Review your understanding of organism growth and the environment in this free article aligned to NGSS standards.
Key points:
- An organism’s traits depend on both its genes and its environment.
- Genes make up the hereditary material inside an organism’s cells. Genes provide information about an organism’s traits.
- Genes can affect how an organism grows. For example, some dog breeds are large and others are small. Any influence of genes is called a genetic factor.
- An organism’s environment is all the things the organism is exposed to as it lives and grows. These things include temperature, light, food, and water.
- The environment also affects how an organism grows. For example, a plant will grow bigger if it is given fertilizer. Any influence of the environment is called an environmental factor.

Does a yellow dandilion turn into the white fluff version? Also if a dandilion grows some place that doesnt have a lot going on how do their seeds desperse? Do they just fall off? or do the seeds stay on until the plant dies?(10 votes)
It depends what you mean, by nothing going on,if you mean no wind or animal dispersal, it wound most likely fall to the ground.(6 votes)
i just realized that when the dandelion is older it grows white hair [i think](11 votes)
What if we interbred two species? Will the two different species provide their separate reproductive cells and fuse them into the offspring? Or is it something completely different?(5 votes)
If you interbred a species,the offspring would have half of both of the parents genes.Search up interbred species images, and it will show you what happens when you interbreed any species.(1 vote)
If genes are what made our faces etc, is it still in us now?(3 votes)
Why do dandelions or for that matter any plants have petals of different colours, is it's vibrancy that attracts potential pollinators to it?(2 votes)
Yes, many pollinators, like bees, are attracted to bright colors.(1 vote)
- How does a normal dandelion turn into the fluff one? Does it just poof into a fluffball?(2 votes)
Dandelions turn into the white fluffy ones because of the pollination in the air during spring(0 votes)

does a dandilion white stuff keep flying or does it land(1 vote)- The fluff on dandelions is attached to the seeds. The fluff allows the wind to blow the seeds to locations away from the parent plant.(1 vote)
