Pine and Cones

pine tree.jpg

What?

Pine Tree

Where?

Lake Harriet Rose Gardens

So What?

I knew that I would find Pine trees here that I would be able to get cones from.

What?

A scale from a female cone and a male cone

Where?

From the tree in the photo above

So What?

I was unable to get a good photo of the microsporangia, but you can see the megasporangia on the scale. My borrowed camera doesnt work so well in close up

Gymnosperm cones

PINE TREE

CONES
microspore.JPG

WHAT: A gymnosperm (pine tree) and dissected cones
WHERE: my front yard
SO: I chose this tree because it was in my front yard, and very accessible. On the right is a scale from the female cone, and I think you can see the shapes of the megasporangia (kind of shaped like a heart?). On the left is a male cone with some of the scales removed. It is too small of a cone to see the microsporangia on the scales.

Ornamental Crab Apple trees

crab apple tree.jpg

What?

I believe that this is an ornamental crab apple tree in a grove of other ornamental crab apple trees.

Where?

The Lake Harriet Rose Garden

So What?

I was intrigued by the fact that some of these trees still had branches full of berries and some of them had lost nearly all of their berries. I do not know why this would be, but they seemed like candidates for quantitative traits of inheritance.

Leaves and Frequency

My plants have different size leaves. See? They're great.

Rose Bush–Frequency of Flowers

rose.jpg

This is a look at the quantitative differences among rose bushes in the mall area of the St. Paul campus. Some bushes seem to have more flowers than others.

Ivory Halo Dogwood Quantitative Traits

Loring school sign October 2008 004.JPG
WHAT: Ivory Halo Dogwood shrubs
WHERE: Loring Elemenary Schoolyard Gardens, North Minneapolis
WHY: There are 5 dogwood shrubs planted behind the sign. The two on the left are not as vigorous (they are shorter, they aren't as filled-out with branches and they don't have as much foliage) as the three plants on the right. They were all planted at the same time and given the same lack of care. Although all three examples I give to explain vigor are quantitative, I think that the lack of leaves is the most noticeable (maybe not in this picture) and therefore the primary difference I see between the same species of tree.

Thyme and quantity

Thyme
Thyme.JPG

WHAT: A group of thyme plants
WHERE: my home in South Minneapolis
SO: This is a picture of my thyme patch, which is not a single plant, but many that I planted from seeds. This summer I trimmed them back after they flowered, and they started growing again. An important quantitative element to these plants is the number of leaves that are on it. Since thyme is an herb, a desirable thyme plant would have vigorous leaf growth. You may notice that the plants in the back are taller than those in the front, also a quantitative measure. This is due to the way the sun shines in the window....an environmental influence.

Berries

100_1721.jpg

What: Berry bushes, short and squat
Where: Outside the Student Center, St. Paul Campus
So: The quantitative trait I am displaying is the amount of berries per shrub. Some of the shrubs, like the shrub in the foreground of this picture, had plenty of berries, while some of the shrubs in the background did not exhibit as many berries.

C.A. Quantitative Trait

IMG_1764.JPG
What: This is a picture of the Goldfish plant stem cuttings from class.
Where: The picture was taken in my kitchen.
So: I chose to take a picture of this plant because there are about 8 different stem cuttings that show the quantitative trait of "number of flowers per plant." Most of the plants had 1-2 flowers each, but some did not have any at all so this conveys a quantitative trait of the Goldfish plant.

Fruits: tomato & 'green' bean

bean tomato.jpg
WHAT: A tomato & green bean
WHERE: Picked from my Minneapolis garden
SO: The tomato is a berry, a fleshy fruit and the green bean is a simple, dehiscent fruit

Botanical Fruits

Orange.jpg

What: A hesperidium from an orange tree
Where: From a local grocery store
So: It is interesting to think of this orange as a 'hesperidium' instead of just as a fruit! I didn't realize fruit could be classified into so many different categories.

Sunflower Seed.jpg

What: A dry, indehiscent sunflower fruit
Where: Found at a local convenience store
So: It is hard for me to wrap my mind around the fact that a nut is really a fruit. It is fun to consider all of the possible sizes of 'fruits', that they range from coconuts all the way down to sunflower seeds!

Oranges and Sunflower

orange copy.jpg

What?
A Hesperidium fruit - an orange

Where?
In my kitchen

So What?
This is a "seedless" orange. It's been bred to reduce the size of the seeds so that they don't get in the way when you're eating it. They are about the size of a grain of salt in this picture.

sunflower copy.jpg

What?
A dry indehiscent fruit, an achene, a sunflower seed.

Where?
In my Kitchen.

So What?
It was a gift from a friend. It was from her favorite sunflower to plant. She gave me quite a few.

Legume & Avocado–Jenny

This is an example of a Fleshy Fruit.

This is an example of a Dehiscent Dry Fruit.

Eggplant and beans

EGGPLANT
Eggplant 1.JPG
WHAT: A fleshy eggplant
WHERE: from my garden in South Minneapolis
SO: This is a berry from an eggplant. It is unclear to me where the mesocarp ends and the endocarp begins, but the endocarp must be the tissue closest to the seeds.

LIMA BEAN
Lima Bean new.JPG
WHAT: Lima bean
WHERE: from my garden in South Minneapolis.
SO: This is a dry, dehiscent fruit with the ovary wall split open at the seam.
