Question

give one function of each 1- stomata 2- contractile proteins in muscles 3- cardiac muscle.

Answer 1

Answer:

1. Stomata:- stomata is organelle found in kindom plant cell it works as converting or trap sun light (Radiation) and convert in chemical energy . And also take part in various metabolic activity.

2. Contractile protein in M/s :- Actin and mayosin are two importent Contractile protein in M/s . Various Function.

Cardiac M/s:- mesodermeally derived act as pump , Which pump blood through in our body.

Answer 2

Answer

» Stomata :

$\bigstar$ Stomata are very small opening found in the epidermis of green aerial parts of the plant in leaves.

$\bigstar$ They regulate the process of gaseous exchange and transportation.

$\bigstar$ Two cells which guards the opening and closing of the stomatal pore is called guard cells. They are kidney shaped.

» Contractile proteins in muscles :

$\bigstar$ Muscles contains a long thread like contractile proteinaceous fibrils called myofibrils.

$\bigstar$ They are capable of exhibiting contractions or relaxation.

$\bigstar$ In cytoplasm large amount myofibrils are tightly packed.

» Cardiac muscles :

$\bigstar$ Cardiac muscles are only present in the heart. They occur in the walls of heart.

$\bigstar$ Cardiac muscles contract and relax rapidly and rhythmically throughout the life.

$\bigstar$ The contraction and relaxation help to pump and circulate blood to various parts of body.
