UPDATE: Plants Under a Microscope & Rapid Cycling Brassicas

Ive almost completed my portfolio for diversity of life 1. I have to do drawings of samples of angiosperms:

1. root
2. shoot
3. stem
4. leaf
5. epidermis
6. inflorescence

After this I did 3 sections of gymnosperms to compare and contrast. All of my samples are from pine. I did an ovule, stem and a leaf. (below: left to right, stem, ovule and leaf)

I had to look at 3 live cultures of algae: Volvox, Spyrogyra and Chlamydomonas and make detailed drawings of them. 

The Chlamydomonas moved about a lot and so had to put a Protozoa solution on it to slow the algae down so they were easier to see. 

(Below left to right: Volvow, Spirogyra & Chlamydomonas)

The third section is about rapid cycling brassicas. Each week they'd grow more and more and we had to draw detailed drawing of them at each stage every week. In the picture below you can see the development from when it had just started growing all the way to it producing fruit (seed pods). 

I have done most of the drawings, now I just have to do the write up which is all about the process of growing the Rapid Cycling Brassicas and describing them etc. I will show my drawings once I've finished my portfolio.

I have more pictures on my Flickr of you want to look at the rest! Plants Down a Microscope & Rapid Cycling Brassicas

Botanical Gardens of Wales

Last week I went on a field trip to the Botanical Gardens of Wales. This was for  my Diversity of Life 1 module.  Early Tuesday morning we set off to go there. Our next assignment is on Fynbos plants which before this trip I knew little about. this is what the trips main focus was on.

The first thing we did was get our complementary tea and welsh cake and were given a presentation about DNA barcoding and how they were progressing.  after which we then went to the Great Glasshouse. this is a mediteranean house and is where we spent most of our day. We were given a talk and shown around  (mainly the South African part) and were shown all the ways that these plants are adapted to their habitats.
 Many of them have lots of thin hairs on their thick leaves to potect itself from the sun and heat.

The king protea has big leaves. these leaves get bigger and waxier as they get older. as well as having big and hard leaves to protect it from the heat, it also moves throughout the day so that the leave edges are always facing the sun rather that the larger surface of the leaf. (Picture of King Protea; Protea cynaroides, on the right).

After we were finished with the talk  we had a tour around the rest of the gardens. There was an installation called the 'ghost forest' which are parts of big tropical trees. The gardens are their final resting place, after travelling to various places.  they will eventually rot and decompose here and will be interested to see what will grow there afterwards.  They have a small Japanese garden, bee hives and vegetable patches to name a few of the things we saw, as well as lots of outdoor flower beds organised in families.  the final thing we saw on out tour was the tropical house. I like this because of how diverse the plants are in it and how much brighter the plants are.

this bought us to lunch time so we had a break and then were free to look around anything we may have not been to or may want to go back to. I went to the 'amazing fungi' area and then back around the rest of the great glasshouse as it was big and it gave us a chance to look around and get some more information about the fynbos plants.

Soil profile

In principles of ecology we had to make a soil profile on a common near Caerphilly. The idea of this is to dig down however far you need to go. We did a metre. We dug a hole big enough to be able to see the soil profile. This is where you can see the different layers of the soil. 

You can clearly see the layer on this the photo (above).

This was a particularly hard practical as it was a very stoney area and there were lots of large rocks we had to dig out, and when only you and one/two others in your group wants to do any hard work, a few hours of doing this really has a toll on your hands and back. 

Whilst we were digging we had to test the soil types of each layer in various ways, such as how moist it was or how well you could mould it/roll it into a ball; as well as write about the area and the weather at the time we were there. 

The picture above shows the start of the hole, this was our third attempt as this patch had the least amounts of large rocks. There were still a lot but at least we could budge these ones without breaking the shovel/spade.

Plants under a Microscope

My portfolio for my practicals in Diversity of life 1 I have to draw prepared angiosperm sections. I have to draw and fully annotate the following: root, shoot, stem, leaf, inflorescence and epidermis. the rest of the portfolio will be doing the same for some gymnosperm tissue sections and then for some algae and lower plant live cultures. the second part will be writing about the plant life cycle using rapid cycling brassicas.

Meanwhile doing the drawings of the Angiosperm sections I took some pictures down the microscope. 

(Above; l.s Inflorescence, 4x/0.10)

 (Above; t.s leaf, 10x/0.22)

(Above; l.s root tip, 4x/0.10)

(Above; l.s tangenial stem, 4x/0.10)

(Above; l.s radial stem, 4x/0.10)

(another stem that I looked at but didn't use for my portfolio.)

...and now to get on with all this drawing...
