Plant Anatomy
Plants are part of the kingdom Plantae. They are living organisms that convert energy from sunlight into chemical energy during photosynthesis.
Structural Divisions: ● Flower anatomy
-Calyx, Corolla, Androecium, and Gynoecium
● Leaf anatomy -Epidermis, stomata and Palisade cells
● Stem anatomy -Stem structure and vascular tissues, buds and shoot apex
● Fruit/seed anatomy -Structure of the Ovule, Seed, Pericarp and Accessory fruit
● Wood anatomy -Structure of the Bark, Cork, Xylem, Phloem, Vascular cambium, Heartwood and sapwood and branch collar ● Root anatomy - Structure of the Root, root tip, endodermis
Functions:
Axil - angle between the upper side of the stem and a leaf, branch, or petiole
Axillary bud - bud that develops in the axil
Flower - reproductive unit of angiosperms
Flower stalk - structure that supports the flower
Internode - area of the stem between any 2 adjacent nodes
Lateral shoot (branch) - offshoot of the stem of a plant
Leaf - an outgrowth of a plant that grows from a node in the stem; primary function is to convert energy from sunlight into chemical energy (food) through the process of photosynthesis
Node - 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 that attaches the leaf to the plant
Root - a plant structure that obtains water and dissolved minerals from the soil, stores energy, and provides support for the plant
Root cap - a structure at the ends (tips) of the roots that covers and protects the apical meristem (the actively growing region) of the root
Stem (a.k.a. the axis) - main support of the plant; carry water and food from place to place within the plant itself
- Outer layer = epidermis
- Inner layer = cortex
- Central zone =pith
Tap root - the main root of some plants; extends straight down under the plant
Terminal bud - a bud located at the apex (tip) of the stem; have a special tissue, called the apical meristem, which consists of cells that can divide indefinitely
