Structure Answer Key — Section 7 2 Eukaryotic Cell

A double-membrane layer that surrounds the nucleus, dotted with pores that allow material to move in and out.

: Known as the "powerhouses" of the cell, they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.

: Literally "little organ"; specialized structures within a cell that perform specific functions.

A small, dense region within the nucleus where the assembly of ribosomes begins. Organelles that Build Proteins section 7 2 eukaryotic cell structure answer key

Answer : Cell walls and chloroplasts (though some protists have them too). Large central vacuoles are also more prominent in plants.

: Small organelles found throughout the cytoplasm, on the ER, or attached to the nuclear membrane, and are responsible for protein synthesis.

: Involved in the formation of cilia, flagella, and the spindle fibers that separate chromosomes during cell division. A double-membrane layer that surrounds the nucleus, dotted

Use this list to answer typical questions: Nucleus, Ribosome, Rough ER, Smooth ER, Golgi, Mitochondria, Lysosome, Vacuole, Chloroplast, Cell Wall, Cytoskeleton.

Answer : It is the specific region within the nucleus where the assembly of ribosomes begins.

Describe two structural differences between a plant cell and an animal cell. A small, dense region within the nucleus where

Trace the path of a protein made by a ribosome on the Rough ER until it is secreted from the cell.

: A complex of flattened sacs and associated tubules adjacent to the endoplasmic reticulum. It modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
