Q: Do animals have chlorophyll?
A: No, animals do not have chlorophyll. Chlorophyll is present in plants and is necessary for the process of photosynthesis.
Q: What is respiration?
A: Respiration is the process of inhaling oxygen and exhaling carbon dioxide, which is necessary for living things to produce energy and carry out their life processes.
Q: How do plants and animals differ in their means of respiration?
A: Animals have specific organs for respiration, while plants respire through stomata on their leaves.
Q: What are excreta?
A: Excreta are waste substances formed during the various processes that take place in the bodies of animals.
Q: What is excretion?

Q: Do animals have specific organs for excretion?
A: Yes, animals have specific organs for excretion, such as the kidneys and urinary bladder in humans.
Q: What is the responsiveness to stimuli?
A: The responsiveness to stimuli is the ability of living things to respond to a stimulus, which is an event that occurs in their surroundings.

A: The lifespan of a giant turtle found on the Galapagos Island in South America is about 170 years.
Q: What are living things made of?
A: Living things are made of small units called cells.
Q: What are the two types of living things based on the number of cells they are made of?
A: Living things are either unicellular or multicellular organisms.
Q: What are some examples of unicellular organisms?
A: Some examples of unicellular organisms are amoeba and some other microorganisms.
Q: Are all the characteristics of living things seen in every cell of a living thing?
A: Yes, all the characteristics of living things are seen in every cell of a living thing, whether it is unicellular or multicellular.
Q: What are some examples of harmful animals and plants to humans?
A: Examples of harmful animals include mosquitoes, flies, cockroaches, mice, rats, lice, ticks, poisonous lizards, spiders, snakes, scorpions and wild elephants.
