Science project idea on where seeds are produced on the plant.
Where Seeds are Produced- Science Project Idea
It is a common observation that seeds are produced in some way by the flowers of a plant.It will be well for us, therefore, to examine a flower.An examination of a typical flower, such as a pear blossom or bean or pea blossom, will lead us to find flowering parts.
The outermost parts are green leaf-like structures called sepals.Together they make a cup-shaped formation around the base of the flower called the calyx.Just inside of these are the colored parts of the flower called the petals.The petals together constitute the corolla.Next there are a number of little stalks with knobs on their tops.These are the stamens, the stalks being called filaments, and the knobs at the top, anthers.The anthers are little box-like structures containing a powdery substance called pollen.The center of the flower is occupied by the pistil, of which there are usually three divisions: an enlarged part at the base called the ovary, one or more little stalks running up from this called styles, and at the top of the styles enlargements usually slightly rough and moist called stigmas.If the ovary is cut through, there will be found in it small seed- like structures which are called ovules.Very evidently, these are the parts of the flower which will develop into seeds.
Science Project Idea Pick some different flowers of different plants and draw them.Show the differences and similarities of the plant flowers and explain why such differences occur. {mosloadpostion advert2}
