Direction: Study the given diagram of bacterial cell and answer the following questions.

Q. Nearly bacteria are motile due to the presence of ___________.

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 1

Nearly half of the bacteria are motile due to the presence of flagella. These are long, thin, helical appendages.

Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 2

Direction: Study the given diagram of bacterial cell and answer the following questions.

Q. The nuclear region in the diagram contains

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 2
  • Chromosome beasis genes present in nuclear region.

  • Genes are contained in chromosomes, which are in the cell nucleus.

  • A chromosome contains hundreds to thousands of genes.

  • Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.

  • A trait is any gene-determined characteristic and is often determined by more than one gene.

Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 3

Direction: Study the given diagram of bacterial cell and answer the following questions.

Q. The parts (1), (2) and (3) are

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 3

It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.

The outer structure (1) is the cell wall.

Then the genetic data(2) is nucleoid.

The second layer(3) is the plasma membrane.

Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 4

Direction: Study the given diagram of bacterial cell and answer the following questions.

Q. Bacteria has no nucleus so, bacteria is

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 4
Prokaryotes do not have nucleus or undefined and undeveloped nucleus.

A prokaryotic cell does not have a defined nucleus; the nuclear material in a prokaryote is known as a nucleoid. DNA present in the nucleoids of prokaryotes is of circular, double stranded type which is tightly coiled. Hence, due to the circular structure and tight coiling, the DNA in prokaryotes is not scattered throughout the cell, even though the cell has no defines nucleus.

Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 5

Direction: Study the diagram of a plan cell and answer the following Questions-

Q. Which cell organelle is involved in synthesis of vacuoles ?

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 5
Golgi help in the synthesis of vacuoles containing cellular secretion, digestive enzymes, protein etc.
Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 6

Direction: Study the diagram of a plan cell and answer the following Questions-

Q. The special structures in plant cell known as Kitchen of the Cell

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 6
Plants contains Plastids and Chloroplast is a type of Plastid where photosynthesis take place.
Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 7

Direction: Study the diagram of a plan cell and answer the following Questions-

Q. Plant Cell wall is made up of

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 7
Plant cell wall is made up of cellulose, hemicellulose and pectin. Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.
Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 8

Direction: Study the diagram of a plan cell and answer the following Questions-

Q. Plant Cell have large _______ than animal cells.

Detailed Solution for Test: The Fundamental Unit of Life- Case Based Type Questions- 1 - Question 8
In a plant cell,vacuoles plays very important role as they store toxic metabolic byproducts or and product and provide turgidity and provide turgidity and rigidity to plant cell.
