non membrane bound organelles#

Question 1

Cell wall struct and func

Answer 1

made of cellulose, provides mechanical support while also being permeable. It maintains cell shape. Cell wall in Fungai is composed of chitin and cellulose, whilst in algae its formed from glycoproteins.

Question 2

ribosome

Answer 2

proteins made

Question 3

centrioles

Answer 3

Struct-Consist of two microtubules at right angles, made from tubulin and arranged to forma cylinder.
form spindle fibers

Question 4

cytoskeleton

Answer 4

A network of protein structures in the cytoplasm. It consists of;

. Microfilaments- provide support and mechanical strength that keep the cells shape stable and allow cell movement.

. Intermediate filaments- anchor the nucleus within the cytoplasm.

. Microtubules- they also provide shape and support and help substances and organelles to move through the cytoplasm.

. The cytoskeletal motor proteins, allow hydrolysis of ATP.
