Brad Y


"Hi! Just returned from taking my Praxis computerized and am happy to say that I passed with a 175. The last time I took the test I missed by 1 point. Your tests definitely made the difference for me! The set up was so similar to the test and the types of questions were also similar that I felt very comfortable taking the test (and even finished it early!) I will recommend your site to everyone I know in my major at Lock Haven University!!!!"

Christina G


"I took the praxis math for the very first time recently. I was very confident during the test and I passed with a 182. I've always been good at math but this website really helped me to prepare. Thank you!"

Julie C


"Thanks so much!!! I wouldn't have been able to pass without the help I got from your tests. They are great and so much like the real ones. I think the display and the timing helped reduce my test anxiety as well b/c I became comfortable with the format and it didn't bother me when I went to take the praxis. Your tests are so much like the real thing!! Thanks again!!"

Carol J


"After missing the Praxis 1 test by two points last year, I knew that I had to do something. I signed up for your program and took the 5 test series and kept reviewing the missed questions. It took the fear right out of the test taking ... My heart was pounding really fast, the last few minutes of the official test but I passed. Thank You, it was one of the final steps to receiving my grant money for the CT-3 program and admission into the Watson School of Education. May God Bless you. "

Stacy S


"For last year I have been trying to pass the reading section of Praxis I. I had taken it six times and if I did not pass it this month then I could not take my college courses in education. I went to Google and typed in practice reading tests and your website came up. I clicked on, signed up and took the free test. I knew that I was going to buy a couple of tests after I took that one. I ended up buying four additional tests. This morning (1/10) I took the praxis and passed with a 181. I was ecstatic. I owe it to you guys though because without your tests, I do not believe that I would have passed otherwise. Thank you so much and I will continue to recommend people to your website."

Naomi I


"Hello , I just wanted to drop a note and say thanks. I went through every one of your practice tests and it really paid off because I took the real Praxis Math test today and passed. I will keep passing the word about your Praxis Math website to my fellow classmates in the education department. Again, Thank you very much! Naomi- A future educator :)"

Tamora A


"Thank you! I passed on Dec 29th! My scored went up 10 points! I will recommend your site to all the teachers I know who are struggling w/ math. "

Leigh W


"I passed!!! The consistent practice and experience navigating through the system was incredible! I plan to tell everyone about your program. Once again, I thank you. "

Pam L


"Thank you, thank you, your Praxis Math I can not tell you how much they helped. I passed the test today and I am so happy. Thanks again."

Praxis Biology - Test Reviews Sample Questions

The plant's roots have many functions and are essential to the plant's structure and collection of water and nutrients.  Listed below are many root components, which one is not accurate?





Correct Answer:
the region of fertilization:  cylinder in shape, the region of fertilization in the area in the plant were the sex cells are produced for fertilization and later fertilized and expressed out of the roots.


roots are a crucial component of a plant's anatomy, tasked with several vital functions including anchoring the plant, absorbing water and nutrients, and storing food. the structure of roots includes several specialized regions which contribute to these roles, but the region of fertilization as described in the question is not one of them. let's analyze each component mentioned and clarify which one is inaccurate.

first, the region of cell division, typically located just behind the root cap, is where new cells are produced. these cells are essential for the growth of the roots. this region is characterized by rapid cell division, which contributes to the elongation of the root. in contrast to the claim made in the original statement, the peak times of cell division are influenced by various environmental factors rather than occurring strictly at noon and midnight.

the region of maturation, often referred to as the root hair zone, is another critical area where root hairs develop. these root hairs are extensions of the root's epidermis and significantly increase the surface area for water and nutrient absorption. this region is crucial for the efficient uptake of essentials from the soil, aiding the plant's overall nutrition and hydration.

the root cap is a protective structure located at the tip of the root. it shields the delicate apical meristem (the growing tip of the root) as the root pushes through the soil. the root cap also plays a role in sensing gravity, guiding the roots to grow downwards.

regarding the claim about the region of fertilization, this is not accurate in the context of plant root systems. the description provided suggests a process similar to that found in animal reproductive systems, where gametes are produced and fertilized within the same structure. in plants, sexual reproduction does not occur in the roots. instead, it takes place in the flowers of angiosperms (flowering plants) or cones in gymnosperms. the roots are involved neither in the production of gametes nor in fertilization processes. instead, their primary roles are related to support, storage, and absorption as previously mentioned.

therefore, the statement concerning the "region of fertilization" being a cylinder-shaped area in the roots where sex cells are produced and fertilized is incorrect. this description does not apply to any known structure or function within the root systems of plants. instead, the correct components of root systems include regions like cell division, elongation, maturation, and specialized structures such as the root cap, along with adaptations like pneumatophores (for gas exchange in waterlogged soils), mycorrhizae (symbiotic associations with fungi), and nodules (commonly found in legumes for nitrogen fixation).
