Student B and D because both organisms breath with lungs.

Student C and Student D because both organisms can live in water.

Student A and Student D because both organisms have 4 legs and are slimy.

Mosses

Ferns

Fruit trees

Algae

The cell would not have a rigid structure.

The cell would not have a "control center" to instruct other organelles.

The cell would not be able to produce its own energy for food.

The cell would not have a round shape.

A spider spins a web.

A dog has spots on its fur

A human drives a car

A tree has green leaves

flowering, because squirrels and other living things make their homes there and use the tree for food.

fruit bearing, because squirrels and other living things make their homes there and use the tree for food.

non-flowering, because the tree creates pine cones which help it reproduce.

non-seed bearing, because the tree creates pine cones which help it reproduce.

The shape of the cell because both a sunflower and frog have a rigid structure due to a cell membrane.

The presence of chloroplasts because both sunflower and frogs cells need chloroplasts to produce energy (food).

The shape of the cell because both a sunflower and frog have a rigid structure due to a cell wall.

The presence of a cell membrane because both a sunflower and frog have cells that allow nutrients to flow in and out of a cell.

The cell sample could have come from moss because moss’ cells have rounded shaped cells.

The cell sample could have come from a bird because bird’s cells have rounded shaped cells.

The cell sample could have come from moss because moss’ only have a thin membrane that surrounds the cell.

The cell sample could have come from a bird because bird’s cells have tiny green structures.
