Describe the characteristics and classification of seedless vascular and nonvascular plants

Answers

Answer:

Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant.

1. These lignified tissues are also called vascular tissue and consist of water-conducting xylem tissue and food-conducting phloem tissue.

2. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances.

3. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.

4. The root is a true root that enables the plant to anchor onto the soil and gets nutrients from it.

5. The leaves are broad and have stomata that work for gas exchange and support transpiration.

6. The stem of vascular plants is multilayered with vascular tissue that helps in the protection and conduction of food and water.

7. The arrangement of these issues might be different in a different group of plants as it depends on the pattern of division of cells.

8. The xylem is composed of non-living matter, tracheids, and vesicles, hardened by lignin that provides a stiff structure to the tissue. 9. The phloem, on the other hand, contains living sieve elements that are not lignified.

10. Vascular plants are capable of surviving on land due to their ability to transport food, water, and mineral to different parts of the plant by creating pressure through the tissues.

11. Besides, they also have several modifications that facilitate their survival on land.

12. Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores.

13. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substances to all parts of the body via vascular tissue.

14. It is believed that vascular plants are a more evolved version of non-vascular plants and thus came later in the evolutionary history.

15. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams.

16. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. These plants belong to the group Pteridophyta.

17. The higher vascular plants are numerous and extremely diverse and are further divided into different subgroups.

18.Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses, etc.

Answer:

Definition of nonvascular plant

: a simple, low-growing, nonflowering plant (such as a moss or liverwort) that lacks specialized conducting channels for transporting water and nutrients

vascular plants have lignified tissues for conducting water and minerals throughout the plant.

Animal and plant cells both contain the mitochondria to perform cellular respiration in order to get energy from the food. 3. and 4. Plant cells have a rectangular shape structure and animal cells typically show round or spherical shape. 5. Both cells are eukaryotic cells so they carry the nucleus. 8. both cells have a cell membrane surrounding the other organelles. 9. Cell wall present in plant cells and not in animal cells. 10. A large central vacuole is present in the plant cell that performs various roles including the storage of water and nutrition.

11. In the given diagram The illustration B is a plant cell as it has a rectangular shape with a cell wall around the cell membrane.

The following case study is a paraphrase from "Good Clinical Practice. Standard Operating Procedures for Clinical Researchers" (Kolman, J., Meng, P. and Scott, G. editors; John Wiley and Sons publishers, 1998):

“While a study subject and a relative were walking in town one day during the summer, a hanging flower basket fell on a study subjects head, resulting in the study subject falling down and becoming unconscious. The subject’s relative called for an ambulance. On arrival at a local hospital’s Emergency Department, in which the subject regained consciousness but could not recall the event, a x-ray revealed a fractured skull. The subject’s consciousness level at this point was deteriorating and after further tests a subdural hematoma was diagnosed, which was evacuated under general anesthesia. Postoperative recovery was uneventful and progressing well until day four, when the patient developed acute dyspnea (shortness of breath) at rest during visiting time. An emergency lung scan was performed that confirmed a diagnosis of pulmonary embolism. The study subject was anticoagulated and was eventually discharged from the hospital”

1. What is/are the AE/s in the case study?

2. Are there any AEs that are "serious"? If "yes", list them and state why they are serious.

3. What are your thoughts about the AE(s) being related to the study drug (NOTE: we do not know whether the subject is on active drug or placebo)?

A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
D)
The organism was able to transport water through specialized veins.

A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:

Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

The organism to be identified

Explanation:

To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
