Pre-quiz
Do your best to answer the following questions.
1. What are the things that all plants need in order to survive?
Answer:
2. Name one type of vascular plant.
Answer:
3. Name one type of nonvascular plant.
Answer:
What do plants need?
Sun
Air
Water
Nutrients
1. What are things in the diagram that plants need?
Answer:
2. How does the plant get what it needs from the soil?
Answer:
Diffusion
Diffusion is the movement of particles from a high concentration to a low concentration.
Particles will diffuse until there is a balance.
Particles
Cell Membrane
Movement of particles
High concentration
1. In what direction are the particles diffusing?
Low Concentration
Nonvascular Plants Use Diffusion
Because nonvascular plants don’t have vascular tissue they need to use diffusion to move
water, nutrients and sugars to the cells that need them. Diffusion is much less efficient and
can not move them as far as vascular tissue. Because of this they can not move nutrients
water and sugars they can’t grow very tall. Nonvascular plants only grow up to 8 inches
long!
Plant Cells
1. What do nonvascular plants use to move the things that their cells need?
Answer:
Vascular plants use vascular tissue to deliver the cell’s needs.
Vascular tissue consists of little tubes that transport nutrients and water from the roots up
to the leaves and pathways that move sugars from the leaves to the rest of the plant. This
allows them to move the stuff the cells need much farther. This is what allows trees to
grow so tall. Growing taller allows vascular plants to better compete for sunlight.
Sugar and CO2
Water and Nutrients
1. What would happen to the leaves if a vascular plant lacked vascular tissue.

1. In the video, what do you notice is the most obvious difference between vascular and
nonvascular plants?
Answer:
2. What advantage do you think this gives vascular plants?
Answer:
Directions: Read the following text and then answer the questions below.
Nonvascular plants are those plants without a vascular system (xylem and phloem).
Although non-vascular plants lack these particular tissues, a number of non-vascular
plants possess tissues specialized for internal transport of water.
Vascular plants have vascular tissues, which circulate resources through the plant. This
feature allows vascular plants to evolve to a larger size than non-vascular plants, which
lack these specialized conducting tissues and are therefore restricted to relatively small
sizes.
1. Describe what the main difference between nonvascular and vascular plants is.
