Parts of PLANT REPRODUCTION

1. Sepal 2. Petals 3. Stamen 4. Anther 5. Filament 6. Pistil or Carpels 7. Stigma 8. Style 9. Ovary 10. Ovule

• The OUTERMOST WHORLS of a Flower • collectively called CALYX

Sepal

• Whorl inner to the Sepals • may be BRIGHTLY COLORED in some • Collective called COROLLA

Petals

• Whorl inner TO THE PETALS • The MALE reproductive structure of the flower • bears the male sporangis (Also known as "Microsporangia"

Stamen

• PART of the STAMEN that contains Microsporangia that DEVELOP INTO POLLEN GRAINS

Anther

• part of the Stamen that serves as THE STALK OF THE ANTHER

Filament

• INNERMOST WHORL of the flower • The FEMALE reproductive structure of the flower • bears the female sporangis (also known as "Megasporangia)

Pistil or Carpels

• part of the PISTIL where the POLLEN GRAIN derived from the Microsporangium attaches during pollination

Stigma

• Part of the PISTIL that serves as the STALK of the Stigma • LEADS to OVARY

Style

• found at the BASE of the PISTIL • contains ONE or MORE OVULES • Eventually BECOME FRUITS

Ovary

• CONTAINS the FEMALE Sporangia or Megasporangia • eventually BECOMES THE SEED

Ovule

Stamens and pistil occurs on SEPERATE FLOWERS but the SAME PLANTS

Monoecious ex: Cucurbita Maxima

Staminate and Pistillate occur on Seperate Plants

Dioecious ex: Carica Papaya

• Contain MICROSPOROCYTES • Contain TWO SPERM NUCLEI and ONE TUBE NUCLEUS

Male Gametophyte

• contain MEGASPOROCYTES

Female Gametophyte

• Transfer of pollen grain from the anther to the Stigma • may be Animal aided or wind-aided

Pollination

• Ovules become the seed • Ovary matures into the fruit

Embryo Development

One sperm and egg combine, forming a DIPLOID ZYGOTE, the future Embryo

Fertilization

Other sperm dudes with the 2nd POLAR NUCLEI, fornmming a TRIPLOID CELL that will develop into ENDOSPERM which is the tissue that serve as food reserve

Double Fertilization

2 types of SEED GERMINATION

1. Epigeal Germination 2. Hypogeal Germination

Occurs when the Cotyledon emerges above ground, thereby exposing the hypocotyl of the plumule

Epigeal Germination

Occurs when the cotyledon remains below ground, thereby concealing the hypocotyl

Hypogeal Germination

Types of flowers based on the presence of the whorls

1. complete 2. Incomplete

A flower with sepals, petals, stamens and carpels

Complete

flower that lacks one or more of the floral whorls

incomplete

Types of flowers based on the presence of reproductive whorls

1. Perfect / Bisexual 2. Imperfect / Unisexual
