Animal cell (eukaryotic cell).

Question 1

Animal cell organelles.

Answer 1

Nucleus.
Rough endoplasmic reticulum.
Smooth endoplasmic reticulum.
Golgi body.
Lysozomes.
Centrioles.
Mitochondria.

Question 2

Nucleus structure and function.

Answer 2

Nuclear envelope: Seperates nucleus and cytoplasm.
Nuclear pores: Allows MRNA to leave the nucleus.
Nucleoplasm: DNA attached to histone proteins (DNA wrapped around histone=chromatin).
Nucleolus: Produces ribosomes.

Question 3

Rough endoplasmic reticulum structure and function.

Answer 3

S: Studded with 80s ribosomes, attached to the nucleus, made of flattened sacs called Cisternae (attached).
F: Site of protein synthesis and transports proteins (makes vesicles out of phospholipids that contain proteins made in the rer which then go to the golgi body).

Question 4

Smooth endoplasmic reticulum structure and function.

Answer 4

S: Cisternae but no ribosomes.
F: Produces lipids.

Question 5

Golgi body/apparatus structure and function.

Answer 5

S: Semicircular Cisternae (not attached).
F: Modifies proteins (adds on things and makes sure they are correct).

Question 6

Lysozomes structure and function.

Answer 6

S: Vesicles containing digestive enzymes.
F: Digests and recycles damaged organelles.

Question 7

Centrioles structure and function.

Answer 7

S: 2 perpendicular tubes next to the nucleus.
F: Produces fibres that are needed in cell division (spindle).

Question 8

Mitochondria structure and function.

Answer 8

S: Outer membrane, Inner mebrane, Intermembrane space, 70s ribosomes, Matrix (own cytoplasm), Cristae (folded inner membrane).
F: Aerobic respiration to produce ATP (to store energy).
