C)What is the diversity in the size of a cell?

D)name the cell have branched structure?

E)What are the basic components of a cell?

F)Is cell wall living or dead?

G)Is plasma membrane living or dead?

Answer 1

(A) Mycoplasma gallicepticum, a parasiticbacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction. The cell in the work is known as mycoplasma. Its diameter is 0.0001 mm.

(B)Biologists used the world's largestsingle-celled organism, an aquaticalga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.

(C)Cell Diversity

Size

-Cell size range: 1 micrometer - 200 micrometers.
-Advantages of being small: large surface to volume ratio, so things can be moved in and out efficiently. Also, diffusion time to center of cell is low
-Advantages of being large: Can compartmentalize functions.
-Advantages of being long: Single nucleus can maintain control over large distance. Can conduct fluids or signals unobstructed. Differentiation and specialization -Shape, structure and biochemistry often reflect function
-Examples: red blood cell, nerve cells, rod cell, phloem and xylem cells of plants
-Some cells are dead at maturity (e.g. xylem cells)
-Red blood cells lose nucleus and important functions

(D)Neurons or Nerve cells

(E)Cytoplasm The fluid between the nucleus and surface membrane

Plasma Membrane Surrounds the cell and is made up of proteins and lipids (known as the phosphobilipid layer)

Cytoskeleton Contained within the cytoplasm; a supportive framework of protein filaments, tubules, and organelles

Organelles Structures that perform metabolic tasks within the cell

Cytosol Also known as the Intracellular Fluid (ICF). The cytoskeleton and organelles are embedded in the ICF (a clear gel)

Extracellular Fluid (ECF) All body fluids not contained with in the cell (also called the tissue fluid) What are some examples of ECFs? Blood Plasma, Lymph, and Cerebral Spinal Fluid (CSF)

(F) . The cell wall is a protective layer; constitutes of complex polysaccharides chain around a living cell. Hence, it’s a part of living cell but can not be consider as living thing alone as it lacks the basic properties of a living organism such as reproduction or movement.
(G) Plasma membrane is a living thing elastic selectively permeable membrane
