SHORT ANSWER QUESTIONS
QUESTION 1
X A & XB
I.Digestive Enzymes (X A)


II.Hydrochloric Acid (X B)
State the role of the following in human digestive system :
I)Digestive enzymes – Foods need to be broken into their
small or simpler


molecules so that they can be absorbed into the
bloodstream. However, the physical breakdown of food is
not enough. Enzymes are hence needed for the chemical
breakdown of food and speeding up the digestive process.
The products of digestion can hence be small enough to be
absorbed.


(ii) Hydrochloric acid – Hydrochloric acid helps to kill the
germs which might have entered in to the system through
food. It creates acidic medium for the pepsin to act on food
to breakdown proteins.
QUESTION 2
X A
Explain how does the exchange of
gases occur in plants across the
surface of stems, roots and leaves.
In plants there are tiny pores called stomata
on leaves and lenticels in stem which
facilitate the exchange of gases. Carbon
dioxide is taken in and oxygen given out
{during photosynthesis} and vice versa
during respiration.
QUESTION 3
X B
How are water and minerals
transported in plants ?
Water and minerals are transported within the
plant by the Xylem vessels (mainly in an upward
direction); these are part of the vascular system
which also includes Phloem vessels.Phloem
transports the products of photosynthesis
within the plant, to all parts like the stem, roots,
fruits etc. in all directions.
QUESTION 4
X A
Describe brie
f
ly the excretory system
of a man.
Excretory System of man consists of a pair of kidneys, a
pair of ureters , a urinary bladder and a urethra.


Kidneys:- They are paired bean shaped glandular organs
located in the abdominal cavity. Each Kidney measure
about 10-12 cm in length ,5-7 cm in breath and 2-3 m in
thickness. In adults it weighs about 120-170 g. Each kidney
has large number of
f
iltration units called nephrons.


Ureters:-It is a thin, narrow muscular tube that emerges
from each kidney. It runs dorsally along the abdominal wall
and open into the urinary bladder.


Urinary Bladder:-It is a hollow, muscular thick walled pair
pear shaped sac like structure which lies in the pelvic
region of the body. It the reservoir for the urine.
QUESTION 5
X B
EXPLAIN PATHWAY FOR TRANSPORT OF
WATER.
Water conducting system in plants is Xylem. It is present in
root ,stems ,branches and leaves .


The root cells that are in close contact of soil actively uptake ions.


This creates a difference in concentrations of ions in root cells and soil.
Due to which the water moves into the root cells to remove this difference.


This forms a water column in the xylem tissue and is steadily pushed
upwards. This is called root pressure.


When the plants lose water through stomata present in the leaves called
Transpiration. This causes a suction pressure and pulls the water column
upto leaf cells.


Thus, the water in plants is transported by these physical forces i.e. the
root pressure ans suction pull.

QUESTION 1
X A/ X B
Why is di
ff
usion not su
ff
icient to meet
oxygen requirement of all the cells in
multicellular organisms ?
All living cells are not in direct contact with
environment. Diffusion is a slow process and it will
take very long time, days and months, to reach every
living cell inside the body of a multicellular organisms.
QUESTION 2
X A/ X B
State the Di
ff
erence between Blood
and Lymph .(State any 3 di
ff
erences)
QUESTION 3
X A/ X B
State the Di
ff
erence between Chyme
and Chyle.
Chyme is the partially digested food and
chyme after digestion in small intestine is
called Chyle.
