Animals can walk, run, hop or crawl. How do they find their way? |
By using their eyes, ears, nose (or even antennae), this are also called sense organs. |
|
How do plants make food in their own leaves? |
Photosynthesis |
|
What are the 4 things needed in photosynthesis? |
1. Light 2. Water 3. Carbon Dioxide 4. Chlorophyll |
|
How do plants get energy from food? |
By a process (usually with oxygen) called respiration. |
|
All living things produce waste. What is the removal of waste from their bodies called? |
Excretion |
|
What are the 5 needs of living things? |
1. water 2. light and carbon dioxide 3. warmth 4. minerals 5. oxygen |
|
What is the part of the earth's surface where living things are found? |
Biosphere |
|
What are the two smaller groups under Protoctista? |
1. Protozoa - microscopic creatures made of 1 cell 2. Algae - simple plant-like organisms |
|
Give 3 examples of Fungi. |
Mushrooms, toadstools and moulds. |
|
What are the six divisions of plants? |
1. mosses and liverworts - plants with no roots 2. ferns - have proper roots, produce spores 3. conifers - trees with needle-shaped leaves/cones 4. flowering plants - flowers which produce seeds 5. monocotyledons - leaves with parallel veins 6. dicotyledons - leaves with a network of veins |
|
What are the two main groups of animals? |
Vertebrates and Invertebrates
|
|
What are the 8 animal groups under invertebrates? |
INVERTEBRATES 1. coelenterates - sack like body with tentacles 2. flatworms - flat body w/ cilia 3. annelid worms - body encircled w/ rings 4. molluscs - one coiled shell/two uncoiled shells ARTHOPODS: 5. crustaceans - hard outer skeleton 6. insects - 6 legs, 2 pairs of wings 7. arachnids - 8 legs, no wings 8. centipedes - many pairs of legs |
|
What are the 5 animal groups under vertebrates/chordates? |
1. bony fish - scale, fins, gills 2. amphibia - live on water/land 3. reptile - covered with hard/dry scales 4. birds - feathers and wings 5. mammals - hairy skin, young feed on milk |
|
What do you call the thick skin around the cell that allows only some things to pass through? |
A cell membrane. |
|
What controls what a cell does and how it develops? |
A nucleus. |
|
What is the jelly containing chemicals and filling up the cell? |
Cytoplasm |
|
What is the space between the cell that contains air, liquid or food particles? |
Vacuole. |
|
Describe the parts of a plant cell (5). |
1. cell wall of cellulose - covers cell membrane 2. cytoplasm - jelly w/ chemicals, fills the cell 3. stored food - starch 4. vacuole - all plants have this, the inside is filled with cell sap 5. chloroplasts - discs full of chlorophyll (trap light for photosynthesis) |
|
Differentiate plant cells from animal cells. |
ANIMAL : no cell wall, no chloroplast, sometimes have vacuole, different shapes PLANT: have cell walls, have chloroplasts, always have vacuole, few kinds of shapes |
|
What are tissues? |
Cells that do the same job group together and form tissues. |
|
What are the 3 other types of cells? |
1. muscle cells (they can tighten/relax) 2. nerve cells (carry messages) 3. red/white blood cells (carry oxygen and kill germs) --> A.K.A blood |
|
Give an explain 1 type of organ |
1. heart - pumps blood around the body 2. stomach - digests food 3. brain - controls the body |
|
An organism is made of different organs. These can work together to form organ systems. Give an example of an organ system. |
1. circulatory system - heart/blood vessels 2. digestive system - gullet, stomach, intestine 3. nervous system - brain, spinal cord, nerves |
|
What is diffusion? |
Movement of molecules that cause them to mix together. |
|
What is an active transport of molecules? |
This process uses energy to move the molecules to where it is needed in the plant. This occurs from an area of low concentration to a higher concentration. |
|
What is osmosis? |
When a weak solution is separated by a semi-permeable membrane, the diffusion of water (from a weak to a strong solution) occurs. |
|
What is meiosis? |
This is a type of cell division that results in 4 daughter cells (each with 1/2 the number of chromosomes from the parent cell), as in the production of gametes/plant spores. |
|
What is a diploid and haploid? |
Diploid - 46, complete Haploid - 23, one half |
|
What is mitosis? |
A cell division resulting in 2 daughter cells having the same number/kind of chromosomes from the parent nucleus. |
