Which among the following is incorrect about tissues in a plant?

A cluster of cells that have a common origin and work together to achieve a specific function A plant tissue varies from that of an animal because they vary in their functions and characters In plant there are two types of tissues, namely, Meristematic and permanent tissues Secondary Meristematic tissues comprises of sclerenchyma, collenchymas, parenchyma and epidermis

Which among the following statements is incorrect about Meristematic tissues?

Meristematic tissues are quite small which allows large number of cell division Their cytoplasm is quite dense which means that they contain many cell organelles that help them increase their rate of respiration Their cell wall is thin which allows them to divide easily Larger vacuoles let them break easily and give mechanical support

Which among the following is not correct about primary and secondary Meristematic tissues?

Primary meristem rises at the early stage of a plant and comprises of apical and intercalary meristem Secondary meristem rises at the later stage of a plant and comprises of later meristem Apical meristem is present at tips of root and shoot and also helps in the increase of length Intercalary meristem helps in the increase of girth in plants

Which among the following is not correct about permanent tissues?

Permanent cells are formed from the meristem tissues that gradually lose their ability to divide and perform few other specific functions Process by which meristem tissues gradually change to permanent tissues is called Differentiation Permanent tissues are classified into simple and complex permanent tissues Simple permanent tissues and complex permanent tissues are classified based on their intercellular gaps

Which among the following is incorrect about Sclerenchyma?

These are the living tissues responsible for stiffness in plants The husk of a coconut is made of Sclerenchymatous tissue They are of two kinds, namely, sclereids and fibers Simple pits are present in thickened cell walls of sclerenchyma

Which of the following is not a feature of spring wood?

Color of the wood is light. Density is less. Cambium is active. Lesser number of xylary elements.

Secondary meristem develops from

Apical meristem Permanent tissue Secondary tissue Vascular combium

Cambium is considered to be a lateral meristem because it

Gives rise to lateral branches Increase the girth of the plant Increase both length and girth of plant Increase the length of the plant.
