STAAR Review

• Category 4
• Students demonstrate an understanding of the
  structures and functions of living organisms and
  their interdependence on each other and their
  environment.

2
Animal vs. Plant Cells

• Animal cells

Plant cells

• Vacuole (storage)
• Cell wall
• Mitochondrion
• Chloroplast
• Nucleus
• Cytoplasm
• Cell membrane

3
Organization of Living Things

• Cells
• Tissues
• Organs
• Organ systems
• Organisms
• Populations

What's the Function?

• Circulatory
• Transport food oxygen to cells
• Transport waste products from cells
• Respiratory
• Provide oxygen to the blood
• Remove carbon dioxide from the blood
• Skeletal
• Support, protection, and movement

7.12B

What's the Function?

• muscular
• Body Movement
• Movement of blood and food
• digestive
• Break down food to nutrients
• Deliver nutrients to circulatory system
• excretory
• Remove wastes from the body including excess water

What's the Function?

• reproductive
• Pass genetic information to offspring
• Continue the species
• integumentary (skin)
• Protection
• Reduce water loss
• nervous
• Process information send instructions

What's the Function?

• endocrine
• control homeostasis
• regulate bodily functions like metabolism
• control growth
• Control development
• reproduction

Reproduction

• Inherited traits controlled by _1?_.
• Found in _2?_, located on _3?_ found within the
  _4?_ of a cell.
• Asexual vs. sexual
• Which creates more diversity?

  look fresh. If they lose turgor pressure, they
  become wilted. How is turgor pressure maintained?
• A. air is pumped into flowers
• B. water moves into cells
• C. minerals turn to crystals
• D. more sugar is produced
• E. water is pumped out of the cells
• F. more sugar is consumed

Discussion

• Given two organism that consume the same things
  in aa forest ecosystem, what would happen to the
  organisms if a drought caused a major loss of
  trees?

Succession

• What is it?
• series of predictable changes in a community that
  occur over time
• Begins on new land such as a volcanic island
• After major event volcanic eruption, fire
• 2 types
• Primary start with no ecosystem existing
  1stpioneer species (lichens mosses) then
  grasses, shrubs and finally trees
• Secondary occur after a disturbance such as
  farming or logging regrowth of grasses, shrubs,
  small then larger trees

Succession
Types of catastrophes

• volcanic eruption
• forest fire
• deforestation
• land cleared for agriculture

Organism Structures

• A dichotomous key to these six species is shown.
  Complete the missing information for sections
  5.a. and 5.b. so that the key is complete for all
  six species.

Organism Structures

• Using the dichotomous key, classify an organism
  that has small or no wings, shorter rear legs,
  not a horned head and small eyes.

Explain the Relationships

• Producer Consumer
• Predator Prey
• Parasite Host

Organisms Environmental Change

• Polar bears are dependent on sea ice to hunt
  seals and to move from one area to another.
• What might happen to the polar bears if global
  climate change continues?

Differentiate between Natural Selection
Selective Breeding

• Both are ways traits are passed from parent to
  offspring
• Natural Selection
• Referred to survival of the fittest
• Only the most adapted organisms live to pass on
  their genes
• Peppered moth and air pollution
• Selective Breeding
• Human controlled
• We physically breed for the traits we WANT in the
  offspring
• dairy cows
