Question

what are the main functions of each of the following cell components? a) plasma membrane b) chloroplast c) nucleus d) cell e) ribosomes f) peroxisomes? biology

Answer 1

Plasma membrane- it is the outermost membrane of a cell which seperates cell from its external environment. It allows the entry and exit of specific molecules thats why it is also known as semi permeable membrane. Chloroplast- choroplast is only present in plant cells and its green colour is given by chlorophyll. It helps the plant for making food in the process of photosyntesis. Nucleus- it contains chromosomes which contains genes for the inheritance of characters from parents to offspring. Cell- cell is the basic sructural unit of a living cell. It is capable of doing all tha tasks like respiration, excretion etc. Ribosomes- ribosomes are present on the surface of rer. It is the actual site of syntesis of proteins. It syntesis proteins.

Answer 2

Peroxisomes break very long chains of fatty acid.
