Q:

What are the functions of glycoproteins?

A:

Glycoproteins provide many functions: they give structural support to cells, help to form connective tissues and facilitate digestion by producing secretions and mucous in the gastrointestinal tract. Glycoproteins are handy cell components and are found in many places within cells.

Glycoproteins are located in cell walls, blood plasma and connective tissues, and they have fine structural differences depending on their location. They also play key roles in reproduction and occur on the surface of spermatozoa, increasing the likelihood of a sperm cell’s attraction to eggs by altering the permeability of plasma membranes. These proteins may also adhere to cells and enable development of functional tissues in the body.

    What two functions do nucleic acids have?

    A:

    According to About.com, two functions of nucleic acids are passing genetic information to the new generations (new cells within an organism or offspring) and coding in protein synthesis.

    Why do plant cells have bigger vacuoles than animal cells?

    A:

    Plant cell vacuoles serve the same vital storage functions for nutrients, water and wastes as those in animal cells but are much larger because they also provide structural stiffness in combination with the plant's cell walls. This is why water-starved plants droop; their cells have essentially deflated. If a living but wilted plant once again receives sufficient water, it regains its former stiffness as the vacuoles refill.
