Question # 4

Difference between Epidermal and mesophyll tissue.

Ans 1: Epidermal Tissue:
The outermost layer of leaf is made of epidermal tissue
The upper epidermis is usually covered by waxy cuticle which reduce water loss and provides protection
The lower epidermis oftern contains guard cels.Two guard cells enclose a Stoma whcih are tiny pores that regulate gas exchagne and water vapour loss.
Ans 2: Mesphyll tissue:
This tissue lies between the upper and lower epidermis
It consists of cells rich in chloroplasts
It is the site of photosynthesis it is divided into two distinct regions palisade mesophyll and spongy mesophyll

Question # 5

What is tissue level? Give one example.

Ans 1: A group of similar or differente types of cells peforming same function e.g. xylem and phloem in plants, ar ecomposed of different cells while nerous tissues are composed of same type of cells.

Question # 6

Difference between Root system and Shoot system

Ans 1: Root System: The root system consists of two main structures includig the root cap and the primary root
The root system anchors the plant and absorbs water and nutrients.
Ans 2: Shoot system:
The shoot system consists of two portions. the vegetative and reproductive parts of the plant.
The shoot system components stems, leaves and reproductive structures like flowers work together to enable processes like photosynthesis and reproduction.

Question # 7

Define Cell

Ans 1: When organelles assemble and interract with each other, they make cell-the smallest unti with characteristics of life. They can carry out life activities and can also reproduce.
Example: Unicellular organismsm are made of only one cell while multicellular organisms are made of many cells.

Question # 8

Palisade and spongy mesophyll

Ans 1: Palisade Mesophyll:
It is located just beneath the upper epidermis
It consists oftighty packed elongated cells.
Their cells are rich with chloroplasts and has major role in photosynthesis
Ans 2: Spongy MesophyII:
It is presnet below the palisade mesophyII
It is composed of loosely arranged cells with air spaces between them.
These air spaces facukutate tge duffysuib if gases throughout the leaf.

Question # 9

How do the smooth muscles contribute to the stomach's functin.

Ans 1: The smooth muscle in the stomach is primarity responsible for.
1. Churnign and mixing food with stomach acid
ii. Producing chyme by contracting and relexing in a coordinated manner which helps with digestion and peropels the partially digested food into the small intestine through a process called peristalsis.
iii. It facilitates the movement and mechanical breakdown of food within the stomach.

Question # 10

How different tissues form stomach.

Ans 1: i. Stomcah is an orga specialized for the disgestion of proteins and storing food
ii. Stomach has:
a) Epithelial tissues which secrete the gastric juice.
