Question 3

State 3 theory cell from scientists

Answer 3

-all plants are made of cells
-all animals are made of cells
-all cells come from pre-existing cells

Question 4

State 3 theory cells of biology

Answer 4

-all living things are made up of cells
-cells are the basic unit of structure and function in organism
-new cells are produce from existing cells

Question 5

Theory of Abiogenesis (non-living)

Answer 5

Theory state that non-living things can be spontaneously changed into living things

Question 6

Theory of Biogenesis

Answer 6

States that only living organisms can produce other living organisms

Question 7

Means of Cell Specialization

Answer 7

Cell in organism specialized to perform different tasks.

Question 8

State characteristic of Prokaryotes [6]
(not true nucleus)

Answer 8

-including bacteria
-no nucleus
-no membrane
-have a long circular DNA
-contain ribosome to make proteins
-rod shape, spherical, and spiral

Question 9

Prokaryotes cell structure [6]

Answer 9

-small
-capsule on the 1st layer
-cell wall on the 2nd layer made of peptidoglycan (carbo + protein)
-plasma membrane on the 3rd layer
-DNA in a region called nucleoid
-use flagella to move in rotary corkscrew

Question 10

State the characteristic of Eukaryotes [7]

Answer 10

-exclude bacteria
-more complex and larger than Prokaryotes
-have membrane bound organells
-has a nucleus
-has more DNA than Prokaryotes
-DNA is linear
-ex: animal, plant, fungi

Question 11

Eukaryotes Cell structure [2]

Answer 11

-have a membrane bound nucleus
-has a numerous bound organells not found in Prokaryotes (mithochondria, lysosomes, golgi apparatus)

Question 12

Differences between Prokaryotes and Eukaryotes

Answer 12

Prokaryotes:
-no nuclues
-small ribosomes
-no organelles
-ex: in archaebacteria, eubacteria

Eukaryotes:
-have nucleus
-large ribosomes
-have organelles
-ex: in protista, fungi, plantae, animalia

Question 13

Means of Prokaryotic and Eukaryotic

Answer 13

P= not true nucleus
E= true nucleus

Question 14

Basic organelles of cells [4]

Answer 14

-cell membrane
-cythoplasm
-ribosomes
-nuclear material

Question 15

Similarities between Plant Cells and Animal Cells
[3]

Answer 15

-have membrane surrounding cythoplasm
-both have nucleus
-both have mytochondria

Question 16

Difference between Multicellular and Unicellular [3]

Answer 16

composed by a single cell (UNI)
composed by numerous cell (MULTI)

Prokaryotic (UNI)
Eukaryotic (MULTI)

injury of the cells can cause death (UNI)
injury or death of the cell can be replace with new cell (MULTI)
