Cellular to Multicellular Learning Targets and Success Criteria
*Starred items are covered on the midterm.
LS 6-1 We are learning to describe that cells are the basic
units of life.
*We are looking for a way to group living things (single-celled or
multicellular).
Single-celled--one cell only (unicellular); examples are amoeba and bacteria - usually
need a microscope to see them
Multicellular--many cells; examples are plants, animals, fungi - do not need a
microscope to see them
*We are looking for organelles (parts within cells) that can be found in
both plant and animal cells (nucleus, cytoplasm, mitochondria,
ribosome, vacuole, plasma/cell membrane, lysosome).
● nucleus--the control center
● cytoplasm--jelly like substance that holds organelles in place
● mitochondria--makes energy, power of the cell
● ribosome--make proteins
● vacuole--storage of food, water, waste
● cell membrane--controls what goes in and out of cell
● lysosome--gets rid of unwanted substances
● endoplasmic reticulum - transportation system of the cell
*We are looking for organelles (parts within cells) that can be found only
in plants (cell wall, chloroplast).
cell wall--protect and support plant cell
chloroplast--where plants make food (photosynthesis)

Cellular to Multicellular Learning Targets and Success Criteria
LS-6-2 We are learning to explain that all cells come
from other cells (The Modern Cell Theory).
*We are looking for theories that have changed and developed over time.
The Modern Cell Theory states that:
Cells come from other cells
Cells are the basic unit of life
Cells are found in all living things
Robert Hooke - looked at cork, named what he saw “cells”
Anton Van Leeuvenhook - first saw single celled organisms (bacteria)
Francisco Redi - conducted experiments that disproved Spontaneous
Generation
Spontaneous Generation - a theory that living things came from nonliving
things. For example: maggots came from rotting meat and mice came from
underwear and wheat husks
We are looking for cells to make more cells by a process called mitosis.
Mitosis is when one cell splits and reproduces into 2 identical cells when it reaches its
size limit. Sometimes the terms parent cell and daughter cell are used.
We are looking for cells to reproduce and pass on genetic material
(chromosomes) which is necessary for the continuation of the species.
Chromosomes are found in the nucleus of the cell. Chromosomes make a copy of
themselves before they split into two. Chromosomes transfer genetic information to
each new cell. Chromosomes tell the skin cells to make more skin cells, and bone cells
to make more bone cells.
We are looking for cells to multiply for growth and repair.
We grow because new cells are formed. Cells continue to divide and increase in
number for growth. Cells reproduce to replace damaged or dead cells.

LS 6-3 We are learning to explain that cells have certain
jobs (functions) that help to keep organisms alive.
We are looking for the jobs a cell does that are needed to keep organism
alive.
● Maintaining homeostasis (balance) Ex: temperature at 98.6
● Gas exchange - respiration in mitochondria, photosynthesis in chloroplast
● Energy transformation- nutrition, digestion, changing food into energy
● Movement of molecules/materials - food, air, energy moved around the
cell
● Disposal of waste - excretion, remove unwanted material
● Synthesis of new molecules (protein building) - growth, create proteins
● Information feedback and movement - communication within the cell
Osmosis and Diffusion
osmosis - the diffusion of water, moving into or out of a membrane.
diffusion - when molecules move from an area of higher concentration to an area of
lower concentration.
*We are looking for the work of a cell to be the controlled by the nucleus
(located in the cytoplasm of the cell).
The nucleus is the control center of the cell.

Tea bag and sand
Potatoes and salt water

LS 6-4 We are learning to describe that all living systems
have structure (design) and function (a job to do).
*We are looking for living systems to have: cells, tissues, organs, organ
systems and organisms.
Levels of Organization:
● Cell - basic unit of life - simplest - smallest
● Tissue - group of cells
● Organ - group of tissues (heart ,nerves, muscles, bones, stomach)
● Organ System- group of organs (circulatory system, nervous system, muscular
system, skeletal system, digestive system)
● Organism- group of organ systems- most complex
REMEMBER THE SONG!
*We are looking for classification system of organisms (six kingdoms).
6 Kingdoms:
● Plant- has cell wall and chloroplasts, multicellular, limited movement,
producer
● Protist- one-celled (Amoeba) with a nucleus
● Eubacteria- no nucleus, one-celled, found in our bodies
● Archaebacteria- no nucleus, one-celled, found in extreme environments
● Animal- multicellular, no cell wall or chloroplast, consumer
● Fungi- decomposers (mushrooms), multicellular, with a nucleus
We are looking for comparisons of body plans and symmetry of the
outsides (external) body structures of different organisms.
Bilateral Symmetry - one line of symmetry down the middle creating 2 identical sides.
Examples: people, spider, fish, bird, dog
Benefits of bilateral symmetry include: escape predators, find food, balance and
movement
Radial Symmetry - parts of body are arranged around one central point.
Example: starfish, jellyfish
Benefits of radial symmetry: movement in all directions
Asymmetrical - no symmetry at all. Example: sponge

We are looking for comparisons of body plans and symmetry of the
insides (internal) body structures of different organisms.
Internal structures of an earthworm include:
gizzard - grinds the food to aid in digestion since the worm has no teeth
anus- gets rid of waste
mouth- intake of food
intestine- digestion
crop- storage
hearts (5)- pump blood throughout the worm
We compared these structures to those of humans, fish and plants in the activity
called Squirmin Herman.
We are looking for the processes (respiration, circulation) that
aid/support the function (gas exchange).
Respiration - energy is released in the mitochondria. Sugar and oxygen enter the cell
and the waste product is carbon dioxide. This is an example of gas exchange.
Photosynthesis - the waste product of respiration (carbon dioxide) is needed in the
chloroplasts of a plant cell for photosynthesis in order for the plant to make its own
food (sugar/glucose)
