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. Similarly the transportation of nutrients, water, and other substances in plants are carried out by tissue like xylem and phloem.
Answer to Problem 4A
Correct answer :
The correct answer is option (C) xylem.
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) xylem. The xylem tissue is made of dead cells, involved in the transportation of water and other nutrients, and composed of fibers and tracheids. So, the correct answer is option (C).
Explanation for incorrect answer :
Option (A) epidermis. The epidermal cell provides protection to the plants from the environment, found in the epidermis of stem, and leaves, consist of chloroplast. So, this is an incorrect option.
Option (B) parenchyma. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have other functions like food storage, gas exchange, photosynthesis, and protection. So, this is an incorrect answer.
Option (D) phloem. The phloem tissue is made of living cells, involve in transportation of food and organic materials. The phloem tissue is composed of fibers, sieve cells, sieve tubes, phloem parenchyma, and companion cells. 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?
