Life Science

Photosynthesis, Organ Systems, Cells, Reproduction, Osmosis

Organisms things that have all the characteristics of life
cell smallest unit of life
unicellular living things only made of only once cell
multicellular living things that are made of two or more cells
Compound Microscope a light microscope that uses more than one lens
Robert Hooke created the microscope, named and observed cells
Cell theory states that all living things are made from one or more cells, smallest unit of life and all new cells come from preexisting cells.
proteins necessary for nearly everything that cells do
Lipids also known as fats, are protective barriers in cells
Carbohydrates store energy, provide structural support, are needed for communication between cells.
Cell membrane protects the inside of a cell from the environment
Cell wall stiff structure outside the cell membrane
Nucleus directs all activities contains DNA
Chloroplasts use light energy to make food called glucose in plants
Osmosis diffusion of water molecules through a membrane
Diffusion movement of substances from an area of higher concentration to an area of lower concentration.
Cellular respiration process of converting energy in food molecules into a usable energy form called ATP (humans)
Photosynthesis process in which plants make their own food and produce oxygen.
asexual reproduction process in which organisms can reproduce offspring on their own
sexual reproduction process where organisms work together to create offspring
heart muscle/organ that aides in the transport of blood
Circulatory System heart, veins and blood that transport nutrients and waste through the body
Digestive System system of organs that breaks down food
Nervous System brain, spinal cord and nerves that send messages to and from the brain.
Skeletal System system of bones that provide the structure to your body
Excretory System organs in which help remove waste from the body
Muscular System system of muscles that allow your body to flex and extend
Respiratory System system of organs that allow for breathing.
Mitosis the process in which the nucleus of a cell divides.
Meiosis division of a diploid cell which creates four haploid cells. Occurs during formation of sex cells.
