Worksheets6.1 Asexual and Sexual Reproduction
Total questions: 21
Worksheet time: 11mins
What is asexual reproduction?
is a type of reproduction in which two cells, usually an egg and a sperm, join to form a zygote, which develops into a new organism with its own genetic identity
is a type of reproduction in which a new organism is produced from one parent and has the same DNA as the parent
What are the advantages of asexual reproduction?
Can increase populations rapidly
lack of diversity and the offspring looks the same as the parent.
Does not require a mate for reproduction to take place
It is complicated
What is a disadvantage of asexual reproduction?
Lack of diversity the offspring has the same genes as the parent.
Can increase populations rapidly
Does not require a mate for reproduction to take place
It's safer -organisms are not vulnerable whilst mating takes place.
What is Binary Fission?
develops an outgrowth which is detached from the parent and becomes a new individual.
the organism produce its own spores. These spores are genetically identical to the parent
during this type of reproduction the organism divides in half
Organisms can be produced from unfertilized eggs
What is budding?
the organism produce its own spores. These spores are genetically identical to the parent
only one parent provides DNA for the new organism, which would make the new organism or offspring genetically identical to its one parent.
A new organism is created from the roots, stems or leaves.
develops an outgrowth which is detached from the parent and becomes a new individual.
What is Cloning?
develops an outgrowth which is detached from the parent and becomes a new individual.
Organisms can be produced from unfertilized eggs.
during this type of reproduction the organism divides in half
only one parent provides DNA for the new organism, which would make the new organism or offspring genetically identical to its one parent.
What is Vegetative Propagation?
the organism produce its own spores. These spores are genetically identical to the parent
only one parent provides DNA for the new organism, which would make the new organism or offspring genetically identical to its one parent.
A new organism is created from the roots, stems or leaves.
develops an outgrowth which is detached from the parent and becomes a new individual.
All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -
makes its own food
is unicellular
live in a marine habitat
reproduces asexually
What are the gametes in animals called
Sperm and Pollen Cells
Egg and Pollen Cells
Sperm and Egg Cells
Blood and Sperm Cells
Which of following organisms can reproduce sexually AND asexually
Fish, Monkeys and Seahorses
Starfish, Aphids and Monkeys
Cactus, Mice and Sea Anemones
Aphids, Sea Anemones and Starfish
What is sexual reproduction?
A type of reproduction in which two cells, usually an egg and a sperm, join to form a zygote, which develops into a new organism with its own genetic identity
A type of reproduction in which a new organism is produced from one parent and has the same DNA as the parent
