Biology Urdu Medium 9th Class Chapter 5(Cell Cycle)Online Short questions with Answers Preparation

Question # 1

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 # 2

Define Atom

Ans 1: Atoms are teh smallest unit of matter that maintain the property of an element.
Example: Carbon, Hydrogen and Oxygen etc.

Question # 3

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 # 4

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 # 5

Define organelles with example

Ans 1: An enormous number of biomolecules become associated in a particular way and form organelles. The orgnelles are actually sub cellular structures. e.g. mitochondira ribosomes etc.

Question # 6

What is a tissue level?

Ans 1: Introduction:
In multicellular organisms, cells make tissues. A tissue is a group of similar cells that work together to perform one or more specific functions.
Example:
In animals:
Epithelial tissue- covers body surfaces and lines cavities e.g. skin
Muscle tissue-enables movement e.g. cardiac muscle in the heart.
In Plant:
Epidermal tissue-Protects the underlying parts e.g. epidermis of leaf
Vascular tissue-Transports water and nutrients e.g. xylem and phloem.

Question # 7

Define Homeostasis and its importnace.

Ans 1: Introduction :
The organs and organ systems of the body work in coordination to maintain a stable internal environement. It is called homeostasis.Homeostasis is defined as the body's ability to maintain a stable internal environment despite the changes in the external environemnt
Example:
Examples of homeostasis include regulating the temperature, blood pressure, bllood sugar, and pH levels.

Question # 8

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 # 9

Define Molecule

Ans 1: Atom combine to form moleculs which cna have entirely different properti thant he atoms they contain.
Example:
Water, protein and nucleic acid etc.

Question # 10

Define Orgenelle

Ans 1: Molecules combine in specific ways and make the subcellular level i.g. orgenelle Each organelle is specialized to do a particular function.
Example: Mitochondria are responsible for cellular respiration and ribosomes are speciealized for protein synthesis.
