IV.GIVE REASONS:
1. Micropyle helps in respiration and in the exchange of gases.
ANS- The micropyle is a small opening that is found just close to the hilum and is
retained in the seed after fertilization.When soaked, seeds absorb water mainly through
the micropyle. Micropyle also helps in respiration and in the exchange of gases.

2.Mangroves like Rhizophora and Sonneratia show viviparous

germination.
ANS- Their seeds germinate within fruits while still attached to the parent plant

3. Segregation of waste is important in waste management

ANS- facilitates the process of reuse, recycling, and recovery of waste.

4. Biomedical waste should be incinerated.

ANS- Incineration helps to reduce the toxic content from the waste.

5.Plant cells have definite shape.

ANS- As they have rigid cell wall.

6. Hibiscus is termed as a bisexual flower.

ANS- A hibiscus flower has both male (Stamen) and female (Pistil) reproductive whorls
in the same flower.

7.Joints at the shoulder and hip are classified as freely movable joints.
ANS- The large ball-like head of the HUMERUS fits into the deep socket of the
SHOULDER GIRDLE, thus allowing movement in any direction.

8. Vertebrae is S-shaped.

9. Aerobic respiration is more effective than anaerobic.

ANS- Aerobic respiration occurs in presence of oxygen and there is complete
breakdown of glucose releasing 38 ATP molecules of energy whereas, in anerobic
respiration incomplete breakdown of glucose releasing only 2ATp molecules of energy.

10.Photosynthesis and Respiration are opposite processes.

ANS- Photosynthesis takes in CO2 and releases oxygen whereas cellular respiration
takes in oxygen and releases CO2.
 Hinge joint is present between the bones of fingers and the toes.
11.
ANS- the bones of fingers and toes move in one plane and give sufficient power.

Synovial joints in the knee joint allow considerable movement.

12.
ANS- Synovial joints have:
Ligaments- which holds the joint firmly and prevents dislocation in normal
movement.
Synovial fluid- present between synovial membranes which provides cushioning and
lubrication between the bones.

Hip joint is a ball and socket joint.

13.
ANS- The large ball-like head of the FEMUR fits into the deep socket of the HIP
GIRDLE, thus allowing movement in any direction.

V. ANSWER THE FOLLOWING:

Observe the diagram and answer the following questions:

I. 1. State the aim of the experiment.

Factors essential for germination.
I 2. What does the experiment
. prove?Why?
3 Factors are essential for germination:-

● water - seeds swell and seed coat

ruptures allowing radicle to grow
into root
● Suitable temperature - Optimum
temperature (25 - 350 C)
● oxygen-Energy is available only
by respiration,hence need for
oxygen

1. GIVE REASON:
a. Synovial joints allow
considerable movement.
In the synovial joint, there is a
presence of synovial fluid between the
space of the two bones to provide
lubrication and cushioning effect.

b. The knee joint is held in

position by ligaments
Ligaments- which holds the joint firmly
and prevents dislocation in normal
movement.

1. State the aim of the experiment

Carbon dioxide is produced by green
plants during respiration.

2. Why is lime water added in

flask “C”
To confirm that carbon dioxide is
released only by plants during respiration.
Lime water turns milky.

1. State the aim of the experiment.

CO is released by germinating seeds.

2. GR- seeds taken as control are

boiled and treated with
antiseptic.
Boiled- to kill the seeds
Antiseptic- to prevent bacterial decay on
dead seeds.

1. Identify the plant tissue.

2. Label its parts
A-SIEVE PLATE
B- SIEVE TUBE
C- PHLOEM PARENCHYMA
D- COMPANION CELLS
