Plant Parts and their Functions

Apex Tip of leaf

Axil The angle between the upper side of the stem and a leaf, branch or petiole.

Axillary Bud A bud that develops in the axil.

Flower The reproductive unit of angiosperms.

Flower Stalk The structure that supports the flower.

Internode The area of the stem between any two adjacent nodes.

Lateral Shoot An offshoot of the stem of a plant.

Leaf Outgrowth of a plant that grows from a node in the stem Most are flat and contain chloroplasts

Leaf Main function is to convert energy from sunlight into chemical energy (food) Uses photosynthesis for accomplish this

Node The part of the stem of a plant from which a leaf, branch or aerial root grows Each plant has many nodes

Petiole A leaf stalk It attaches the leaf to the plant

Root Obtains food and water from the soil Stores energy Provides support for the plant

Root Types Fibrous Root Taproot Storage/Tuberous Root

Root Cap A structure at the end (tip) of the roots Covers and protects the meristem – Meristem-actively growing region of the root

Stem Main support of the plant Also known as the axis

Tap Root Main root of some plants Extends straight down under the plant

Terminal Bud Bud located near the apex of the stem.
