Unit 1 RETAKE ANIMAL CELLS

Question 1

What does both animal and plant cells contain?

Answer 1

cell membrane, cytoplasm, nucleus

Question 2

What is only in plant cells?

Answer 2

cell wall, chloroplast, vacuole

Question 3

What is the structure/function of the endoplasmic reticulum?

Answer 3

flattened membrane bound sacs that are continuous  smooth ER is involved with making lipids
rough ER (RER) transports made on attached ribosomes

Question 4

What is the structure/function of the Golgi apparatus?

Answer 4

stack of membrane-bound, flattened sacs
receives proteins from the ER, adds sugar (modify)
packages proteins into vesicles that can transported inside cell or outside.

Question 5

What is the structure/function of mitochondria?

Answer 5

2 membranes separated by a fluid filled space, inner membrane is folded to form cristae, central part is the matrix.
where ATP is produced for respiration

Question 6

What is the structure/function of a lysosome?

Answer 6

spherical sacs surrounded by a single membrane
contains digestive enzymes.
a acrosome is a specialised lysosome in the head of the sperm cell which helps penetrate the egg.

Question 7

What is the structure/function of ribosomes?

Answer 7

very small organelles in the cytoplasm attach to the ER

site of protein synthesis

Question 8

What is the structure/function of centrioles?

Answer 8

small protein tubes of microtubules

forms spindles in cell division which separates chromosomes.
