1. G A ________chromosome is one of several long, thin structures in a cell’s
_____________nucleus_ that contain the cell’s genetic material, DNA.
2. G Most of the life-cycle, of a “cell with a nucleus” is just_______ growing___ and making
_____copies______ of its organelles and its chromosomes. A typical life cycle of a cell is one
day long, but cell division (mitosis) takes of this only about 1 ¼ hours.
3. G Mitosis is the process of dividing the ______duplicated___ DNA of the cell into two new
____________nuclei___; and this is followed by cytokinesis in which the large cell with two
nuclei ____________splits______into two new cells.
4. G The first stage of mitosis is prophase, in which the nuclear membrane breaks__
___down_ and long strands of DNA organize themselves into condensed __chromosomes___.
5. G The second stage of mitosis is metaphase, in which _microtubles___ attach to the
chromosomes and the chromosomes get ______aligned_ in the middle.
6. G The third stage of mitosis is anaphase where the chromosomes __split___ as they are
____pulled__ to either side.
7. G The fourth stage is telophase where new nuclear membranes _reappear__ around the two
sets of chromosomes forming two nuclei within one cell. This is the __end_ of mitosis.

being a copy of the chromosome of one parent. In mitosis Every chromosome makes an
identical copy of itself and the identical two copies remain attached to each other at the centre,
forming an identical-pair. When chromosomes align in the middle during metaphase, there are
46 different “identical-pairs” aligned in the middle. When they separate, they form two
identical nuclei, so the two daughter cells are ___identical____.

parent cell and later breaks off to form a new organism.
4. G _______fission_ is the process in which a single-celled parent copies the genetic material
in its cytoplasm (so it will have _two__ identical copies) and then splits in two cells.
5. G regeneration is the process by which some organisms can _grow a new body part_ to
replace a lost or damaged part. e.g. a lizard grows a new tail to replace one that breaks off.
6. G Vegetative reproduction in plants is when the parts, like _roots, __stem_ and _leaves__
give rise to new plants. (e.g. a small branch of rose, a carrot or an African violet leaf can grow
into a whole new plant).

and [recycling] what cannot be used any more.

1.Mitosis is the process of dividing the duplicated DNA of the cell into two new nuclei; and
this is followed by cytokinesis in which the large cell with two nuclei splits into two new cells.
2. Once mitosis is complete a process called cytokinesis takes place where the [splitting] of the
cell occurs to form two new identical cells.
3.Cells without a nucleus, such as bacteria, divide (or reproduce) by fission.
4. Budding is the process by which a bud grows from the body of the parent cell and later
breaks off to form a new organism.
5. Fission is the process in which a single-celled parent copies the genetic material in its
cytoplasm (so it will have two identical copies) and then splits in two cells.
6. Regeneration is the process by which some organisms can grow a new body part to replace
a lost or damaged part. e.g. a lizard grows a new tail to replace one that breaks off.
7. G Vegetative reproduction in plants is when the parts, like roots, stem and leaves give rise to
new plants. (e.g. a small branch of rose, a carrot or an African violet leaf can grow into a whole
