ferns or huge redwood trees. There are scientists who study plants. They find new ones all the time. They divide plants into two main groups: flowering and nonflowering. Flowering plants make up about 90% of all plants.
There are many kinds of plants. The first plants were small and did not have flowers. Over time, the number of plants grew. Today, there are about 400,000 kinds of plants. They might be simple ferns or huge redwood trees. There are scientists who study plants. They find new ones all the time. They divide plants into two main groups: flowering and nonflowering. Flowering plants make up about 90% of all plants.
There are many different kinds of plants. The first plants were small and did not flower. Over time, the variety of plants grew. Today, there are about 400,000 types of plants. They range from simple ferns to enormous redwood trees.
Botanists are scientists who study plants. They discover new ones all the time. Botanists divide plants into two main categories: flowering and nonflowering. Flowering plants make up about 90% of all plants. They produce seeds that are protected by a hard casing.

There are many kinds of plants. The first plants were small and did not flower. Over time, the variety of plants grew. Today, through the process of Evolution, there are some 400,000 plant varieties ranging from simple ferns to enormous redwood trees. Botanists, the scientists who specialize in studying plants, discover new ones all the time. To bring order to the incredible variety, botanists divide plants into flowering and nonflowering categories. About 90%of all plants are flowering. They produce seeds that are protected by a hard casing. Nonflowering plants, like ferns and mosses do not produce seeds. They produce spores. Conifers are nonflowering plants that do produce seeds. However, their seeds are not enclosed. They are not protected by a hard casing.

The Seed
Seeds need water, sunlight, soil and warmth to grow. Inside the seed is a tiny plant. It has a root, a shoot and “seed leaves” to use for food. A seed’s hard coat keeps the young plant safe. As a seed takes water from the soil, it comes alive.

A seed’s hard coat keeps the tiny plant safe from damage. As the seed takes water from the soil, the coat cracks open. The seed springs to life. It germinates. Then its tiny root pushes down into the soil and its shoot stretches toward the sky. It is now called a seedling.

The tiny plant is called an embryo. When the embryo germinates, its tiny root pushes down into the soil. Plants can sense gravity and so know which way is down. Next the plant sprouts. A shoot stretches toward the sky and leaves begin to open on the stem. The young plant is called a seedling.

Seeds need water, sunlight, soil and warmth to grow. They contain a tiny plant protected by a hard outer coat. The perfectly packaged young plant is called an embryo. The embryo has a root, a shoot and the nutrients it needs to grow. A seed lies dormant until it detects moisture and warmth. It will then absorb water from the soil and spring to life. It will germinate. As the seed coat cracks open, a tiny root pushes down into the soil. Plants can sense gravity and so know which way is down. Next, the shoot will stretch toward the sky and leaves will open on the stem. This young plant is classified as a seedling.
