ASEXUAL REPRODUCTION – the production of new individuals from one parent by mitosis. New organisms are identical to the parent. BINARY FISSION – a type.

Reproduction and Cell Division

Asexual Reproduction vs. Sexual Reproduction

LO: SWBAT explain the difference between asexual and sexual reproduction and describe different types of asexual reproduction DN: Explain the differences.

Methods of Asexual Reproduction This is what it would look like if humans reproduced by fragmentation!

Asexual vs. Sexual Reproduction

Asexual Reproduction Section 2.6, p. 57. Sexual vs. Asexual There are 2 types of reproduction: ◦Sexual reproduction  Two parents contribute genetic information.

Asexual Reproduction. What is Reproduction?  Reproduction is the process in which organisms produce more of their own kind.  Asexual reproduction occurs.

KEY CONCEPT Many organisms reproduce by cell division.

Asexual Reproduction Asexual – the production of a new organism with out the fusion of sex cells. ONE parent is involved.

Types ASEXUAL REPRODUCTION. Types of asexual reproduction Fission Single celled organisms, such as paramecium and bacteria, which reproduce by splitting.

Plant Reproduction. the transfer of genetic material from parent to offspring 2 types = sexual or asexual Reproduction.

Topic: Reproduction Aim: How is the human body adapted for reproduction?

SEXUAL & ASEXUAL REPRODUCTION INVOLVE CELL DIVISION ASEXUAL REPRODUCTION INVOLVES ONE PARENT: through binary fission, budding, & regeneration –One organism.

ASEXUAL REPRODUCTION Involves only one parent Offspring are genetically identical to the parent.

Sexual and Asexual Reproduction

ASEXUAL and SEXUAL REPRODUCTION. Reproduction is the process of making offspring from one or two parents.

Reproduction a process whereby living things produce more living things All living organisms need to do it!!

5.2 Asexual Reproduction.  Asexual reproduction requires only ONE parent  Offspring have identical genetic information and therefore are identical to.

Creating Clones. In The House of the Scorpion and The X-Files episode ‘Eve’, the stories focus on human clones that are produced by reproductive cloning.

Asexual Reproduction. ASEXUAL vs. SEXUAL  Requires only one parent organism  Offspring genetically identical to parent (clones)  No specialized cells.

A comparison…. Any form of reproduction in which the offspring are genetically identical to the parent A single parent grows a clone or copy of itself.

Asexual and Sexual Reproduction

Asexual Reproduction Asexual Reproduction 1. One parent 2. No sex cells 3. Offspring produced by cell division 4. Offspring identical to parent (same DNA) 5. Several types

Types of Asexual Reproduction Binary Fission 1. Organism divides in half 2. 2 identical daughter cells produced 3. Daughter cells are half the parent’s size 4. Daughter cells grow, then divide too 5. In bacteria

Types of Asexual Reproduction Budding 1. Small bud grows out of parent cell 2. Two different sized cells made (with identical DNA) 3. Bud breaks off and grows 4. In yeast and hydra

3. Spores spores, which are single cells, are released from the parent and can develop into new individuals (bread mold) note: spores are different from seeds… they do not form from sex cells from 2 parents as seeds do.

5. Vegetative Propagation = Asexual Plant Reproduction when new plants develop from roots, stems, or leaves of the parent plant

Tuber each eye, if separated, will grow into a genetically identical potato plant

Runner above ground stems can be cut once little plants have roots… all genetically identical – asexual repro! strawberry plant
