How Flowers Eat and Grow–Photosynthesis

Some facts about flowers are that flowers get their food from sunlight, water, and minerals in the soil; flowers are the reproductive parts of a plant, and plants make their own food by photosynthesis.

Plants can photosynthesize due to cells called chloroplasts that contain chlorophyll; this is what makes plants green. Sun strikes the chloroplasts and combines with carbon dioxide that plants get from their leaves, and water that plants get through their roots, to produce sugar, or glucose. This is the plant’s food, and this gives the plant energy to grow and produce flowers.

Plants take in carbon dioxide, or CO 2 ,through little holes in their leaves, which are called stomata. They then produce and release oxygen through the stomata. Plants and animals were meant to live together! Animals need the oxygen that plants put out, and plants need the carbon dioxide that animals put out.

Sometimes people add fertilizer, or plant food, to give plants extra minerals and nutrients so that they can grow better. Fertilizer does not take the place of sunlight and water.

Without sunlight and water, plants will die.

Parts of a Flower

The outside of a flower that can be seen easily consists of petals, the colored part of the flower, and the sepals, the small green structures that look like little petals at the base of the flower.

Inside a flower is the pistil, or the female parts of the flower. The pistil looks like a vase with a long neck. The top of this “vase” is called the stigma. The long neck is called the style. The bottom, fatter part of the vase is the ovary and contains the ovules, or eggs.

Also inside the flower are the male parts of the flower, called the stamens. The stamen consists of the anther and the filament. The filament looks like a stiff, standing piece of string. On top of the filament is a rounded ball of pollen called the anther. The pollen is usually a bright yellow or orange color.

Pollinators like bees, animals, and birds come and gather pollen from the flowers. The pollen sticks to their bodies. When they go to visit another flower to gather more pollen, the pollen from the previous flower drops into the pistil of the new flower, fertilizes the eggs inside the ovary, and seeds are made.

Interesting Facts about Flowers

Flowers did not always exist; they first appeared 140 million years ago. Before that, ferns and cone bearing trees dominated the earth.

Several centuries ago in Holland, tulips were more valuable than gold.

Broccoli is actually a flower.

Some plants such as orchids do not need soil to grow-they get all of their nutrients from the air.

Some plants produce toxic substances that kill other plants around them-the sunflower is an example.

Carnivorous plants are flowering plants that eat bugs and small animals! For example, the Venus fly trap has leaves covered by little hairs. When a bug lands on the hairs, the trap snaps shut and digestive juices digest the bug. Other carnivorous plants such as pitcher plants have leaves that form pitchers that are full of digestive fluids. Insects, frogs, and other small creatures are attracted to the nectar and bright colors on the pitchers and flowers. Some unfortunate critters fall in, drown, and are digested.
