Q.4. While walking through garden, Kapil plucked
the tips of some flowering plants. Gardner saw
him doing this and persuaded him not to do so
as it is not good for plant growth.
(i) What happens to the plants if their tips are
removed ?
(ii) What are meristems?
(iii) How meristems are classified ?
(iv) What value was displayed by the gardner ?
Answers
Answer:
1) If the tips of plants are removed then that plant will not grow becoz the apical meristem which helps in primary growth are removed.
2) Meristems are the sites of production of non-specialised cells in plants and are the only sites for cell division in a plant.
3) Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).
4) The value displaced by the gardner is that he has the responsibility of keeping the plants safe and he did so by telling Anil, he took care of the plants.Also he is shown particular towards the environment and he takes care accordingly He taught Anil proper advice to not to do.

Answer:
(i) In flowering plant, apical meristems are present at tips of branches of the plants and their removal will stop the further longitudinal growth of the plants.
(ii) Meristems are tissues present in plants and are composed of rapidly dividing cells with dense cytoplasm.
(iii) Meristems are growth tissues and are classified on the basis of their position in the plant body. They are of three main types: apical meristem (at growing ends of stems and roots), lateral meristems (i.e., cambium for secondary growth ) and intercalary meristem ( at base of leaves or at internodes of grasses).
