Perpetuation of Life

By karmi baon

What comes into your mind when you hear the word ‘inheritance’?

By karmi baon

but the genes that are inherited from parents matter more than the other.​

By karmi baon

how does a parent organism produces a new organism or offspring?

By karmi baon

​Reproduction is the process by which living organisms like human, animals,and plants form new individuals of the same kind.

• it is important for the perputuation of species

How does plant and animal reproduce?​

By karmi baon

​Two Types of Reproduction

​

• Asexual Reproduction

• Sexual REproduction​

​

By karmi baon

Multiple Choice

It is the creation of a new organism from a single or one parent and does not involve the combination of gametes or sex cells?

• Asexual Reproduction

• Sexual Reproduction

• Angiosperm

• Bulb

Multiple Choice

it is the type of reproduction that involves two parents and combination of gametes (sex cells) to produce a new organism

• Asexual Reproduction

• Sexual Reproduction

• Angiosperm

• Bulb

​Asexual Reproduction

​

Advantages

• the organism does not need to search for a partner​

• it requires less energy since no mating is needed

• it takes only a short perios of time

• produces many offspring at one reproductive cycle​

​Asexual Reproduction

​

Disadvantages

• no variation in the genetic makeup of the offspring

By karmi baon

Five plant parts used for asexual reproduction:

1. Stolons or runners

2. ​ Bulbs

3. ​Stem cuttings

4. ​Roots

5. Leaves​

Animal Asexual Reproduction

​

• Budding

• Gemmules

• Fragmentation

• Regeneration

• Parthenogenesis​

​

​

By karmi baon

​Sexual Reproduction

the offspring's traits ad genetic makeup is a combination of its parents.

​

Fertilization-> Zygote -> Embryo

​

Male + Female = Offsprings

​Sexual Reproduction

​

Advantages:

• It creates variation in the genetic makeup of the offspring

​Sexual Reproduction

​

Disadvantages:

• It requires looking for a partner

• it also requires more energy

• The rate of reproduction is slower.
