Plants and Animals: Cellular Differences

Plants and animals are both eukaryotes, meaning they have distinct nuclei. (Bacteria, by contrast, are prokaryotes, which means they don’t have a nicely organized nucleus.) Plants and animal cells have many other similarities: ribosomes, mitochondria, chromatin, cell membranes, smooth and rough endoplasmic reticula (ER), vacuoles, and Golgi complexes, among some other organelles we’re not studying…

Plants and animal cells have many other similarities: ribosomes, mitochondria, chromatin, cell membranes, smooth and rough endoplasmic reticula (ER), vacuoles, and Golgi complexes, among some other organelles we’re not studying in this unit. However, there are some fundamental differences between plants and animals on a cellular level:

  • cell wall in plants
  • chloroplasts (plastids) in plant cells
  • large central vacuole in plant cells
  • centrioles in animal cells
  • some differences in the structure and function of the Golgi complexes

Watch this video for a nice summary, and please do click on the links he posts at the end for a deeper explanation of the topics he covers.

The following video is a bit more ‘scientific’ and uses some nice computer animation to tour plant cells. It’s worth a quick watch, too.

On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you?
