What contain two cotyledons within a seed?
If two cotyledons appear in a germinating seed, the plant is said to be dicot or dicotyledonous. These plants have a whorl like a flower arrangement and their leaves have networks of veins. So, the correct answer is B. Dicots.
Which seeds have two seed leaves inside the seed coat?
Dicots (left) have two cotyledons. Monocots, such as corn (right), have one cotyledon, called the scutellum; it channels nutrition to the growing embryo.
Do all seeds have two cotyledons?
No,all seeds do not have two cotyledons. Monocots have only one cotyledon.
What 2 things do seeds contain?
A seed is the part of a seed plant which can grow into a new plant. It is a reproductive structure which disperses, and can survive for some time. A typical seed includes three basic parts: (1) an embryo, (2) a supply of nutrients for the embryo, and (3) a seed coat.
Does maize have two cotyledons?
A monocot will produce seeds with a single cotyledon, and a dicot will produce seeds that have two cotyledons. Examples of dicot plants that have two cotyledons would be beans, daisies, tomato plants, and oak. Maize is a monocot plant; therefore, maize seeds have a single cotyledon.
What are cotyledons what is their function in a seed?
Cotyledon is the seed leaf within the embryo of a seed. This is because they supply food to the baby plant coming out during the seed germination. These stored nutrients are supplied to the seedling during germination. Sometimes, the cotyledons may become photosynthetic in function during the process of germination.
Which seeds have cotyledons?
monocots
Angiosperms (flowering plants) whose embryos have a single cotyledon are grouped as monocots, or monocotyledonous plants; most embryos with two cotyledons are grouped as eudicots, or eudicotyledonous plants.
Which of the following has two cotyledon?
Flowering plants whose embryos have a single cotyledon are grouped as monocots, or monocotyledonous plants; embryos with two cotyledons are grouped as dicots, or dicotyledonous plants.

How many cotyledons does castor seed have?

Which is type of seed has two cotyledons?
Monocots are seeds that have only one cotyledon, while dicots are plants with two cotyledons. The cotyledons are formed during the process of embryogenesis along with the roots and shoots of the plant prior to germination. Subsequently, question is, what type of plant has two leaves? dicotyledonous
How many cotyledons does a monocot seed have?
A cotyledon is part of the embryo within the seed of a plant. Monocots are seeds that have only one cotyledon, while dicots are plants with two cotyledons. The cotyledons are formed during the process of embryogenesis along with the roots and shoots of the plant prior to germination.
Where are the cotyledons found in a plant?
Cotyledons are present in every seed. These are formed within the seed with the endosperm. These are classified plants based on the number of cotyledons present. It is however true that the seedlings of some flowering plants do not have any cotyledons at all.
What are the characteristics of a dicotyledonous seed?
Characteristics of Dicot seeds: 1 It contains two cotyledons. 2 The outer covering of dicot seed is the seed coat, which has two layers called outer testa and inner tegmen. 3 The embryo stays within the seed coat and includes an embryonic axis and two cotyledons. These cotyledons are mostly… More
