1. Put a (✔) for true and a (x) for false. Give a reason for your answer.
a. All animals move with legs.
Reason __________________________
b. Plants do not move from place to place, but their body parts may move.
Reason __________________________
c. Living things get energy from food.
Reason __________________________
d. Air is necessary for living things.
Reason __________________________
e. When you feel cold you wear a sweater, but a cow cannot do this. Therefore a cow is not a living thing.
Reason __________________________
f. Plants cannot breathe.
Reason __________________________
g. All plants reproduce and seeds.
Reason __________________________
h. Plants do not have sense organs, so they cannot feel.
Reason __________________________
Answer (2)
a. All animals move with legs.
False (X)
Reason: Not all animals use legs for movement. For example, snakes slither using their muscular bodies, fish swim using fins, and birds can fly with wings.
b. Plants do not move from place to place, but their body parts may move.
True (✔)
Reason: While plants are rooted and do not move from their location, parts like leaves and flowers can move. For example, sunflowers turn towards the sun, showing movement of parts.
c. Living things get energy from food.
True (✔)
Reason: All living organisms need energy to survive, grow, and reproduce. Plants produce their own food through photosynthesis, while animals eat plants or other animals to get energy.
d. Air is necessary for living things.
True (✔)
Reason: Air, particularly oxygen, is essential for the respiration process in most living organisms, which in turn provides the energy required for various life processes.
e. When you feel cold you wear a sweater. But a cow cannot do this. Therefore a cow is not a living thing.
False (X)
Reason: A cow is a living thing just like humans. It may not use clothing to keep warm, but it has its own biological mechanisms, such as growing thicker fur in colder months, to regulate its body temperature.
f. Plants cannot breathe.
False (X)
Reason: Plants do "breathe" in the sense that they take in carbon dioxide and release oxygen through the process of photosynthesis during the day, and they respire by taking in oxygen and releasing carbon dioxide all the time.
g. All plants reproduce and seeds.
False (X)
Reason: Not all plants reproduce by seeds. Some, like ferns and mosses, reproduce using spores.
h. Plants do not have sense organs, so they cannot feel.
False (X)
Reason: While plants do not have sense organs like animals, they can respond to stimuli such as light, gravity, and touch. For example, the Venus flytrap closes its leaves when touched, showing that plants can indeed "feel" or respond to stimuli.
The answers to the statements mostly highlight that while some beliefs may seem true at first, such as plants being immobile, they actually exhibit forms of movement. Additionally, living organisms exhibit various characteristics that confirm they are living, irrespective of their lack of traditional senses or locomotion. Overall, the distinctions between plants and animals demonstrate the diversity of life forms and their unique adaptations.
