Cells Year 8

all about cells and the cell theory

where is the cell membrane found

found in both cells

what is the function of cell membrane

holds & protects the cells, controls what substances are allowed to enter & leave as it is semi-permeable

where is cytoplasm found

found in both cells

what is the function of cytoplasm

a watery gel-like material that contains other organelles

where is mitochondria found

found in both cells

what is the function of mitochondria

breaks down glucose to create energy

where is ribosomes found

found in both cells

what is the function of ribosomes

smallest organelles, found on the endoplasmic reticulum or freely in the cytoplasm, builds proteins

where is rough & smooth endoplasmic reticulum found

found in both cells

what is the function of rough & smooth endoplasmic reticulum

forms pathways that allows materials to be quickly & easily moved around

where is the vacuole found

found in both cells

what is the function of the vacuole

an enclosed sac, filled with anything the cell needs to separate. animals have many small while plants have one large

where is the lysosomes found

found mostly in animal cells

what is the function of lysosomes

digestive juices that breaks down things the cell doesn't need

where is the golgi body found

found in both cells

what is the function of the golgi body

package up things such as hormones & proteins to be transported, transports around/out the cell

where in the nuclear membrane found

found in both cells

what is the function of nuclear membrane

supports & protects the nucleus, controls what substances are allowed to enter & leave the nucleus

where is the nucleus found

found in both cells

what is the function of nucleus

stores DNA in eukaryotic, regulates & controls all the cell activities

where is the chromosomes found

found in both cells

what is the function of chromosomes

23 pairs of chromosomes, 23 pairs of chromosomes in the nucleus of each cell

where is the cell wall found

found in plant cells

what is the function of the cell wall

outer layer on top of the cell membrane, make the cell stiff & strong, shapes and protects the cell

where is the chloroplasts found

found in plant cells

what is the function of chloroplasts

contains chlorophyll which captures energy from sunlight & used too produce for cells using photosynthesis, usually green

first component of cell theory

all organisms are made up of one or more cells

second component of cell theory

cells are the building blocks of living things

third component of cell theory

cells come from pre-existing cells
