The growth of animals प्राण्यांची वाढ
A kid and a fully grown goat are not very different to look at. There is not much
difference between a kitten and an adult cat. These babies grow in their mother’s tummy
and are born from the mother’s tummy, too. These animals do not lay eggs.
But some animals like crows, spiders, lizards lay eggs
एक लहान आणि एक पूर्ण वाढलेली बकरी यांच्यात खूप भिन्न काही नाहीएक मांजरीचे पिल्लू आणि एक मांजर यांच्यात फरक. काही नाही
हे बाळ त्यांच्या आईच्या पोटात वाढतात आणि आईच्या पोटातून जन्मतात.हे प्राणी अंडी देत नाहीत.
पण काही प्राणी जसे कावळे, कोळी,सरडे अंडी घालतात .
A hen sits on her eggs to hatch them. The fully grown chick breaks the eggshell and comes out.
Egg, caterpillar (larva), chrysalis (pupa) and adult are the four stages of
The life cycle of a butterfly.
The Plain Tiger butterfly lays its eggs on the leaves of the milkweed plant.
The larva emerges from the egg. It is called the caterpillar.
When the growth of the caterpillar is complete, it enters the pupa stage during which it lives inside the chrysalis. The adult butterfly emerges from the chrysalis. It has six long legs and four attractive wings
कोंबडी तिच्या अंड्यांना उबवण्यासाठी बसते. पूर्णतः विकसित कोंबडी अंड्याचे तुकडे करते आणि बाहेर येते.
अंडी, सुरवंट (लार्वा), क्रिसालिस (प्यूपा) आणि प्रौढ हे चार चरण आहेत
फुलपाखरूचे जीवन चक्र.
प्लेन टायगर फुलपाखरू आपल्या अंडी दुधाच्या बीडच्या पानांवर ठेवते.
अंड्यातून अळ्या बाहेर येतात. त्याला सुरवंट म्हणतात.
सुरवंटची वाढ पूर्ण झाल्यावर ते पुपाच्या अवस्थेत प्रवेश करते
ज्या दरम्यान तो क्रिसालिसच्या आत राहतो.
प्रौढ फुलपाखरू क्रिसालिसमधून उदयास येते. त्याचे सहा लांब पाय आणि चार आकर्षक पंख आहेत
Question 1. It takes 20 – 22 days for a chick to emerge from a hen’s egg. Would the young ones of other birds also take the some number of days to hatch?
Answer:No, The number of days taken by different birds to hatch the eggs are different. So even if the hen takes 20-22 days to hatch its eggs different birds would take different number of days to hatch their young ones. For example, a sparrow takes 10 to 14 days while a penguin takes about 62 days to hatch the young ones. the young ones of other birds would not take the same number of days to hatch.

Question 3. When you take a bunch of a leafy vegetable to sort it, you may find hole of different sizes in the leaves. Some leaves may have been nibbled at edges. What do you think in the reason for that?

Question 4.-Which changes take place inside the chrysalis of the plain Tiger butterfly?
Answer: The Pupa of a butterfly is also called a chrysalis. It remains inside the chrysalis for the next eleven or twelve days. It does not eat anything during this stage.
