Because the number of seed leaves is a good differentiation of the types of plant.
The trillium is a woodland wildflower native to South America. It belongs to the Liliaceae family and is classified as a monocotyledon.
Plants are classified as flowering(angiosperms) or non flowering(gymnosperms).
Yes, sunflowers are dicotyledon. They are flowering annual plants and have two parts to their seeds rather than just one.
The words monocotyledon or dicotyledon describe the plant not the leaves. So you can't say a leaf is a mono or dicotyledon. A sycamore tree is a dicotyledon. Most trees are, plants likes grasses, grains palms are monocotyledons
linneus
One of various flowering plants, such as grasses, orchids, etc having a single cotyledon in the seed.
Dicotyledons are groups of flowering plants whose seed has two embryonic leaves. Examples of dicotyledon seeds are oaks, beans, legumes, apples and olives.
it's dicotyledon.--> No! Pine is a gymnosperm ("naked seed"; no ovary), and thus the terms dicotyledon (dicot or eudicot) and monocotyledon (monocot) do not apply to conifers like Pine. The terms "monocotyledon" and "dicotyledon" (or more accurately "eudicot") only apply to the angiosperms (flowering plants containing ovaries/"vessels"). Pine is NOT an angiosperm, thus this these terms DO NOT apply to Pine (or any other conifers).
flowering plants
A plant with seeds is a flowering plant and is called an angiosperm.
Cotyledons
Neither, because it is not an angiosperm (flowering plant). A monocot (monocotyledon) is an angiosperm with one cotyledon (seed-leaf) while a dicot (dicotyledon) is an angiosperms with two cotyledons (seed-leaves). Western red cedars are gymnosperms. A gymnosperm has "naked seeds" meaning that the seeds (ovules) are not found in an ovary but rather on leaves, scales or in cones.
