Question

1 2 points possible multiple choice
which of the following structures are part of a cells cytoskeleton and provide support to the cell shape?
ribosomes
microtubules
lysosomes
flagella
(response not displayed)
2 2 points possible multiple choice
a group of cells that are similar in structure and work together to perform a common function are referred to as a(n)
organ.
organism.

Explanation:

1. For question 1: Ribosomes are responsible for protein synthesis, lysosomes handle intracellular digestion, flagella are for cell movement. Microtubules are a core component of the cytoskeleton, providing structural support to maintain cell shape.
2. For question 2 (note: the full option set is cut off, but based on standard biological definitions): An organ is a structure made of multiple tissue types, an organism is a complete, independent living entity. A tissue is a group of similar cells working together to carry out a shared function, which matches the description.

Answer:

1. microtubules
2. tissue (standard correct answer for the given definition, as the full option set is incomplete)
