Chapter 5: Cell Structure Organization And Levels Of Organization

Question 1

Features of cell surface membrane

Answer 1

It’s separates the interior of all cells from the outside environment.it is a barrier keeping the constituents of the cell in in and unwanted substances out

Question 2

Features of Nucleus

Answer 2

The location of the nucleus can vary depending on the type of the cell

Question 3

The functions of a cell surface membrane

Answer 3

It is selectively permeable and controls the movement of substances into an out of the cell across the membrane
It forms a period between the cell and its surroundings
It keeps the contents of the cell inside
The membrane has receptors to perform the functions of cell recognition

Question 4

The location of the cell surface membrane

Answer 4

It surrounds the cytoplasm of all cells
In animal cells it is the outermost layer of the cell
Implant a cell wall surrounds the cell membrane

Question 5

The location of the nucleus

Answer 5

The usual location of the nucleus is at the center of animal cells and in plant cells it’s usually at the edge periphery

Question 6

The function of the nucleus

Answer 6

The nuclear is the control center of the cell and controls the functions and activities of the cell
it stores genetic information of the cell
it is thus responsible for the transmission of genetic information from the parent cell to its daughters cells
it produces an exact copy when cells divide and passage genetic information to new cells

Question 7

The function of chloroplast

Answer 7

Coloroplast are the site of photosynthesis they convert light energy from the Sun into chemical energy to form glucose
Chloroplast absorbs light energy and they contain chlorophyll which traps light energy

Question 8

Location of chloroplast

Answer 8

Chloroplast are located in the cells of green plants
They are spread throughout the cytoplasm
There are mostly located at the edges of the cell to maximize light of absorption and photosynthesis rate

Question 9

The cell structure of the cell surface membrane

Answer 9

It’s separates the interior of all cells from the outside environment
It is a barrier keeping the constituents of the cell in an unwanted substances out

Question 10

Cell structure of a cell wall

Answer 10

It is fully made of cellulose
It is fully permeable

Question 11

Functions of a cell wall

Answer 11

The cell wall provides mechanical support strength and protection around the plant cell it gives the plant cell a specific shape it resists turgor pressure and programs the bursting of plant cells

Question 12

The location of the cell wall

Answer 12

Tell us are located around the cell surface membranes of plant cells it is situated outside the cell membrane plant cells are there for surrounded by cell walls in addition to the cell membrane

Question 13

The cell structure of a vacuole

Answer 13

It is surrounded by the tonoplast
Water flowing in and out of the vacuole is regulated by the tonoplast
Vacuoles are found permanently in plant cells
Animal cells may possess small vacuoles which are temporary structures
Vacuoles is filled with cell sap

Question 14

Functions of a vacuole

Answer 14

The vacuole store salts ions sugars waste products enzymes and pigments in the cell sap
It’s supports the plant cells and keeps the cell firm turgid
A controls the water content of the plant cell regulates osmotic properties of the cells (the flow of water inwards and outward)

Question 15

The location of a vacuole

Answer 15

Small temporary vacuoles in animal cells are located in the cytoplasm of the cell
They can be numerous no vacuoles in the cytoplasm of the animal cell
Plant cells have one large vacuole situated near the nucleus of the plant cell they may be more than one vacuole

Question 16

Cytoplasm cell structure

Answer 16

Cytoplasm is not a cell structure but an organelle

Question 17

Functions of a cytoplasm

Answer 17

Cytoplasm is a jelly like fluid which is the site for chemical reactions inside the cell where all the work of the cell is done
The cytoplasm is composed manure of water and contains enzymes cells organelles and various organic molecules
Does cytoplasm also provides a physical structure for the plant

Question 18

Location of a cytoplasm

Answer 18

The cytoplasm is located within a sales membrane but not inside the cells nucleus all the contents of the cells are contained within the cytoplasm

Question 19

The similarities between animal and plant cells,

Answer 19

They both have a nucleus, cytoplasm, cell surface membrane and mitochondria. Both have also Golgi bodies, secretary vesicles comma rough endoplasmic reticulum and ribosomes

Question 20

Muscle tissue

Answer 20

Muscle tissue is a soft tissue that composes muscles in the animal bodies and gives a rise to the ability of muscles to construct

Question 21

Cardiac muscle

Answer 21

Tissue that forms the bulk wall of the heart

Question 22

Smooth muscle

Answer 22

Tissue is located in the walls of the hollow internal structures such as black vessels, the stomach, intestine’s and urinary bladers.

Question 23

Skeletal muscles

Answer 23

Is named for its location it is attached to bones and powers the movement of the skeleton comma as in walking and lifting

Question 24

cell structure features of Rough endoplasmic reticulum

Answer 24

The rough endoplastic reticulum has ribosomes attached to its surface which gives it a rough appearance

Question 25

Functions of a rough endoplasmic reticulum

Answer 25

A transport mrna from the nucleus to the ribosomes
It’s synthesizes ribosomes
It’s synthesizes proteins
It transports proteins to the rest of the cell

Question 26

Cell structure of a ribosome

Answer 26

Ribosomes are attached to the rough endoplasmic reticulum which gives it a rub appearance

Question 27

Functions of a ribosome

Answer 27

It is the site of protein synthesis which means they make proteins by combining different amino acids together

Question 28

Functions of a mitochondria

Answer 28

Mitochondria are the site of aerobic respiration
Mitochondria are the site of ATP synthesis
Provide energy for cell reactions

Question 29

Golgi body with sectory vesicles

Answer 29

Sectory vesicles are produced by Golgi bodies
Secretary vesicle store transport or digestive products and waste
Some vesicles become lysosomes which contain digestive enzymes
These enzymes break down and destroy bacteria and unwanted organelles
Secretary vesicles contain materials that are to be excreted from the cell

Question 30

What is a cell

Answer 30

The cell is the basic structural and functional unit of all known living organisms
A solid the smallest unit of life
It is the building unit in all organisms
All organisms are composed of cells
Salsa often called the building blocks of life
