introduction to the Cell

Question 1

is regarded as the “unit basic of life”

Answer 1

Cell

Question 2

The term “cell” was coined by blank based on his microscopic observation of a piece of cork.

Answer 2

Robert Hooke

What are the Cell Theories

Answer 3

All organisms are made up of cells.
Cells are the unit of organization of all organisms.
Cells arise from pre-existing cells.

Question 4

Answer 5

LUCA (Last Universal Common Ancestor)

Question 6

LUCA is otherwise known as?

Answer 6

Progenotes

Question 7

Are those organized specialized structures that are found in a living cell.

Answer 7

Organelles

Question 8

Several organelles are always found in all types of eukaryotic cells and there are also those that are uniquely found in certain types of eukaryotic cells.

Answer 8

False

Question 9

Is for the storage genetic information and assembly of ribosome units. It has a double membrane called an envelope.

Answer 9

Nucleus

Question 10

In the envelope are openings called?

Answer 10

Nuclear pores

Question 11

Do not have a membrane and are a complex of RNA and proteins. It functions for protein synthesis specifically translation.

Answer 11

Ribosome

Question 12

Is bound by a single membrane that contains receptor for the entry of selected proteins. It functions for protein synthesis and processing.

Answer 12

Rough Endoplasmic Reticulum

Question 13

Is also bounded by a single membrane that contains enzymes for synthesizing phospholipids.

Answer 13

Smooth Endoplasmic Reticulum

Question 14

Is also bounded by a single membrane that contains receptor for products of rough ER. Composed of a stack flattened cisternae. Functions for processing protein, Lipids, and organic compounds.

Answer 14

Golgi Apparatus

Question 15

Is the digestion and recycling of the cell. It contains proton pumps. Inside are acid hydrolases that catalyze hydrolysis reactions or the breakdown of organic compounds.

Answer 15

Lysosomes

Question 16

Functions for the oxidation of fatty acids, ethanol and other compounds. A single membrane that contains transporter for the selected macromolecules. Inside are enzymes that catalyzes oxidation reactions like Catalase that processes peroxides.

Answer 16

Peroxisomes

Question 17

It could contain compound for coloration like pigments or could be a storage of oils, carbohydrates water or toxins. It is covered by a single membrane that contains transporter for selected molecules.

Answer 17

Vacuoles

Question 18

Is regarded as the “powerhouse of the cell” because the energy in the form of ATP is produced here, Bound by a double membrane.

Answer 18

Mitochondrion (singular for mitochondria)

Question 19

Is the primary source of energy used to fuel various cellular processes.

Answer 19

ATP (Adenosine Triphosphate)

Question 20

Functions for the production of ATP and sugars via photosynthesis. Contains pigment that harvest light energy and enzymes that catalyzes redox reactions.

Answer 20

Chloroplast

Question 21

Is not enclosed in a membrane. It is composed of actin filaments, intermediate filaments, and microtubule. It is function for structural support, movement of materials within the cell.

Answer 21

Cytoskeleton

Question 22

It is a single membrane composed of phospholipid bilayer that contains transport and receptor proteins.

Answer 22

Plasma membrane

Question 23

plasma membrane is also known as?

Answer 23

Cell membrane

Question 24

Provides protection and structural support to certain types of cells. It is not membrane-bound. It is composed of carbohydrates fibers running through a carbohydrate or protein mass.

Answer 24

Cell wall

Question 25

Organelles that plants have that does not found in animals.

Answer 25

Chloroplast
Cell wall
Central vacuole

Question 26

Organelles that are found in animal that and does not found in plants

Answer 26

Lysosomes
Flagellum
Centriole
