In a humoral or antibody-mediated immune response, specific B cells are stimulated by Helper T cells to help transform into plas
steposvetlana [31]

Answer:

An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).

Explanation:

The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.

The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.

<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.

List and explain the function of four organelles found in eukaryotic cells.<br> HELP NOW !
Elan Coil [88]

Explanation:

Below is a list of organelles that are commonly found in eukaryotic cells.

Organelle: Function

Nucleus: The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.

Mitochondria: Make energy out of food

Ribosomes: Make protein

Golgi Apparatus: Make, process and package proteins

Lysosome: Contains digestive enzymes to help break food down

Endoplasmic Reticulum: Called the "intracellular highway" because it is for transporting all sorts of items around the cell.

Vacuole: Used for storage, vacuoles usually contain water or food. (Are you are thirsty? Perhaps your vacuoles need some water!)

Plant cells also have:

Chloroplasts: Use sunlight to create food by photosynthesis

Cell Wall: For support
