Reproduction Flashcards
Asexual reproduction where a cell splits into two, only in prokaryotes
Binary Fission
Meiosis
Cell division into 4, only occurs in multicellular organisms, only for the production of haploid cells
Metaphase 1 in Meiosis
Everything in mitosis except its pairs of chromosomes that move rather than individual chromosomes
Asexual reproduction where a new organism grows out of another organism
Budding
Example of Fragmentation
Sea stars, flatworms, sponges
Telophase
Each of the cell’s structures are reconstructed, and the cells split
Budding
Asexual reproduction where a new organism grows out of another organism
Cell division into 2, for diploid somatic cells, for multi cellular organisms
Mitosis
Biggest differences between mitosis and meiosis
Mitosis splits into 2 and meiosis splits into 4, also for mitosis its only 2 pairs of chromosomes while in meiosis for the first round its a pair of a pair of chromosomes
Anaphase 1 in Meiosis
Same as mitosis
Anaphase
Motor proteins pull apart the connected chromosomes using microtubules and they are dragged to the end of each cell
Examples of budding
Hydra
Motor proteins pull apart the connected chromosomes using microtubules and they are dragged to the end of each cell
Anaphase
Examples of binary fission
Amoeba, bacteria
Phases of Mitosis
Prophase, Metaphase, Anaphase, Telophase
Binary Fission
Asexual reproduction where a cell splits into two, only in prokaryotes
Metaphase
Longest phase where the chromosomes attach to microtubules by motor proteins
2nd round of phases in meiosis
Same as first round, except no DNA is replicated
Phases of Meiosis
Same as mitosis, but happen twice
Fragmentation
Parent body intentionally breaks into pieces and each piece becomes a new organism
Regeneration
A part of an organism gets cut off, and a new organism grows from that part
Telophase
Each of the cell’s structures are reconstructed, and the cells split
Mitosis
Cell division into 2, for diploid somatic cells, for multi cellular organisms
Telophase 1 in Meiosis
Same as mitosis
Phase where chromatin coils up to create chromosomes, the nuclear envelope disintegrates, and centrosomes create microtubules
Prophase
Cell division into 4, only occurs in multicellular organisms, only for the production of haploid cells
Meiosis
Longest phase where the chromosomes attach to microtubules by motor proteins
Metaphase
What happens before mitosis
Centrosomes duplicate + cell cycle
A part of an organism gets cut off, and a new organism grows from that part
Regeneration
Binary fission vs Mitosis
Mitosis is in eukaryotes while binary fission is in prokaryotes and binary fission is for entire reproduction
Prophase 1 in Meiosis
Everything in mitosis + crossing over and recombination
Prophase
Chromatin coils up to create chromosomes, the nuclear envelope disintegrates, and centrosomes create microtubules
Example of regeneration
Hydra
