1. Unit 7 Chapter 24 Reproduction in Plants

2. Alternation of generations
The basic life cycle pattern for most plants
Sporophyte stage
Diploid, asexual,
produces spores
Gametophyte stage
Haploid, sexual,
produces gametes

3. Vegetation Propagation
A type of asexual reproduction where a new plant is produced from existing plant organs or parts
Ex: plant “cuttings”

9. Flower structure Petals Sepals Stamen (male organ)
Colorful, to attract pollinators
Sepals
Leaflike, to protect inner organs
Stamen (male organ)
Contains anther, produces pollen
Pistil (female organ)
Contains ovary, produces eggs

10. Life cycle of a flowering plant
Double fertilization
One sperm joins the egg, while the other joins the central cell, forming the endosperm
Endosperm
Food storage tissue that supports development of growing embryo

14. Seed germination
The beginning of the development of a new plant after a period of inactivity, called dormancy
First to appear is the radicle (embryonic root) followed by the hypocotyl (embryonic stem)

15. Seed (containing embryo plant)
to mature plant, capable of
photosynthesis
