Introduction:
The roots are mostly the first structure to form from seed. It involves itself in the absorption of minerals and water from the soil for transportation to the other parts of plants. The structure of the root is composed of a root cap that has parenchyma cells for the protection of root tissue during its growth. The root cap hasmany layers like the epidermal layer and cortex. It is made of ground tissuesand found between the epidermis and vascular tissue of the root. The inner boundary of the cortex is the endodermis; this is a part of the cell wall and consists of a waterproof strip termed as a Casparian strip. The next layer of the root cap is pericycle found next to the epidermis towards the center of the root, this tissue involves in the formation of lateral roots.
Answer to Problem 6STP
Correct answer:
The correct answer is option (B).
Explanation of Solution
Explanation/justification for the correct answer:
Option (B) The part of the root in 2 is the primary meristem. It is the zone of cell division. It is also termed as the elongation zone of roots and is involved in the increase of the length of the root.So, the correct answer is option (D).
Explanation for incorrect answer:
Option (A)The part of the root represented in this is the root cap. It is involved in the protection of root tissue during its growth. So, this is an incorrect option.
Option (C)The part of the root represented in this is the vascular cylinder. It is involved in the transportation of food, water, and other substance throughout the plant.So, this is an incorrect answer.
Option (D) The part of the root represented in this is the epidermis. It is the dermal part of the roots that protect it from environmental stress and pathogen.So, this is an incorrect answer.

- Question #4: Assume you are able to use CRISPR to create an allele that will convert a cross-pollinated, sexually reproducing crop plant into an obligate apomict. 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?
