Marine science 3.5 Plant and protoctist kingdoms

Plant and protoctist kingdoms

The syllabus states:

Seagrass:

1 state that seagrasses are marine organisms that belong to the plant kingdom and identify the main features of seagrasses

leaves that are organs of photosynthesis 

roots that secure seagrasses into sediment and obtain minerals 

rhizomes (underground stems) that connect individual seagrass plants, and for asexual reproduction flowers for sexual reproduction

Kelp:

state that kelp is an example of a macroalga (seaweed) that belongs to the protoctist kingdom and identify the main features of kelp

flat blades for photosynthesis 

gas bladders in some species to float the blades 

stipe that acts as a stem from which the blades develop 

holdfast to anchor the kelp to the substrate 

chloroplasts within cells for photosynthesis

Algae: Dinoflagellates

state that dinoflagellates belong to the protoctist kingdom and identify the main features of dinoflagellates

microscopic, single-celled organisms 

presence of chloroplasts for photosynthesis

 presence of two flagella for movement

Algae: Diatoms.

state that diatoms belong to the protoctist kingdom and identify the main features of diatoms

microscopic, single-celled organisms 

presence of chloroplasts for photosynthesis 

presence of a silica skeleton

My notes are here:

The syllabus toutches on seagrass as a example of marine plants, kelp as a macro algae and 2 types og micro algaes.

This is just scratching the surface of all the primary producers in the ocean
