Host-based firewalls, such as Internet Connection Firewall (ICFâincluded with Windows XP and Windows Server 2003), protect an individual computer regardless of the network itâs connected to. You might need one or the otherâbut most businesses require a combination of both to meet their security requirements.
Monocotyledons (/ËmÉnÉËkÉtÉËliËdÉn, -ËkÉtËliË-/), commonly referred to as monocots, (Lilianae sensu Chase & Reveal) are flowering plants (angiosperms) whose seeds typically contain only one embryonic leaf, or cotyledon.
Upon germination, the cotyledon may become the embryonic first leaves of a seedling. The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous (monocots).he cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed. As these reserves are used up, the cotyledons may turn green and begin photosynthesis, or may wither as the first true leaves take over food production for the seedling.
