Seed-Producing Plants


1. For starters, gymnosperms produce seeds that are considered “naked,” these seeds are directly exposed to air. Angiosperms on the other hand, produce seeds that are completely covered and protected by either a pod or shell. Both have more specifications, but their seeds are one of the main distinctions between the two.

2.
a. Meristematic tissue is a function that allows the growth of plants by undergoing mitosis. The new cells that produced by mitosis, with the help of merismatic tissue, can begin to grow and generate new parts of the plant that will specialize it to be able to adapt and survive. Merismatic tissue that is found at the roots and tips of leaves help elongate the plant and make it grow bigger with the help of certain plant hormones called auxins and gibberelims.
b. Vascular tissue transports nutrients and water throughout the plant body which circulates food(nutrients) and keeps the plant fully hydrated(water). The Vascular system basically fuels the function of photosynthesis. Some seedless plants such as algae and moss lack vascular tissue which makes surviving on land much more difficult, whereas seed-producing plants have adapted to land better due to their vascular system that makes reproduction much easier(seeds).

3. Meristematic tissues is located in the tips of roots, and stems which are the locations that can help the plant grow larger and grow specialization's. Another kind of merismatic tissue is the vascular tissue which is located throughout the whole plant in order to enable the transportation required for photosynthesis.

4. Xerophytes have specialized root systems that absorb and obtain as much water as available. Not only do xerophytes obtain the required amount of water for survival, but they are specialized with an extensive roots system that absorb more than enough water, so that is can be stored for later. Hydrophytes are less concerned about water, since they are aquatic plants, and focus more on photosynthesis (gas exchanges). Halophytes on the other hand have a high tolerance for the mineral and salt content in the water that they depend on and live off of.

5. Sapwood is made up of many layers of xylem tissues which are still functioning which is the outer layers of the tree, whereas heartwood is the now inactive innermost layers of the tree that have been too clogged up by cellulose. Each of these layers can be determined by the xylem tissues that clearly separate each ring of the tree, which are called annular rings.
