Q.6 list in tabular form differences between all three types of simple permanent
tissue.
Q.7 what is stomata? give its functions.
Q.8 give three points of differences between xylem and phloem.
Q.9 How many types of elements together make up the xylem tissue? name them.
Q.10 list any four features of meristematic tissue.

Answer 1

Q6. Permanent tissues are made of meristematic cells, that has definite form and shape and have lost the power to divide and differentiate and are of three types- simple, complex and special. The simple tissues are parenchyma, sclerenchyma and collenchyma. Chlorenchyma is a parenchyma, having chloroplast.

Q7. So the numerous Force Under the surface of the leaf are called stomata and their functions are transportation that is taking water to every part of the tree and the exchange of gases.So let us write down the numerous pores under the surface of the leaf, and the second is the exchange of case.

Q8. Xylem Tissues

Xylem is one of the important tissues of the vascular system of plants. The main activity of this tissue is to transport minerals and water from roots and carry them to other parts of the plants. It has two separate chambers, tracheids and vessels for transporting minerals and water. The term xylem is derived from the Greek word – (xylon), meaning wood.

Phloem Tissues

Phloem is also important as the xylem tissues for the vascular system of plants. The main activity of this tissue is to transport nutrients and food from leaves to other growing parts of plants. The term phloem is derived from the Greek word – (phloios), meaning bark.

Q9. Xylem tissue is made up of four different types of cells- tracheids, vessels, xylem parenchyma and xylem fibres.

Q10. (i) Cells divide repeatedly.

(ii) Cell walls are thin.

(iii) Vacuoles are not found.

(iv) Metabolically very active.

(v) They have dense cytoplasm.

Answer 2

Answer:

hey mate here is ur answer

☮️6. Simple Permanent Tissue Vs. Complex Permanent Tissue In Tabular Form

BASIS OF COMPARISON :- SIMPLE PERMANENT TISSUE/ COMPLEX PERMANENT TISSUE

Examples:- Examples of simple complex tissue include: Sclerenchyma parenchyma collenhymas / Examples of complex permanent tissue include: Xylem

7. Stomata are tiny openings or pores in plant tissue that allow for gas exchange. ... Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis

9.four different types

Xylem tissue is made up of four different types of cells- tracheids, vessels, xylem parenchyma and xylem fibres
