A tissue is a group of cells which are
1 similar in origin, but dissimilar in form and function.
2 dissimilar in origin, form and function.
3 dissimilar in origin, but similar in form and function.
4 similar in origin, form and function.
Explanation:
(d) A group of structurally similar or dissimilar cells that perform a common function and have a common origin is called a tissue. A plant is made up of different kinds of tissues.

Which meristem helps in increasing girth?
1 Lateral meristem
2 Intercalary meristem
3 Primary meristem
4 Apical meristem
Explanation:

Which of following helps bamboo and grasses to elongate?
1 Apical meristems
2 Lateral meristems
3 Secondary meristems
4 Intercalary meristems
Explanation:
(d) Intercalary meristem develops between regions of mature or permanent tissue (at the base of the grass leaf). The cells of this tissue possess the ability to divide and produce new cells, as do apical and lateral meristems. Intercalary meristem helps the bamboo and grasses to elongate.

Cells of permanent tissues are specialized
1 functionally.
2 only structurally.
3 both structurally and functionally.
4 for mitosis.
Explanation:
(c) Divisions of cells in both primary as well as secondary meristems, the newly formed cells become structurally and functionally specialized and lose the ability to divide. Such cells are termed as permanent or mature cells and constitute the permanent tissues.
