1. Reproduction, Growth and Development in Living Organisms

2. Reproduction Defined Who can reproduce? Types of Reproduction
A species is defined as a group of similar organisms that can interbreed and produce fertile offspring
Types of Reproduction
Asexual: formation of offspring from a single parent
Sexual: two parents join together to form a new individual

3. Kingdom Protista Reproduction Growth and Development
Asexual Reproduction: one protist splits into two
Once Protists become too large to maintain a balanced environment, they will begin the reproduction process.

4. Kingdom Plantae Spores Seeds
Single reproductive cell that can grow into a new organism
Adaptation for life on land because it is light weight and easily carried by wind
Reproductive structure that contains a plant embryo
Provide a protective coat and nutrients until the embryo germinates
Two types of seed producing plants:
Angiosperms
Gymnosperms

5. Ferns: Seedless vascular Plants

6. Ferns: Spores on underside of leaves

7. Reproduction with Spores: Fern
Sperm
Spores being released
Spores on the underside of fern
Egg
Zygote (Fertilized Egg)
Mature Fern

8. Reproduction with Seeds
Gymnosperms (“naked seed”)
Reproduce using male and female cones
Male Cone: produces pollen
Female Cone: contains eggs

9. Life Cycle of A Gymnosperm

10. Gymnosperm Seeds

11. Reproduction with Seeds
Angiosperms
Reproduce using flowers with male and female parts. An ovary(fruit) grows around the zygote.
The flowers also act to attract pollinators, such as bees, butterflies, and other insects.

14. Kingdom Animalia External Fertilization Internal Fertilization
Sperm and egg meet outside of the body
Sperm and egg meet inside the female body.

15. External Fertilization
Frogs spawning

16. Growth and Development

17. Kingdom Plantae
Germination
A plant growing from a seed or a spore

18. Kingdom Animalia Metamorphosis
Transforming from an immature form to an adult form
Complete Metamorphosis
Incomplete Metamorphosis

19. Kingdom Animalia Amniotic Egg
Allowed the first reptiles to colonize land

20. Kingdom Animalia: Class Mammalia
Marsupial Mammals
Placental Mammals
Young develop for a short time in the mother and then complete their development in a pouch located on the outside of their mother
Give birth to live young that developed in the mother’s uterus
Placenta
An organ that passes nutrients and oxygen between mother and developing embryo
