Organelles And Their Functions

Question 1

Cell wall

Answer 1

Rigid layer of NON-LIVING material. Supports and protects the cell. Only found in a plant cell.

Question 2

Cell membrane

Answer 2

The innermost living layer of the cell. Helps give shape and supports the cell. Permeable layer (materials can pass through it.) regulates the transport of materials in and out of the cell

Question 3

Cytoplasm

Answer 3

The liquid jelly-like contents of the cell outside of the nucleus. Provides support for the cell and its organelles. Living matter

Question 4

Mitochondria

Answer 4

The powerhouse of the cell. Please for nutrients Molecules are broken down to release energy. The more Energy needed by a cell, The more mitochondria it is likely to have

Question 5

Ribosomes

Answer 5

Tiny knoblike particles in cells that manufacture (make) proteins. Many are attached to the Endoplasmic Reticulum. The proteins made by Ribosomes travel to other parts of the cell

Question 6

Endoplasmic Reticulum

Answer 6

A series of interconnected passageways. Located around the nucleus. Serves as transportation and communication network between the Cytoplasm and the Nucleus

Question 7

Golgi Bodies

Answer 7

Flattened, curved sacs that package, sort, and distribute proteins to the proper locations inside and out of the cell. Located near the Endoplasmic Reticulum.

Question 8

Lysosomes

Answer 8

Sacs formed from the Golgi Bodies. Contains digestive enzymes that break down nutrients. Also breaks down damaged cell parts

Question 9

Vacuoles

Answer 9

Membrane enclosed sacs in plant and animal cells that store food, water, and minerals. Plant cells have large vacuoles and animal cells have small vacuoles.

Question 10

Chloroplasts

Answer 10

Structures in plant cells that contain chlorophyll. Chlorophyll is necessary for photosynthesis to make glucose for the plant

Question 11

Nucleus

Answer 11

Controls all of the cells activities. Contains chromosomes which carries all of the genetic info for the cell

Question 12

DNA

Answer 12

Stands for DEOXYRIBOSE NUCLEIC ACID. DNA is genetic info stored in the nucleus of the cell. DNA is like the instruction manual for the cell

Question 13

Chromosomes

Answer 13

Composed of proteins and DNA (genetic material.) Genes that determine individual traits are located on the chromosomes.
