C2 Organelles And Functions

Question 1

What is the function of the Cell Membrane?

Answer 1

Protective Barrier for the cell: allows transport of needed materials into the cell and waste out (important for cell interaction and communication)

Question 2

Nucleus

Answer 2

Contains DNA, and directs all cellular activities (controls everything that happens in the cell), it has a nuclear envelope allowing transport of materials

Question 3

Cytoplasm

Answer 3

Gel like material that suspends the other organelles and contains nutrients

Question 4

Endoplasmic reticulum

Answer 4

Tube structure + transports materials
Rough ER = ribosomes make protein
Smooth ER = Makes oils and lipids + other fats

Question 5

Ribosomes

Answer 5

Round and synthesizes proteins and turns amino acids into proteins. Usually connected to ER or wandering around cell

Question 6

Golgi Apparatus

Answer 6

Creates vesicles for particles to transport out the cell like a package (receives substances from ER)

Question 7

Lysosomes

Answer 7

Only found in animals, it protects the organelles from bacteria and produces digestive enzymes. Destroys damaged cell organelles.

Question 8

Mitochondria

Answer 8

Powerhouse of the cell. Uses cellular respiration to convert chemical energy from sugar into useful energy. Oval like + 2 membranes

Question 9

Centrioles

Answer 9

Only in animal cells, it is used for meiosis and mitosis. The fibers are used for cell division (splitting chromosomes)

Question 10

Vacuoles/vesicles

Answer 10

Stores nutrients and transports material around the cell. Acts as a storage space and are bigger in plants than animals (cells)

Question 11

Cell wall

Answer 11

Provides structure for plants, helps plant stand, and protects the organelles (that is held by cytoplasm)

Question 12

Chloroplasts

Answer 12

Only in plants and contain chlorophyll which makes green colour. Photosynthesis happens here and results in glucose, H2O, and O2
