Types of Reproduction
➢ Asexual reproduction
• __________________ reproduction occurs when a new organism is produced from
•
•
__________________.
The __________________ material of the new organism is __________________ to the genetic material
of the parent.
So, the __________________ and the __________________ have all the __________________
__________________.
•
Organisms that are smaller and less complex are more likely to reproduce asexually.
•
__________________ __________________ like __________________ and __________________
reproduce asexually.
Many plants and fungi can reproduce asexually as well.
A few animals can reproduce asexually.

❖ Budding
• __________________ is the process when a new organism begins to form on the side of the parent and
eventually breaks off.
• Budding is most common in __________________ and __________________
❖ Regeneration
• __________________ is the ability to restore lost or damaged tissues, organs, or limbs. It is most
•
common in animals that do not have a __________________ (invertebrates) like worms and starfish.
Sometimes, if an organism loses a limb or if the organism is split into two parts, both parts will
__________________ the missing pieces, creating two organisms from one.
❖ Binary fission
• __________________ __________________ occurs when a
__________________ organism splits into __________________.
• Bacteria and protest reproduce by binary fission.
• First the parent cell makes a copy of its genetic material, then the cell
membrane pinches in and two new daughter cells split apart.
• Because the cell copied its genetic material, the two cell have the
______________ __________________.
➢ Types of Sexual Reproduction
❖ Sexual Reproduction
• __________________ reproduction requires __________________.
•
The female parent provides the __________________, and the male parent provides the
•
__________________.
The egg cell and the sperm cell combine to form a new individual.
The egg cell has genetic material from the female parent and the sperm cell has genetic material from the
male parent.
Therefore, the offspring will have genetic material from both parents, which is called
•
__________________ __________________.
Sexual reproduction allows new individuals to have genetic variation because they get a ______________
•
•
__________________ from __________________ __________________.
❖ Pollination
• __________________ is a form of __________________ reproduction.
•
•
•
•
•
Pollination occurs in __________________.
Pollen is taken from the male parts of one plant and delivered to the female parts of another plant, usually
by an insect.
The pollen then travels inside the flower and fertilizes an egg.
The egg will grow into a seed, which can become a new plant.
Pollination allows for genetic variation because the traits from __________________ are mixed.
