Function Of Cell Organelles

Question 1

Autolysis

Answer 1

Lysosomes break down and digest the old organelles.

Question 2

Thylakoid

Answer 2

Double membranes sac with highly folded inner membrane, which contains chlorophyll molecules

Question 3

Granum

Answer 3

Thylakoid membranes form stacks called grana for efficient light absorption.

Question 4

Lamellae

Answer 4

This is the double membrane that links thylakoid with granum

Question 5

Stroma

Answer 5

Liquid containing enzymes for photosynthesis and synthesising starch grains from glucose

Question 6

Circular DNA

Answer 6

Contains genetic code for proteins/ enzyme synthesis, needed for photosynthesis and chloroplast is self replicating

Question 7

Cellulose

Answer 7

Makes up 50% of plant cell wall which forms microfibrils.

Question 8

Plasmodestmata

Answer 8

Pores which connects the cytoplasm of adjacent cells, allowing easy exchange between two cells.

Question 9

Tissue

Answer 9

A group of cells that have a similar structure that work together to perform the same function.

Question 10

Epithelium tissue

Answer 10

Lines the spaces in animals: cuboidal and ciliated epithelial

Question 11

Muscle tissue

Answer 11

Contracts and relaxes to move parts of animals. Striated and smooth muscle

Question 12

Connective tissue

Answer 12

Structural tissue in animals eg collagen

Question 13

Phagocytosis

Answer 13

Vesicles fuse with the membrane of cell vacuoles and the enzymes digest the contents, which have previously enclosed by phagocytosis
