Question

use your textbook and the lab sheet to complete the following. activity: identifying parts of the cell fill in the table describing the areas of the nucleus. name picture function nuclear membrane nucleolus chromatin nuclear pores activity: identifying components of the plasma membrane. in the space below, draw a sketch of the plasma membrane. then fill in the table describing the parts of the membrane. name function phospholipid bilayer forming the lipid bilayer of cell membrane, acting as selective barrier and enable cellular process proteins facilitate metabolism microvilli increase surface area for absorption

Explanation:

The nuclear membrane is a double - layered structure that surrounds the nucleus, protecting the genetic material (DNA) and controlling the movement of substances in and out of the nucleus. The nucleolus is the site of ribosome synthesis within the nucleus. Chromatin is the complex of DNA and proteins that condenses to form chromosomes during cell division and contains the genetic information. Nuclear pores are channels in the nuclear membrane that allow the passage of molecules such as RNA and proteins between the nucleus and the cytoplasm. For the plasma membrane components, the phospholipid bilayer forms the basic structure of the membrane, providing a barrier and enabling cellular processes. Proteins in the plasma membrane can act as transporters, receptors, etc., facilitating metabolism. Microvilli are small, finger - like projections that increase the surface area of the cell for absorption.

Answer:

Name	Picture	Function
Nucleolus	(Sketch of a dense area within nucleus)	Site of ribosome synthesis
Chromatin	(Sketch of thread - like structures within nucleus)	Contains genetic information
Nuclear Pores	(Sketch of small holes in nuclear membrane)	Allow molecule passage between nucleus and cytoplasm
Phospholipid Bilayer	(Sketch of two - layer structure)	Forms basic membrane structure, provides barrier, enables cellular processes
Proteins	(Sketch of various shapes embedded in membrane)	Facilitate metabolism
Microvilli	(Sketch of finger - like projections)	Increase surface area for absorption
