GLE’s GLE 0707.4.1 Compare and contrast the fundamental features of sexual and asexual reproduction. GLE 0707.4.2 Demonstrate an understanding of sexual reproduction in flowering plants.

Types of Reproduction Asexual Sexual

Purpose of Reproduction To make sure a species can continue. Definition: Reproduction is the process by which an organism produces others of its same kind.

Asexual Reproduction A new organism (sometimes more than one) is produced from one organism. The offspring will have hereditary material uniform with the hereditary material of the parent organism. This means they will be genetically alike.

Types of Asexual Reproduction Budding Regeneration Fission (Binary fission)

Budding Process by which a new, duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created. Very common in plants;

Regeneration The ability to restore lost or damaged tissues, organs or limbs. It is a common feature in invertebrates, like worms and starfish.

Fission Also called binary fission. Becoming two by division of the complete organism. A type of cell division.

Sexual Reproduction Requires two sex cells (gametes) The gametes join to form an entirely new organism Different from the parent organism Genetically similar to parents

IMPORTANT! Asexual reproduction results in offspring that are genetically identical to the parent organism Sexual reproduction results in offspring that are genetically different from the parent organisms

What is the function of the flower? The flower helps the plant to reproduce. flower

The Parts of a Flower Most flowers have four parts: sepals, petals, stamens, pistil.

The parts of a flower Sepals protect the bud until it opens. Petals attract insects. Stamens make pollen. pistil grows into fruits which contain the seeds.

Flowers have male and female parts pistil stamen This is the name for the FEMALE part of the flower. pistil stamen This is the name for the MALE part of the flower.

The pistil (female part) stigma style ovary

The stamen (male part) anther filament pollen

The parts of a flower pollen stigma anther style filament ovary

Label your flower diagram Label the following parts on your diagram… the stamen the pistil stigma style ovary anther filament pollen

What have we learned today? We can label the parts of a plant and flower. We know that plants produce flowers which have male and female organs. We know that seeds are formed when pollen from the male organ fertilizes the female organ.

Later this week... We will find out more about how flowering plants reproduce. We will also find out that insects pollinate some flowers and discover how this is done!

Science Closure 2-18-14 The diagrams represent the way that three different organisms reproduce. Which of these classifies the reproductive method of all the organisms shown above? A segmentation B budding C asexual reproduction D sexual reproduction
