In the body a specific function is performed by a specific group of cells at a definite place. This group of cells is called a ______.

In the body a specific function is performed by a specific group of cells at a definite place. This group of cells is called a tissue.

The tissue of plants whose cells are actively dividing throughout their life are called ______.

The tissue of plants whose cells are actively dividing throughout their life are called dividing tissue. This tissue is also called meristematic tissue. Hence option 4 is the right answer.

Which of the following statement is not true with respect to plant and animal tissues?

Due to different body structure plants and animals have different types of tissues. We know that plants stand upright in one place. Therefore they need support. That's why in plants supportive tissues are present in large amounts. Supportive tissues are made up of dead cells. Therefore most of the tissues of animals are made up of dead cells. Animals can move from one place to other. That's why animal require more energy than plants. That's why in animals most of the tissues are made up of living cells. Hence statement of option 1 and 2 are not true. Hence option 3 is correct answer.

Which of the following cell organelle is not present in the cells of meristematic tissue?

The cells of meristematic tissues divides life time. That's why cells of meristematic tissues do not need to store nutrients. The function of the vacuole is to store nutrients. Since cells of meristematic tissue do not store nutrients, that's why they do not have vacuole. Hence option 1 is the right answer.

In the Science experiment Natasha has to observe the cells that divide for life time. Which plant part should Natasha cut to observe the cells that divide for life time?

We know that the cells of meristematic tissue divides life time. So to observe the cells that divides for life time, Natasha should cut the plant part where the meristematic tissue is localised. Meristematic tissue is of 3 types: apical meristem, lateral meristem and intercalary meristem. Apical meristem is present in the root tip and shoot tip. Lateral meristem is present in the lateral sides roots and stem. And intercalary meristem is present in the leaf base and near the internodes of the stem. Therefore from given options the meristematic tissue is present in the roots. So to observe the cells that divides for life time, Natasha should cut the root tip of the plant.
