EARTH AND LIFE SCIENCE - REPRODUCTION

1. REPRODUCTION

2. Describe the different ways of how representative animals reproduce OBJECTIVE

3. BIG QUESTION! How do different animals ensure continuity of species?

4. The production of offspring. It is a process that ensures continuity of life, survival of species, biotic balance, and facilitates evolution of species as well. Through it, organisms can pass on their traits to their offspring. These traits are passed on regardless of the type of reproduction involved. Reproduction

5. TWO FORMS OF REPRODUCTION asexual reproduction & sexual reproduction

6. ASEXUAL REPRODUCTION does not need two parents to produce an individual the offspring produced is the exact copy of the parent animal

7. FORMS: ASEXUAL REPRODUCTION two individuals will form as the parent divides in half BINARY FISSION

8. Bacillus subtilis two individuals will form as the parent divides in half

9. Clostridium perfringens two individuals will form as the parent divides in half

10. FORMS: ASEXUAL REPRODUCTION breaking of body parts into fragments followed by regeneration and regrowth of lost parts FRAGMENTATION

11. Starfish two individuals will form as the parent divides in half

12. FORMS: ASEXUAL REPRODUCTION an outgrowth called a bud grows and develops from the parent would eventually separate to become a new individual BUDDING

13. Plants

14. SEXUAL REPRODUCTION needs two parents to produce an offspring

15. union of a paternal sperm nucleus with a maternal egg nucleus to form the primary nucleus of an embryo. could happen internally or externally FERTILIZATION

16. External Fertilization occurs outside the female reproductive tract

17. Internal Fertilization fertilization that occurs inside the body of an individual.

18. 1. OVIPARITY THREE METHODS OF FERTILIZATION “egg-birth” eggs are fertilized internally it would complete its development outside the mother’s body. 

19. Oviparous Animals THREE METHODS OF FERTILIZATION

20. Oviparous Animals THREE METHODS OF FERTILIZATION

21. Oviparous Animals THREE METHODS OF FERTILIZATION

22. 2. OVOVIVIPARITY THREE METHODS OF FERTILIZATION “egg-live birth” eggs are fertilized internally and receive its nourishment through its yolk complete its development within the mother hatch inside of the mother and young are born live

23. Skinks are lizards belonging to the family Scincidae THREE METHODS OF FERTILIZATION

24. basking shark THREE METHODS OF FERTILIZATION

25. 3. Viviparity  THREE METHODS OF FERTILIZATION “live birth” eggs are developed internally receive nourishment directly from the mother’s blood through placenta

26. Viviparous Animals THREE METHODS OF FERTILIZATION

27. Viviparous Animals THREE METHODS OF FERTILIZATION

28. Viviparous Animals THREE METHODS OF FERTILIZATION

29. Viviparous Animals THREE METHODS OF FERTILIZATION YOU!

30. STUDY FOR A 15 ITEM QUIZ

31. This is a process that ensures the continuity of life and the survival of species. It is the production of offspring.

32. 2. This is a type of asexual reproduction where an outgrowth develops from the parent and eventually separates to become a new individual.

33. 3. This is a form of asexual reproduction where the parent divides in half to form two new individuals.

34. 4. This is the process of breaking off body parts, which are then followed by regeneration and regrowth of lost parts.

35. 5. This form of reproduction does not require two parents to produce an individual.

36. 6. This is the union of a paternal sperm nucleus and a maternal egg nucleus to form the primary nucleus of an embryo.

37. 7. This type of fertilization occurs outside the female's reproductive tract.

38. 8. This method of fertilization is also known as "egg-birth," where eggs are fertilized internally but complete their development outside the mother's body.

39. 9. This is a method of fertilization known as "egg-live birth" because the eggs are fertilized internally and develop within the mother, but they hatch inside before the young are born live.

40. 10. This method of fertilization is called "live birth" because the eggs are developed internally, and the embryo receives nourishment directly from the mother's blood through the placenta.

41. 11-13. Enumerate the 3 types of asexual reproduction 14-16. Enumerate the 3 types of sexual reproduction
