Study of plant population frequency by quadrat method
 1) The plant population frequency can be defined as: The total number of individuals of the species in any unit area at given time. Total number species in all the sampling quadrat. The degree of uniformity of the occurrence of individuals of a species within a plant community. A sample plot of a specific size used for the study of population.

 2) What is a quadrat? Number of sampling units in which species occurs. A large plot divided into 4 small plots. A sample plot of a specific size used for the study of population. The number of individuals of the species in any unit area at given time.

 3) Which among the following factors are effecting the variation in plant distribution? Soil conditions. Vegetative propagation. Predation by insects. All of them.

 4) If a species is present in all sampling quadrats, then its frequency will be ____. 100% 0 50% 1

 5) What does it mean if the frequency of a plant is high? The species is absent. The number of individuals of the species is very small. The species is rarely distributed. The species is widely distributed.

 6) An ecologist divided a plot into 8 quadrats and studied the frequency of a particular species. He found the species occurs in 3 quadrats. According to his measurements, what is the frequency of the specific species? 62.5% 80% 72% 37.5%

 7) How do you calculate the plant population frequency? %Frequency=(Total number of sampling units employed for the study)/(Number of sampling units in which the species occurs)*100 %Frequency=(Total number of sampling units employed for the study)/(Total no.of individuals of the species in all the sampling unit)*100 %Frequency=(Total no.of individuals of the species in all the sampling unit)/(Total number of sampling units employed for the study)*100 %Frequency=(Number of sampling units in which the species occurs)/(Total number of sampling units employed for the study)*100

 8) Calculate the population frequency of sunflower plant from the below image. 71.42 50.07 70 100
