     Hey! Today we are going to be talking about plants. If you don't know what plants are basically all around you.

                                           :O
     So now you know what a plant is here is what we are going to learn today...

• Characteristics of plants :)
• Where did plants first come from? :)
• What is the difference between vascular and nonvascular plants? :)

 Time to get to the facts...

     Characteristics of Plants

     The first characteristic of a plant is that all plants are multi-celled. That means they have more than one cell. Most contain the green pigment chlorophyll. Chlorophyll is the thing that makes plants green. Some are not green.

      The next characteristic is all plants have eukaryotic cells. That is an organism whose cells contain complex structures within enclosed membranes. Most plants have roots or root like structures that hold them in the ground. People think all plants have roots, but they don't.

                                  :O

        Plants have adapted to nearly every environment on Earth. Most plants live on land, but many live in water.

Where Did Plants First Come From?

      Plants first came from the sea probably evolving from plant like protist. The evidence: both plants and green algae have the same type of chlorophyll and carotenoids in their cells. Carotenoids are red, yellow, or orange pigment.

What Is The Difference Between Vascular and Nonvascular Plants

     One difference is that vascular plants have a complex system that lets them give water throughout it's whole body. That lets the plant grow BIG. Nonvascular plants don't have a complex system and can't give water throughout it's whole body. That is why a nonvascular plant is small.

     Vascular plants produce flowers. Flowers are the start of the reproductive process. Nonvascular plants don't produce flowers so they produce reproductive seeds. They reproduce with spores. Vascular plants have true stems, leaves, and roots. Nonvascular plants have stems and leaf like structures. An example of a vascular plant is a tree. An example of a nonvascular plant is moss.
