Pathak- Asexual Reproduction

Question 0

Budding

Answer 0

• a new organism develops as an outgrowth of the parent
• the new organism, called the BUD, is a tiny duplicate of the parent organism
• bud and parent may separate from each other or remain together and form a colony
• yeast

Question 1

Binary fission

Answer 1

• simplest type of asexual reproduction
• a one felled organism divided to form two daughter cells of equal size
• nucleoid/ DNA and cytoplasm divide equally
• DNA of offspring is identical to the parent’s
• bacteria, amebas, paramecia

Question 2

Sporulation

Answer 2

• spores can develop into a new organism through mitosis when environmental conditions are favorable
• formation of spores occur in bread mole, mushroom, mosses, and ferns
• haploid

Question 3

Parthenogenesis

Answer 3

Eggs develop oath out fertilization

Question 4

Regeneration

Answer 4

• the development of a new organism from a part of the parent organism
• ex. In a starfish, a single arm can develop into a new starfish

Question 5

Vegetative Propagation

Answer 5

• a part of a plant grows into a new plant
• the new plant is genetically identical to the parent plant
• use this method to grow seedless fruits and vegetables

Question 6

Tubers

Answer 6

• underground stems that contain stores food (starch)

- ex. White potatoes (the eyes are actually buds, which can develop into new plants)

Question 7

Runners

Answer 7

• stems that grow out over the surface of the soil from the existing stem
• at points along the runner, new plants grow
• ex. Strawberries, some grasses

Question 8

Rhizomes

Answer 8

• long, modified stems that grow horizontally under the soil
• new plants are produced at nodes along the stem
• ex. Lawn grasses, ferns, irises

Question 9

Bulbs

Answer 9

• Underground stems specialized for food storage
• food is stored in the thick leaves of the bulb
• each bulb can develop into a new plant
• ex. Onion

Question 10

Cuttings

Answer 10

• pieces of roots, stems, or leaves develop into new plants under proper conditions
• ex. Roses, Sugarcane, banana

Question 11

Grafting

Answer 11

• a cutting from one plant (SCION) attached to the main body of the rooted plant (THE STOCK)
• scion keeps its own identity
• ex. Seedless oranges and grapes
• portion of the plant that grows above a graft has the heredity of the scion
