Kingdom Plantae
They are way cool
First the basics…
Multicellular
Eukaryotic (they have a nucleus!)
Autotrophs (make their own food)
But what is a plant?
A multi-cellular organism that uses water and sunlight to make its own food and is adapted to nearly every environment on Earth.
A little bit of info…
ALL plants need – sunlight, water, CO2
Plants contain: Chlorophyll
Which is used in : Photosynthesis (in the chloroplast)
Plants CAN’T move
Other Notes:
Nearly all plants have roots or root-like structures
Plants contain cell walls, which are made of cellulose
The Plant Kingdom is divided into DIVISIONS, not phylums
The 4 main divisions:
Mosses (Bryophytes)
Ferns (Pterophyta)
Conifers (Gymnosperms)
Flowering plants (Angiosperms)

Mosses
They are NON-VASCULAR
They reproduce using SPORES! Like who else?
They are typically found on tree trunks, rocks or on the ground – most live in moist areas
Moss is not good for eating though….
Let’s let our plant expert explain it! Let’s talk about Ferns… They reproduce by
SPORES! Ferns are different
from mosses because they have VASCULAR tissue! Series of long tubes They help carry water
and nutrients to other parts of the plant!
It’s an advantage because the plants can grow bigger and taller!
Ferns
They are the largest group of seedless vascular plants
Their leaves are called FRONDS
They have been on earth for about 360 MY
Most ferns grow in tropical areas or areas that receive a lot of rainfall
Let’s check in with our expert…

Let’s take a trip and recap! Conifers
The oldest trees alive are…
- Gymnosperms (that’s another name for conifers)
What is a gymnosperm?
- A vascular plant that produces seeds not protected by a fruit!
What are some characteristics of gymnosperms?
They have ‘naked seeds’ (ha ha)
They do not have flowers
Most leaves of gymnosperms are needlelike or scalelike
Green leaves always stay on branches
How ‘bout some examples?
Pines
Firs
Spruces
Redwoods
Junipers
Let’s look at a conifer! Flowering Plants
These plants are otherwise known as ANGIOSPERMS
An angiosperm is a vascular plant that flowers and has fruit with one or more seeds
They can be found pretty much everywhere –parks, fields, jungles, deserts, etc.
Some flowering plants develop into FRUIT yum

Flowering Plants
They are divided into 2 main groups
Monocots
Dicots
Examples of monocots: corn, rice, wheat and barley, bananas, pineapples, dates
Examples of dicots: peanuts, green beans, peas, apples, oranges and maple, oak, elm trees
