Introduction :
Along with cell wall in plant cell there are many different cells that have specific function and form tissue. There are three types of cells that form the plant tissues. They function together to provide food production and storage; give flexibility, support, and strength to the plants. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have many other function like food storage, gas exchange, photosynthesis, and protection. The next cell is collenchyma; they are cylindrical in shape and give support around the cell. They consist of unevenly thickened cell walls. This cell retain the ability to process cell division ones get matured. The third cell is the sclerenchyma; they are lack of cytoplasm and other living components ones get mature. They have thick and rigid cell wall; they involve in providing support to the cell and also help in transportation of materials within the cell.
Answer to Problem 5A
Correct answer :
The correct answer is option (A) apical meristem.
Explanation of Solution
Explanation/justification for the correct answer :
Option (A) apical meristem. Apical meristem is a type of meristematic tissue that found in the tip of the stems and roots. The cell division takes place in the tips of roots and stems. It increases the length of the plants and is considered as primary growth. So, the correct answer is option (A).
Explanation for incorrect answer :
Option (B) vascular tissue. Vascular tissue is the type of tissue that is involved in the transportation of food, water, minerals, and nutrients throughout the plant. They are divided into xylem and phloem. So, this is an incorrect option.
Option (C) dermal tissue. The epidermis and the guard cells are two types of cells that are located in the epidermis of the plants that is originated from the dermal tissue. They are involved in forming a contact of the plants with the external environment. They are found in the outer portion of the roots, stems, and leaves. So, this is an incorrect answer.
Option (D) lateral meristem. The lateral meristem is the type of tissue that is involved in the increase in the diameters of the roots and stem. It is considered as secondary growth. So, this is an incorrect answer.

Your edited obligate apomict plants retains all the CRISPR "machinery" necessary to convert the "sexually reproducing" allele to the "obligate apomict" allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forward
