plants

• Non- flowering or non seed forming plants – produces pores for propagation
• Gymgiosperms – seeds are expose or naked, meaning they are not enclosed within fruits. They do

  not produce fruits, instead they form cones.
• Angiosperms – seeds are found within fruits.
• lateral meristems- they are responsible for the secondary growth of plants
• apical meristems - they are responsible for the primary growth of plants
• dermal system consists of the epidermis, or outermost layer, of the plants body. It forms the skin of the plants, covering the leaves, flowers, roots, fruits, and seeds.
• The vascular tissue system consists of two kinds of conducting tissues: the xylem, responsible for conduction of water and dissolved mineral nutrients, and the phloem, responsible for conduction of food. The

  xylem also stores food and helps support the plants.
• Tracheids -are long and thin straws with little holes,
• Vessels are big and wide straws
• parenchyma, is found throughout the plants and is living and capable of cell division at maturity. carry out many

  specialized physiological functions—for example, photosynthesis, storage, secretion, and wound healing. primary walls are present, and these are uniformly thickened.
• Collenchyma, is made up of cells with

  unevenly thickened primary cell walls. pliable and functions as support tissue in

  young, growing portions of plants.
• Sclerenchyma tissue, consists of cells that lack protoplasts at maturity and that have

  thick secondary walls usually containing lignin. Sclerenchyma tissue is important in supporting and

  strengthening those portions of plants that have finished growing.
• roots anchor the plants substrate and to absorb water and minerals.
• The root hairs increase the surface area of the roots and serve as the surface through which water and

  nutrients are absorbed.
• STEMS- Are usually above ground, grow upward, and bear leaves, which are attached in a regular pattern at

  nodes along the stem.
• Leaves are usually flattened blades. The primary photosynthetic organ of most plants.
• The leaf blade is connected to the stem through a narrowed portion called the petiole
