2. Ethylene: Ethylene is a hydrocarbon that acts as a natural hormone in plants. It helps the process of ripening, and it can be found in apples.
14. Mitosis: Mitosis is the process in which a cell replicates. All organisms, like this carnation for example, use some kind of mitosis to grow and repair.
18. Prokaryote: A prokaryote is an organism that lacks membrane bound organelles and has a nucleoid region that contains the DNA instead of a nucleus. Cheese is an example of a prokaryote because it is bacteria.
7. Evidence of different alleles: An allele is an alternate form of a trait, and the two different petal colors of these pansies demonstrate this.
16. Phenotype: A phenotype is an observable trait. The hair in the picture has very dark blonde phenotype expressed.
10. Genetically modified organism (GMO): A GMO is an organism whose genetic material has been altered. Corn has been genetically modified to have desirable traits.
5. Gamete: A gamete is a sex cell. This begonia's gametes are found in its center.
1. Diploid: A diploid cell contains two sets of 2n chromosomes. This mandarin contains diploid cells with full sets of chromosomes.
3. Eukaryote: A eukaryote is an organism whose cells contain a nucleus and membrane bound organelles. All plants and animals have eukaryotic cells, so this weed is a eukaryote.
20. Tropism: Tropism is the growth or movement of an organism towards an environmental stimuli. These vines are exhibiting tropism because they are growing along the fence to gain the maximum amount of sunlight.
