Bacteria are ___________ (1) microscopic organisms. They can be harmful as well as _________ (2) in many ways. A bacterial cell resembles plant cell in having __________ (3). Bacterial cells do not have true ___________ (4) and lack membrane-bound __________ (5). The rod shaped bacteria are called ___________ (6).

Colourless, unicellular, cell wall bound, spherical or rod-shaped microorganism and lacking organised nucleus is called

Assertion : The cells that have membrane bound organelles are called eukaryotic. Reason : The cells that lack membrane bound organelles are called prokaryotic.

Which of the following is correct: (a) Cells of all living organisms have a nucleus. (b) Both animal and plant cells have a well defined cell wall. (c) In prokaryotes, there are no membrane bound organelles. (d) Cells are formed de novo from abiotic materials.

How many of the following organisms possess membrane bound cell organelles and autotrophic mode of nutrition? (Hibiscus, Lily, bacteria, Amoeba) (a) 0 (b) 4 (c) 2 (d) 3

What is true for Archaebacteria? (a) They all are halophiles (b) They differ from eubacteria in having different cell wall (c) They have membrane bound cell organelles (d) They lack introns in their genetic material

Protists are 1. _____________ (prokaryotic/eukaryotic) containing a well-defined nucleus in their cells. While 2. _________________ (Euglena/Amoeba) moves with the help of pseudopodia, Paramoecium has hair-like structures all over its body called 3. __________________ (cilia/flagella). Entamoeba is a 4. __________ (saprophytic/parasitic) protist causing amoebiasis. 5. __________ (Chlamydomonas/Euglena) is a unique protist, which is both autotrophic and heterotrophic.

As per Whittaker's classification, an organism possessing eukaryotic cell structure, multicellular organisation with a cell wall and nuclear membrane, showing heterotrophic nutrition can be placed under the kingdom

Besides the ————————, the eukaryotic cells have other membrane bound distinct structures called organelles like the endoplasmic reticulum (ER), the golgi complex, lysosomes, mitochondria, microbodies and vacuoles.

DNA cannot pass through a cell membrane as 1) it is too big to cross the memebrane 2) it is a hydrophilic molecule 3) membrane does not have specific proteins to facilitate the transport 4) none of these

Find out the incorrect statements : (1) Blue-green alga is a prokaryotic cell. (2)WBC is amoeboid in shape. (3) Mycoplasma is the largest cell. (4) Microbodies are cell organelles. (5) Prokaryotes do not exhibit a wide variety of shapes.
