Answer: Option D. -> Cyanobacteria and Eubacteria
:
D
Cyanobacteria and Eubacteria are prokaryotes and they have nuclear matter without an envelope.

Answer: Option C. -> Small cells have a large surface area per volume ratio
:
C
Small cells have a larger surface area per volume ratio when compared to large cells. hence smaller cells can absorb more number molecules than larger cells.

Answer: Option C. -> Viruses
:
C
Viruses lack the typical structure of a cell and donot perform any functions of a cell hence cell theory is not applicable to viruses.

Answer: Option A. -> amino acids and glucose
:
A
Na+ ions facilitates the absorption of glucose and amino acids. Secondary active transport is one of the two main types –
cotransport (e.g. glucose and some amino acids along with inward pushing of Na+) and counter transport (Ca2+ and H+import outwardly as excess Na+ passes inwardly).

Answer: Option B. -> ribosomes on the surface of ER
:
B
Endoplasmic Reticulum consists of complex membranous systems in the cytoplasm of eukaryotic cells. The ER having ribosomes on the surface is known as RER while the ER without ribosomes is called the smooth ER.

Question 6. Read the following statements and identify the correct option given.
I. In prokaryotic cell. The nuclear membrane, chloroplast, mitochondria, microtubules and different kinds of pili are absent.
II. In eukaryotic cell, the nuclear membrane, chloroplast, mitochondria and pili are present.
III. In prokaryotic cell, the ribosome is of 70 S type and in mitochondria of eukaryotic animal cell, the ribosome is of 80 S type.

III. In prokaryotic cell, the ribosome is of 70 S type and in mitochondria of eukaryotic animal cell, the ribosome is of 80 S type.
Answer: Option D. -> I, II and III are correct
:
D
Prokaryotes are generally smaller and differ from eukaryotic cells in terms of structural elements and genetic processes e.g., bacteria, blue-green algae, mycoplasma, etc.
Unlike eukaryotes, prokaryotes lack a true nucleus, a nucleus membrane and the membrane bound organelles (mitochondria, chloroplast, Golgi bodies, ER)
Ribosomes are 70 S type in prokaryotes, while it is 80 S in eukaryotes although 70 S type inprokaryotes, while it is 80 S in eukaryotes although 70 S type of ribosomes are found inmitochondria and chloroplast of eukaryotic cell.

Answer: Option C. -> Lysosome
:
C
Nucleus, mitochondria, and chloroplast are double membrane bound organelles.
:
C

Answer: Option A. -> Mitochondria
:
A
:
A
- Theendomembrane system(endo- = “within”) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins
- Endomembrane system includes ER,Golgi complex, lysosomes, and vacuoles.
Answer: Option C. -> micro tubular organisation and type of movement.
:
C
Flagella of prokaryotic andeukaryotic species differ in micro tubularorganisation and type of movement. In eukaryotes, the arrangement is (9 + 2) and specialized while inprokaryotes arrangement is simple.
