Living Things And Cells Flashcards
Feeding
Animals do not make there own food. They get their food by eating plants and other animals. Plants make their own food
Photosynthesis
The way in which plants make food is called photosynthesis. They need a green dye called chlorophyll. This is why plants are green
Excretion
Excretion is the removal of waste made in the body, from the body. Animals excrete carbon dioxide, water,urea and salts
Reproduction
Reproduction is being able to make new individuals of the same kind. E.g. babies, new plants, puppies
Growth
Growth results from cell division.
Cell membrane
Very thin layer that surrounds the cell. It holds cell contents in place and controls what passes into and out of the cell
Cytoplasm
The watery liquid found between the nucleus and the cell membrane
Nucleus
Is normally round. It acts as the control centre of the cell. It has the DNA.
Cell wall
Found outside the cell membrane of a plant cell. Gives strength to the cell.
Mitochondria
Supply energy to the cell
Vacuole
Space containing water sugar and wastes gives strength to the cell
Chloroplasts
Contain chlorophyll to help make food using sunlight (photosynthesis)
Invertebrates
Animals that do not have a backbone are called invertebrates E.g. worm
Vertebrates
Animals that have a backbone are called vertebrates E.g. dog vertebrates are normally bigger and more complex animals than invertebrates
