The telescope is cylindrical.
Its primary mirror is concave.
The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
Reflecting Telescopes -uses a single or combination of curved mirrors to bring light to a focus and make an image.
Isaac Newton invented the reflecting telescope.
Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.
reflecting telescope gathers light from mirror
Convex
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
a. concave mirror b. a convex lens c. a plane mirror or d. all the above.

Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.
cancave plasmolysis ar always irreversible and convex ar usually reversible.
