1. Plants What are the characteristics of all plants? What are the two types of plant? How do plants reproduce?

2. Characteristics All plants are: 1.Autotrophs 2.Multicellular 3.Eukaryotes Why aren’t fungi, bacteria, and plant-like protists plants?

3. Classification of Plants Two main groups of plants: 1.Vascular plants 2.Nonvascular plants

4. Nonvascular moss liverwort

5. Nonvascular  No developed transport system  For water & nutrients  No roots  Grow low to the ground  Absorb water and nutrients and pass from cell to cell  Reproduce using spores or asexual reproduction

6. Vascular Plants Seedless Ferns Gymnosperms Conifers Angiosperms Flowering Plants

7. Vascular Plants  3 types:  Seedless – reproduce using spores  Gymnosperms – reproduce using seeds  Angiosperms – reproduce using seeds surrounded by flowers or fruit  Have a transport system for water and nutrients

8. Plant Life Cycle

9.  Plants alternate between two stages: 1.Sporophyte (asexual reproduction) Stage: Spores produced and releasedSpores produced and released Spores create new gametophytesSpores create new gametophytes 2.Gametophyte (sexual reproduction) Stage: Plants release sex cellsPlants release sex cells Sex cells create zygotes (seeds)Sex cells create zygotes (seeds) Zygotes grow into sporophytesZygotes grow into sporophytes

10. Plant Reproduction  Plants can reproduce asexually:  Spores  Clones (a piece of a plant can grow into a new plant)  Plants can reproduce sexually:  Seeds (from another plant)  Seeds (from self)  Without seeds
