Question

Which of the following statement is correct ? * 1 point Plant tissues donot divide through out their life Cell growth in plants is more uniform as compared to animals Animals have more living tissues as compared to plants There is demarcation of dividing and non dividing regions in animals

Answer 1

Explanation:

Growth is seldom random. Rather, it occurs according to a plan that eventually determines the size and shape of the individual. Growth may be restricted to special regions of the organism, such as the layers of cells that divide and increase in size near the tip of the plant shoot. Or the cells engaged in growth may be widely distributed throughout the body of the organism, as in the human embryo. In the latter case, the rates of cell division and of the increase in cell size differ in different parts. That the pattern of growth is predetermined and regular in plants and animals can be seen in the forms of adults. In some organisms, however, notably the slime molds, no regular pattern of growth occurs, and a formless cytoplasmic mass is the result.

The rate of growth of various components of an organism may have important consequences in its ability to adapt to the environment and hence may play a role in evolution. For instance, an increase in the rate of growth of fleshy parts of the fish fin would provide an opportunity for the fish to adapt more easily to terrestrial locomotory life than could a fish without this modified fin. Without disproportionate growth of the fin—ultimately resulting from random changes in the genetic material (mutations)—the evolution of limbs through natural selection might have been impossible.

Answer 2

the statement which is correct is that the growth in plants is more uniform as compared to in animals.

Option B

Explanation:

• animals overall group does not take place throughout the life. Growth only takes place in older ages during time of injury or increase in need of the body.
• However in case of plant the growth is permanent and uniform throughout the life cycle of the plant. the animal and plant living tissue depends upon the amount of living tissue and in varies from plants to plant
