3. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar.
5. release of water vapor into the atmosphere from stomata in the leaves of plants.
10. living things that interact with other organisms in their environment and need other organisms in order to survive.
12. organic compound made up of amino acids.
14. plant that is growing where people do not want it.
15. structure produced by a seed plant that contains an embryo and food supply enclosed within a tough coat.
16. of, on, or relating to the earth
19. species that benefits and harms a host in a parasitic relationship.

1. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis

8. (two words)a biochemical process in which cells break down glucose and oxygen to make carbon dioxide, water, and ATP for energy.
9. type of cell division in which the number of chromosomes is reduced by half and four haploid cells are produced.
11. tiny grains that bear the male gametes of seed plants and transfer sperm to female reproductive structures.
13. having only one chromosome of each type; gametes are haploid.
17. a group of organisms that can mate with one another to produce fertile offspring.
18. physical environment in which a species lives and to which it has become adapted.
20. Reproductive structure; can be adapted for dispersal and survival in unfavorable conditions; found in bacteria, plants, algae, fungi, and some protozoa.
