Introduction to Human Anatomy Lecture 56 Notes: Flowers

Overview

Today we have a 39 minute lecture on fertilization and pollination.

Details

Some plants reproduce vegetatively or asexually.  Potatoes do it.  Each potatoe eye can become a new plant.  The top of a carrot is similar.  strawberries and cacti are included.

The outer structures are cevils, then petals, then the male parts called the stamen, then the female part the pistol.

In the very center of the flower is one pistol.  “Pistol packing mama.”  Ma Cass.  The very top is the stigma and it is sticky.  Pollen sticks to the pistol.  Right below the stigma is the style.  The bottom of the pistol is the ovary.  One or more eggs or ovules inside the ovary.

Surrounding the pistol is many stamens.  The number of stamens is monocot or dicot.  Monocots are multiples of 3, dicots are multiples of 4 or 5.  The anther is colored and contains the microgametes.  Monocot vessels are in a straight line.

If the plant is insect pollinated, the petals are colored.  The sepels are below the petals and may be the same or different color.  The corolla is all the petals.  All the sepels are the caylx of the flower.

***He goes through a very nice show and tell of a flower – the lily, the rose.***

A regular flower has similar petals.   An irregular flower has petals that are all different.  The corolla tube is when all the petals are joined together.

Either wind or insects are responsible for pollination.  The pollen grain can grow a tube from stamen to ovule.  Chromosomes move down the tube – this is fertilization.  The embryo becomes the seed.

microgamete+macrogamete = embryo=seed

Ovary enlarges to become the Fruit.

An apple is a fruit.  The bottom of the apple is the flower parts.  The stem is where it connects to the tree.  A fruit is an enlarged ovary and it has seeds in it.

Inside a peach or plum is a pit which is the seed.  Tomatoes, bell peppers and string beans are fruits.  Anything with seeds in it are fruits.  A vegetable is something that does not have seeds in it – its a meaningless word.

Rose hips are the fruit of the rose.  They provide vitamin C.

WHen there are both stamens and pistols inside, the flower is a perfect flower.  Some flowers have only stamens or pistols inside – an imperfect flower.  Staminate flowers have only stamens inside.

Keep the dogma simple. Make only 1 or 2 points.

Be forthright and powerfully direct. Speak only in the telling or ordering mode.

As much as possible, reduce concepts down into stereotypes which are black and white.

Speak to people’s emotions and stir them constantly.

Use lots of repetition; repeat your points over and over again.

Forget literary beauty, scientific reasoning, balance, or novelty.

Focus solely on convincing people and creating zealots.

Find slogans which can be used to drive the movement forward.

the trans isomer has the higher melting point; the cis isomer has the higher boiling point.

Why is the boiling point of the cis isomers higher?  There must be stronger intermolecular forces between the molecules of the cis isomers than between trans isomers.

Why is the melting point of the cis isomers lower?

You might have thought that the same argument would lead to a higher melting point for cis isomers as well, but there is another important factor operating. In order for the intermolecular forces to work well, the molecules must be able to pack together efficiently in the solid.

Trans isomers pack better than cis isomers. The “U” shape of the cis isomer doesn’t pack as well as the straighter shape of the trans isomer.  The poorer packing in the cis isomers means that the intermolecular forces aren’t as effective as they should be and so less energy is needed to melt the molecule – a lower melting point.

‘evergreen plant is a plant that has leaves in all seasons. This contrasts with deciduous plants, which completely lose their foliage during the winter or dry season

more branched isomers tend to have lower boiling points.

liquid boils when its vapor pressure is equal to the atmospheric pressure. Vapor pressure is determined by the kinetic energy of molecules.

Vapor pressure is caused by an equilibrium between molecules in the gaseous state and molecules in the liquid state.

Methane is a gas, up to pentane is a liquid
