ASEXUAL REPRODUCTION AND MITOSIS Flashcards
ASEXUAL REPRODUCTION INVOLVES (…)
MITOSIS
AN ORDINARY CELL CAN MAKE A NEW CELL SIPLY BY DIVING IN TWO, BOTH ARE GENETICALLY IDENTICAL TO THE ORIGINAL CELL, THEY BPTH CONTAIN THE SAME GENETIC INFORMATION, ITS DIVISION IS CALLED (…)
MITOSIS
ASEXUAL REPRODUCTION INVOLVES ONLY (…)
ONE PARENT, THE OFFSPRING HAVE IDENTICAL GENES TO THE ^PARENT, SO THERES NO VARIATION BETWEEN PARENT AND OFFSPRING
WHAT IS MITOSIS
WHEN A CELL REPRODUICES ITSELF BY SPLITTING TO FORM TWO CELLS WITH IDENTICAL SETS OF CHROMOSOMES
IF THE CELL GETS A SIGNAL TO DIVIDE, IT NEEDS TO DUPLICATE ITS DNA, (…)
SO THERE IS ONE COPY OF EACH NEW CELL
THE DNA FORMS X-SHAPED CHROMOSOMES AND EACH ‘ARM’ OF THE CHROMOSOME (…)
IS AN EXACT DUPLICATE OF THE OTHER
THE CHROMOSOMESTAT LINE UP AT THE CENTRE OF THE CELL AND CELL FIBRES (…)
PULL THEM APART
MEMEBRANE FROM AROUND EACH OF THE SETS OF CHROMOSOMES, THOSE BECOME THE (…) OF THE TWO NEW CELLS
NUCLEI
THE CHYTOPLASM (…)
DIVIDES
MITOSIS ALSO MAKES NEW CELLS FOR (…) AND (…)
GROWTH AND REPAIR
MITOSIS FOR GROPWTH AND REPAIR ARE USED FOR…
ALL PLANTS AND ANIMALS TO GROW AND REPAIR DAMAGED TISSUES
