What is a Vascular Plant? Vascular plant is a tube-like tissue that transports water and nutrients, such as, stems, roots and leaves. Xylem is where there is water and Phloem conducts other things, like food.
Vascular divides into two groups. One group is where seed are produced and the other one is seedless.
What is a Non Vascular plant? Do not have a tube to transport water or nutrients. They grow short, don’t travel quickly. Also they have to live in damp and shady areas.
Three types of tissues: Dermal Tissue is an epidermis outer layer of a plant that protects any infection or damage that is coming from outside. It covers part of a plant like the leaves, roots, stems, flowers, fruits and seeds are found here.
Vascular Tissue is a plant tissue that transports water and dissolved material through a plant. Also, it is the center of the plant and it provide support. The two types of vascular tissue are xylem and phloem. Xylem transports water through the plant and it is made up of tracheids and vessel elements. These two provide pathway for water and mineral to travel from the roots to the leaves, but found in different areas. Tracheids are found in all vascular plants, when vessel elements are found only in Angiosperms. Phloem is responsible for transporting sugar and from translocation.
Angiosperms become monocotyledons where there are parallel veins and dicotyledons that have netted veins. Cotyledon is a seed leaf in a plant's embryo; used as an organ for food storage.
Ground Tissue provides storage and supports the plants. There are three types of cells that makes up ground tissue. 1. Parenchyma is where storage takes place and it controls photosynthesis. 2. Collenchyma provides mechanical support and elasticity. 3. Sclerenchyma is mechanical and protective.
The organs of a plant: leaves, roots stems, and flowers. Plants need soil, water, sunlight, and air.
Leaves are one of the organs that go through photosynthesis. Blade, veins, petiole, node, and midrib are part of a leaf.
Leaves can be simple or compound. The compound leaves have two or more blades called leaflets and the leaves can be pinnate or palmate. That are linked together to the main petiole.
Water Transport The structure in the leaf that keeps it alive is the roots, root hairs,xylem vessels. Osmosis is the movement of water from area of high concentration to an area of low concentration through a semi-permeable membrane.
The Plant Growth The mechanism growth in plants are called apical meristems where there is a primary growth in height and happens constantly at the tips of shoot tips. The other one is called lateral meristem that occurs in the secondary growth and focuses on the width more because the process is a little more detailed. Primary growth is where apical meristems takes place.
