Employers that set up money purchase plans must declare a set contribution level each year in the plan document, based on employeesâ salaries. Companies can contribute up to 25% of the total annual compensation of all plan participants, up to 100% of each participantâs salary or $54,000 (in 2017, up from $53,000 in 2016), whichever is less.
There are important distinctions between seagrasses and seaweed. Seagrass can easily be confused with marine macroalgae, or seaweed, but there are many important differences between the two. While seagrasses are considered vascular plants and have roots, stems and leaves, seaweed are multi-cellular algae and have little or no vascular tissues.
The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and the stoneworts. No definition of algae is generally accepted. One definition is that algae have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells. Some authors exclude all prokaryotes and thus do not consider cyanobacteria (blue-green algae) as algae.
