1.The simplest of all bryophytes are:
(A) Mosses
(B) Hornworts
(C) Liverworts
(D) Whish ferns
2. All “flatworms” belong to phylum:
(A) Annelida
(B) Platyhelminthes
(C) Arthropoda
(D) Nematoda
3. The first action spectrum was obtained by:
(A) T.W. Engelmann
(B) Van Neil
(C) Melvin Calvin
(D) Ernst Haeckel
Feedback: The first action spectrum was made by T. W. Engelmann, who split light into its components by the prism and then illuminated Cladophora placed in a suspension of aerobic bacteria. He found that bacteria accumulated in the region of blue and red light of the split spectrum.
4. The dark reaction for photosynthesis occurs in:
(A) Cytoplasm
(B) Chloroplast
(C) Stroma
(D) Grana
Feedback:The dark reaction of photosynthesis takes place in the stroma of the chloroplast. The enzymes of stroma which are present outside the grana lamellae do not require light but require ATP and NADPH2 produced in the light reaction. It is also known as light independent reaction. Note that the dark reaction takes place in the stroma (aqueous fluid surrounding the stacks of thylakoids) and the cytoplasm
5. Carbohydrate digesting enzymes are called:
(A) Ligase
(B) Amylase
(C) Protease
(D) Lipase
Also Read: MCQs On Vitamins
Feedback: Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you’re eating.
6.Which type of cells in the human stomach secrete Gastrin:
(A) Mucous Cells
(B) G-cells
(C) Zymogen cells
(D) Endocrine cells
Feedback: G-cells are neuroendocrine cells responsible for the synthesis and secretion of gastrin. They are primarily found in the pyloric antrum but can also be found in the duodenum and the pancreas. They secrete gastrin when stimulated directly by vagal efferent neurons as well as GRP neurons.
7.Breakdown of alveoli of lungs is called:
(A) Asthma
(B) Emphysema
(C) Tuberculosis
(D) Lungs cancer
Also Read: MCQs On Respiratory System
Feedback: In emphysema, the inner walls of the lungs’ air sacs (alveoli) are damaged, causing them to eventually rupture. This creates one larger air space instead of many small ones and reduces the surface area available for gas exchange. Emphysema is a lung condition that causes shortness of breath.
8. Which one of the following is not a sub-phylum of Chordata?
(A) Urochordata
(B) Hemichordata
(C) Cephalochordata
(D) Verteberata
Feedback: The prevailing view holds that the phylum Chordata consists of three subphyla: Urochordata (Tunicata), Cephalochordata and Vertebrata
9.Poisonous mushrooms are called:
(A) Truffles
(B) Morels
(C) Toad Stools
(D) Agaricus
Feedback: Agaricus is a genus of mushrooms containing both edible and poisonous species, with possibly over 300 members worldwide. The genus includes the common mushroom and the field mushroom, the dominant cultivated mushrooms of the West.
10.The outer most boundary of a plant cell is:
(A) Cell membrane
(B) Cell wall
(C) Pellicle
(D) Capsule
