column a - answer|column b - cell organelle descriptions
(a) site of protein synthesis
(b) synthesizes steroid hormones
(c) forms the mitotic spindle and the base of cilia
(d) site of ribosome synthesis
(e) energy - generating powerhouse of the cell
(f) control center of the cell
(g) contains the cell contents and separates them from the surrounding environment
(h) sac of digestive enzymes
(i) assembles and packages materials in vesicles to be secreted from the cell
(j) membrane network studded with ribosomes
true or false questions: (4 marks)

Explanation:

(a) Ribosomes are the sites of protein synthesis. (b) Smooth endoplasmic reticulum synthesizes steroid hormones. (c) Centrioles form the mitotic spindle and the base of cilia. (d) Nucleolus is the site of ribosome synthesis. (e) Mitochondria are the energy - generating powerhouses of the cell. (f) Nucleus is the control center of the cell. (g) Cell membrane contains the cell contents and separates them from the surrounding environment. (h) Lysosomes are sacs of digestive enzymes. (i) Golgi apparatus assembles and packages materials in vesicles to be secreted from the cell. (j) Rough endoplasmic reticulum is a membrane network studded with ribosomes.
