| What are the M and the S in the life processes list? | Movement and Sensitivity |
| What are the two Rs in the life processes list? | Respiration and Reproduction |
| What are the G, the E and the N in the life processes list? | Growth, Excretion and Nutrition |
| The basic building block of animals and plants is the ......? | Cell |
| Animal cells and plant cells both contain........ | Cell membrane, Cytoplasm and Nucleus |
| What do plant cells contain that are not found in animal cells? | Chloroplasts, vacuoles and cell walls |
| What does the Cell membrane do? | Controls what substances can get into and out of the cell |
| What is the Cytoplasm and what does it do? | Jelly-like substance, where chemical reactions happen. |
| What does the Nucleus do? | It controls what happens inside the cell - it is not a 'brain' |
| What is Chloroplast and what does it do? | Where photosynthesis happens – chloroplasts contain a green substance called chlorophyll. |
| What is the Vacuole and what does it do? | Contains a liquid called cell sap, which keeps the cell firm. |
| What is the Cell Wall and what does it do? | Made of a tough substance called cellulose, which supports the cell. |
| What do Red Blood Cells do and what are their special features? | Their function is to carry oxygen. They have a large surface area, for oxygen to pass through and contain haemoglobin, which carries the oxygen. |
| What do Nerve Cells do and what are their special features? | They carry nerve impulses to different parts of the body. They are long, they have connections at each end to join to other nerves and they can carry electrical signals. |
| What do Female reproductive cell (egg cells) do and what are their special features? | They join with male cell to form an embryo. They provide food for the new cell that's been formed. It is large and contains lots of cytoplasm. |
| What do Male reproductive cells (sperm cells) do and what are their special features? | They join female cell and form the embryo. They have a long tail for swimming and a head for getting into the female cell. |
| What do Root hair cells do and what are their special features? | They absorb water and minerals. They have a large surface area. |
| What do Leaf cells do and what are their special features? | They absorb sunlight for photosynthesis. They have a large surface area and lots of chloroplasts. |
| What are tissues in plants and animals? | They are a group of cells with a similar structure and function, which all work together to do a particular job. |
| Give some examples of Animal tissues | Muscle, the lining of the intestine, the lining of the lungs |
| Give some examples of Plant tissues | Phloem (tubes that carry dissolved sugar around a plant), root hair tissue (for plants to take up water and minerals from the soil) |
| How is an organ different from a tissue? | An organ is made from a group of different tissues, which all work together to do a particular job. |
| Give some examples of animal organs | Heart, lung, stomach, brain |
| Give some examples of plant organs | Leaves and roots. |
| What is an organ system? | An organ system is made from a group of different organs, which all work together to do a particular job. |
| Give some examples of Animal Organ Systems | Circulatory system, respiratory system, digestive system, nervous system, reproductive system. |
| Give some examples of Plant Organ Systems | The shoot system, which is above ground and includes the organs such as leaves, buds, stems, flowers and fruits. The root system is below ground, and includes the roots, tubers, and rhizomes. |
