I can explain the how the parts of a flower contribute to the reproduction of the flower. I can explain the difference between sexual and asexual reproduction. I can explain the relationship between genes, chromosomes, and DNA. I can predict possible genetic outcomes using a Punnett Square.

Flower Parts SPI 0707.4.2 Match flower parts with their reproductive functions. Pollination BrainPop Fruit Development

Number 1-11. Identify the parts of the flower.

Study Guide 4.2 KP Anther: produces pollen, attached to filament Stigma: top of female structure, receives pollen Ovary: contains ovules/ eggs Stamen: male structure (anther + filament), pistil: female structure (stigma, style, ovary) Study Guide 4.2 KP

Methods of Reproduction SPI 0707.4.1 Classify methods of reproduction as sexual or asexual. Asexual Reproduction Brain Pop

Sexual: 2 parents, offspring with traits from each, gametes= sex cells Asexual: 1 parent, genetically identical offspring Study Guide 4.1 KP

Heredity SPI 0707.4.3  Describe the relationship among genes, chromosomes, and inherited traits. SPI 0707.4.4  Interpret a Punnett square to predict possible genetic combinations passed from parents to offspring during sexual reproduction. Heredity BrainPop

Genes are located on chromosomes, which are in a cell’s nucleus You get 2 alleles (sets of instructions) for each trait 23 pairs of homologous (matching) chromosomes in a human Study Guide 4.3 KP

Genotype: represented by letters, describes genes received from each parent (like Bb) Phenotype: physical appearance you see (like brown hair) Two capital letters (BB)= homozygous dominant, One of each (Bb)= heterozygous, Two lowercase (bb)= homozygous recessive Punnett square predicts probability of offspring genotypes      Study Guide 4.4 KP

In flowers, sexual reproduction can occur when pollen is transferred from a A pistil to a stamen. B stamen to a cotyledon. C pistil to a cotyledon. D stamen to a pistil.

The male reproductive structure of a flowering plant is the A pistil The male reproductive structure of a flowering plant is the A pistil. B ovary. C stamen. D seed.

In flowers, egg cells are produced in the A pistil. B ovary. C stamen In flowers, egg cells are produced in the A pistil. B ovary. C stamen. D seed.

What is the main function of the flower part indicated by the arrow What is the main function of the flower part indicated by the arrow? A attracting pollinators B producing pollen C protecting the ovule D supporting the pistil

Which scenario describes an organism undergoing sexual reproduction Which scenario describes an organism undergoing sexual reproduction? A A single-celled organism divides during mitosis. B A yeast cell reproduces by budding. C New strawberry plants form from runners. D Two earthworms exchange sperm and egg cells.

A new spider plant can grow from part of the parent plant A new spider plant can grow from part of the parent plant. Which process does the diagram illustrate?   A pollination B sexual reproduction C asexual reproduction D germination

Which example could only be classified as an outcome of sexual reproduction? A when all of the offspring are genetically identical B when two of the offspring are produced from one parent C when one parent combines its genetic information with another parent to produce offspring D when the cells in the offspring have the same number of chromosomes as cells in the parent

In one type of plant, red flowers (R) are dominant to white flowers (r). Two plants that are heterozygous for red flowers are crossed. What is the probability that this cross will produce an offspring with white flowers? a.1/4 b.2/4 c.3/4 d.4/4

The table below shows four traits that occur in guinea pigs. Two parent guinea pigs that both express recessive traits are crossed. Which trait will most likely be expressed in the offspring? a.rough coat texture b.short fur c.black coat color d.white spots
