Revision Notes on Sexual Reproduction in Flowering Plants Flower

Revision Notes on Sexual Reproduction in Flowering Plants Flower Flower is a modified stem which functions as a reproductive organ and produces ova and/or pollen (1) Structure of the flower: The flower is commonly borne on short or long stalk called the pedicel. It has an upper swollen region known as receptacle (thalamus or torus).  (2) Parts of a flower: A typical angiospermic flower consists of four whorls of floral appendages attached on the receptacle: calyx, corolla, androecium and gynoecium. (i) Calyx: It is the outermost whorl of the flower. It is composed of leaf like green sepals. The sepals are essentially green in colour but in some cases they are coloured like petals. Such a condition of calyx is called petaloid. (ii) Corolla: This is the second whorl of the flower and consists of a number of petals. Petals are generally brightly coloured and sometimes fragrant which make the flower to become attractive. (iii) Androecium: It is the third whorl of flower and i...

Biology Questions

Following steps (sequences) occur in sexual reproduction in a typical angiosperm plant. A. Development that lead to the formation of male gametes (sperms): 1. Development of anther (microsporangium) 2. Formation of microspore (pollen grain) – micros porogenasis 3. Pollination 4. Development in microspore to form mature male gametophyte and formation of sperms/ male garnets. B. Development that lead to the formation of female gametes (Egg): 1. Development of ovule (mega sporangium) 2. Formation of megaspore (pollen grain) (mega sporogenesis) 3. Development in megaspore – formation of female gametophyte (embryosac) and female gamete. C. Fertilization D. Development of embryo and formation. A. Developments That Lead To the Formation of Male Gametes (Sperms): 1. Development of anther (microsporangium): (a) Development of micro-sporangia is eusporangiate type (i.e, from a group of initial cells) (b) Few cells in the hypodermal region become differentiated as archesporial cel...

Meaning of Embryo

Let us make an in-depth study of Embryo. After reading this article you will learn about: 1. Meaning of Embryo 2. Development of Embryo in Dicots 3. Development of Embryo in Monocots 4. Incompatibility  5. Special Modes of Reproduction. Meaning of Embryo: After fertilization, the fertilized egg is called zygote or oospore which develops into an embryo. The oospore before it actually enters into the process undergoes a period of rest which may vary from few hours to few months. Generally the zygote (oospore) divides immediately after the first division of the primary endosperm nucleus. Unlike gymnosperms where the early stages of the development show free nuclear divisions the first division of zygote is always followed by wall-formation resulting in a two-celled pro-embryo. Practically there are no fundamental differences in the early stages of the development of the embryos of monocots and dicots. But in late stages, there is a marked difference between the embryos of dico...
