Stem Morphology – Stems are some of the best things on earth.

Think of all the delicious stems you eat everyday!

Next to each untitled arrow, label the appro-

ready been done for you. You’re welcome.

Internal Stem Anatomy

Monocot Stem

This is an actual monocot stem

cross section as seen under a

microscope. Note that when

you look inside of stem from a

monocot (like a lily, corn, or

grass) the vascular bundles are

scattered throughout without

any particular pattern. The vas-

cular bundles house the xylem

(zips water up) and the phloem

(flows food down). The vascu-

lar bundles are the veins, that

carry food, water and nutrients

throughout the plant.

Dicot Stem

Here you see the vascular bun-

dles (xylem and phloem) are in

a circle around the edges of the

stem. Think about when you

cut into celery, you can see how

the little veins are in a semi-

circle… those are the vascular

bundles, dudes!

Label each of these stem

cross sections. Which is

a monocot, which is a

dicot?

Circle or highlight the

vascular bundles.

Internal Stem Anatomy

Here is a cross section of a woody tree (a dicot). Sure, you have seen the rings before, but now we are

going to explore what they are and what they do for the tree.

Internal Stem Anatomy Review

1. What is the xylem? What does it do?

2. What is the phloem? What does it do?

3. What is a vascular bundle?

4. List three monocot and three dicot plants.

Root Morphology – It’s what’s for dinner. True, you eat all kinds of roots and they

are super important for plants, the environment, and all the creatures of the world.

Here we have a pictures of a carrot and an onion.

We never eat onion roots, but we sure do love their

leaves. We do eat carrot roots though. How are

these two root types different?

Label the carrot and the onion. Next, label which is

a tap root and which is a fibrous root.

How are a tap root and fibrous root different?

Why are tap roots difficult to transplant?

What happens if I try to transplant a carrot?

Flower Morphology and Anatomy– Ain’t they pretty? They aren’t just

good lookers, they are responsible for all of the fruit we eat. Just think,

we would never have any honey either if it weren’t for flowers.

Flower Morphology and Anatomy

Fill in the Blanks:

The ________________ is the vase-shaped, female part of the flower located in the center of the flower.

The __________________ make up the showy part of the flower.

The small, green, and leaf-like structures that protect the developing flower bud before it opens are the

_______________________________.

The pistil consists of three parts: _______________________, ________________________,

_____________________.

Pollen is contained in the _______________________ of the stamen.

All sepals together are known as the __________________________. The collective term for all the pet-

als

is the _______________________________.

The ______________ is the enlarged portion at the base of the pistil, containing the egg cells.

When _____________________ occurs, the pollen unites with the stigma.

When _____________________ occurs, the pollen unites with the ovules.

The ___________________ ripens and becomes the fruit.

List five things that you found interesting about your flower dissection:

You will dissect an Alstroemeria flower. These are also known as Peruvian lilies. This is a very inexpen-

sive flower from Latin America. It can be grown in North Carolina as an herbaceous perennial. This

plant is a monocot (see that the flower petals come in multiples of three and the leaves have parallel

veination). Check out this flower now in person and begin your dissection exploration.

Flower Sex: The story behind the birds and the bees.

Pollination: This is the

____________ of pollen from the

_______________ to the _____________.

This is often carried out by:

A.

B.

C.

D.

Fertilization: This is when pollen

travels down the _______________ and unites

with the ________________. This will result in

the production of ________________ that will be

carried in the ____________________.
