BRAINCAKEThe Cell Cycle
Revision notes for The Cell Cycle in Edexcel Biology B (8BI0). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- ChromosomesIn a eukaryotic cell, the DNA in the nucleus is divided into a number of linear molecules.
- The Cell CycleThe cell cycle is the regular sequence of events by which a eukaryotic cell grows, copies its DNA and divides into two daughter cells.
- Control of the Cell CycleThe cell cycle is tightly controlled so that a cell only divides when it should, and only when it is ready.
- MitosisMitosis is the division of the nucleus that produces two daughter nuclei, each genetically identical to the parent nucleus and to each other, with…
- ProphaseProphase is the first stage of mitosis.
- MetaphaseMetaphase is the second stage of mitosis, following prophase.
- AnaphaseAnaphase is the third stage of mitosis, following metaphase.
- TelophaseTelophase is the final stage of mitosis.
- CytokinesisCytokinesis is the division of the cytoplasm to form two separate daughter cells.
- Asexual ReproductionAsexual reproduction is the production of new individuals from a single parent, without the fusion of gametes.
- SporulationSporulation (spore formation) is a type of asexual reproduction in which a parent organism produces large numbers of small, light reproductive cells…
- RegenerationRegeneration is the regrowth of lost or damaged body parts by mitosis followed by cell differentiation.
- BuddingBudding is a type of asexual reproduction in which a new individual develops as an outgrowth (a bud) from the body of the parent.
- Vegetative PropagationVegetative propagation is asexual reproduction in plants in which a new plant grows from a vegetative (non-reproductive) part of the parent, such as…
- Mitosis and Growth and RepairMitosis produces two daughter cells that are genetically identical to each other and to the parent cell, with the same number of chromosomes (46 in…
- Measuring GrowthGrowth is a permanent increase in size or mass, usually brought about by an increase in cell number and cell size.
- Growth PatternsWhen size is plotted against time, the shape of the curve shows the growth pattern of an organism.
- Growth in PlantsUnlike animals, in which cell division happens throughout the body, growth in plants is restricted to regions called meristems.
