Answer 1

Answer:

Respiration in plants

_________________

1. plants only respire

2.Animals breath air for cellular respiration.

Respiration in animals

__________________

1.Plant obtain oxygen directly from the air through stomata.

2.Animals inhale oxygen from nose or gills into respiratory organs.

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.

Aerobic fermentation is a metabolic process by which cells metabolize sugars via fermentation in the presence of oxygen and occurs through the repression of normal respiratory metabolism (also referred to as the crabtree effect in yeast). This phenomenon is rare and observed mostly in the yeast.

lenticels

In hard and woody stems, respiration or the exchange of gases takes place through lenticels. They are the small pores, scattered all over the bark and are found in all trees.

Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.

Insects have no lungs. Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. ... Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.
