Question # 1

What is chlorosis?What is it cause?

Ans 1: Magnesium and Nitrogen deficiency also cause chlorosis in plants particularly in the leaves because these elements are important part of chlorophyll without them chlorophyll reduced and chlorosis occurs.

Question # 2

What is radula?

Ans 1: Garden snail feeds by using rasping organ,the radula.Leaves are held by the lips of the snail.The radula moves back and forth over the leaves and its teeth scrape the food.

Question # 3

Define microphagous feeding with example.

Ans 1: The animals which feed on large food particles or pieces are macrophagous feeders.In includes.
Tentacular feeding for example as in hydra.

Question # 5

What do you know about fluid feeders?

Ans 1: The animals which feed upon liquid or suck the fluid materials are called fluid feeders.

Question # 6

Differentiate between Nutrition and Nutrient.

Ans 1: Nutrition : Some of all process involved in the taking an utilization of elements by which growth,repair and maintenance of activities in the organisms are accomplished is called Nutrition.
Ans 2: Nutrient : The food or any other substance that supplies the body with element.necessary for the metabolism is called Nutrient

Ans 1: Sublingual Gland : it is situated below the tongue.
Submaxillary gland : It is situated behind the jaws.
Parotid gland: It is situated in the front of ears.

Question # 8

What is saprophytic nutrition?

Ans 1: Feeding on dead and decaying matter such as dead leaves in the soil or rotting tree trunk is called saprophytic nutrition and derives its nutrients from host plants.

Question # 9

Write down the effect of nitrogen and potassium deficiency on plants.

Ans 1: Nitrogen deficiency in the soil result in the stunted growth of plant and chlorosis particularly in the leaves.Magnesium deficiency also cause chlorosis in plants.

Question # 10

Define symbiotic nutrition with example.

Ans 1: It is an association between two organisms in which both the organisms get their nutrition from each other.E.g mycorrhiza ,Lichens etc.
Lichens: They are mutualistic symbiotic association between certain fungi and certain photo-autotrophs algae,Fungus protects the algae partner from stronge light and desiccation and it get food from algae,While algae prepare food for the fungi as well as for itself.
