Study Notes

Seed Structure

Cotyledons are the seed leaves that provide nutrients to the developing seedling
The seed coat protects the seed from drying out and provides a barrier against pathogens and insects

Root Types

There are two main types of roots: taproots and fibrous roots
Taproots have a single main root that grows downward, while fibrous roots have multiple small roots that spread outward

Plant Stem Functions

Xylem tissue in the plant stem is responsible for transporting water and minerals from the roots to the leaves

Photosynthesis

Most photosynthesis occurs in the chloroplasts of mesophyll cells, typically located in the leaves
