Flower Anatomy, Modes of Pollination, and beginning Meiosis
Pistil- the central part of the flower, pollen must land before seeds can form. Stigma- sticky top of pistil, catches pollen. Style- "stem" of pistil, tube pollen follows to ovary.
Ovary- base of pistil; where ovule located. Ovule- female portion of the plant's reproductive system. part within plant's flower pistil - becomes seed or site of fertilized egg development.
Male reproductive organ Filament – thin stalk - holds anther Anther – produce pollen, male sex cell
Cross pollination – Transfer of pollen from anther of plant A to stigma on plant B.
same Self pollination – pollen transferred from anther to stigma on same flower.
How Pollen Gets Around
Insects Brightly colored petals Strong sweet fragrance Nectar producing glands
Wind Large stigmas outside the flower Little /no fragrance Light, non-sticky pollen Lack showy petals
Birds Long tube shaped flowers Bright red and yellow flowers No odor
Mammals Strong fruity odor Flowers opening at night
Four haploid cells are produced from one diploid cell.
Produce haploid cells gamete Haploid – gamete or sex cell – 1 set of chromosomes Somatic Diploid – Somatic or body cell – 2 sets of chromosomes
Meiosis Ensures that offspring have the same number of chromosomes in diploid cells as the parent organisms.

Introduction to Plant Reproduction Introduction to AgriScience and Technology GHS Mr. Ham.
Reproduction in Angiospermophytes Topic 9.3. Assessment Statements Draw and label a diagram showing the structure of a dicotyledonous animal-pollinated.
We will learn that plants produce flowers which have male and female organs. We will learn that seeds are formed when pollen from the male organ fertilises.
Plant Reproduction. Two Forms of Plant Reproduction Sexual Reproduction Asexual Reproduction Meiosis + Fertilization Mitosis + Vegetative Propagation.
Objective What are the major parts of a plant including the anatomical parts and what are the distinguishing characteristics of each?
Asexual Reproduction Asexual reproduction involves only one parent who passes on the genetic information to their offspring. This sharing of genetic information.
Parts of the plant and their functions Importance of plants Without plants life on earth would not exist.
POLLINATION What we are going to learn about today….. 1)About the different parts of a flowering plant 2)What Pollination is. 3)How Flowers are Pollinated.
Roots: Anchors plant by keeping it firmly in place. Absorbs water and minerals. Stem: Holds up the plant. Transports water, minerals, and.
Sex Cells and Fertilisation Sexual Reproduction. Copy the following definition: Reproduction is the method by which the members of a species produce offspring.
