Question # 4

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.

Question # 5

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.
b) Mucular tissue swhich perform contractions of stomach walls for grinding of food, mixing enxyme with food and moving food to posterior end.

Question # 6

What is organ system? Give examples.

Ans 1: In higher multicellular organisms, particulary in animals, differente organs ,performign related functions are organized together in the form of an organ system for example, digestive sytem carries out proess of digestion.

Question # 10

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.
