After seeing the attached picture represented above, it has become more clear and I think that the best explanation for why the onion cells do not burst, while red blood cells often do, is that the red blood cells have only a cell membrane, which does not protect them from bursting. The main point which makes difference between two parts of picture is that one of the cells has protective membrane.
Hope you will find it helpful.
Regards.

The onion cells are plant cells, and plant cells have cell membrane and cell wall both. The cell wall is composed of the cellulose, and it provides rigidity to the cell and helps the cell to maintain its shape. That is why when an onion cell is put in distilled water, it did not burst.

However, the red blood cells do not have cell wall. They only have cell membrane, which cannot provide rigidity to the cell, and therefore, it bursts when put in distilled water.

Hence, the correct answer is option (1) - 'the red blood cells only have cell membrane which does not protect them from bursting'.

Answer:

Explanation:

Golgi apparatus, a membrane-bound organelle with cisternae, delivers proteins and lipids from the endoplasmic reticulum to where they are needed- such as for secretion outside the cell. Fused vesicles with proteins/lipids that pinch off from the trans end of the ER fuse with the cis end of the Golgi apparatus delivering the ‘cargo’. The proteins/lipids are then given post-translation modified and ‘marked’ for different deliveries. At the trans end of the Golgi apparatus, the vesicles pinch-off with the modified proteins and transported to their destination.

1.) Compare the roles of oxygen and carbon dioxide in autotrophs and heterotrophs. Which organism is an oxygen consumer and carb

wariber [46]

Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

I hope I helped!
