Ferns
-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.

Pines
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
Why?
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
Largest species
Edible
Basic Information- Have chlorophyll
Lowest of food chain
can be unicellular or multicellular

I have learnt that pines are the largest family in the plantae family.

ReplyDeleteI have learn that algae are not plant and are actually Eukaryote. i also discover that they can reproduce sexually or asexually
ReplyDeleteI have learnt that ferns still retain a primitive lifestyle and that algae are not plants since each individual cell performs a specific function unlike plant cells where many cells can perform the same task.
ReplyDeleteI have learnt that some flowering plants do not have green leaves and are completely parasitic
ReplyDeleteI have discovered that seaweeds are a type of algae.
ReplyDeleteI learnt that stomata is evenly distributed over all surfaces and that they have 2 leaf vascular bundles per needle and have fascicles with 2 to 6 needles.
ReplyDeleteI have learnt that algae, although having chlorophyll, is not a plant, and is a protist.
ReplyDelete1. I have learnt about the different types of plants which plantae can be divided into, namely such as(but not all): Algae, Ferns, Pines and Flowering Plants.
ReplyDeleteI have learnt that the Plantae kingdom is further divided into four groups, mosses, ferns, cones and cones and flowering plants, with the moss as the earliest type of plant.
ReplyDeleteI have learnt that spores are found spore bags which are found on the underside of the fronds of ferns.
I've learnt that some ferns have a vascular system thats allows the fern to circulate water and other mineral slats from the roots and vice versa, that the pine genus is the largest in the plantae family.
ReplyDeleteI learnt that Algae are not plants but still can Photosynthesize
ReplyDeletei have learnt that plants can reproduce sexually and asexually
ReplyDeleteI've also discovered that plants can be classified into vascular and non-vascular plants.
ReplyDeleteNon-vascular plants have no true roots, stems or leaves. Thus, they are unable to transport water efficiently against gravity as water is transported from cell to cell via osmosis. Due to this, non-vascular plants are limited to small sizes.
Vascular plants have true roots, stems and leaves. Thus, they are able to transport water efficiently against gravity. Thus vascular plants' sizes are not limited, compared to non-vascular plants. Also, cuticle is present to prevent the loss of water through evaporation through the leaves.

I've learnt that plants are classified into (mosses), ferns, pines and flowering plants. Being non-flowering and reproducing by spores, ferns have retained a primitive life cycle.
ReplyDeleteI have learnt about the different groups of plantae (pines, flowering and ferns).
