PowerPoint Presentation: 

What Is a Plant? What are the main kinds of plants? What are flowering plants? What are the main parts of plants? How do plants grow? Where do seeds come from?

PowerPoint Presentation: 

They grow on mountains and in deserts. They grow in freshwater lakes and streams. They grow in the heat of the tropics and in places covered with snow. They even grow in the salt water of the ocean. What are they? Plants, of course ! PLANTS NEXT

PowerPoint Presentation: 

Plants are one of the five main groups of living things. These groups are called kingdoms. The plant kingdom includes such living things as grasses, trees, ferns, bushes, and flowers. Plants vary greatly in size and shape. Some plants are so small they can hardly be seen. Other plants tower above the land. The giant sequoia trees of California are one of the largest living things on Earth. They can grow to heights of nearly 300 feet (90 meters)! Just like animals, plants are made up of tiny structures called cells. But unlike animal cells, plant cells are surrounded by a stiff material called cellulose. Most animals move around and eat other things. Plants are different. Plants that grow on land usually stay in one place and make their own food. Most plants are green because they have a green chemical called chlorophyll. Plants are different from mushrooms and other fungi. Fungi do not have chlorophyll. BACK

PowerPoint Presentation: 

Almost all the members of the plant kingdom are seed plants. They grow from seeds. Most seed plants are flowering plants, or angiosperms.But there are some groups of plants that do not grow from seeds. Botanists call these groups bryophytes, ferns, lycophytes , and horsetails . What are bryophytes ? What are ferns ? LYCOPHYTES What about Horsetail ? NEXT

PowerPoint Presentation: 

any spore-bearing vascular plant that is one of the club mossess and their allies, living and fossil. BRYOPHYTES nonflowering simple plant: a nonflowering plant, often growing in damp places, that has separate gamete-bearing and spore-bearing forms. FERNS plant without flowers: a plant that has roots, stems, and fronds, but no flowers, and reproduces by means of spores. HORSETAILS nonflowering hollow-stemmed plant: a nonflowering plant that has a hollow jointed stem, tiny thin leaves, and spore-producing cones at the top of the stems. LYCOPHYTES BACK

PowerPoint Presentation: 

Flowering plants make seeds that are inside a covering. Angiosperm , the name for flowering plants, means “enclosed seed .” FLOWERING PLANTS Angiosperm flowering plant: a plant in which the sex organs are within flowers and the seeds are in a fruit. BACK

PowerPoint Presentation: 

A plant has three main parts: roots, stems, and leaves. Roots anchor the plant in the ground and absorb water and minerals from the soil. Stems hold the plant up and move water, minerals, and food up and down the plant. Leaves make food for the plant from sunlight, air, water, and minerals. The plant uses this food to grow. Main parts of the Plants:

PowerPoint Presentation: 

ROOTS Roots Roots serve a variety of functions, among them storage, collection of water and nutrients, and support. BACK

PowerPoint Presentation: 

STEMS STEMS The stem of a plant provides pathways for the distribution of water and nutrients between the roots, leaves, and other parts of the plant. BACK

PowerPoint Presentation: 

As the primary photosynthetic organs of plants, leaves have many specialized forms that accommodate the nutritional needs of each particular plant. In addition, leaves have adaptations for defense, predation, pollination, climate, and other aspects of the environment . LEAVES LEAVES BACK

PowerPoint Presentation: 

Most plants grow from seeds. Seeds need soil, water, and light to grow. A bean is a seed. You can make a bean plant grow. Here’s how. Put a bean in a paper cup filled with soil. Set the cup near a window where there is plenty of sunlight. Water the bean often. A root will grow downward from the bean. A green shoot will start to grow upward from the bean. Soon you will see leaves start to grow out of the shoot, or stem. Wind and water may carry some seeds far from the plants that made them. Sometimes seeds are “planted” by animals that eat fruit. Apples, peaches, and cherries are examples of seed-bearing fruits that animals like to eat . How do plants grow ? BACK

PowerPoint Presentation: 

WHERE DO SEEDS COME FROM? Many kinds of plants have male and female parts. These plants reproduce, or make seeds, sexually. In flowering plants, the male and female parts are in the flowers. In pine trees and other conifers, the male and female parts are in the cones. Conifers have male and female cones. The male part of a flower is called the stamen. It gives off a powdery substance called pollen. The female part is called the pistil. An egg forms in the pistil. Pollination occurs when some of the pollen gets to the pistil. A pollen grain joins with an egg. When this happens, a seed begins to grow. In some species, the pollen and egg can come from the same plant. In other species, they must come from different plants. But how does pollen move? Insects, wind, and water can all help move the pollen. Have you seen bees or butterflies around flowers? Bees and butterflies like to drink nectar from the flowers. As they enjoy their tasty treat, some of the pollen sticks to their bodies. They carry it with them to other flowers, leading to pollination. NEXT
