Sexual reproduction ● What is sexual reproduction? ● What is a diploid organism? ● When offspring get genes from 2 parents. Offspring is not exactly like parents. ● Organism with 2 copies of each chromosome

● What is a haploid cell? ● A cell with 1 copy of each kind of chromosome, not 2 copies. ● Gametes (egg & sperm) are haploid ● In plants, flowers or cones produce gametes.

● What is pollination? ● Function of ovules? ● When pollen is moved from stamen to stigma ● pollination photos pollination photos ● Pollen tube grows down style to deliver sperm to ovules in ovary ● Hold eggs

Fertilization-when male gametes meets egg

● What is fertilization? ● What is a seed? ● When egg and sperm join to produce embryo. ● Seed contains embryo, stored food, and protective coat. pics.jpg f

● What is a fruit? ● Ovary that matures and grows larger. Can be tiny (dandelion ovary) or large (watermelon), soft, or hard

Plant reproduction POLLINATION

14B Asexual Reproduction There are no gametes involved (egg and sperm) The genes of offspring are exactly like parents' genes

● What are some of the ways plants reproduce asexually? ● 1) Some, like strawberries, send out runners. g

● 2) Some plant's roots will form a new plant shoot. g

● 3) Leaf cutting-put leaf in water and it grows a new plant. water.jpg

● 4) Cut up a potato and the part with an “eye” will grow a potato plant

1) Name another animal pollinator besides insects. 2)What is the reproductive organ of most plants? 3)The ovule, when fertilized, becomes the seed or the fruit? 4)T or F. The ovary of a plant contains just one egg. 5) Name the female gamete cell. 6) Name the male gamete cell. 7) Name a non-living pollinator.
