I’m not entirely sure
Cell wall is the outer permeable covering in all pants and almost all prokaryotes ! cell wall are mainly made up of cellulose , sometime by chitin!!
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.
