Answer:

Cells are the basic structure and unit of life. There are prokaryotic and eukaryotic cells. Prokaryotic cells are very basic, and have no nucleus, few organelles, and are ususally bacteria. Eukaryotic cells are more complex and have nuclei, are larger compared to prokaryotic cells, more organelles, and have emembrane bound organelles. There are plant and animals cells, each have certain organelles that other don't. For example, plant cells have large vacuoles and a cell wall; animal cells have centrioles. Cells are important because they provide strucure for the body, and take in nutrients from food and carry out many important functions, such as protein synthesis, respiration, growth and development, and more. Billions of cells make up a complex organism's body, while a single cell can make up an entire organisms, and carry out all of the needed functions. That's a quick summary of what cells are, and some of the things that they do that make them so important

The diagram shows structures found in a seed plant.

Answer:

provides food for embryo

Explanation:

The structure marked with an X in the figure below is called a stored nutrient reserve.

The seeds are basically formed by an integument (outer part, a stored reserve and the embryo (it is in the center of the seed), the embryo is the main creator of a new plant, for that, it needs a high load of nutrients that is provided by the nutrient reserve. In addition, the stored nutrient reserve protects the embryo from external factors such as solar radiation and freezing.

RNAi-based modification of amylopectin content in wheat occurs through decreased expression of starch-branching enzymes. If the

kicyunya [14]

If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.

Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.

The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.

In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).
