PLANTS

Matthew Gillis 8A

Overview

Plants are living organisms which grow all over the world and have adapted to various types of terrain and environment. Plants use a cycle system of gathering minerals, creating energy, and releasing it. There are many parts to all plants, and many types of plants as well.

Roots

• The root of the plant has two uses. To anchor the plant into the ground, and to get water and minerals from the soil.

• The roots are the long, tentacle-like branches at the bottom of a plant. These roots have small hairs all over them to collect water and minerals from the soil, and branch out to keep the plant stable.

The Root System

Stem

• The stem is a key part of the plant, it is what carries water and nutrients to and from the leaves.

• The stem has two types of tubes in it, Phloem and Xylem.

• Phloem carries food from the leaves to the rest of the plant, and Xylem carries water and minerals through the plant.

Leaves

• The leaves are the life source of the plant. The leaves create food through a process called photosynthesis so the plant can grow. The leaves take in water, and carbon dioxide and in the presence of sunlight and nutrients, creates glucose. Glucose is the plants food, but it also create oxygen as a bi-product which is then released into the air at night.

Leaves

• The leaf is a very complex system which takes years of studies to basically understand the Calvin Cycle and the structure of the leaf. The leaf lets air in through the stomata, which is surrounded by guard cells to control intake. When the oxygen reaches the plant cell’s chloroplast which harvest’s the sunlight, an the water is brought from the Xylem, photosynthesis can begin.

Leaves

Flowers

• Flowers come from nodes, which grow into flowers, leaves, roots, or stems, depending on the node. The flower is used for reproduction of the plant. If it is a fruit, it will fall and the seeds will grow, or it will be sexually reproduced.

Flowers

Other Parts

• Apical Bud: The bud or node at the tip of a plant

• Internode: The space of stem between two nodes.
