Reproduction and Development Ii (Plants)

Question 1

Involves no union of cells or nuclei of cells and, therefore, no mingling of genetic traits, since the nucleus contains the genetic material (chromosomes) of the cell.

Answer 1

Asexual Reproduction

Question 2

Asexual Reproduction (Specialized Plant parts)

Answer 2

*Stolon
*Rhizome
*Tuber
*Corm
*Bulbs

Question 3

Particularly found in the sporophyte generation of bryophytes and earlier tracheophytes.

Answer 3

Sporogenesis

Question 4

Throughout the history of life, plant life have undergo adaptations and successful evolutions which could be observed in their reproduction and development.

Answer 4

Reproduction and Development

Question 5

Classification of Plants ( Bryophytes/Nonvascular Plants )

Answer 5

*Moss
*Hornwort
*Liverwort

Question 6

Classification of Plants ( Tracheophytes/Vascular Plants )

Answer 6

Seedless
*Lycophyte
*Monilophytes
Seed plants
*Gymnosperm
*Angiosperm

Question 7

also called metagenesis or heterogenesis, is the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.

Answer 7

Alteration of Generations

Question 8

The sexual phase, called the gametophyte generation, produces gametes, and the asexual phase, or sporophyte generation, produces spores asexually.

Answer 8

Alteration of Generations

Question 9

Five derived Traits of Seed Plants

Answer 9

*Reduced Gametophytes
*Heterospory
*Ovules
*Pollen
*Seeds

Question 10

Answer 10

Reduced Gametophytes

Question 11

gives rise to a male gametophyte (Heterospory)

Answer 11

Microspore

Question 12

gives rise to a female gametophyte (Heterospory)

Answer 12

Question 13

Ovule (gymnosperm)

Answer 13

Integument (2n)
Megaspore (n)
Megasporangium (2n)
