Answer:

<em>Plant cell wall</em>

Explanation:

Microtubules: These are hollow cylinders constituted by a protein called tubulin. They are important components of the cytoskeleton providing support and transport mediums to the cell.

Microfilaments: one of the fundamental components of the cytoskeleton, they are composed of filaments of the actin protein. Microfilaments are abundant in the region adjacent to the membrane, where they associate with other proteins to compose the cytoskeleton.

Cell wall: composed of polysaccharides and glycoproteins organized in a tridimensional <u>matrix</u>. The most important component is cellulose, composed of repeated glucose units joined between them. Each cellulose molecule contains about 500 glucose units.

Intermediate filaments: Insoluble, cytosolic, fibrous proteins that are present in every eukaryotic cell. They compose the cytoskeleton that supports the cellular structure and are involved in different metabolic and physiological processes. They participate in internal organelles organization.

Nuclear lamina: intercrossed net of intermediate filaments composed by lamins proteins. It is located in the nucleoplasm periphery in contact with the inner face of the nuclear cover.

Why are groups of small cells better then one large cell at moving material in and out
Andrej [43]
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also for efficient for these smaller and miniscule cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy.

Free_Kalibri [48]

Answer:

The correct answer will be option-E.

Explanation:

Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.

These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.

Thus, option-E is the correct answer.
