adventitious roots many roots grow out from the base of the stem; tap root the embryo root grows large and side roots grow from it; parallel veins veins run side-by-side for the length of the leaf
unit 7 In this unit you will:
• identify and describe visible differences between monocotyledons and dicotyledons
• grow monocot and dicot seeds to observe and record differences in growth patterns.
Before we start
Angiosperm plants have roots, stems, leaves, flowers, fruits and seeds.
Angiosperms are divided into two groups: monocotyledons or monocots that have seeds with one seed leaf or cotyledon, and dicotyledons or dicots that have seeds with two seed leaves or cotyledons .
Differences between monocotyledon and dicotyledon plants
Plant part Monocotyledons
1. Roots Monocots have many adventitious roots which grow from the base of the stem.
Dicotyledons
Dicots have a central root, the tap root, from which lateral roots grow.
Biodiversity: Differences in angiosperms
Tese are adventitious roots
Tap root system
monocotyledon the seed has one cotyledon; cotyledon a seed leaf; dicotyledon the seed has two cotyledons which store food for the growth of the embryo plant
