plant structure bi Seed Plant Overview: The plant body consists of two basic parts--- the shoot system and the root system Shoot system is above ground and includes organs such as leaves, buds, stems, flowers, and fruits The functions of the shoot system include photosynthesis, reproduction, storage, transport, and hormone production The root system is below ground and includes roots as well as modified stem structures such as tubers and rhizomes The functions of the root system include anchorage, absorption, storage, transport, and production of certain hormones Seed plants contain 2 types of vascular tissue (xylem & phloem) to help transport water, minerals, & food throughout the root & shoot systems Plant cells have several specialized structures including a central vacuole for storage, plastids for storage of pigments, and a thick cell wall of cellulose Plant cells are all box-shaped in appearance Meristems: Root Tip with Meristems Specialized Plant Cells: Parenchyma Cells Collenchyma cells Dermal Tissue:
Biology for Kids: Flowering Plants Flowering plants are a type of vascular plant that produces flowers in order to reproduce. Flowering plants produce seeds within a fruit. The scientific name for flowering plants is angiosperms. Life-cycle of a Flowering Plant Flowering plants follow a specific life cycle. Seed - They begin their lives as seeds. Diagram showing the life-cycle as well as structure of a flower Flower Flowers are the reproductive organs of the flowering plant. The main structures of a flower include: Sepal - The sepal is a support structure for the petal. Fruits are a way which many plants spread their seeds. Seed The seed is the embryo of a plant. Seeds may be dispersed by a number of ways including air, water, and animals. Parts of an avocado seed Pollination In order for an ovary to become a seed, it must receive pollen.

Biology for Kids: Plants Science >> Biology for KidsWhat are plants? Plants are living organisms that cover much of the land of planet Earth. You see them everywhere. They include grass, trees, flowers, bushes, ferns, mosses, and more. Plants are members of the kingdom plantae. What makes a plant a plant? Here are some basic characteristics that make a living organism a plant: Most plants make their own food through a process called photosynthesis. Plant cells are composed of rigid cell walls made of cellulose, chloroplasts (which help with photosynthesis), a nucleus, and large vacuoles filled with water. Click the picture for a larger view Energy from the Sun One of the most important functions of most plants is photosynthesis. Types of Plants There are many different types of plants. Vascular - These plants have specific tissues that help to move materials such as water through the plant. The three basic parts of most vascular plants are the leaf, the stem, and the roots.
