Sex for Food or How to Attract a Pollinator Joyce Cadwallader Christine Tuaillon Brian White Mimulus spp. M. Cardinalis Red High nectar M. Lewisii Pink Low nectar Guiding Questions: Currently reproductively isolated How did this evolve? Can we model this using population genetics?

Pollination and Fertilization in Flowering Plants. Plant Propagation. Pollination. Begins when a grain of pollen lands on a receptive stigma. It ends when a pollen tube punctures the embryo sac. Pollen Grain = Generative nucleus + Tube nucleus.

Inheritance and Selection. Q1. What do we call getting characteristics from our parents?. A1. Inheritance . Q2. What do we call the process of choosing particular animals or plants to breed?. A2. Selection .

Seed Plants. Gymnosperms & Angiosperms. What is a seed?. A seed contains an embryonic sporophyte Has a protective coat and enough nutrients to support the sporophyte until it is ready to germinate Seeds differ depending on their mode of species dispersal… eg . wind, animals, water etc.

Angiosperms- Flowering plants. Key Features Produce seeds in fruit Flowers - promote pollination and fertilization Cross pollination or self pollination Fruit - protection and seed dispersal Endosperm - stored food for embryonic plant.

Gymonosperms mean naked seed. Seeds produced by gymnosperms like this Giant Sequoia. Most gymnosperms are trees, some are shrubs,most have needlelike or scalelike leaves. Gymnosperms are the oldest type of land plant. Cycads are about 175 million years old.

Allergies. Immediate hypersensitivity Excessive IgE production in response to allergens (antigens). Allergic Reaction. B cells secretes allergen specific Ig Helper T release cytokines which tell B cells to make IgE B cell switches from IgG to IgE IgE binds to mast cells and basophils

Chapter 2 Human Evolution. What is Darwin’s theory of evolution by natural selection and how well accepted is it? What characteristics do humans have in common with our nearest nonhuman relatives and where do these characteristics come from?

I Breathe What?. Chemicals. Exhaust. Pollen. Dirt. Dust Storms. Can Dirt in the Air be a Good Thing?. How does dirt get in your house?. Windows Doors Air Conditioning Pets You!. Facts About Breathing. You breath about 26,000 times a day (16-18 breaths per minute)

Social Insects. Psychology 3107. Introduction. Many Insects live in hives, nests or what have you Definite roles for different castes, usually only one female that lays eggs Other females are ‘sterile’. An Example. The life history of the Bumblebee

Mendel and His Peas. Genetics Part 1. Why don’t you look like a rhinoceros? The answer to this question seems simple: Neither of your parents is a rhinoceros. But there is more to this answer than meets the eye.

Angiosperm Reproduction. Review: Plants are characterized by an alternation of generations. haploid (n) - gametophyte... reproduce sperm and eggs via mitosis. Fertilization results in a diploid zygote (grows into a sporophyte) diploid (2n) - sporophyte...

Bee Keeping Course: Session III – Managing the Colony. Nectar & Pollen Plants of Illinois. NECTAR. Nectar is a sweet liquid (mostly sugar and water) made in special glands called nectaries that are found on flowering plants. Necatries are most often found by the base of a flower’s petals.

Genetics & The Work of Mendel. Gregor Mendel. Modern genetics began in the mid-1800s in an abbey garden, where a monk named Gregor Mendel documented inheritance in peas used experimental method used quantitative analysis collected data & counted them excellent example of scientific method.

LEAVES 23.4. Function. Photosynthesis Transpiration – pulling water up from the roots and out the leaves. Structure. Epidermis Upper – covered by cuticle Lower – contains stoma with guard cells. Cont. Palisade layer – many chloroplasts Mesophyll – many air spaces

The Not so Pink of Pink - Eye By : Katherine Davis , RN. So What is Pink - eye anyway ?. Pink-eye is clinically known as Conjunctivitis; which literally translates to, inflammation of the conjunctiva, (The name for the mucous membrane on the inside of the eyelid).
