Detailed explanation-1: -Parenchyma cells and the meristematic cells are the living cells in the plants. Meristematic cells are however restricted to certain locations of the plant body. The rest of the living parts of the plants are therefore made of Parenchyma cells, which makes it the most abundant form of tissue in the plant body.

Detailed explanation-2: -The embryo itself is made up of two distinct tissues, the cotyledons and the embryo axis. The cotyledons differentiate into nutrient storage organs and the embryo axis into a miniature plant with a shoot and root meristem, which will progress into quiescence as the seed matures.

Detailed explanation-3: -Gymnosperms are vascular and they are phanerogams as they produce seeds.

Detailed explanation-4: -Primary meristematic tissue is derived directly from the meristem of the embryo. Secondary meristems are formed secondarily from permanent tissue.
