Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The development of the microsporangia and the contained haploid gametophytes, (called pollen grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated. It is the part that contains the sperm
The insect carries the pollen grains to the stigma of another flower. 98) What usually occurs immediately after pollination in angiosperms?
3c. Image of Plant: Plant 4: Tomato 1a. Why did you select this plant? I selected this plant because is a 2b. Describe all of the ways what you could prepare this plant for consumption: 3c.
Name and describe the function of the five plant hormone groups discussed in your text. 5. Describe sexual and asexual reproduction in flowering plants. Be specific in regards to flowering plants. 1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons.
6.05 HONORS Lab Report: Dichotomous Key Directions: Use the Dichotomous Key on my site as you carry out this lab. Read all of the instructions below carefully, and fill out the BLUE portions of this sheet. Objectives: After doing this lab activity, you should be able to: Identify bryophytes, pteridophytes, gymnosperms, and angiosperms. Describe the characteristics and classification of the four main plant divisions.

Fred Schmitt Period 5 12/17/12 Mr. Simko Extracting DNA from a Strawberry Abstract This lab report is about how to remove DNA from a strawberry. The main purpose of this paper is to inform you on how to remove DNA from a strawberry. The hypothesis is, the DNA will look like twisted strands and fibers of string. We will use test tubes, coffee filters, and many other materials. Some important points in this experiment is that you need to crush to strawberry very well and when you add the lysis solution not to make bubbles while mixing.
I marked those with the Store Food Colors, the M&M colors and the unknown color. I then opened the FDC dye colors that came in the labpaq and placed three drops of each dye
Shape is also an important factor in the attraction of pollinators. Orchids mimic the dimensions and tactile features of the female pollinator, as well as the size of the labellum of an orchid being
Drosophila Inheritance Patterns Gage Howard May 7, 2012 Honors Genetics Mrs. Jennings ABSTRACT INTRODUCTION The purpose of this experiment was to determine the inherited patterns of the eye color and the types of wings of all of the fruit flies, Drosophila melanogaster. The wild type phenotype eye color is red, and the mutant eye color is sepia, a brownish- black color. The wild type phenotype wing shape is elongated, and the mutant wing shape is shorter and crinkled. The Drosophila melanogaster has four chromosomes. The gene that has a mutant inheritance it is found on chromosome two and three.
The color variation is limiting, the artist used green, red, and brown, yellow, black and white. However the painting does have great patter and rhythm, for we are able to see the repetition of the lilies and their stems, the shape of the stems follow the shape of the native girls waits
