Transcript of Reproduction Prezi

Asexual Reproduction
Disadvantages:
Plants that are identical are not able to adapt to changing environment conditions.
No variety because the offspring is a clone of the original
the species does not adapt at all or adapts very slowly when circumstances change
Reproduction Prezi
Binary Fission
Binary fission is when a single cell duplicates creating a clone of itself. Each new cell has the same genetic material as it's parent.
Asexual Spores
Budding
Vegetative Growth
The period of growth between germination and flowering is known as the vegetative phase of a plant. During the vegetative phase, plants are busy carrying out photosynthesis and accumulating resources that will be needed for flowering and reproduction.
Asexual Reproduction
ADVANTAGES -
With asexual reproduction you don't need to find a mate
Because you don't need to find a mate it's quicker
Once an organism is established in a habitat, it is able to reproduce quickly to produce many new individuals in that habitat.

Some fungi (ex. mushrooms) can reproduce asexually by producing spores. When these spores are produced, only one parent supplies the genetic material.
By: Dallis & Luke
Some animals can reproduce asexually by budding. A cell near the base of the organism produces a new group of cells called a bud. Examples of organisms that do this are Hydras and sea sponges.
Sexual Reproduction
Advantages:
Produces a new organism that results from a combination of two parents
Allows the best adaptations to be widespread within a species, especially in changing circumstances
Two parents can watch over the offspring
Sexual Reproduction
Disadvantages:
Offspring are not necessarily as well adapted to their environment as the parents
The genetic results, and often of fertilization, are unpredictable
Plants
Flowering plants involve the production of male and female gametes (gametes are cells that fuse with other cells during fertilization). The transfer of the male gametes to the female ovules in a process called pollination. After pollination, the ovules in the plant grow into seeds inside a fruit. After the fruit ripens the seeds get dispersed and over time, germinates.
Animals
Female mammals have internal fertilization, which means the egg is grown and fertilized inside the body. As oppose to fish. The females lay the eggs outside of their body and then the male fish comes over them and fertilizes.
