Lesson 3: Plant Reproduction

4. The arrangement of and relations between the parts or elements of something complex.
5. A period in an organism's life cycle when growth and development are temporarily stopped.
7. The production of new living organisms by combining genetic information from two individuals of different sexes.
10. The sweet and fleshy product of a tree or other plant that contains seed and can be eaten as food.
11. A flowering plant's unit of reproduction, capable of developing into another such plant.
14. A change or the process of change by which an organism or species becomes better suited to its environment.
16. The female organs of a flower, comprising the stigma, style, and ovary.
18. Each of the segments of the corolla of a flower, which are modified leaves and are typically colored.
19. A part of an organism that is typically self-contained and has a specific vital function.
23. The gamete-producing and usually haploid phase, producing the zygote from which the sporophyte arises.
25. The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization.
26. An unborn or unhatched offspring in the process of development.
27. A fine powdery substance consisting of microscopic grains discharged from the male part of a flower.

1. The protective outer coat of a seed.
2. The asexual and usually diploid phase, producing spores from which the gametophyte arises.
3. An activity or purpose natural to or intended for a person or thing.
6. Each of the parts of the calyx of a flower, enclosing the petals and typically green and leaflike.
8. A type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
9. The part of a seed which acts as a food store for the developing plant embryo.
12. The part of the stem of an embryo plant beneath the stalks of the seed leaves and directly above the root.
13. Containing two complete sets of chromosomes, one from each parent.
15. A small, typically one-celled, reproductive unit capable of giving rise to a new individual without sexual fusion.
17. The seed-bearing part of a plant, consisting of reproductive organs that are typically surrounded by petals.
20. The process by which a plant grows from a seed.
21. The part of a plant embryo that develops into the primary root.
22. Relating to genes or heredity.
24. The male fertilizing organ of a flower, typically consisting of a pollen-containing anther and a filament.
