Life Processes Worksheet-23

 

State whether the following statement is True or False. If False then state the correct one:

  1. Living and non living things can survive independently in the ecosystem.

 

  1. Living things shows functions like metabolism, movement, growth and reproduction in a self imposed manner for their survival on earth.

 

  1. Non- living things are those which cannot grow on its own.

 

  1. Growth is associated with cell division and enlargement.

 

  1. Catabolism is constructive process while anabolism is destructive process.

 

  1. Photosynthesis is an example of anabolic reaction.

 

  1. Catabolic reactions release the energy which is stored in the form of ADP.

 

  1. The energy released due to breakdown of ATP is released out in surrounding in different forms.

 

  1. Growth is defined as increase in size, number or mass of the cell.

 

  1. Growth supports the process of reproduction only.

 

  1. Oxygen evolved during photosynthesis is evolved due to splitting of carbon dioxide molecule.

 

  1. Photosynthesis is anabolic process.

 

  1. In a typical leaf photosynthesis mainly occurs in epidermis.

 

  1. Light energy is transformed into chemical energy during dark phase.

 

  1. Hill reaction occurs in grana of chloroplast.

 

  1. Reduction of carbon dioxide to glucose during photosynthesis occurs in stroma of chloroplast.

 

  1. Two oxygen molecules are evolved by the splitting of four water molecules.

 

  1. Glucose is the end product of photosynthesis.

 

  1. The storage form of glucose is lignin in plants.

 

  1. The electrons released due to photolysis of water are used to reduce NADP.

 

  1. The energy in the form of electrons is used to add a molecule of phosphate to ADP.

 

  1. The space enclosed by double membrane envelope in chloroplast is filled with matrix known as granum.

 

  1. Water is the only source of hydrogen ions which plants can use for photosynthesis.

 

  1. Oxygen produced in photosynthesis is used in respiration this is known as photorespiration. (True)

 

  1. The mode pf nutrition by which plants can synthesize their own food is heterotrophic nutrition.
