Primary Components of Human Cells

Question 1

Cytoplasm

Answer 1

Contains many suspended organelles or cell structures

(medium for chemical reactions)

Question 1

Plasma membrane function

Answer 1

Separates the internal components of the cells from the surrounding environment

(essential to the life of the cell)

Question 2

Nucleus

Answer 2

control center of the cell

regulates cell activity

houses genetic material

Question 3

Nuclear membrane

Answer 3

Protects the nucleus, allowing in only specific materials

Question 4

Nucleolus

Answer 4

Forms RNA and ribosomes

Question 5

Mitochondria

Answer 5

Convert nutrients into energy for use by the cell.body

creates adenosine triphosphate (ATP)

Question 6

Ribosomes

Answer 6

Protein syntheis for both internal and external use

Question 7

Endoplasmic Reticulum

Answer 7

Transports material throughout the cell

RER: Supports the synthesis and transport of proteins

SER: Supports the synthesis of some lipid molecules, including steroids

Question 8

Golgi Apparatus

Answer 8

“Packaging and shipping plant” of the cell

Packages and releases materials secreted by the cell for external use

Forms lysosomes for sure within the cell

Question 9

Lysosomes

Answer 9

Digest waste materials including damaged materials found in the cell, old cell components, and materials entering the cell

Question 10

Cytoskeleton

Answer 10

Maintains the shape and structure of the cell

(Keeps organelles in place and moves them throughout the cell as needed)

Question 11

Centrioles

Answer 11

Participate in cell reproduction through the distribution of DNA to new cells

Question 12

Cilia

Answer 12

Aid in the movement of substances along the surface of the cell

Question 13

Flagella

Answer 13

Move the cell itself, through a whip-like motion
