Cultivation and Gardening [6th Period]

Each student has a microscope, dissection tools (as listed in handouts) and a selection of lilies, daffodils, or tulips to dissect as needed.

Have at.







Dissection
Equipment






The pictured dissection equipment from left to right is
(1.) a teasing or dissection needle which used to
pull apart muscle tissue, (2) dissecting scissors
which are used to cut through tissue, and (3) a scalpel,
which is a knife used to slice through and cut tissue.








Plant Dissection


Many
kinds of flowering plants, such as lilies, daffodils, or
tulips are commonly subjects for dissection in
biology.    The
flower is the
plant structure specialized for reproduction in advanced
plants.   The processes of meiosis and fertilization
occur in the flower.   







Some Key Flower structures





petals: colored parts inside the sepals which
attract insects



sepals:
structures which are usually green outside the
petals which help to protect the flower



stamen
:  forms the male reproductive organ and
consists of an anther and a filament




anther
: pollen box in which pollen grains are formed
containing the genetic material which produces sperm



filament
: supports the anther



pistil or carpel
: female reproductive organ which
consists of three parts




stigma
: found at the top of the pistil, is often
sticky and hairy adapting it to catch and hold pollen



style
: tube-like connection between the stigma and the
ovary


ovary: enlarged part of the pistil attached to
the receptacle (stem tip on which the flower rests) and
contains the ovules

ovules: small white structures within the walls
of the ovary which produces the plant egg cells

Ooh, cutting things up. Walter can get behind that curriculum.

He sits down with the handout from a prior class and begins to meticulously dissect the tulip in front of him.

It's easy enough, but would probably be more fun with a dissection partner.

The Scottish Thane is thrilled.

HE GETS TO CUT THINGS.

He promptly gets straight to work.

This will show them. This will show all of those trees from Birnam Wood. He will get his revenge, in the torment of their smaller, more vulnerable cousins, and THEY WILL LEARN.

The Mun has had a long, long day.

Normally, Sharon would bounce. But she's feeling oddly tired as her player should be in bed, and so simply walks to sit down. Dissecting seems an easy task.

Precise cuts, careful movements. Shortly, she is lost to the real world as she dissects her way into a new understanding of plants.

Pippi forgets herself and juliennes her first flower.

The second one goes better.
