1.2 - Animal and plant cells

size of average animal cell

10 - 30 micrometers

nucleus

• controls all activities in the cell

• surrounded by nuclear membrane

• contains genes in chromosomes

cytoplasm

• liquid gel that holds organs

• where chemical reactions take place

cell membrane

• controls passage of substances in/out of cell

mitochondria

• where aerobic respiration takes place

• very small

ribosomes

• where protein synthesis takes place

chloroplasts

• green - contain chlorophyll

• where photosynthesis happens

• only in plant cells

Permanent vacuole

• space in cytoplasm filled with cell sap

• Keeps cell rigid

• only in plant cells

cell wall

• made of cellulose

• strengthen the cell

Organelles in plant and animal cells

• cell membrane

• mitochondria

• ribosomes

• cytoplasm

Organelles in only plant cells

• cell wall

• permanent vacuole

• chloroplasts
