TEKS 7.12C recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organism
Levels of Organization Notes
*Go over notes below and then have students use response cards to identify the
pictures on the power point as cells, tissues, organs, organ systems or organisms.
*Two sets of response cards can be copied on different colored paper to have students
differentiate if the structures are found in plants (green) or animals (blue or pink).
*Response cards can be use in strips or can be laminated and then taped on popsicle
sticks or straws.
Cell: Basic unit of structure and function in all living organisms.
Examples: animals- muscle, bone, nerve, blood, skin, egg,
sperm, fat
plants- epidermal, parenchyma, spongy, cambium,
xylem, phloem
Tissue: Similar cells working together to perform a specific
function.
Examples: animals- muscle, nervous, epithelial, connective
plants- dermal, ground, vascular
Organ: Different tissues working together to perform a
specific function.
Examples: animals- brain, stomach, intestines, heart, lungs,
liver, etc…
plants- leaves, buds, flowers, fruits, stems, roots,
tubers, rhizomes
Organ system: Group of different organs working together to
perform a particular set of functions.
Examples: animals- circulatory, respiratory, nervous, digestive,
reproductive, muscular, skeletal, etc…
plants- shoot, root
Organism: Anything living that is made of cells and needs
energy, excretes wastes, grows, responds,
reproduces, and uses gases.
Examples: animals, plants, bacteria, fungi, protists,
monerans
