-Stem, leaf and roots-Has Rhizome(a special root-like system )-Non-flowering-Reproduce by spores-Spores are found spore bags which are found on the underside of the fronds.
-Some ferns reproduce by leaves and roots-Has a vascular system ( This system allows the fern to circulate water and other mineral slats from the roots and vice versa )
-Grows better in damp and shady area.-Good for researchas they have retained a primitivelife cycle.

Consisting of over 325000 species of gymnosperms, most of them contain chlorophyll in their leaves and are capable of photosynthesis. however, some flowering plants do not have green leaves and are completely parasitic, relying on the host plant for their needs. flowering plants are highly adaptable to their surroundings and therefore have colonized practically every conceivable habitat on earth, some species even being able to live in the water. these plants reproduce by producing flowers and fruits. The main similarity between all flowering plants is that they produce sexual reproductive organs called flowers. A flower is composed of 4 major parts: petals, sepals, stamens and one or more pistils . The number, shape, size, and arrangement of these floral parts varies considerably with different plant. the flowers use animals to spread their pollen around to other plants, fertilizing them, causing their ovules to develop into fruits.
What is Algae?
A cluster of single-celled organisms called Protists.
A kind of Eukaryotes
NOT a plant
Only has a cell membrane, and each cell performs a unique function unlike plant cells.
Algae are mainly affiliated to 6 supergroups
Namely: Primoplantae, Archaeplastida, Excavata, Rhizaria, Chromista and Alveolata
BASIC TYPES OF ALGAE
Green Algae- Can survive in both Saltwater and Freshwater
Produces a large percentage of the oxygen we breathe
May pollute and produce foul smells
Basic Information- Have chlorophyll
Lowest of food chain
can be unicellular or multicellular
