manner. |
| Into which three phases is interphase divided? | G1 phase, S phase, and G2 phase. |
| What occurs during G1 phase? | The cell is metabolically active and continuously grows but does not replicate DNA. |
| What occurs during S phase? | DNA synthesis or replication takes place. |
| What happens to the DNA content during S phase? | It doubles from 2C to 4C. |
| Does chromosome number increase during S phase? | No, chromosome number remains the same. |
| What is the chromosome number after S phase if the cell was 2n in G1 phase? | It remains 2n. |
| What happens in animal cells during S phase besides DNA replication? | The centriole duplicates in the cytoplasm. |
| What occurs during G2 phase? | Proteins are synthesised in preparation for mitosis and cell growth continues. |
| What is the quiescent stage of the cell cycle called? | G0 stage. |
| What is characteristic of cells in G0 stage? | They remain metabolically active but do not proliferate. |
| Which animal cells generally do not exhibit division? | Heart cells. |
| In animals, mitotic division is mainly seen in which cells? | Diploid somatic cells. |
| Give an example where haploid cells divide by mitosis in animals. | Male honey bees. |
| Can plants show mitotic division in both haploid and diploid cells? | Yes. |
| Why is mitosis called equational division? | Because the number of chromosomes in parent and progeny cells remains the same. |
| Name the four stages of karyokinesis in mitosis. | Prophase, Metaphase, Anaphase, and Telophase. |
| Which is the first stage of karyokinesis in mitosis? | Prophase. |
| What marks the beginning of prophase? | Initiation of condensation of chromosomal material. |
| What happens to chromatin during prophase? | It condenses and becomes untangled. |
| What happens to centrosomes during prophase? | They move towards opposite poles of the cell. |
| What are asters? | Microtubules radiating from centrosomes. |
| What forms the mitotic apparatus? | Two asters together with spindle fibres. |
| What is the inactive stage entered by cells that no longer divide? | Quiescent stage (G0). |
| What is the condition of cells in G0 stage? | They remain metabolically active but no longer proliferate unless required. |
| In animals, mitotic cell division is generally seen in which type of cells? | Diploid somatic cells. |
| Give an example where haploid cells divide by mitosis in animals. | Male honey bees. |
| Can plants show mitotic divisions in both haploid and diploid cells? | Yes. |
| Why is mitosis called equational division? | Because the chromosome number remains the same in parent and progeny cells. |
| Which phase is considered the most dramatic period of the cell cycle? | M Phase. |
| What major process occurs during M Phase? | Major reorganisation of virtually all cell components. |
| What are the four stages of karyokinesis in mitosis? | Prophase, Metaphase, Anaphase, and Telophase. |
| Which stage is the first stage of karyokinesis in mitosis? | Prophase. |

This sample covers 50 of 225 Cell Cycle and Cell Division 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.
