What is the first stage in the plant lifecycle where a seed begins to grow into a tiny plant?
Germination
What are microorganisms?
Microorganisms are tiny living organisms that are too small to be seen with the naked eye.
What is the main function of the heart?
The main function of the heart is to pump blood throughout the body.
What are the primary organs involved in the respiratory system?
The Lungs
What is a habitat?
A habitat is a place where a plant or animal lives.
Name two examples of living things found in a garden.
Two examples of living things in a garden are flowers and insects.
In which part of a plant does photosynthesis primarily occur, helping the plant to make its own food?
The leaves
What tool or device could be used to look at micro-organisms?
A Microscope
What is the purpose of blood vessels in the circulatory system?
Blood vessels transport blood throughout the body, carrying oxygen and nutrients to cells and removing waste products.
What is the main gas we inhale when we breathe, and what gas do we exhale?
We inhale oxygen and exhale carbon dioxide.
What is the main source of energy for most living things on Earth?
The Sun
Explain what a food chain is and give an example.
A food chain shows how energy is transferred from one living thing to another. For example, grass -> rabbit -> fox.
What is pollination, and how does it contribute to the reproduction of flowering plants?
Pollination is the process of transferring pollen from the male part (anther) of a flower to the female part (stigma) of the same or another flower. It contributes to plant reproduction by allowing fertilization to occur, leading to the formation of seeds.
Why are microorganisms important in the process of making bread rise?
Microorganisms, particularly yeast, produce carbon dioxide gas during fermentation, which causes the bread dough to rise and become fluffy.
How will heavy exercise affect your heart rate?
It will increase it.
Explain the term "respiration" and how it differs from "breathing."
Respiration refers to the process by which cells use oxygen to produce energy, while breathing is the physical act of inhaling and exhaling air.
Define "mammals" and give an example of a mammal.
Mammals are animals that have hair or fur and give birth to live young. An example of a mammal is a cat.
What is a physical change, and provide an example.
What is a physical change, and provide an example.
Explain how the process of fertilization occurs in plants and what happens after fertilization to complete the plant's lifecycle.
Fertilization in plants occurs when pollen from the male part (anther) of a flower reaches the female part (stigma) of the same or another flower. After fertilization, the ovule in the flower's ovary develops into a seed, and the ovary develops into a fruit. This completes the plant's lifecycle.
What is the difference between bacteria and viruses?
Bacteria are single-celled living organisms with their own genetic material, while viruses are not considered living organisms.
How does diet and exercise affect the heart?
A healthy diet and regular exercise can improve heart health by reducing the risk of cardiovascular diseases like heart attacks and strokes.
What is the name of the thin, dome-shaped muscle beneath the lungs that helps with breathing?
The Diaphragm
What are the three main types of rock?
The three main types of rock are igneous (formed from cooling lava or magma), sedimentary (formed from compressed and cemented sediments), and metamorphic (formed from existing rocks that undergo heat and pressure).
What are the three states of matter, and describe their properties.
The three states of matter are solid (has a fixed shape and volume), liquid (has a fixed volume but takes the shape of its container), and gas (has neither a fixed shape nor volume).
In the plant lifecycle, how does seed dispersal help, and can you name different methods by which seeds are dispersed (spread)?
Seed dispersal helps plants spread to new areas and reduces competition among offspring. Different methods of seed dispersal include wind, water, animals (by ingestion or attachment to fur), and explosive mechanisms in some plants.
Explain how microorganisms can be both beneficial and harmful to humans.
Microorganisms are beneficial as they help in digestion, fermentation, and antibiotic production. However, some can be harmful, causing diseases like infections, food poisoning, and decay.
What is the difference between arteries and veins in terms of their function and structure?
Arteries carry oxygenated blood away from the heart and have thicker walls, while veins carry deoxygenated blood back to the heart and have thinner walls.
What is the connection between the respiratory system and the circulatory system in the body?
The respiratory system provides oxygen to the circulatory system, which then transports oxygen to body cells and returns carbon dioxide to the lungs for exhalation.
Explain magnetism and give an example of a magnetic material.
Magnetism is a force that attracts or repels certain materials. An example of a magnetic material is iron.
Describe the process of digestion in the human body. including the role of enzymes.
Digestion is the breakdown of food into smaller, absorbable molecules. Enzymes, like amylase and pepsin, help break down carbohydrates and proteins, respectively.
