Difference between the polysaccharide and chitin

Posted by Monika Lakra 6 years, 6 months ago

CBSE > Class 11 > Biology

2 answers

Amira Verma 6 years, 6 months ago

Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose. In the biosphere, over 1 billion tons of chitin are synthesized each year by organisms. This extremely versatile molecule can form solid structures on its own as in insect wings, or can combine with other components like calcium carbonate to make even stronger substances like the shell of a clam.

3 answers

Yogita Ingle 6 years, 6 months ago

Mesosomes are extensions of plasma membrane into the cell in the form of vesicles, tubules and lamellae.
These are of two types : Septal mesosome and Lateral mesosome.
(a) Septal mesosome may be involved in cell wall formation, chromosome replication and distribution of chromosomes to daughter cells, secretory processes and increase in plasma membrane surface area and enzymatic content.
(b) Lateral mesosome contains respiratory enzymes often called chondroid.

What is plasmalemna in protozoa

Posted by Sriee Amruthaa 6 years, 6 months ago

CBSE > Class 11 > Biology

1 answers

Meghna Thapar 5 years, 4 months ago

Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds. The plasma membrane is a barrier between the cell cytoplasm and the outside liquid environment. Some substances, such as oxygen, readily pass through the membrane by diffusion (passive transport), while others must be transported across at the expense of energy (active transport).

Posted by . . 6 years, 6 months ago

CBSE > Class 11 > Biology

1 answers

Meghna Thapar 5 years, 4 months ago

All living phenomena are due to underlying interactions. Properties of tissues are not present in the constituent cells. Similarly, properties of cellular organelles are not present in the molecular constituents of the organelle but arise as a result of interactions among the molecular components comprising the organelle. These interactions result in emergent properties at a higher level of organization. This phenomenon is true in the hierarchy of organisational complexity at all levels.

Explain the two different ways of biodiversity conservation

Posted by Aliya Joyson 6 years, 6 months ago

CBSE > Class 11 > Biology

1 answers

Sia ? 6 years, 6 months ago

There are two basic approaches for the conservation of biodiversity

Ex situ conservation (off-site conservation)
In situ conservation (on-site conservation)

In situ conservation, It is the conservation and protection of biodiversity in its natural habitat.

It helps in recovering population in the surroundings where they have developed their distinctive features.
Example National parks, biosphere reserves, wildlife sanctuaries.

Ex situ conservation It is the conservation of selected rare plants and animals in places outside their natural habitat

It helps in recovering population or preventing their extinction under conditions that closely resemble their natural habitats.
Example Botanical gardens, zoological parks, wildlife safari parks, gene banks, etc.
