Q2.
Read these passages from the text and answer the questions that follow.
Plant Tissues
All three types of plant cells are found in most plant tissues. Three major types of plant tissues are dermal,
ground, and vascular tissues.
Dermal Tissue
Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. You can think of
the epidermis as the plant’s skin. It mediates most of the interactions between a plant and its environment.
Epidermal cells secrete a waxy substance called cuticle, which coats, waterproofs, and protects the
aboveground parts of plant. Cuticle helps prevent water loss, abrasions, infections, and damage from toxins.
Ground Tissue
Ground tissue makes up much of the interior of a plant and carries out basic metabolic functions. Ground
tissue in stems provides support and may store food or water. Ground tissues in roots may also store food.
CLASS-IX-9
www.hallmarkpublicschool.com
Vascular Tissue
Vascular tissue runs through the ground tissue inside a plant. It consists of xylem and phloem, which
transport fluids. Xylem and phloem are packaged together in bundles.
Questions
1. What is a plant’s epidermis? What is its function?
2. Describe the functions of ground tissue.
3. Why are xylem and phloem bundled together?
4. Do you think that all plants have these three types of tissue? Why or why not?
Q3.
Fill in the blank with the appropriate term.
1. The __________ contains chlorophyll.
2. A membrane-bound organelle containing pigments other than chlorophyll is the __________.
3. The __________ contains dividing, undifferentiated cells.
4. __________ consists of loosely packed cells with thin cell walls.
5. The tissue type that makes up most of the plant’s interior is __________.
6. The epidermis makes up the __________.
7. The __________ provides support for individual plant cells and for the entire plant.
8. The __________ contains xylem and phloem.
9. The __________ contains cells with thick, lignified cell walls.
10. The water-filled, membrane-bound __________ occupies the majority of space inside a mature
plant cell.
11. __________ helps support the plant and provides wind-resistance; its cells have irregularly thickened
cell walls.
12. The plant’s __________ protects the plant against water loss, toxins, abrasions, and infections.

PHYSICS
GENERAL INSTRUCTIONS
A:Use a sharpen pencil to plot graphs.
B:Use appropriate scale of time, displacement and velocity while plotting graphs.
Q1.
The following paragraph compares the performance of a magnetically levitated train (theTransrapid)
to a conventional high speed passenger train (the ICE).
CLASS-IX-12
www.hallmarkpublicschool.com
The Transrapid is not only fast, but it can also accelerate quickly to high speeds 300 km/h (185 mph) can be
reached after a distance of only 5 km (3 miles).Modern high-speed trains require more than 28 km
(18 miles) and at least four times as long to reach the same speed.How does the acceleration of the
Transrapid compare to the acceleration of the ICE?
Q2.
Cars cruise down an expressway at 25 m/s. Engineers want to design an interchange for a
deceleration of −2.0 m/s2 over 3.0 s.
(a) What velocity will cars have at the end of the approach?
(b) What minimum approach length will satisfy these requirements?
(c) What maximum velocity could a car entering the interchange have and still be able to exit at the
intended velocity? (Assume an extreme deceleration of four times the usual rate)
Q3.
The exercise consists of three small and one large velocity-time graph.
Complete the three small velocity-time graphs from the information provided below each graph. The larger
velocity-time graph shows the motion of some hypothetical object over time. Break the graph up into
segments and describes qualitatively the motion of the object in each segment. Whenever possible, calculate
the acceleration of the object as well.
Q4.
We give you an example of the cross- country race event for two runners.
