shoot system

consists of vegetative, or non-reproductive parts lie leaves and stems, and reproductive parts like flowers and fruits

root system

supports plants and absorbs water and minerals, usually underground.

merismatic system

found in meristems. cells either undifferentiated/incompletely differentiated that contribute to plant growth or divide.

permanent tissue

plant cells that no longer divide

apical meristems

meristem tissue at tips and stems of roots that enable plant to grow in length

lateral meristems

grows thickness in a maturing plant

intercalary meristem

only in monocots at base of leaf blades and at nodes. let's monocot leaf blades grow in length.

dermal tissue, vascular tissue, and ground tissue

three types of plant tissues

dermal tissue

covers and protects plants, the outermost layer of plants.

vascular tissue

transports water, minerals, and sugars around the plants.

ground tissue

photosynthesis site, stores water and sugar, supports vascular tissue.
