What is a cotyledon embryo?
Either the nutrients surround the embryo in a tissue known as endosperm, as in a corn seed, or the nutrients are stored in leaf-like structures known as a cotyledons which are part of the embryo, as in bean seeds.May 14, 2020
Is cotyledon the same as embryo?
Cotyledon refers to the significant part of the embryo found within the seed. It is the first and the tender leaf that emerges when the seed germinates. It is also called the storage unit of a seed, as it provides nutrients to the different parts of an embryo.
What is cotyledon in embryo?
cotyledon. cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
What is a plant embryo called?
The germ is the plant embryo which would form the new plant if germinated and is characterized by a high lipid and protein content.
Is a plant embryo a zygote?
Abstract. Each plant starts life from the zygote formed by the fusion of an egg and a sperm cell. The zygote gives rise to a multicellular embryo that displays a basic plant body organization and is surrounded by nutritive endosperm and maternal tissue.
Do plants have embryo?
Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed. The seed protects the embryo and stores food for it.Feb 2, 2014
What are the types of embryo in plants?

Why two cotyledons in a seed are embryonic leaves?
1 :- Cotyledon is the most important part of the embryo or the growing seed, cotyledon provides nutrition to the embryo for its growth and development. 2 :- These cotyledons are also known as the embryonic leaves and they are the first leaves of the embryo which develops during the germination of the seed.
