When conditions favour individuals exhibiting one extreme of a phenotypic range.

• When conditions favour individuals with phenotypes at both ends of the phenotypic range.
• ex) birds with medium sized beaks are inefficient at cracking soft and hard seeds.

• When both extremes of a phenotypic range and infavourable.
• ex) human babies who are light or heavy.

• Organisms that obtain carbon from carbon dioxide
• ex) plants

• Organisms that obtain carbon from organic molecules
• ex)humans

Organisms that obtain energy from light

Organisms that obtain energy from chemicals

Organisms that obtain carbon from carbon dioxide and energy from light.

Organisms that obtain carbon from carbon dioxide and energy from chemicals.

Organisms that obtain carbon from organic molecules and energy from light

Organisms that obtain carbon from organic molecules and energy from chemicals

gametes fuse to form a zygote

Gametes

A group of tissues integrated to perform one or more functions in an organism

A group of similar cells that perform a particular task in an organism

The engulfing or expulsion of particles through the fusion of vesicles with the plasma membrane

• The outer surface tissue of plants.
• Protects from injury
• Exchanges materials with the environment

B.

Platelets. They carry enzymes that cause clotting.

White blood cells. They attack invaders in the body.

Red blood cells. They transport oxygen.

Chitin

Proteins that allow larger molecules to pass across the plasma membrane. They are very specific and work through diffusion.

• Bacillus
• Coccus
• Spirillum

• Animalia
• Plantae
• Fungi

When a blood cell in a hypertonic environment loses too much water and collapses

• Oxygen
• Carbon Dioxide
• Water

Embryonic tissue. Necessary for growth and repair.

Composed of Xylem and Phloem. Forms tubules for the transport of water and nutrients throughout the plant body.

The diffusion of water across a selectively permeable membrane.

When a plant cell in a hypertonic environment loses too much water and collapses.

The transport across the cell membrane of a substance against the concentration gradient. Used to maintain a different concentration from the surrounding environment. Requires energy (ATP)

The cycling of cytoplams in a cell.

When a cell in a hypotonic environment gains too much water and bursts.

A.

• Neither vascular or dermal tissue, necessary for photosynthesis, food storage and mechanical support.
• Pith, Cortex and Mesophyll are all ground tissue.

Proteins embedded in the phospholipid bilayer that allow specific small molecules to pass through diffusion.

A particular sequence of connected reactions

Ribosomes form around tRNA "translating" the nucleotide sequence into an amino acid sequence know as a polypeptide. Occurs in the cytoplasm.
