Cultivation and Gardening [6th Period]

[jquayle.livejournal.com]

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

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.
