2 Angiosperms Monocot Dicot Page 623 Gymnosperms Seed Leaves Leaf Veins Stems Flowers Roots In the boxes below, include a computer diagram of a tree, leaves, a female cone, and a male cone of a gymnosperm, and describe the appearances of each using qualitative and quantitative descriptions. Tree Describe Close Up of Leaves Describe Female Cone Describe Male Cone Describe The term monocot and dicot refer to the number of (or ) in the seed.

3 Field Study: Local Flora 2 Photographs per plant: full plant AND a close-up, showing flower/cone. Include: you, your name, or ID Angiosperms Monocot 2 Monocot 1 Dicot 2 Angiosperms Dicot 1 Gymnosperms

4 Plant Tissue Directions: Use Figure 31.5(p.627) to label the diagram below. Answers: 1. Answers: pg Draw the following cell types and describe their structure & functions: Parenchyma Cells Collenchyma Cells Sclerenchyma Cells Relate & Apply: For each body structure named here, identify the best analogous plant tissue system. S Circulatory system: Skin: Adipose tissue (body fat) F

5 Flower Dissection Lab Purpose: Identify the parts of the flower & indicate which parts make up the male & female reproductive units 1. Common name of your flower: 2. Scientific name of your flower: Examine each of the following parts. Record how many you find in your own flower Example & Label Your Flower Structures Color male and female parts different colors. Sketch and label the parts of the flower. (An example is provided for you.) Directions: Count and record how many of each structure your flower has. a. Sepals (Thick outer parts that protect the flower when it is closed) b. Petals (Colored and often fragrant parts that attract pollinators) c. Anthers (Football-shaped male organ at the end of the stamen, analogous to testicles in mammals) d. Pollen Grains (Tiny yellow, precursor to sperm cells, made by the anther) e. Stamen (male reproductive organ, comprised of the anther and filament) f. Carpel (female reproductive organ: stigma, sticky nectar at the top, style leading to the ovaries with eggs at the base) g. Eggs (tiny granules of female gametes or sex cells, housed in the ovaries) Directions: Carefully separate and isolate each of the structures listed below. Mount each one below. Flower Structures Sepal Petal Anther Pistil Pollen

6 Hay fever is an allergic reaction to pollen floating in the air. Some plants that use the wind to spread their pollen are grass, trees and corn. Find or sketch a magnified image of pollen in the space provided Analyze and Conclude: 1. Observing: Were the anthers in your flower located above or below the stigma? How could this affect what happens to the pollen produced by the anthers? Explain your answer. 2. Applying Concepts: What structures did you identify on the anther? What is the function of these structures? 3. Applying Concepts: What structures did you identify in the ovary? What is the function of these structures? 4. Drawing Conclusions: When people eat fruit, what are they really eating? When people are allergic to pollen, what are they really allergic to?
