General Biology : Module 6 Cell Modification

Question 1

This type of tissue lines the internal organs and covers the outside of the body
as skin.

Answer 1

Epithelial

Question 2

This type of tissue includes ligaments, tendons and cartilage.

Answer 2

Connective

Question 3

This type of cell sends messages throughout the body in the form of electrical
impulse.

Answer 3

Nerve Cell

Question 4

This type of cells has no nucleus.

Answer 4

RBC (Red Blood Cell)

Question 5

Cellular adaptation that occurs due to an increase in workload that results in
the number of cells is ___.

Answer 5

Hyperplasia

Question 6

Is attached by tendons to the bones, which helps you to
regulate your movements consciously.

Answer 6

Skeletal Muscle

Question 7

• is found in blood vessel walls, digestive tract walls, uterus, urinary
  bladder and various other internal structures.
• is not striated and its
  involuntary, not under conscious control.

Answer 7

Smooth Muscle

Question 8

• Also called brush/striated border.
• They are finger-like cytoplasmic
  extensions of the apical surface which increase surface area for absorption.
• Numerous and often regularly arranged and found in absorptive epithelia.

Answer 8

Microvilli

Question 9

Appears as short hair-like structures or projections.

The core is
composed of microtubules arranged in specific manner and each cilium is connected
to a basal body and extends from the free surface.

Function is for movement/motility
and it beats in coordinated rhythmical wave-like manner that promotes movement
of materials over the surface.

Answer 9

Cilia

Question 10

They have the same axial structure with cilia but much longer that
also functions with movement. Present in the tail of spermatozoa.

Answer 10

Flagella

Question 11

Basal Modification

Answer 11

Basal Infoldings

Question 12

They support the epithelium and also functions as a passive
molecular sieve or ultrafilter. Present also in mitochondria that suggests active
transport is occurring.

Answer 12

Basal Infoldings

Question 13

Lateral Modification

Answer 13

• Tight Junctions
• Adherens Junction

Question 14

They are intercellular adhesion complexes in epithelia and
endothelia that control paracellular permeability.

This paracellular diffusion barrier
is semipermeable.

Tight junctions form the border between the apical and basolateral
cell surface domains in polarized epithelia and support the maintenance of cell
polarity by restricting intermixing of apical and basolateral transmembrane
components.

Answer 14

Tight Junctions

Question 15

This is an element of the cell-cell junction in which
cadherin receptors bridge the neighboring plasma membranes via their hemophilic
reactions.

The actin filaments which make up zonula adherens maintain integrity of
the cell to better bind.

Answer 15

Adherens Junctions

Question 16

epithelial tissue arrangement for secretion

Answer 16

Cuboidal

Question 17

specialized pores for exchange of gas

Answer 17

Stomata

Question 18

Brings water and nutrients from the roots to various parts of the plant.

Answer 18

Xylem

Question 19

Covers and protect the plant and monitors exchange of gases.

Answer 19

Dermal

Question 20

Serves mainly for promoting neuronal activity.

Answer 20

Glia

Question 21

Known as nerve cells.

Answer 21

Neurons

Question 22

Which of the following types of tissue is responsible for body movement?

Answer 22

Muscular

Question 23

Which of this tissues support the young plants and woody plants?

Answer 23

Collenchyma Tissue

Question 24

Spermatozoa is propelled by ___.

Answer 24

undulating thread-like flagellum

Question 25

Which of the following statements is NOT true about why red blood cells lack
a nucleus?

a. Nucleus is the control center of the cell.
b. Enabling more oxygen to be transported in the blood.
c. Enables the red blood cells to contain more hemoglobin.
d. A specialized adaptation of RBC to be able to perform its function.

Answer 25

a. Nucleus is the control center of the cell.

Question 26

Which of the following statements is NOT a cell modification that leads to
adaptation?

a. Plant cells have a large amounts of the chloroplast which allows the cell to
undergo photosynthesis.
b. Muscle cells are made up primarily of a pair of special proteins called actin
and myosin which allows muscle to contract.
c. Nerve cells have specialized structure called dendrites which receive an
electrical signal from another neuron and an axon which transmits the
electrical signal to another neuron.
d. None of the above.

Answer 26

None of the Above
