2. Cactus – Pine – Oak – Apple (Cactus grows in deserts, others grow on mountains/plains)
V. Match the following
| 1. Cactus | A. grows on land |
| 2. Peepal | B. grows in the desert |
| 3. Lotus | C. grow on mountains |
| 4. Pine | D. grows in water |
1 → B 2 → A 3 → D 4 → C
VI. Answer the following questions in four or five sentences
1. Why do different plants grow in different habitats? Explain your thinking.
Answer: Different plants grow in different habitats because their structural requirements vary, and they adapt to their surroundings to survive. For example, a cactus needs very little water and thrives in a dry desert climate, whereas a lotus requires a continuous aquatic environment to live. The temperature, availability of water, and soil type of a place determine what kinds of plants can successfully grow there.
2. What problems would a terrestrial plant face if it grew in water?
Answer: If a terrestrial plant is grown directly in water, its root system will eventually rot due to a lack of proper aeration and excess moisture. Terrestrial plants lack the specialised, spongy air cavities that help aquatic plants float and respire in waterlogged conditions. Additionally, their leaves do not have a protective waxy coating, causing them to decay when submerged continuously.
3. Write a brief note on the uses of plants.
Answer: Plants are highly essential to life on Earth as they produce oxygen during photosynthesis, which all living creatures need to breathe. They provide humans and animals with major food sources like fruits, vegetables, grains, and nuts. Additionally, plants supply timber for construction, fibres like cotton for making clothing, and organic components for vital traditional medicines.
4. Look at these features: thick stem, very few leaves, stores water. To which habitat does this plant belong and why?
Answer: This plant belongs to the desert habitat. These features are specialised adaptations designed to survive in extremely dry regions with minimal rainfall. The thick, fleshy stem allows the plant to store significant quantities of water, while having very few or modified leaves (like spines) reduces the loss of water through transpiration.

2. Leaves (ఆకులు): Spinach, Amaranth, Cabbage
3. Flowers (పువ్వులు): Cauliflower, Broccoli, Banana flower
4. Stems (కాండం): Potato, Ginger, Colocasia
V. Answer the following questions in two or three sentences
1. What will happen to a plant if its roots cannot absorb water properly?
Answer: If the roots cannot absorb water properly, the plant will dry up and eventually die. Without water, the leaves cannot prepare food, and nutrients cannot be transported to the rest of the plant parts.
2. Why do you think the shoot system grows above the ground?
Answer: The shoot system grows above the ground to absorb maximum sunlight and carbon dioxide from the air, which are necessary for photosynthesis. Growing above ground also allows flowers to be pollinated by wind or insects and helps seeds disperse properly.
VI. Answer the following questions in four or five sentences
1. Draw diagrams and explain the different types of roots in plants.
(Draw two simple diagrams: one showing a thick single main root with thin hairs for the Taproot, and one showing a cluster of equal-sized fibrous roots spreading out like a bunch of grass.)
Answer: There are two main types of roots:
Answer: There are two main types of roots:
- Taproot System: Has a single, thick main root that grows deep into the ground, with smaller lateral roots growing sideways from it (e.g., Mango, Neem, Hibiscus).
- Fibrous Root System: Consists of a cluster of thin, fibre-like roots of similar size arising from the base of the stem, spreading shallowly in the soil (e.g., Paddy, Wheat, Grass).
2. Imagine a plant with strong roots but no leaves. Will it survive? Why or why not?
Answer: No, the plant will not survive for long without leaves. Leaves contain chlorophyll and are known as the food factories of the plant because they prepare food using sunlight, water, and air. While strong roots can hold the plant firmly and absorb water, the plant will eventually starve and die once its stored food reserves are depleted because it cannot produce new energy.
3. Carrot and grass plants grow in the same soil. Carrots grow deep and thick, while grass spreads widely. Explain how their root types help them survive.
Answer: The carrot plant has a taproot system that grows deep into the soil to absorb water from lower layers and store food, making it thick and fleshy. On the other hand, grass has a fibrous root system that spreads widely near the surface to anchor the plant firmly over a broad area, quickly absorbing surface water and preventing soil erosion. Both types allow the plants to effectively share the same soil without competing at the same depth.

V. Answer the following questions in two or three sentences
1. Some people pluck flowers unnecessarily from public gardens. Do you think this is right? Give reasons for your answer.
Answer: No, plucking flowers unnecessarily is wrong. Flowers enhance the natural beauty of gardens and public spaces for everyone to enjoy, and they serve as an essential food source for insects like bees and butterflies. Plucking them prematurely prevents them from turning into fruits and seeds.
2. Write different occasions on which we use flowers.
Answer: We use flowers during various traditional festivals, weddings, and birthdays for decorative purposes. They are also made into garlands for worship, used to welcome guests, and given as bouquets to express love, congratulations, or sympathy.
VI. Answer the following question
1. Describe a diagram of a flower and label its parts. Briefly describe its structure.
(Draw a simple flower cross-section showing the stalk and leaves at the base, the bright petals, and the centre reproductive structures.)
Answer: A typical flower consists of four main structural parts:
Answer: A typical flower consists of four main structural parts:
- Sepals: The green, leaf-like structures at the base that protect the budding flower.
- Petals: The bright, coloured, and often scented parts that attract insect pollinators.
- Stamen: The male reproductive part of the flower that produces pollen grains.
- Pistil (or Carpel): The central, female reproductive part that receives pollen and later develops into the fruit containing seeds.

- Food: Cauliflower and banana flowers are cooked as vegetables.
- Medicine: Saffron and clove buds provide organic medicinal extracts.
2. Write a brief note on the uses of plants.
Answer: Plants are crucial because they release oxygen into the atmosphere, which is essential for human survival. They supply us with basic dietary necessities such as grains, vegetables, and sweet fruits. Furthermore, their sturdy trunks offer timber for building furniture and homes, while their root networks tightly grip the earth to stop soil erosion.
3. Latha is suffering from a cough. Which medicinal plant do you suggest and why?
Answer: I would recommend drinking a warm extract of Tulasi leaves mixed with honey or Ginger tea. Tulasi leaves possess natural antibiotic, antiviral, and anti-inflammatory properties that help open up congested airways, soothe an itchy throat, and provide quick relief from coughing fits.
IV. Answer the following questions in five or six sentences
1. Carrots and grass are grown in the same soil. Carrots grow deep and thick, while grass spreads widely. Explain how their root types help them survive.
Answer: The carrot possesses a taproot system, consisting of a thick main taproot that tunnels vertically deep underground to fetch moisture from deeper layers while acting as a large storage locker for plant energy. Conversely, grass features a dense fibrous root system, stretching multiple delicate root threads out like a carpet just below the surface. This design helps the grass instantly capture morning dew or brief rain showers before it evaporates, while physically anchoring topsoil down tightly. By exploiting completely different depths of the same soil profile, both plants can live together without starving each other out.
