Let’s check out the diversity of plants by looking at one currently proposed phylogeny, or evolution and relationships of a group of species. The first http://creativity-online.com/work/unacceptable-acceptance-letters-unacceptable-acceptance-letters/46547 split on the plant phylogenetic tree is between vascular and nonvascular plants.

Nonvascular plants lack extensive developed tissue systems that help move water and nutrients around the plant. These are commonly called bryophytes, and https://www.huffingtonpost.it/2016/04/20/college-violenze-sessuali_n_9735732.html include liverworts, mosses, and hornworts. Vascular plants make up all the rest. In fact, close to 93% of all known plant species are vascular.

These species can either be seedless or seeded, and that’s the next big split in the tree. Seedless vascular plants include lycophytes, which include https://www.prisonplanet.com/harvard-crimson-ad-warns-prospective-female-students-they-will-be-raped.html club mosses, and monilophytes, which include ferns. So our last, and largest, group of plant species are vascular and have seeds- but! Not all seeds are created equal.

The last big split in the plant phylogeny has to do with the type of seed- specifically, whether or not the seed has chambers during development. The two http://dailybruin.com/2016/04/27/keshav-tadimeti-sexual-assault-awareness-is-important-but-action-is-key/ groups of seed plants are gymnosperms and angiosperms. Gymnosperms have seeds that are not enclosed in chambers. In fact, the prefix “gymnos” means naked.

So yep - naked sperm it is. Angiosperms have seeds that develop inside of chambers, and these chambers typically come from flowers. So, angiosperms are also referred to as “flowering plants”, and they make up close to 90% of all plant species. Now that we’ve learned https://www.the-pool.com/news-views/latest-news/2016/16/powerful-videos-highlight-the-problem-of-rape-at-university a bit about how different plants are related to one another, it’s time to dive into one of my favorite things about any group of organisms- their adaptations to life on Earth.
