Apex

  • Tip of leaf


Axil

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


Axillary bud
Axillary Bud

  • A bud that develops in the axil.


Flower
Flower

  • The reproductive unit of angiosperms.


Flower stalk
Flower Stalk

  • The structure that supports the flower.


Internode
Internode

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


Lateral shoot
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
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
Root Types

  • Fibrous Root

  • Taproot

  • Storage/Tuberous Root


Root cap
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
Tap Root

  • Main root of some plants

  • Extends straight down under the plant


Terminal bud
Terminal Bud

  • Bud located near the apex of the stem.
