Answer:
Mitochondria:-
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
collenchyma:-
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
synergids:-
The synergid cell wall forming a thick structure at the micropylar end and it is called filiform apparatus. Its function is to guide the entry of pollen tube and release of sperm cells.
micropyle:-
The micropyle helps to absorb water at the time of germination of the seed. It is through this micropyle that the root emerges at the time of germination of the seed. The opening of the micropyle allows the pollen to enter the ovule for fertilization.
Vocal cords:-
the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.
