Day 9 - Cell modifications

Question 1

This is the process that occurs after cell division and these new cells are structurally modified to adapt and respond to the environment

Answer 1

Cell Modification

Question 2

It is a plasma membrane cell that increases the surface area of eukaryotic cell. It is folded in a fingerlike projections. It also has a dense bundle of cross linked actin filament for absorption, secretion, cellular adhesion and mechano-transduction.

Answer 2

Microvilli

Question 3

It is has tail like projections to prevent accumulation of dust creating thin layer of mucous along tubes. It is usually found in the lungs and fallopian tube

Answer 3

Cilia

Question 4

It is the sweeper of cilia. It is used to move cells

Answer 4

Motile Cilia

Question 5

This cilia is used to trap dirt and it is usually found in the eyes and nose

Answer 5

Non- Motile Cilia

Question 6

This cilia is closely related to microvilli. This responds to fluid pressure and it turns into electric messages and neuronal signals. It is Mechano-sensing organelle.

Answer 6

Stereo Cillia

Question 7

This cell is used for contraction and movement. It is elongated and elastic . It also has a lot of mitochondria

Answer 7

Muscle Cell

Question 8

It is a tiny disc-like cell (biconcave shape) and it has no nucleus. It has hemoglobin which explains the red color of this cell.

Answer 8

RBC

Question 9

In how many months does this RBC break down and changes to what color exerted in the bile.

Answer 9

in 4 months it breaks down and changes to yellow in the bile.

Question 10

Where was RBC originated?

Answer 10

At the bone marrow

Question 11

It is the epidermal cells of the roots and it keeps intimate relationship with the soil. It increases its size of the root’s surface area for more absorption by active transport.

Answer 11

Root hair cells

Question 12

It is the hairlike outgrowths that reduces evaporation by covering stomata openings. It also protects the plant from high intensity light and UV rays.

Answer 12

Trichomes

Question 13

It is sausage shaped cell flanking stoma. It has a mouth shaped epidermal opening and it contain chloroplast. It also has turgor driven valve that opens and close pores

Answer 13

Guard cells
