An Introduction to Plants
Plants come in an amazing variety.
These plants have no system for
moving water and nutrients
throughout the plant. (no
These plants have tubes that move water
and nutrients to all parts of the plant. (they
have plumbing)
What do you already know?
 How do you think non-vascular plants
move water and nutrients around. (hint:
we studied this process with the elodea
plants) It starts with an “O”
Osmosis and Diffusion
 Which plants, vascular or non-vascular do
you think grow the tallest? Explain why?
Vascular plants can grow the tallest because
they have plumbing to move water and
nutrients to different parts.

What type of plants are these?
Nonvascular Plants
 These plants are always short like
mosses and liverworts because they
need to be bathed (sitting or covered) in
 The water goes directly into each cell.
Plants are further divided
into plants with seeds and
 Plants without seeds = All
nonvascular plants and ferns,
horsetails, and club mosses.
 Plants with seeds = Gymnosperms
(nonflowering) and Angiosperms

vocabulary from your Powerpoint
All Plants Have
While there are a huge number of different
species of plants all plants have some
things in common.
1. All plants make their own food in a
process called ________________.
2. All plant cells have _____ ___________
which provide protection and support.
3. All plants have a cuticle. A waxy layer
covering the plant surface keeping it from
drying out.
4. All plants have a similar life cycle.
 What two stages do all plants go through
in their life?
Sporophyte and Gametophyte
Gametophytes create the egg and sperm for
What process happens in the gametophytes
to create the eggs and sperm?
(hint we studied this process in January
starts with an M)
 Why do plants have roots?
 1 To get water
 2 To get nutrients
 3 To anchor it to the ground (keep it from
falling over)
Angiosperms (flowering plants)
Angiosperms are vascular plants. What
does that mean?
They have a plumbing system (a vascular
A system of specialized cells that move
water, nutrients and food to all parts of the
Individual cells make up tissues which make
up ________ which make up _______
_________ which make up the plant. Just
like us! Except we’re not plants.

 What does xylem transport?
Water and nutrients
 What does phloem transport?
Assignment: (finish for homework)
 On a blank piece of paper draw a model of
a tree or plant starting with roots on the
bottom, stem or trunk, and finally leaves.
 Draw tubes representing the vascular
system with different colors for xylem and
phloem. (don’t forget a key and/or labels)
 Use arrows to show which way they are
