Identify the type of reproduction described: Review: Identify the type of reproduction described: Two parents Offspring genetically identical to parents Uses mitosis One parent Offspring NOT genetically identical to parents Uses meiosis Used by more complex organisms h. Need sperm and egg cells to join SEXUAL ASEXUAL ASEXUAL ASEXUAL SEXUAL SEXUAL SEXUAL SEXUAL

2. Identify the cell division described: TWO daughter cells produced. Daughter cells NOT genetically identical to parent cell Used during ASEXUAL reproduction FOUR daughter cells Chromosome # stays the same Used for SEXUAL reproduction Replicates SOMATIC CELLS. Chromosome # splits in half Daughter cells genetically identical to parent cell Produces GAMETES. MITOSIS MEIOSIS MITOSIS MEIOSIS MITOSIS MEIOSIS MITOSIS MEIOSIS MITOSIS MEIOSIS

Topic: Reproduction Aim: Describe the different types of asexual reproduction. Do Now: Immunity Review ISA (5 minutes) HW: Respiratory and Excretory Systems take Home Test – Due Tuesday, March 29

A Identify structure A. ANTIGENS Refer to the diagram below which represents a pathogen. Answer questions 1 - 4 on the loose-leaf below. Identify structure A. ANTIGENS 2. Identify the substance produced that will bind to structure A. ANTIBODIES WILL ATTACH TO STRUCTURE A. A

3. Describe the body’s reaction when this pathogen enters the body in the space below. Be sure to use the following terms in your answer: pathogen, antigen, antibodies, shape. When a pathogen enters the body, antibodies will be produced. Antibodies attach to the antigens to help destroy the pathogen. The shape of the antibody and antigen must match perfectly. 4. Identify the type of immunity that would be the end result of this pathogen entering the body and how it can be acquired. A

4. Identify the type of immunity that would be the end result of this pathogen entering the body and how it can be acquired. Active immunity Acquire active immunity by: Getting the disease Getting a vaccine A

3. Binary Fission Equal division of cytoplasm Ex: Ameba, paramecia, bacteria

33 chromosomes MITOSIS 33 33

5. Budding Unequal division of cytoplasm The “bud” has the same # of chromosomes as parent Ex: yeast, hydra

1. Sporulation Formation of SPORES = cells produced by mitosis and grow into a new organism genetically identical to the parent Ex: fungi (bread mold, mushrooms)

2. Regeneration Ability to grow back a lost body part New organism can grow from part of parent (FRAGMENTATION) Ex: starfish, lobster, lizard,

Salamanders: Salamanders can regenerate legs Salamanders: Salamanders can regenerate legs. When a salamander is in the larval stage, it can regenerate a limb in thirty to forty days! Adult salamanders can also regenerate limbs, but it takes much longer and the leg is not as large as the original one.

Lizards: Lizards have the ability to replace lost limbs or a lost tail Lizards: Lizards have the ability to replace lost limbs or a lost tail. This is important because when a predator such as a hawk captures the tail, the lizard can escape. The new tail lacks the backbone of the original tail.

Crayfish: Cray fish can regrow claws, pinchers, or legs Crayfish: Cray fish can regrow claws, pinchers, or legs. It is easy to recognize the regenerated part because it is smaller than the other parts. Just like the lizard, it can break off a claw or leg so that it can escape when captured by a predator.

4. Vegetative Propagation Asexual reproduction in PLANTS Types: runners, bulbs, tubers, cuttings

Let’s review! Which type of cell division is used for asexual reproduction? Describe the offspring of asexual reproduction. 3. Explain the difference between binary fission and budding. 4. How are spores produced? 5. Which type of asexual reproduction is used by plants? Mitosis Genetically identical to parent Binary fission is an EQUAL division of cytoplasm. Budding is an UNEQUAL division of cytoplasm. Mitosis Vegetative propagation

The type of asexual reproduction in which involves the production of single cells by mitosis that are released into the environment is called regeneration binary fission sporulation vegetative propagation

The type of asexual reproduction in which one cell divides into to two cells that are of equal size is called regeneration binary fission sporulation vegetative propagation

Asexual reproduction in plants is known as regeneration vegetative propagation binary fission sporulation

Asexual reproduction that involves the regrowth of a lost body part is known as regeneration vegetative propagation binary fission sporulation

Asexual reproduction in which there is an unequal division of cytoplasm is called regeneration budding binary fission sporulation

Identify the type of asexual reproduction described. An organism grows back a lost body part. 2. Unequal division of cytoplasm. 3. Specialized cells are released and eventually develop into a new organisms that are identical to the parent. 4. Asexual reproduction in plants. 5. Equal division of cytoplasm. regeneration budding sporulation vegetative propagation binary fission

1. Identify the labeled structures in the diagram. 2. Identify the bones that protect the spinal cord. vertebrae 3. Identify the bones that protect the brain. cranium 4. Identify the bones that protect the heart and lungs. rib cage 5. Where is cartilage found? In rib cage, tip of nose, ears, between bones (joints), between vertebrae A cranium vertebrae rib cage B D C humerus E pelvis F femur
