- 1WHAT IS MITOSIS?cell devision that happens in
body cells
resulting in
two genetically identical cells - 2WHERE DOES MITOSIS OCCUR?all over the body
- 3How many cell divisions in MITOSIS?1
- 4WHAT DOES MITOSIS CREATE?all cells apart from
GAMETES (sex cells) - 5MITOSIS - HOW MANY CHROMOSOMES? WHICH TYPE?46
(diploid) - 6Explain diploida cell that has a nucleus with
two sets of chromosomes;
body cells - 7How many cells does mitosis produce?2
- 8What is the function of mitosis?cellular reproduction,
growth - 9WHAT IS MEIOSIS?cell division that occurs to form
sex cells
resulting in
four genetically identical cells - 10WHERE DOES MEIOSIS OCCUR?sex organs
- 11How many cell divisions in MEIOSIS?2
- 12WHAT DOES MEIOSIS CREATE?gametes
(sex cells - male and female) - 13MEIOSIS - HOW MANY CHROMOSOMES? WHICH TYPE?23
(haploid) - 14Explain haploida cell that has
a nucleus with only
one set of chromosomes;
a sex cell - 15How many cells does meiosis produce?4
- 16What is the function of meiosis?sexual reproduction
- 17VOCAB BUILDING: DNA replicationDNA makes an
exact copy
of itself
Note - this happens before cell division - 18VOCAB BUILDING: chromatidone-half of
two identical copies
of a
replicated chromosome - 19VOCAB BUILDING: homologous chromosomeschromosome pairs
of approx.
the same length
with
genes for same characteristics
Note - 23 pairs in body cells - 20VOCAB BUILDING: parent cella cell that
divides
to produce
two or more
daughter cells - 21VOCAB BUILDING: daughter cellcells formed
when a
cell undergoes
cell division - 22VOCAB BUILDING: nuclear membranemembrane
that surrounds
genetic material
(also called nuclear envelope) - 23VOCAB BUILDING: asexual reproductionreproduction without gametes,
using mitosis - 24VOCAB BUILDING: multicellularorganism
consisting of
more than one
cell - 25VOCAB BUILDING: organ systemgroup of related
organs - 26VOCAB BUILDING: nervous systemcoordinates the actions of animal
and
transmits signals
between cells
(consists of spine, brain and nerves) - 27VOCAB BUILDING: endocrine systemorgan system of glands,
each secreting
different types of
hormones
directly into
the bloodstream - 28VOCAB BUILDING: circulatory systemorgan system
that
transports substances
around the body
(consists of heart, blood vessels and blood) - 29VOCAB BUILDING: digestive systemorgan system
that processes
food
consists of gullet, stomach,
small and large intestine - 30VOCAB BUILDING: respiratory systemorgan system
that brings in
oxygen
and gets rid of
carbon dioxide
consists of lungs and windpipe etc. - 31VOCAB BUILDING: gametessex cells
male gametes are sperm
female gametes are eggs - 32VOCAB BUILDING: haploiddescribes
a cell that has
a nucleus with only
one set of chromosomes;
a sex cell - 33VOCAB BUILDING: zygoteusually a
diploid cell
resulting from
the fusion of a
sperm and an egg
(two haploid cells) - 34VOCAB BUILDING: fertilisationjoining of
female and male gametes
to make a
new individual - 35VOCAB BUILDING: mitochondriaa small rod shaped structure
that
releases energy
during
aerobic respiration - 36VOCAB BUILDING: acrosomethe organelle
over the
head of sperm
that contains
digestive enzymes
