different types of cells in the human body based on tissue formation

Question 1

• toughest body cells as they are bound together by calcium and phosphate
• give strength, support, and framework to the body by enclosing organs in the skeletal system

Answer 1

bone cells (osteocytes)

Question 2

• freely bendable
• present in ear bone, in between large bones to help it bend and move freely like in between two ribs,
  spinal bones, and joints

Answer 2

cartilage (chondrocytes)

Question 3

• very long and have many branching at either end
• it never multiplies
• present all over the body and sometimes as long as a few meters long

Answer 3

nerve cells

Question 4

serve as a barrier for pathogens, fluid loss, and mechanical injuries

Answer 4

epithelial cells

Question 5

mostly long, and large, and have the ability to contract and relax providing movements

Answer 5

muscle cells

Question 6

three types of muscle cells

Answer 6

skeletal, cardiac, and smooth muscles

Question 7

are attached to long bones and assist in their movement (muscle contraction)

Answer 7

skeletal muscle cells

Question 8

present only in the heart muscle and are responsible for heartbeats

Answer 8

cardiac muscle cells

Question 9

flexible yet can contract and relax, present in the stomach, intestine, and blood vessel walls which help in the movement of food through the gut

Answer 9

smooth muscle cells

Question 10

they form glands and secrete something important

Answer 10

secretory cells

Question 11

• can be seen in the soles palms and bums
• it reduces friction to the body

Answer 11

adipose cell

Question 12

they are always motile, have a limited lifespan

Answer 12

blood cells

Question 13

special type of cells

Answer 13

sperm cells
oocytes (egg cells)
stem cells
rods and cones
ciliated cell

Question 14

have tails which allow it to swim and move in the female uterus

Answer 14

sperm cells

Question 15

• present in the adult female genital system
• start to mature after puberty and continue till menopause

Answer 15

oocytes

Question 16

these are given so much importance due to their promising role in the treatment of disorders in the future

Answer 16

stem cells

Question 17

present in the eyes and have the capacity to capture image color and light

Answer 17

rods and cones

Question 18

• present in the lining of the respiratory tract and esophagus
• have pointed thread-like cilia that move in one particular direction to pass material

Answer 18

ciliated cell

Question 19

• facilitate the acquisition of their needs and their adaptations to a changing environment
• it occurs after cell division

Answer 19

cellular modifications

Question 20

cell modification found on the apical surface of the cell

Answer 20

apical modification

Question 21

use these modifications to move to an area that is favorable for their growth or to target cells

Answer 21

flagella and cilia

Question 22

are modifications that enable bacteria to adhere to tissue surfaces, mostly for the exchange of materials during reproduction

Answer 22

pili

Question 23

they help to increase surface area allowing for faster and more efficient absorption

Answer 23

villi and microvilli

Question 24

bulge outward to move the cell or engulf prey

Answer 24

pseudopods

Question 25

for defense mechanisms against heat, high pressure, and stress

Answer 25

spore

Question 26

responsible for transmitting electrical signals

Answer 26

dendrites and axons of the nerve cells

Question 27

permit the muscle to contract and elongate for organisms’ activity

Answer 27

actin and myosin

Question 28

RBCs do not contain a nucleus but contain a large amount of hemoglobin to transport oxygen throughout the body

Answer 28

enucleated RBC

Question 29

play an important role in plant nourishment by enabling the absorption of minerals and water in the environment

Answer 29

root hairs
