2  Organism: A living thing  Cell: The smallest unit of living things that carry out the basic processes of life

3  Round shape, smaller  No cell wall, only a cell membrane  Some have many small vacuoles, and others may not have any vacuoles  Gets energy from other animal/plant cells

4  Box-like shape, larger  Have an additional outer covering around the outside (cell wall)  Usually have one large, central vacuole  Makes own food in chloroplasts (green structure, contains chlorophyll)  Gets energy from the sunlight

5  Tissue: similar cells working together at the same job, or function  Organ: a group of tissues that work together to perform a specific function (example: heart, liver, brain, skin)  Organ System: organs that work together to perform a certain function (example: circulatory, digestive, respiratory) Organ TissueOrganOrgan System

6  Scientists organize organisms by sorting, or classifying, them into groups according to shared characteristics  Kingdoms are grouped by internal form and structure  The narrowest (smallest) group an organism can be classified into is a species

8  Vessels that run up and down the body  Vascular tissue carries water and nutrients from the plants roots up to its leaves; it also moves sugars made in the leaves to other parts of the plant  Typically a taller plant

9  Smaller plant  Remain small and close to the ground, where they soak up water directly Have you seen moss or trees that look like this?

10  Stems come in 2 basic forms  Soft stems  Woody stems  Soft stems: not as strong as woody stems; soft, green, can bend (less likely to be damaged in a storm)  Woody stems : stronger than soft stems; hard, brown (more likely to be damaged in a storm because they can’t bend and they grow tall, which makes it easier to be struck by lightning).

11 Soft stemWoody stem

12  Phloem: moves sugars that are made in the plant’s leaves to other parts of the plant; transports sugars up from one part of a plant to another  Xylem and phloem cells are produced in the cambium, then move inward.

13  The leaves of a plant have the important function of carrying out photosynthesis, or the process of making food.

14  The top surface of a leaf has a waxy cuticle, a waterproof layer that prevents moisture from evaporating  Which could survive longer without water: a thick cuticle or a thin cuticle? How could you test this?

15  Asymmetrical: cannot be divided into mirror images.  Radial Symmetry: All body parts are arranged around a central point; this type of organism has more than one line that divides the organism into 2 mirror images.

16  Monotreme: a mammal that lays eggs (examples: duck-billed platypus, spiny anteater)  Marsupial: a pouched mammal; give birth to partially developed offspring (examples: kangaroos, koala bears)  Placental mammal: the young develop within its mother (examples: humans, dogs, tigers, elephants, whales)

17  Skeletal System: bones, tendons, ligaments  Muscular system: provides the power to produce movement  Digestive system: long tube in which food is broken down into nutrients an organism can use Skeletal System Muscular System Digestive System

18  Esophagus: a muscular tube that contracts and expands to squeeze chewed food down the stomach  Bronchi:small branch-like tubes inside the lungs, which empty into the alveoli.  Alveoli: very thin-walled air sacs located at the tips of the bronchi
