Structure of a Dicotyledon Seed
Dicotyledon seeds are a group of over 1,75,000 plant varieties, from flowers to trees, grouped under the species Magnoliopsida. The presence of two lateral cotyledons differs from the dicotyledons. To initiate plant growth before the start of photosynthesis, starch, fat, and protein are retained in cotyledons. The germination of the dicotyledon seed may be hypoglycaemic or epigeal. Dicot leaves are simple or complex in appearance, with dorsiventral symmetry, net or reticulate venation, and often sharp or broken edges. Stomata are located at the lower edge of the leaf. The dicots have a taproot system, a firm stem, and a vascular system which is wrapped in rings.
Examples of Dicotyledon
Oak, carrots, radishes, almonds, bell peppers, peas, etc.
Seed
The difference between dicotyledons and monocotyledons seeds is the number of cotyledons found in an embryo. The seed is an initial stage of plant growth, where differences between monocot (mono means one) and dicot (di means two) occur. Cotyledons are used to refer to the first seed leaf in an embryo. If one seed leaf is present, the plant will be classified as a monocot and if two leaves are present, it’s dicot. There are further classifications for monocotyledons and dicotyledons within angiosperms based on the presence of an embryo inside the seed.
