Introduction :
Plants have many different tissues with specific function in different parts. They function together to provide food production and storage; give flexibility, support, and strength to the plants. The plant tissue includes meristematic tissue that involve in producing new cells throughout the lives of a plant, dermal tissue that is also considered as epidermis, it forms cuticles that help to reduce loss of water. Trichomes are the epidermal cells that are hairlike and produce in leaves and stems. It gives the leaves and stems a fuzzy appearance to provide protection against predators, it is also involved in maintaining the optimal temperature keep it cool. Root hairs are other epidermal cells that found in roots, this involve in the increasing the surface area of roots. The next is the vascular tissue involve in the transportation of nutrients, water, and other substances in plants. All the tissues are found in different parts of plants like roots, stems, and leaves.
Explanation of Solution
The leaves of plants are involved in the photosynthesis process and the structures of the leaves are such that it is well adapt to this function. The leaves have a flattened area that is termed as blade, it involves in providing the large surface area. The blades of the leaves are attached to the stem with the help of a stalk that is termed as petiole. The internal structure of a leaf consists of tightly packed cell found instant below the upper epidermis. This portion of the cell is highly exposed to the light; so, most of the photosynthesis process takes place in this cell. This cell has many chloroplasts and made up of palisade mesophyll tissue. Below the palisade layer spongy mesophyll tissue is found, that are rectangular in shape, and loosely packed. The oxygen, water vapor, and carbon dioxide pass through the space on the spongy mesophyll.
The cell where most of the photosynthesis process is takes place is composed of palisade mesophyll tissue. Below the palisade layer spongy mesophyll tissue is found, that are rectangular in shape, and loosely packed.

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
