Answer:

Matter

-Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size. The most familiar examples of material particles are the electron, the proton and the neutron. Combinations of these particles form atoms.

Fertilization

-Fertilization can be defined as the union of two haploid gametes, the spermatozoa and the oocyte, hereto referred to as egg, to restore the diploid state, form a zygote through the process of egg activation, and commence a series of mitotic divisions that results in cell differentiation and embryo development.

Land breeze

-A land breeze is a local nighttime and early morning wind that occurs along coasts and blows offshore (from the land out to sea). It arises at sunset when the sea surface is warmer than the adjacent land due to the land having a lower heat capacity and cooling off faster

Cotyledons

-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.
