What is a plant?
Plants are living organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae.

Roots are like straws. They absorb water and minerals from the soil. Tiny root hairs stick out of the root to help the root absorb. Roots help to secure the plant in the soil so it does not fall over. Roots also store extra food for future use. The Stem on a plant do many things. They support the plant, just like the Roots. They conduct water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts. Most plants food is made in their leaves. Leaves are designed to capture sunlight which the plant uses to make food through a process called photosynthesis. Flowers are the reproductive part of most plants. Flowers contain pollen and tiny eggs called ovules. After pollination of the flower and fertilization of the ovule, the ovule turns into a fruit. Fruit provides a covering for seeds. The seeds then contain new plants and most of the seeds turn into fruit.
What is a seed?
A seed is a flowering plant's unit of reproduction. A seed is capable of developing into any such plant.

Seeds are produced within the fruit of a plant. A genetic seed then waits for the right condition to develop. The development of a seed is called germination. The seed coat is the protective covering of a seed. The scar where the seed was attached to the fruit is the Hilum. Pollen enters the seed through the micropyle. Inside the seed, the epicotyl forms a tiny root. The baby stem is formed by the hypocotyl. The first leaves are formed by the radicle. The cotyledon provides food for the new plant.
Micropyle - The Micropyle is a tiny opening in the seed coat where pollen would enter the seed and then causes it to mature.
Hilum - Hilum is the scar on the side of the seed, it indicates the place where the seed was attached to the fruit.
Seed Coat - Seeds are covered by a protective covering called a Seed Coat.
Cotyledon - The cotyledon is the large area of the seed. It provides food for the new plant and in many plants it also forms two seed leaves.
Epicotyl - The epicotyl takes the shape of a tiny leaf, once formed the parts then grow quickly.
Hypocotyl - The hypocotyl grows into an early stem.
Radicle - The radicle is where tiny roots are formed.
