Study Notes

Germination and Dormancy

Dormancy is the inactive period prior to germination, crucial for seed viability and timing of growth.

Plant Tissues

Phloem is responsible for transporting nutrients but is not synonymous with wood; wood primarily consists of xylem.

Reproduction in Plants

Sexual reproduction involves the fusion of sperm and egg cells, resulting in genetic variation and diversity.

Root Structure

The apical meristem refers to the growth region at the root tip, essential for root development and protection.

Wood Structure

Sapwood is the younger, active part of a tree that conducts water, while the older, inner wood primarily provides structural support and is referred to as heartwood.
