Characteristics of the Plant Kingdom1.Plants can make their own food;

they are autotrophs you know!2. Plants have many cells with

walls; we call them multicellular.3. Plants are green… Why, you ask?

Of what, you ask?Well, animals of course! You see…

plants can’t move… or can they?

Some say its because they have chlorophyll, others say its envy...

Section 8-1: Structure of Seed Plants

I. The Basic Structure:A. Seed plants are:__________________

_______________________________B. Tissue that forms a system of tiny tubes that transport water, food, and other materials is called __________

_____________.

vascular (have veins)

plants that produce seeds.

Section 8-1: Structure of Seed Plants

C. There are two types of tissue, they are:1) Xylem:____________________________

__________________________________2) Phloem:___________________________

__________________________________3) The main difference between xylem and

phloem is that: _____________________ _________________________________ _________________________________

Carries water from the rootsupward only in the stem.Moves food up from roots &

down from leaves using the stem.

where phloem canmove material both ways.

xylem moves materialupward only,

Section 8-1: Structure of Seed Plants

D. There are THREE major parts to the seed plant:

1) leaves:_________________________

______________________________2) stems:_________________________

_______________________________3) roots:_________________________ ______________________________

Collect & change sunlight into food using photosynthesis.

Made of xylem & phloem which transport food and water.

Absorb food & nutrients and help anchor the plant in place.

Section 8-2: Structure of Seed Plants

A. The function of a root is to: _________________________________________________

_____________________________________B.There are two basic plans that can be followed

for a root system:  1) Fibrous root:_______________________

__________________________________2) Tap root:__________________________ __________________________________

Anchor the plant and absorb water, minerals, & soil nutrients. Can also store food.

Has several main roots that branch off into the soil.

Has one main root with many small hair-like roots on it.

Section 8-2: Structure of Seed Plants

A. The function of the stem is to: _____________________________________________

B. The size of stems vary greatly in size.1) A Tree Trunk is a large _____________2) The _____ and ________ are stems.

C. There are two types of stems:1) Herbaceous, which are: ____________

________________________________

II. Stems: Provide

transport for food and water.

stem trunk branches

Stems that are green and soft.

2) Woody, which are: __________________ _________________________________

Stems of wood that are hard and stiff.

Section 8-2: Structure of Seed Plants Trees can show their age if youlook at a log or tree cutting.Trees have what are called _______ ______, which grow layer by layer each year.Count the number of rings below, and determine the tree’s age.

Age of tree:____ years old.7

annual rings

Reviewing this Section:

$ Why do you suppose there is a difference between xylem and phloem?

$ What is the importance of a root to a plant and to you?

$ What does herbaceous and woody mean?

$ Explain the difference between heartwood and sapwood.
