Plant Science: Dissecting a Flower and More Plant Experiments

Find out how dissect flowers and learn about its structure with this simple hands-on dissection activity and other exciting experiments with plants for children. Dissecting a flower is a great way to visually show the different parts of a flower, which can be difficult to represent in a diagram in a book.

What you need to dissect a flower.

Any flower with large parts works well, for example:

Paper plates or cardboard sheets.

Magnifying glass – optional

Tweezers

Scissors

How to dissect a flower

Place a flower on a paper plate, tray, or sheet of cardboard. Try to identify the different parts.

Label the areas of the different parts of a flower on the piece of cardboard or paper plate and match the dissected pieces with the correct label.

Try to find the following flower parts:

Root – transports water and nutrients from the soil to the plant and keeps it anchored in the soil.

Petal – often brightly colored to attract insects.

Sheet – applications energy from sunlight for photosynthesiscreating oxygen and sugars for the plant to use as energy.

Pollen It is a fine powdery substance that contains male reproductive cells. It is produced by the anthers of seed plants.

Stem – the stem of a plant transports water and nutrients from the soil to the rest of the plant. The stem supports the leaves and flowers, allowing them to rise above the ground to be in the light.

Flower Dissection Challenge

Try to find a stigma, anther, an ovule and an ovary. A lily is a good flower to identify these parts.

What is pollination?

Pollination occurs when pollen from the anthers (male part) of a plant lands on the stigma (female part) of a plant of the same type. The stigma is sticky so that pollen can easily adhere to it.

Pollen can be carried by wind or insects. Once it has landed on the stigma of a plant, it travels down a tube where it fertilizes ovules, which then become seeds.

What is fertilization?

Fertilization occurs when male pollen cells connect with female egg cells.

What is germination?

Germination is when a seed begins to sprout and grow. One way to demonstrate this is to grow a bean in a jar discover the conditions necessary for a seed to germinate.

What are the best flowers to dissect?

Anything that has large pieces works well. Lilies are great, but watch out for pollen stains. Tulips, daffodils and lily flowers also work well.
