Transcript of Plant Reproduction
For potatoes they reproduce asexually. The eyes on the potatoes have begun to sprout. If a potato is cut in to pieces each piece that contains an eye can be planted and will grow into a new potato plant. Grass plants spread by reproducing asexually. Instructions
Plant Reproduction Sexual Reproduction In Plants and Animals Requires the Production of Two Sex Cells! What are they? Tell Show They are an egg and a sperm. They get together to produce the zygote. The male part of a plant is the sperm and the female part is the ovaries. The female holds the eggs. The pollen is in the male. The ovule is in the female as well. The offspring produced by sexual reproduction are genetically identical or different? Why? Tell Show During asexual reproduction one offspring produces offspring identical to it. Why are they identical? Different because in sexual reproduction they have different traits from their parents and asexual reproduction they are genetically identical because the seeds just splits in half so they look identical. Tell Show Because the sex cells do not have to be present. They produce seeds instead of spores. Potatoes and Grass can reproduce asexually. Show and Tell Tell Show All flowers are produced by seed plants. Show and label a plants pollen (sperm) and ovule (egg). Distinguish Fertilization and Pollination Tell Show Fertilization- in sexual reproduction, the joining of a sperm and an egg
Pollination- transfer of pollen grains to the female part of a seed plant by agents such as gravity, water, wind, and animals Pistil Ovule Pollen Show and Label How are Flowers Pollinated Video Video Distinguish an Angiosperm from a Gymnosperm Tell Show Angiosperm- flowering vascular plants that produce fruits containing one or more seeds
Gymnosperm- vascular plants that do not flower, generally have needle like or scare like leaves, they produce seeds that are not protected by fruits Angiosperm Gymnosperm Insert a Female Cone and a Male Cone Typically found on a Gymnosperm. Label them!! Insert the female
reproductive organ of an angiosperm. Label the stamen (male part: pollen is produced here) and the ovary (female part: ovule or eggs are produced here). Show Male Cone Female Cone Show The End
