Assertion: Glyoxisome, sphaerosome, lysosome are surrounded by single membrane. Reason: Quantasome present in chloroplast.

Assertion: Eukaryotes contain membrane bound cell organelles and linear chromosome present in nucleus. Reason: In prokaryotes nucleus is present.

Assertion: Mitochondria & Chloroplast are connected with similar RNA sequence. Reason: They show prokaryotic organisation

Assertion: DNA is found in mitochondria and chloroplast is called prochromosome. Reason: They are similar to prokaryotic chromosome.

Bacteria cannot survive in a highly salted pickle because

Assertion (A) A cell membrane shows fluid behaviour. Reason (R) A membrane is a mosaic or composite of diverse lipids and proteins.

If a biochemical analysis of mitochondria has to done, the best procedure would be

Which one of the following structure is an organelle within an organelle?

Assertion (A) A cell membrane shows fluid behavior. Reason (R) A membrane is a mosaic or composite of diverse lipids and proteins.

Osmosis is a type of

Assertion Lysosomes are organelle in eukaryotic cells that contains digestive enzymes to digest macromolecules. Reason Lysosomes are also called phagolysosomes or heterophagosomes or digestive vacuoles.

Assertion Eukaryotic are more complex than prokaryotes genetically.

Which of the following organelles contain DNA?(i) Mitochondria (ii) Chloroplasts (iii) Golgi bodies (iv) Ribosomes

Assertion: Mitochondria and chloroplasts have their own genome. Reason: Endoplasmic reticulum and Golgi body are the cell organelles which have their own DNA.

Cell theory was proposed by

In active transport, carrier proteins are used, which use energy in the form of ATP, to

What do A, B, C, and D represent in the following figure?

What is correct about the movement of substance across the membrane in facilitated diffusion?

What are Singer and Nicolson known for?

Assertion: Shrinkage of the protoplast of a cell occurs under the influence of hypertonic solution. Reason: Hypertonic solution causes plasmolysis.

Assertion: Nucleus is the controlling centre of a cell. Reason: Pores in the nuclear envelope regulate the flow of materials in and out of the nucleus.

How many genome types are present in a typical green plant cell?

"Omnis-cellula-e-cellula" was given by

Which of the following is responsible for the mechanical support, protein synthesis and enzyme transport?

Genes present in the cytoplasm of eukaryotic cells are found in

In prokaryotes, chromatophores are

What is common between chloroplasts, chromoplasts and leucoplasts?

Assertion: Gram-negative bacteria do not retain the stain when washed with alcohol. Reason: The outer face of the outer membrane of Gram-negative bacteria contains lipopolysaccharides, a part of which is integrated into the membrane lipids.

Assertion : Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements. Reason : There are three principal types of protein filaments - microfilaments, microtubules and intermediate filaments, which constitute the cytoskeleton.

Many cells function properly and divide mitotically even though they do not have

Three of the following statements regarding cell organelles are correct while one is wrong. Which one is wrong?

Assertion : Mitochondria and chloroplasts are semi-autonomous organelles. Reason : They are formed by division of pre-existing organelles as well as contain DNA but lack protein synthesizing machinery.

DNA is present in

Plasmodesmata connections help in:

Assertion : A cell membrane shows fluid behaviour. Reason : A membrane is a mosaic or composite of diverse lipids and proteins.

Which of the following is related to glycosylation of protein?

Assertion : The number of cells in a multicellular organism is inversely proportional to the size of body. Reason : All the cells in the biological world are of same size.

Assertion : It is important that the organisms should have cell. Reason : A cell keeps its chemical composition steady within its boundary.
