Cell Biology and Structure

Microsomes are vesicular structures of endoplasmic reticulum.

Microfilaments have a contractile function.

Aleuroplasts are protein-storing plastids.

A tissue is defined as a group of cells that are similar in structure and work together to perform a specific function in an organism.

 Correct answer is Collenchyma. Collenchyma provides extra structural support, particularly in regions of new growth.

Adipose tissue is a type of connective tissue specialized for storing fat (lipids) in cells called adipocytes.

 Parenchyma serves as a food storage tissue. It stores starch, protein, fats, oils and water in roots, tubers (e.g. potatoes), seed endosperm (e.g. cereals) and cotyledons (e.g. pulses and peanuts).

Fimbriae are larger then pili. These appendages attache bacteria to rock surfaces and host tissue.

Number of Golgi bodies increases during cell division when these organelles secrete materials to form cell plate.

Vacuoles are members of endomembrane system.

Peroxisomal disorders are a class of medical conditions that typically affect the human nervous system as well as many other organ systems.

SER is the major site of lipid biosynthesis.

Golgi bodies are characterised by cis and trans faces.

Golgi bodies are involved in the formation of proteoglycans.

The Golgi apparatus is a major collection and dispatch station of protein products received from the endoplasmic reticulum (ER).
