QI. Name the following:

Question 1. Two plants that reproduce from spores.
Answer: Ferns and mosses
In simple words: These non-flowering plants produce tiny spores instead of seeds to grow new plants.

Exam Tip: Remember that ferns, mosses, and fungi do not produce flowers or seeds; they rely on spores for reproduction.

Question 2. Two fertilizers which help to get a high yield of crops.
Answer: Urea and NPK (Nitrogen, Phosphorus, and Potassium)
In simple words: Fertilizers are chemical or organic substances added to soil to provide essential nutrients for plant growth.

Exam Tip: Mention common chemical fertilizers or manure like urea, superphosphate, and NPK.

Question 3. Two monocotyledonous seeds.
Answer: Rice and wheat
In simple words: Monocot seeds have only one seed leaf or cotyledon.

Exam Tip: Examples of monocots include cereals like wheat, rice, maize, and grass.

Question 4. Two underground stems.
Answer: Potato and ginger
In simple words: Some plants store food in their stems that grow horizontally underground.

Exam Tip: Do not confuse underground stems like potato with root vegetables like carrot and radish.

Question 5. Two crops grow well on the hill slopes.
Answer: Tea and coffee
In simple words: These crops require heavy rainfall but do not tolerate water stagnation, making sloping hills ideal for their growth.

Exam Tip: Tea and coffee are typical plantation crops grown on sloped terrains.

QII. Fill in the blanks:

Question 1. Growing of plants from any vegetative part of the parent plant is called __________.
Answer: Vegetative propagation
In simple words: New plants are grown from roots, stems, or leaves instead of seeds.

Exam Tip: Learn the exact definition of vegetative propagation for one-word or fill-in-the-blank questions.

Question 2. Seeds that have __________ or __________ stick to the body of animals or birds.
Answer: hooks, spines (or stiff hairs)
In simple words: Spiky or hooked seeds catch onto animal fur or human clothing to get carried to distant places.

Exam Tip: Mention hooks, barbs, or spines as key adaptations for animal dispersal.

Question 3. __________ are chemicals used to destroy harmful insects.
Answer: Pesticides (or insecticides)
In simple words: Farmers spray these chemicals to protect their crops from pests and insects.

Exam Tip: Pesticides target pests, whereas insecticides specifically target insects.

Question 4. Cotton grows well in black __________ soil and jute grows in the light __________ soil.
Answer: cotton, alluvial (or sandy loam)
In simple words: Different crops require specific soil types rich in particular minerals to thrive.

Exam Tip: Black soil is best for cotton; alluvial or loamy soil is best for jute.

Question 5. The practice of growing crops on a large scale is termed as __________.
Answer: Agriculture
In simple words: Cultivating useful plants extensively for food and other products is called agriculture.

Question 1. Match the plants correctly with their reproducing parts.
Column A: a) Sweet potato, b) Bryophyllum, c) Strawberry, d) Mushroom, e) Bougainvillea
Column B: spores, stem cutting, leaves, roots, buds on the runners
Answer:
a) Sweet potato - roots
b) Bryophyllum - leaves
c) Strawberry - buds on the runners
d) Mushroom - spores
e) Bougainvillea - stem cutting
In simple words: Different plants use different specialized plant parts to reproduce and spread.

Exam Tip: Memorize vegetative parts: Bryophyllum uses leaf buds, sweet potato uses tuberous roots, and roses/Bougainvillea use stem cuttings.

QIV. Give reasons:

Question 1. Soaked seed always germinate but not a dry one.
Answer: Water is essential for activating enzymes inside the seed that break down stored food for the baby plant. Dry seeds lack sufficient moisture to trigger these metabolic processes and start growth.
In simple words: Water wakes up the sleeping baby plant inside the seed, which dry seeds cannot do.

Exam Tip: Always mention that water activates enzymes and softens the seed coat during germination.

Question 2. Plants scatter their seeds over a wide area.
Answer: Dispersal of seeds prevents overcrowding. If all seeds fall directly beneath the parent plant, they will have to compete for sunlight, water, minerals, and space, which would stunt their growth.
In simple words: Spreading seeds helps them find enough space, light, and nutrients to grow properly without overcrowding.

Exam Tip: Key terms to include are: overcrowding, competition for resources, and healthy growth.

QV. Write True or False

Question 1. Fibrous outer coat of coconut seeds help them to be easily carried away by water.
Answer: True
In simple words: Coconut shells are fibrous and trap air, helping them float easily across oceans and rivers.

Exam Tip: Water-dispersed seeds typically have spongy or fibrous outer coats to stay afloat.

Question 2. Cotyledons store food for the baby plant.
Answer: True
In simple words: Cotyledons act as lunchboxes for the embryo until it grows green leaves to make its own food.

Question 3. Dandelion seeds are dispersed by water.
Answer: False
In simple words: Dandelion seeds have hair-like structures and are dispersed by wind, not water.

Exam Tip: Feathery or parachute-like seeds are always dispersed by wind (anemochory).

Question 4. Carrot is an underground stem.
Answer: False
In simple words: Carrot is an underground modified root, not a stem.

Exam Tip: Roots grow underground and absorb water; carrot and radish are swollen taproots.

Question 5. Soaked seed kept in a freezer cannot germinate as it does not get adequate warmth.
Answer: True
In simple words: Seeds need suitable warmth along with water and air to germinate; freezing temperatures prevent growth.

Exam Tip: The three essential conditions for germination are water, air (oxygen), and suitable warmth.

QVI. Choose the right answer:

Question 1. Which of the following is a tuberous root?
(a) onion      (b) potato      (c) radish
Answer: (c) radish
Radish is a modified root that stores food, whereas onion and potato are modified underground stems.
In simple words: Radish grows underground as a root, while potato and onion are underground stems.

Exam Tip: Distinguish carefully between root vegetables (carrot, radish, beet) and stem vegetables (potato, ginger, onion).

Question 2. Which of the following is a dicotyledonous seed?
(a) rice      (b) pea      (c) wheat
Answer: (b) pea
Pea seeds easily split into two equal halves (cotyledons), making them dicots. Rice and wheat are monocots.
In simple words: Seeds that split into two halves are dicots like peas and beans.

Exam Tip: Pulses and beans are generally dicots, while cereals and grains are monocots.

Question 3. Which of the following crop is grown in cool climate?
(a) carrot      (b) brinjal      (c) pumpkin
Answer: (a) carrot
Root vegetables like carrots, radishes, and cabbages grow well in rabi (winter/cool) seasons.
In simple words: Carrots thrive in cooler weather compared to summer crops like pumpkins.

Exam Tip: Connect winter (rabi) crops with cool climates and summer (kharif) crops with warm, rainy climates.

QVII. Identify the seed and name the agent which help in the dispersal of these seeds:

Question 1. Identify the seed and the agent of dispersal for items 1 to 4 shown in the figures.
Answer:
1. Dandelion - Dispersed by Wind (Anemochory)
2. Lotus (or Coconut) - Dispersed by Water (Hydrochory)
3. Xanthium (or Pea pod / Burr) - Dispersed by Animals (Zoochory)
4. Cherry (or Berry) - Dispersed by Animals/Birds (Zoochory)
In simple words: Seeds have special features like hair, hooks, or fleshy fruit to travel by wind, water, or animals.

Exam Tip: Match seed adaptations: feathery/light = wind, spongy/fibrous = water, hooks/spines/edible fruit = animals.
