1 02 Morphology (external) and Anatomy (internal) Packet: P5 Plant Leaves you will explore both compound and simple leaves. Enjoy the journey. Simple Leaf Morphology List five edible plant leaves: 5. Compound Leaf Morphology 1

3 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 appropriate anatomical structure. Some have already been done for you. You re welcome. List five stems you eat: 5. 3

4 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 vascular bundles house the xylem (zips water up) and the phloem (flows food down). The vascular bundles are the veins, that carry food, water and nutrients throughout the plant. Dicot Stem Here you see the vascular bundles (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 semicircle 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. 4

5 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. What is the xylem? What does it do? Internal Stem Anatomy Review What is the phloem? What does it do? What is a vascular bundle? List three monocot and three dicot plants. 5

6 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? List four functions of a root: List five edible roots: 5. Label and describe the root hairs and the root cap.

7 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. How to remember stamen- How to remember pistil- Four main parts of the flower: Complete Flower- Example: Incomplete Flower- Example: Perfect Flower- Example: Imperfect Flower- Example: Monoecious plants- What is it? Ex: Diecious plants- What is it? Ex: 7

8 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 petals 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. You will dissect an Alstroemeria flower. These are also known as Peruvian lilies. This is a very inexpensive 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. List five things that you found interesting about your flower dissection: 5. 8

9 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. Pollination Types Self Pollination: Cross Pollination: 9
